The Timing of Earnings Announcements and
Market Response to Earnings News
Abstract
In this paper, we investigate whether the timing of earnings announcements in the earnings
seasons affects market response to earnings surprises. We document that market response
is more favorable when news announcements are made early in the earnings season (timing
effect). Price reactions on earnings announcement dates and price movements in the following
60 trading days are significantly stronger (weaker) for positive (negative) earnings surprises
announced at the beginning of the earnings season. We explore two sources of the timing
effect: information transfer and firms strategic timing of news announcements. The timing
effect associated with positive earnings surprises is consistent with information transfer in
that late good news announcements are accompanied by significant pre-announcement price
increase. The timing effect associated with negative earnings surprises is mainly driven by
firms strategic delay of bad news announcements since the timing effect does not exist among
bad news announcements that are made earlier than expected.

I. Introduction
To assist market efficiency, the Securities and Exchange Commission (SEC) requires that com-
panies file their quarterly earnings reports in a timely manner following the end of fiscal
quarter.1 As a result, earnings announcements are clustered in time. On one hand, since earn-
ings announcements are mandatory and their report dates are predictable to a large extent,
market response to earnings surprises should be independent of when the news announcement
is made in the earnings season.2 On the other hand, the unique information environment of
the earnings season implies that market reactions to earnings surprises are correlated with the
timing of news announcement. As the earnings season proceeds, market participants infor-
mation sets grow and information searching activity intensifies. Both of them complicate the
price discovery process at the beginning and the end of the earnings season. In this paper, we
investigate whether the relative timing of earnings announcements impacts market response to
earnings surprises and we explore what is the source of the impact.
Using a sample of quarterly earnings announcements between year 1985 and 2003, we docu-
ment that the timing of earnings announcements affects market responses to earnings surprises.
Announcements made early in the earnings season receive more favorable feedback than late
announcements.3 To illustrate, stocks with extreme positive earnings surprises released in
the first 10 days of the earnings season gain 3.10% over a three-day window surrounding the
earnings announcement date. The price of these stocks increases by additional 2.90% in the
1For example, companies are required to file their quarterly earnings report within 45 days after the fiscal
quarter end. Effective on Nov.15, 2002, the filing deadline for filing quarterly earnings reports are being reducedfrom 45 days to 35 days over three years, whereas the deadline for filing annual reports are being reducedgradually from 90 days to 60 days.
2Consistent with conventional wisdom, we define earnings season as the window of one month after fiscalquarter end in which a majority of corporate earnings are released to public.
3In this paper, we define early and late announcement based on the chronicle order of earnings disclosures inearnings season. In comparison, we define advanced and delayed announcement based on the reporting patternof individual firms. An announcement is advanced (delayed) if its report date is earlier (later) than the expecteddate. See subsection B in section V for more details.

following 60 trading days. In total, these stocks appreciate by 6%. In comparison, stocks with
extreme positive earnings surprises disclosed in the last ten days of the earnings season appre-
ciate only 2.87% (1.93% on earnings announcement date and 0.94% in the following 60 trading
days). For negative earnings surprise announcements, the market response is less negative if
the news announcement is released at the beginning of the earnings season. For example, the
average value depreciation is -3.55% (-2.44% on announcement date and -1.11% in the follow-
ing quarter) for announcements made in the first ten days of the earnings season. The value
depreciation is much stronger for announcements released in the last ten days of the earnings
season: a total price decline of -6.50% with -2.38% on earnings announcement date and -4.12%
in the following quarter.
We further explore two possible sources of the timing effect: information transfer and
firms strategic timing of news announcements. Information transfer occurs when market
participants update their beliefs of a firms profitability by extrapolating other firms earnings
reports. Earnings information transfer occurs within the same industry (Foster (1981), Han
and Wild (1990)) and across industries since a firms earnings announcement not only contains
information about its own cash flows but also contains implications for the profitability of
its competitors, suppliers and clients. In the earnings season, massive corporate earnings
reports stimulate investors information searching activity, which in turn stimulates information
transfer. Consequently, the information content of non-released earnings reports has been
supplied by other channels before the public announcement is made. Because of information
transfer, the market response to late news announcements is weaker than for it is for early
announcements.
