Ch 10 ‐ Bond Prices and Yields ‐ BKM
Bonds are when a corporation or government borrows money, paying interest in the form of a "coupon,"
and at the end of the prescribed life of the bond, the borrower must pay back the "par value" or "face
value" of the bond. Conveniently, "face value" can be abbreviated as FV, and this corresponds with
the FV part of our calculations below.
Much of this will be basic review, but terms you should know:
FACE VALUE (a.k.a. "PAR")
COUPON RATE
MATURITY DATE
NOTE: These and other optional features are detailed in the contract between the
issuer (company, government, etc) and the holder of the bond which is called an
INDENTURE
YIELDS YIELD TO MATURITY The 'i' on your calculator, also the "discount rate"
YIELD TO CALL The 'i' with 'N' changed to represent time to "call"
... plus you add a "call premium" to the FV
CURRENT YIELD = Coupon Rate / Current Price of the Bond
NOTE that NONE of the yields are specified in the indenture.
BOND TYPES:
ZERO
STRIPS
CALLABLE
CONVERTIBLE
PUTTABLE
FLOATING RATE

BOND PRICING (review)
Using the notation you should understand well by now, a sample bond might look like this:
A 5 year bond, paying a 10% coupon once/yr, priced at $1000 when issued, $1000 face value
The yield (i) is also 10% in this case (it may differ from the coupon, we'll get into this soon).
Remember:
The coupon rate is not the yield, the yield is not the coupon rate. They may be the
same (as this example shows), but the yield is our DISCOUNT rate. The coupon is
what determines how much the bond is paying as a % of face value.

($1,000.00)
What is different here is that the final cash flow is not equal to our previous payments because it includes
the $1000 par value of the bond that is due the bond holder at maturity. An adjustment needs to be made
in how we enter and represent the cash flow components in the problem.
All we need to do is separate CF5 into its two parts:
The face value of the bond can be treated as a lump sum, 1,000.00$
and this is a simple annuity. 100.00$ 100.00$ 100.00$ 100.00$ 100.00$
0 1 2 3 4 5
($1,000.00)
Therefore, the PV of a bond is the PV of its annuity cash flows PLUS the PV of its face value.

Your financial calculator and Excel make this very easy to calculate, but you must make sure you enter the
components of the calculation correctly.
A common mistake here is to enter $1100 for the FV.

More common mistakes to avoid
First, make sure you know the difference between a regular annuity and an annuity due.
See the last page of this section. Know how to toggle between "begin" and "end" mode on
your calculator.
Many bonds will be described as having annual payments (an annual coupon), but most will have
2 or more payments per year.
You need to adjust the
PMT (derived from the Coupon Rate)
RATE or "i"
... and the NUMBER of PERIOD or "N"
It is possible that "i" equals the coupon rate when the bond is issued, but it will rarely be equal to that
value after the bond is issued.
The coupon rate is the percentage of the face value of the bond that is paid out annually.
Therefore, the coupon rate = Payment / Face Value of the bond
e.g. $100 / $1000
10% coupon
But the coupons are frequently paid semi‐annually or possibly quarterly, therefore the annual coupon
rate could be 10%, but when paid semi‐annually, the coupon becomes
$50 per PMT, paid twice per year

YIELD CURVE and the TERM STRUCTURE OF INTEREST RATES
Expectations Hypothesis
Yields to maturity are determined by expectations of future short term rates
These also include expectations about inflation.
FORWARD RATES
If we know a multi‐year bond rate, we can extract a "forward" rate that is inferred
by the multi‐year rate.
If you "know" the 1 year rate of 8%, you can solve for the second rate if you're given
only the two year rate of 8.995% ...