The timing effect could also be attributed to firms strategic timing of their bad news
announcements. Studies (Kross (1981), Givoly and Palmon (1982), Chambers and Penman
2
8/4/2019 Timing Effect
5/32
(1984), Kross and Schroeder (1984), and Begley and Fischer (1998)) have shown that compa-
nies strategically time their public news announcements to optimize the post-announcement
stock price. These studies provide empirical evidence that good news is announced relatively
earlier than bad news. Delayed announcements more often contain bad news. Consequently,
market participants react less favorably to delayed announcements. Given the fact that pos-
itive (negative) earnings surprises concentrate at the beginning (end) of earnings season and
early (late) announcements tend to be advanced (delayed) from their typical announcement
dates, the timing effect could be driven by the penalty on delayed bad news announcements.
If the timing effect is due to firms strategic timing of bad news announcements, the timing
effect should be the most pronounced among delayed bad news announcements.
Our tests show that the timing effect associated with positive earnings surprise announce-
ments is consistent with information transfer. Price reaction and price drift are weaker toward
the end of the earnings season. The average price reaction to positive earnings surprises an-
nounced at the beginning of the earnings season is 3.10%, which is significantly stronger than
the price reaction of 1.93% associated with announcements made at the end of the earnings
season. Information transfer is reflected by the significant abnormal price increase before the
public announcement. The size-adjusted cumulative abnormal return of late announcing firms
is 0.52% in the first 10 days and 1.22% in the middle 10 days of the earnings season. The sig-
nificant pre-announcement price increase suggests that part of the positive earnings news has
been extrapolated from other information channels and thus been incorporated into the stock
price. Consequently, the price drift after the earnings announcement is much weaker if the
announcement is made at the end of the earnings season. The pre-announcement t price ad-
justment also applies to negative news announcements. For stocks with negative news released
in the last ten days of the earnings season, the average price decline is a significant -1.30% over
3
8/4/2019 Timing Effect
6/32
the first 20 days of the earnings season. However, these late bad news announcements are also
accompanied by strong negative price drifts after the announcement date, indicating that the
timing effect is not purely driven by information transfer.
Our further investigation indicates that firms strategic delay of bad news announcement
significantly contributes to the timing effect associated with negative earnings surprise an-
nouncements. First, we study the reporting pattern of individual firms and find that only 62
percent of bad news announcements are released on time. While firms show little intention
to advance or delay good news announcements, they tend to delay bad news announcements.
Twenty-five percent negative earnings surprises are announced after the expected announce-
ment date, whereas only twelve percent are disclosed earlier than expected. The proportion of
delayed announcements increases from 7.6% at the beginning of the earnings season to 37.21%
toward the end of the earnings season. As expected, the timing effect is the most pronounced
among delayed bad news announcements. Both price reaction (-2.96%) and price drift (-5.16%)
are significantly more negative than for advanced or on-time bad news announcements. In ad-
dition, the timing effect does not exist among advanced bad news announcements. The price
reaction and price drift of these stocks do not vary with the timing of the news announcements.
Moreover, these stocks do not significantly underperform their size decile benchmarks in the
following quarter.
Our paper is the first to link the market response to earnings news with the relative tim-
ing of earnings announcements in the earnings season. It provides evidence that helps better
understand how news about fundamentals is incorporated into stock prices and how clus-
tered corporate events affect the price formation process. For example, the divergent post-
announcement price movements indicate that the post-announcement price formation process
could be motivated by other events other than solely by a firms own earnings news. Therefore,
4
8/4/2019 Timing Effect
7/32
post-earnings announcement drift may reflect price adjustment to other firms earnings news,
which implies that the widely accepted underreaction explanation is overly simplistic.
Our results have applicability to policy makers and market participants. Policy makers are
promoting timely disclosure for market efficiency purposes since there could be incentives and
frictions in the reporting process that distort the price discovery process. Evidence documented
in this paper justifies policy makers promotion of timely information disclosure. Market
participants are interested in our results because the relationship between the timing of news
announcement and the subsequent price movement will affect their information gathering and
trading activities.
The remainder of the paper is organized as follows. Section II describes our research sample
and variable measurements. Section III presents the evidence on the timing effect. Discussions
on the sources of the timing effect are present in section IV and V. Conclusions are drawn in
section VI.
II. Sample Description and Variable Measurement
Our research sample includes stocks listed on the New York Stock Exchange (NYSE), American
Stock Exchange (AMEX), and National Association of Securities Dealers Automated Quotation
system (NASDAQ). We exclude real estate investment trusts (REITs), American Depository
Receipts (ADRs), and closed-end mutual funds from our sample. To mitigate microstructure
effects, we also exclude stocks priced below $5.
We obtain actual earnings and financial analyst earnings forecasts from the Institutional
Brokerage Estimate System (I/B/E/S) raw unadjusted earnings dataset (provided upon re-
quest). The standard I/B/E/S dataset reports the actual and forecasted earnings-per-share
(EPS) that are adjusted for stock splits (i.e. EPS is based on the number of shares outstand-
5
8/4/2019 Timing Effect
8/32
ing as of today along with a split factor). After making retroactive and cumulative stock split
adjustments, estimated and actual EPS are rounded to the nearest cent. The problem with
this practice is that comparisons of actual with forecast EPS for firms that have executed
stock splits are less precise. Consequently, there is a disproportionate number of firms that
exactly meet expectations when in fact they miss or beat expectations.4 Had we utilized the
commonly used I/B/E/S standard files, we would have missed a lot of earnings surprises.
We obtain data on stock returns and other financial information from CRSP/COMPUSTAT
merged quarterly files and the prices-dividends-earnings files. To ensure that fiscal quarters
are aligned, our sample is restricted to firms with March, June, September and December fiscal
quarter end. By doing so, we drop roughly 15% observations. The sample period runs from
1985 through 2003 because of the constraints of I/B/E/S data.5
We measure earnings surprise by analyst forecast error (AFE). AFE is defined as the dif-
ference between the actual EPS for quarter q and the most recent mean consensus analyst
forecast for quarter q. The difference is scaled by the book value per share at the end of
quarter q-1.6
We use analyst consensus forecasts as a benchmark because financial analysts
are believed to be the most important information intermediaries between firms and investors.
They routinely collect and process information from various channels and disseminate informa-
tion to the market. Academic studies in accounting and finance have increasingly used analyst
forecast as a proxy for market expectation. Empirical studies have shown that financial ana-
lysts help interpret new information. Stock prices react more strongly to earnings that are not
4
For example, Dell delivered an earnings per share (EPS) of $1.36 in 1994, which beat analysts consensusforecast $0.96 by 40 cents. According to the standard-issue I/B/E/S, however, Dell met analysts expectationswith an EPS of $0.02. The much smaller EPS is due to an adjustment factor of 64 for Dell in 1994 in theAdjustment File of I/B/E/S.
5I/B/E/S starts reporting analyst quarterly earnings forecast in 1984. As a result, few observations areavailable for 1984.
6Results using median analyst forecast are not tabulated but have similar pattern. In fact, the median andmean forecasts are similar, with a correlation coefficient of 0.998. Untabulted results with lagged price as thescalar are similar to those reported.
6

predicted by financial analysts. In addition, AFE does not require a particular model design
for the earnings generating process.
To ensure the robustness of our results, we use another earnings surprise measure that is
derived from the individual financial analyst earnings forecast. The consensus earnings forecast
is computed every month. As a result, the monthly consensus may not reflect the most recent
information. Furthermore, if some analysts do not update their forecasts frequently, their
forecasts become stale but are still used in the computation of consensus forecasts. Using the
most recent individual analyst forecast circumvents the above two problems. The earnings
surprise measure based on individual analyst forecast is calculated similarly to the one based
on the consensus forecast.
The market response to an earnings surprise is measured by price reaction (CAR3) and
price drift. Price reaction reflects the immediate price change surrounding the earnings an-
nouncement date. We estimate CAR3 by the sum of daily abnormal returns over the window of
[-1, 0, 1], where 0 represents the earnings announcement date from I/B/E/S. Daily abnormal
return for firm j on day i is calculated as the difference between the raw daily return of firm
j and the value weighted average returns for NYSE, AMEX and NASDAQ firms in the same
size decile based on NYSE breakpoint at the end of the previous year. Including day -1 and 1
is motivated by fact that COMPUSTAT receives reported earnings data from various sources,
including newswire, newspapers, and brokers. Since newswire services run beyond the close
of trading, announcements appearing during that time interval are dated to the subsequent
trading day. As a result, information may have been impounded into security prices on day -1
or 0 for announcements whose announcement date is from the news media, and on day 0 or 1
when announcement date is from newswire services.