A Regular Annuity vs. an Annuity Due:
A regular annuity has the cash flows structured at the END of the periods. An Annuity Due
has the cash flows at the BEGINNING of the periods. This significantly affects the value of
CFs.
example: N PMT i
5 $100 8%
0 1 2 3 4 5
Reg Ann. 100$ 100$ 100$ 100$ 100$
$399.27 =PV of the regular annuity
Ann. Due 100$ 100$ 100$ 100$ 100$
$431.21 =PV of the annuity due
(use the annuity due or "BEGIN" method on your calculator)
IMPORTANT:
THIS is why you must make sure your calculator doesn't get set to "BEGIN" mode by
accident. The default setting, and the one you'll use almost all the time, is to make your
Time Value of Money (TVM) calculations in "END" mode ‐‐ where the CFs are made or
arrive at the "end" of the periods.
TI BA II +: To toggle between END mode and BGN mode (and back)
2ND ‐ PMT (BGN); 2ND ‐ ENTER (SET); 2ND ‐ CPT (QUIT)
HP 12c: To enter BEG (Begin) mode "g" ‐ 7 ("BEG")
To return to END mode "g" ‐ 8 ("END")
Note that calculators usually only display when you're in "Begin" mode
(the non‐default setting)

PV of a Growing (or "Graduated") Annuity
Starting with our PV formula for annuities, we would like to account for annuities where the CF
grows over time.
1
PVA = PMT1 * [ ( 1 + i )^N ]
i
Doing so is simple, and we need only add growth ("g") to both our discount factor and the denominator.
( 1 + g )
PVGA = PMT1 * [ ( 1 + i ) ]
( i ‐ g )
This is an annuity we valued earlier: a $100 cash flow received for 5 years with an 8% discount rate.
We can discount the individual cash flows using the PV FACTORS. We can use the PV formula in Excel
or the formula above and all return the same PV for the annuity.
Initial
example: N Cash Flow i g
5 $100 8% 3%
PV Factors 0 1 2 3 4 5
PV 8% 1.00 0.926 0.857 0.794 0.735 0.681
No Growth CFs ‐$ $100.00 $100.00 $100.00 $100.00 $100.00
The discounted PMTs ‐$ 92.59$ 85.73$ 79.38$ 73.50$ 68.06$
PVA = 399.27$ (sum of discounted CFs)
$399.27 =PV( 8%, 5, 100)
399.271 = 100 * ( 1 ‐ 1/((1+.08)^5))/.08
The annuity below is identical to the above except we are growing the CF by 3% per year. The same
valuation techniques can apply, but note that Excel and your typical financial calculators do not
allow you to plug in a "g" for the growth rate.
You will need to either individually discount the CFs by the PV factor OR use the PV formula for a
growing annuity.

The discounted PMTs ‐$ 92.59$ 88.31$ 84.22$ 80.32$ 76.60$
PVGA = 422.04$ (sum of discounted CFs)
n/a Excel does not provide a "growth" PV formula

Important:
NOTE that the growth annuity formula is the same as the regular annuity formula but it accounts
for growth. If growth (g) is zero, the annuity has the same value as the "no growth" PV annuity.

INTEREST RATE RISK
Interest Rate Sensitivity
i. Bond prices and yield are inversely related
ii. An increase in YTM results in a smaller Price than an equal decrease in YTMiii. Prices of LT bonds tend to be more sensitive to interest rate changes than ST bonds
iv. Sensitivity of bond prices to yield increases at a declining rate as maturity increases
v. Interest rate risk is inversely related to the bond’s coupon rate.
vi. Price sensitivity is inversely related to current YTM
Change in bond price as a function of change in yield to maturity

D of a Perpetuity = ( 1 + y ) / y
From this we can use an alternate duration calculation in a single formula
assuming this is an annuity , i.e. note the process above can be used for
varying cash flows, for which there are needs and uses (as you'll practice).
Start with the duration of a perpetuity and then adjust for coupon
rate (c), yield (y) and time to maturity (N).

See the Duration Exercise spreadsheet under Course Documents
NOW THAT YOU CAN CALCULATE DURATION, HOW CAN YOU USE IT?
1) The main use is to calculate the change in price movements ...
P / P = -D x [ ( (1+y) / (1+y) ]
D* = D / (1+y) = "Modified" DurationThe modification is the adjustment for yield,
and it allows for an easier to use formula for Δ P
P / P = -D* x [ ( (1+y) ] = -D*y
2) We can also use it to PASSIVELY MANAGE bond portfolios
3) There is another calculation related to duration called CONVEXITY.
Convexity is generally desirable because ΔP is higher when yields fall than when
yields rise
P / P = -D* y + ½ x Convexity x (y)2
-D = [ ( 1 + y ) + N ( c - y) ]