Price drift reflects the price movement in the following quarter after the earnings announce-
7

10/32
ment date. Following existing studies, we estimate price drift over a window of sixty trading
days. Specifically, we calculate the holding period return (HPR) of a stock over the interval
of [2, 61]. We also calculate the HPR of its size benchmark portfolio over the same holding
period. Price drift is defined as the difference between a stocks HPR and the HPR of its re-
spective size benchmark portfolio. When calculating the sixty trading day cumulative return,
we make sure that we do not include stock returns during the next earnings announcement
period. For a small number of observations, the next earnings announcement date falls into
the sixty trading day period, we stop the calculation of price drift one day before the next
earnings announcement date.
III. Timing of Earnings Announcements and Market Responses
to Earnings Surprises
A. Distribution of Quarterly Earnings Announcements
The SEC explicitly requires that quarterly earnings reports be filed within 45 days following
the end of fiscal quarter. As a result, earnings announcements are clustered in time. Table I
details the distribution of quarterly earnings announcements between 1985 and 2003.
The distribution pattern based on overall quarterly earnings announcements shows that
only 8.13 percent of announcements are made in the first 15 calendar days after the fiscal
quarter end. Within 45 calendar days after the fiscal quarter end, 90.02 percent of firms
announce their quarterly earnings performance. On average, 81.90 percent of announcements
are made in the earnings season, the time period in which a majority of corporate earnings
are released to the public.7 In addition, half of the announcements made in the earnings
7In this paper, we define earnings season as a window starting from day16 of the first calendar month afterfiscal quarter end and ending on day15 of the second calendar month after fiscal quarter end. Our definition isbased on the conventional wisdom and the distribution of earnings announcements in 5-day intervals after fiscalquarter end (untabluated).
8

11/32
season concentrate in the first ten days. Only 9.98 percent of earnings announcements are
made beyond the earnings season (among which only 3.85% are made beyond 2 months after
the fiscal quarter end).
Table I also presents the distribution pattern of earnings announcements with extreme earn-
ings surprises. At the end of calendar quarter q, we rank all quarterly earnings announcements
released in quarter q into quintiles based on the magnitude of earnings surprises. Extreme
positive (negative) earnings surprises are those ranked top (bottom) 20 percent. Despite the
extreme magnitude of earnings surprises, a majority of those announcements are still made
in the earnings season. The proportion of in-season announcements is 75.86% for extreme
negative earnings surprises and 82.67% for extreme positive earnings surprises. However, the
proportion of negative news reports released after the earnings season significantly outnumbers
that of positive news reports. 19.31 percent extreme negative earnings reports are disclosed
after the earnings season, while it is only 10.36% for reports with extreme positive earnings
surprises.
Within the earnings season, there is no apparent concentration of negative news announce-
ments in a particular time period. Bad news reports are evenly distributed over the earnings
announcement month with 27.76% in the first 10 days and 21.08% in the last 10 days. In com-
parison, extreme positive news announcements tend to cluster at the beginning of the earnings
season. 40.33% of good news reports are released in the first 10 days, compared with only
14.41% in the last ten days.
B. Evidence on the Timing Effect
In this section, we investigate whether the timing of earnings announcements affects the market
response to earnings surprises. Market response is measured by the immediate price reaction
9
8/4/2019 Timing Effect
12/32
surrounding the earnings announcement date and price drift in the following quarter. Table
II summarizes the evidence based on earning surprise quintiles. The overall impression is that
market reacts more favorably to the news released early in the earnings season.
For positive earnings surprise announcements, the magnitude of price reaction and price
drift monotonically decreases as the earnings season proceeds. To illustrate, stocks with ex-
treme positive earnings surprises on average gain 3.99 percent over three trading days sur-
rounding the earnings announcement date if the news is released before the earnings season
starts. The value appreciation continues in the following quarter by additional 4.13 percent.
Meanwhile, market reactions to extreme positive earnings surprises disclosed beyond the earn-
ings season are lack of luster. The average immediate price reaction is 1.91 percent, only a half
of what can be achieved if news is announced early in the earnings season. Announcing-late
stocks also outperform their size benchmark portfolios by a much smaller margin in the fol-
lowing quarter. The 60-day size-adjusted cumulative abnormal return is only 1.34% compared
with 3.99% for early announcements. The timing effect is robust throughout the earnings
season. Announcements released in the first 10 days of the earnings season are responded by
3.10% price increase surrounding the earnings announcement date and 2.90% in the following
quarter. Both price reaction and price drift are significantly higher than for announcements
made in the last 10 days of earnings season (average price reaction of 1.93% and price drift of
0.94%).
For negative earnings surprises, price reaction and price drift are less negative if announce-
ments are made early in the earnings season. Firms with bad news reported before earnings
season starts get the least penalty. Average price decrease on announcement date is -1.76 per-
cent, the weakest compared with price reaction to bad news announced in the earnings season.
Moreover, these stocks do not underperform their size companion portfolios in the following
10
8/4/2019 Timing Effect
13/32
quarter. The cumulative abnormal return over sixty trading days is 0.39 percent, indicating
there is no further price decline after the earnings announcement date. In contrast, market re-
acts strongly to bad news disclosed late in the earnings season. For example, extreme negative
surprises released in the last 10 days of the earnings season are accompanied by a total value
deprecation of 6.40% (-2.38% surrounding the announcement date and -4.12% in the following
quarter), which is more than twice the value depreciation (-3.55%) for early announcements.
The differential market response to news of the same magnitude but occurs at different
time in the earnings season implies that the timing of announcements affects price discovery
process. In the following sections, we explore two sources of the timing effect: information
transfer and firms strategic timing of news announcements.
IV. Information Transfer and the Timing Effect
Studies such as Foster (1981), Han and Wild (1990) have shown that earnings information
transfers within the same industry, i.e. stock prices of competing firms react to earnings an-
nouncements made by other firms in the same industry. The price comovement arises because
firms in the same industry have similar cash flow characteristics. A firms earnings announce-
ment not only discloses firm specific cash flow information, but also contains information about
the common elements that affect the profitability of all firms in the same industry. Earnings
information also transfers across industries. Because the earnings reports of a firms suppli-
ers and clients also shed light on the business growth potentials of a firm. These alternative
information channels help alter investors beliefs of a firms profitability and induces price
changes.
In the earnings season, massive corporate earnings reports not only broaden information
transfer channels, but also stimulate market participants information searching activities. At
11
8/4/2019 Timing Effect
14/32
the beginning of the earnings season, the lack of massive earnings news to set a distinctive
tone to trade in equity market causes investors to wait and hold their interests. As more
earnings news hits the market, the buying and selling interests grow. As investors and financial
analysts intensify their information searching and processing, the surprise component in non-
released earnings reports becomes smaller. Consequently, information transfer causes pre-
announcement price adjustment, weaker price reaction and weaker price drift for earnings
surprises released late in the earnings season.
To test the contribution of information transfer to the timing effect, we track stocks abnor-
mal price changes in the earnings season. We divide the earnings season into three subperiods
BGN, Middle, and END, with BGN and END refer to the first and last ten calen-
dar days of the earnings season. We calculate the cumulative abnormal returns over each time
interval as the difference between the holding period return (HPR) of an individual stock and
the HPR of its size decile benchmark portfolio.8 Table III summarizes the results based on
extreme earnings surprise announcements made in the first and last ten days of the earnings
season.
The timing effect associated with positive earnings surprise announcements is consistent
with information transfer. The price reaction to news released late in the earnings season is
1.17% smaller than for early announcements. However, before the public disclosure, the size-
adjusted price of late announcing firms has gone up by 1.68% (with 0.52% in the first 10 days
and 1.22% in the following 10 days). The significant pre-announcement price increase indicates
that part of the earnings surprise has been anticipated, and justifies the much smaller price
reaction and price drift for late announcements.
However, the timing effect associated with negative earnings surprise announcements can-
8We obtain the value-weighted daily returns of size deciles from Professor Kenneth R. Frenchs web site.
12
8/4/2019 Timing Effect
15/32
not be attributed to information transfer. For bad news disclosed in the last ten days of the
earnings season, the pre-announcement price decline is -1.30% over the first 20 days of the
earnings season. Despite the significant pre-announcement price decline, the price reaction to
late announcements (-2.38%) is not significantly smaller than that for early announcements
(-2.44%). The insignificant difference between price reactions may be caused by the bad
news travels slowly phenomenon documented by Hong, Lim and Stein (2000). However, bad
news travels slowly cannot explain why late announcements are accompanied by a much
stronger negative price drift of -4.12%. The strong post-announcement price decline for news
announced late in earnings season indicates that the timing effect is not purely driven by
information transfer.
V. Strategic Timing of News Announcements and the Timing
Effect
Corporate managers have become increasingly aware of the potential impact that corporate
disclosure strategies can have on a firms value. An important element of a firms disclo-
sure strategy is the timing of its public news announcements. Through strategic timing, the
management hopes to optimize the post-announcement stock price.
Studies have shown that firms strategically choose the time of the day or the day of the
week to make news announcements. For example, Gennotte and Trueman (1996) demonstrate
that under reasonable conditions, market prices better reflect the valuation implications of an
earnings announcement when it is made during trading hours rather than after the market has
closed. They predict that the average price reaction to news made during trading hours will
be more positive than news disclosed after the market is closed. Their prediction is consistent
with the empirical evidence documented by Patell and Wolfson (1982), Damodaran (1989),
13
8/4/2019 Timing Effect
16/32
and Francis, Pagach and Stephan (1992). At the intra-week level, Vigna and Pollet (2004)
show that firms tend to release bad news on Friday because investors are more distracted
from job-related tasks. The limited attention on Friday will mitigate market reaction to bad
news. Vigna and Pollet find that, despite the smaller market reaction due to distraction on
Friday, the post-Friday price drift is stronger than that for non-Friday announcement. Since
the total value depreciation is indifferent for Friday and non-Friday bad news announcements,
it indicates that the quality of decision-making is not affected by the timing of bad news
announcements.
Besides intra-day and intra-week strategic timing, firms also intentionally advance or delay
news announcements, depending on the nature of the news. Studies in 1980s (Kross (1981),
Givoly and Palmon (1982), Chambers and Penman (1984), and Kross and Schroeder (1984))
document that the announcement delay is negatively related to earnings surprises. Therefore,
delayed announcements are accompanied by more negative or less positive abnormal returns
on earnings announcement dates. These studies show that reward and penalty are robust
after controlling for the sign and magnitude of earnings news. Begley and Fischer (1998)
confirm that the good news early, bad news late phenomenon persists in the new litigation
environment in 1990s, which would discourages the delay of bad news announcements.
There are several reasons why the management have incentives to delay bad news announce-
ments. First, they may be able to complete contract negotiations or security issuance at more
favorable terms without the bad news. Second, the management need extra time to resolve
disagreement with auditors. Third, the management needs more time to prepare response to
criticism or come out with a recovery plan that tones down the negative impact on firms value.
Fourth, longer reporting lag gives the management flexibility to decide whether to reverse the
poor earnings performance through complicated accounting practice such as accruals manage-
14
8/4/2019 Timing Effect
17/32
ment. Last, announcing late in the earnings season allows investors to anticipate the bad news
so that the impact on the post-announcement stock price is mitigated. It is not common for
firms to advance good news announcements. However, firms sometimes advance their good
news announcements before the industry leader weighs in with strong earnings performance
that steals their own thunder.
Strategic timing implies that market response to delayed earnings announcements is less
favorable than for advanced or on-time announcements. If announcements released at the end
of the earnings season are dominated by delayed ones, the timing effect may be attributed
to firms strategic delay of bad news. In the following subsections, we first investigate the
reporting pattern of individual firms. We then check whether the timing effect is the strongest
among delayed announcements.
A. Reporting Pattern of Individual Firms
The distribution of quarterly earnings announcements in Table I indicates that positive earnings
reports concentrate at the beginning of earnings season while negative earnings reports cluster
at the end of the earnings season. Does the concentration signal firms strategic timing?
We examine whether the reporting pattern of individual firms is stable over time. Empirical
analysis is done on firms with records of quarterly earnings performance for at least three
consecutive fiscal years. The evidence is presented in Table IV.
We calculate the reporting lag (RepLag) for each firm-quarter observation to see how much
time it takes a firm to release its quarterly earnings report. RepLag is defined as number of
days between the fiscal quarter end and the day prior to the earnings announcement date.
The cross-sectional mean of the within-firm measures indicate that firms on average spend one
month (26-32 days) on earnings report preparation. The report for the 4th fiscal quarter takes
15
8/4/2019 Timing Effect
18/32
a slightly longer time since firms tend to release the annual result together with the 4th fiscal
quarter result. The mean within-firm standard deviation of reporting lag is about 5 days,
which is relatively small considering that weekends and holidays will naturally introduce some
variation.
The stability of a firms reporting pattern is reflected in the announcement delay (DEL).
In the same manner as in earlier studies (e.g. Begley and Fischer (1998)), we define DEL for
firm i in quarter q and year t as
DELi,q,t = RepLagi,q,t RepLagi,q,t1
The mean and median DEL are negative but not significantly different from zero, representing
little time trend of reporting lags for individual firms. The mean absolute deviations from
the previous year (Mean |DEL|) are of the same magnitude (4-5 days) as the mean standard
deviations from the mean reporting lag. It shows that the within-firm variation of reporting
lags over time is mainly due to swings in successive reports for the same fiscal quarter. In a
nutshell, evidence in Table IV suggests a relatively regular and predictable reporting behavior
by individual companies. However, firms do have some flexibility on when to release their
quarterly earnings reports.
Based on the reporting pattern of individual firms, we define that an earnings announcement
is on time if its DEL satisfies -5DEL5. An announcement is defined as being advanced
(delayed) if its DEL is less (more) than 5.
B. Strategic Timing of News Announcements and the Timing Effect
In this subsection, we investigate whether the timing effect is a surrogate of reward on advanced
announcements or penalty on delayed announcements. Our analysis focuses on announcements
with extreme earnings surprises.
16
8/4/2019 Timing Effect
19/32
Table V highlights the average announcement delay (DEL) of announcements made before
the earnings season starts, in the earnings season, and after the earnings season. Announce-
ments released at the beginning of the earning season on average are made earlier than the
same quarter last year. These early announcements on average are advanced by 2 to 4 days
relative to the same quarter last year. Announcements made in the last ten days of the earn-
ings season are on average delayed. The delay is more severe for bad news announcements.
For instance, bad news announcements made in the last ten days of the earnings season are
delayed by 3 days, compared with less than 1 day for good news announcements.
Table V also presents the distribution and proportion of advanced and delayed news an-
nouncements. There is little evidence that firms intentionally advance good news announce-
ments. For extreme positive earnings surprises, 70.14% are disclosed on time. The proportion
of advanced announcements, although slightly higher, is not significantly different from that
for delayed announcements (16.65% versus 13.21%). Advanced good news announcements are
spread evenly throughout the earnings season. Among the good news announcements made
in the first ten days of the earnings season, 15.64% are advanced, which is not significantly
higher than the proportion of 14.40% for advanced announcements made in the last ten days
of the earnings season.
However, firms show a strong intention to postpone their bad news announcements. The
proportion of delayed announcements is more than doubled compared with advanced announce-
ments (25.25% versus 12.33%). Delayed announcements are clustered in the last ten days of the
earnings season and beyond the earnings season. For example, 37.21% of the announcements
made in the last ten days of the earnings season are delayed, which is almost 5 times of the
proportion for delayed announcements made early in earnings season. Despite the tendency
of delaying bad news announcements, 62.43% of bad news announcements are still on time,

which confirms the relatively stable reporting pattern by individual firms.
Table VII reports evidence on the contribution of strategic delay of bad news announce-
ments to the timing effect associated with extreme negative earnings surprise announcements.
Consistent with the prediction of strategic timing, the timing effect is the most pronounced
among delayed bad news announcements. The price reaction to delayed announcements made
at the end of the earnings season (-2.96%) is significantly more negative than for advanced
(-1.60%) or on-time announcements (-2.18%) released in the same time period. Delayed an-
nouncements are also accompanied by the most negative price drift (-5.16%), which is 4 times
of the price drift for advanced announcements and doubles the one for on-time announcements.
The timing effect does not exist in advanced bad news announcements in that price reaction
does not vary with the timing of advanced announcements. Moreover, firms announcing bad
news earlier than expected do not significantly underperform their size benchmark portfolios
after earnings announcement date. In summary, the timing effect associated with extreme
negative earnings announcements is mainly driven by firms strategic delay of their bad news
announcements. The contribution of strategic delay of bad news announcements is robust to
the definition of advanced or delayed announcements.9
VI. Conclusions
In this paper, we study the relationship between the timing of earnings announcements and
the market response to earnings surprises on earnings announcement dates and in the following
60 trading days. We find that announcements made at the beginning of the earnings season
receive more favorable feedback (timing effect). Positive earnings surprises reported early in
the earnings season are accompanied by larger price increases on and after earnings announce-
9We run robustness checks by defining on time as -3DEL3, or -1DEL1. Results are similar to thereported ones.

ment dates than late announcements. Early announcements of negative earnings surprises are
associated with the smallest value depreciations.
We explore the contribution of information transfer and firms strategic timing of news
announcements to the timing effect. The timing effect associated with positive earnings an-
nouncements is consistent with information transfer. The price of late announcing firms has
significantly increased before the public news announcement. The pre-announcement price
increase indicates that the information content of late announcements has been extrapolated
from other information channels, such as earnings reports of firms in related industries and
financial analysts research reports. As a result, the price reaction and price drift are both
weaker for late announcements.
The timing effect associated with extreme negative earnings announcements is consistent
with firms strategic delay of bad news announcements. We study the distribution and pro-
portion of advanced and delayed announcements in the earnings season. We find that firms
have little intention to advance news announcements. Advanced news announcements are dis-
tributed evenly in earnings season. However, firms tend to delay the news announcements that
deliver bad news to the market. The proportion of delayed announcements increases toward the
end of the earnings season. As predicted, the timing effect does not exist among advanced bad
news announcements. And the timing effect is the strongest among delayed announcements.
In this paper, we have identified two sources of the timing effect. However, we cannot rule
out the possibility that other factors also contribute to the timing effect. For instance, the
time a firm spends on its earnings report preparation determines the timing of announcement
in the earnings season. Therefore, the timing effect could be a proxy for firm characteristics
that affects a firms report preparation. We also cannot rule out the possibility that the timing
effect is due to investors irrationality. Investors may take announcing late in the earnings
19

season as a signal of poor earnings quality because it allows management to evaluate whether
to do earnings management and how much the earnings management should be. The timing
effect may reflect the cost of that flexibility. The impact of investors irrationality and firm
characteristics such as investor base, litigation risk, proprietary cost, accounting complexity
and the nature of earnings news deserve further explorations.

Table II: Price Reactions and Price Drifts associated withEarnings Surprises Released at Different Time in Earnings Season
This table presents evidence of the impact of announcement timing on the price discover process.At the end of each calendar quarter, earnings surprises (measured by analyst forecast error (AFE))released in the quarter are ranked into quintile. Extreme positive (negative) earnings surprises arethose ranked top (bottom) 20 percent. Price reaction is measured by the cumulative abnormal returnover a window of three trading days [-1, 1]. Price drift is measured by the difference between theholding period return (HPR) of individual stock and the HPR of its size decile benchmark portfolioover a window of 60 trading days [2, 61], where 0 is the earnings announcement date from I/B/E/S.

Table IV: Quarterly Earnings Reporting Pattern of Individual Firms
This table reports evidence on the reporting pattern of individual firms. Reporting lag (RepLag) isdefined as the number of days between the fiscal quarter end and the day prior to the actual earningsannouncement date. Announcement Delay (DEL) is the difference between the RepLag for thecurrent quarter and the RepLag for the same quarter in the previous year. A negative (positive)DEL indicates that earnings report is advanced (delayed). Mean DEL (Median DEL) is thecross-sectional mean (median) of the within-firm measures. The quartile statistics of the absolutevalue of DEL is also reported.