ACTIVE BOND MANAGEMENT
Forecast interest rate movementsIf anticipate declining interest rates – increase portfolio duration, and vice versaGenerate abnormal returns only if information or insight is superior to the rest of the market
CONVEXITY
DURATION creates a linear estimate of the potential price changes.
Actual price change is curved.
18 Managing Bonds 62
The graph below ("Bond Value vs Yield") shows
this across a wide range of prices and yields. In
reality, changes in yield tend to be smaller, and
duration is relatively effective at estimating
price changes due to small changes in yield.
Mispricing error due to convexity is less
noticeable here when we graph a smaller
range for the change in yield based on the
previously used data0

MEASURING / ESTIMATING INTRINSIC VALUE
An investment should be valued as the present value of its expected cash flows.
This is easier to determine for fixed or steady cash flows, but we can apply similar
techniques to value the cash flows of common stock.

VCS = Ʃ CFN / ( 1 + i )N
t=1
Above is the same formula we applied to valuing the PV of an annuity, but the annuity
cash flows are fixed. Here we assume they can vary, but the concept is the same.
We can discount each individual cash flow to current PV dollars, or we can apply some
of the formulas below to the stocks we want to value.
What varies from what we've examined before is:
The timing of the cash flows
For example, do we sell our stock in one year vs. ten years?
Does this make a difference in the present value?
The potential growth of the cash flows
10 Equities 64
First: What is a stock worth today that you expect to hold for only a year or two?
We start with this to emphasize the typical CFs from a stock ‐‐‐
1) the dividends a stock pays
2) the price for which we expect to sell the stock at the end of
our holding period
i = 12% 0 1 2 3 4 5
PV factor 1.000 0.893 0.797 0.712 0.636 0.567
We will discount the CFs below "manually" using the PV factors above
Let's say we have a stock that we expect to be able to sell for 20.00$
in the future. It pays 2.40$ annual dividends at the end of the year.
Note that the price of the stock today has nothing to do with how long we
hold the stock ‐ assuming our dividend yield is equal to our discount rate.

The Dividend Discount Model
The "DDM" uses the dividends as sole source of the cash flows on which we
will base our valuation of the company's stock.
If we assume no growth to the dividends, the stream of cash flows is similar
to a PERPETUITY, and the model we use to value them is the same.
No Growth DDM:
CF D
r i
Constant Growth DDM (often called the "Gordon model"):
CF D0(1+g) D1
r ‐ g i ‐ g i ‐ g
Note the lack of any notation used for the "Div" or dividend in the "No
Growth" model. Because the Dividends in a no growth model, by definition,
do not grow. They do not change. Div0 is equal to Div1, and it's equal to Div3
and Div15 for that matter.
In the Growth DDM, the cash flows, the dividends, are assumed to grow at
the rate equal to "g." Therefore we use "g" to calculate Div1 and this goes
into a the calculation of our value of common stock ‐‐ VCS.
Free Cash Flow Models
Larger, mature companies tend to pay dividends, but many large firms in a
modern economy choose to pay lower or no dividends to fund future growth.
Therefore, models can be used to estimate what a firm could pay out in dividends
FCFE1
k ‐ g
Free Cash Flow to Equity
FCFE = Net Income + Depreciation ‐ Debt Repayments ‐ Capital Exp.

Two‐Stage growth
Many companies, especially younger, fast growing firms, need to be considered
as having not one growth rate, but two (or more).
For this model, we assume a company has a rapid period of growth, and it then
levels off after the company matures and becomes larger.
We refer to these two growth rates merely as:
g 1 : The initial, faster period of growth, e.g. from now to 3
or maybe even 10 years out
g 2 : The second stage of lower, constant growth
The formula for doing this will look complex, but by breaking the stream of
cash flows into two parts, it takes the shape of
1) An annuity of CFs of the growth period "N"
2) The PV of the stream of dividends after the growth
period "N"
Therefore the value of our common stock looks like this:
( 1 + g1 )
D0 (1+g1)* [ ( 1 + i ) ] +
( i ‐ g1 )
( 1 + g1 )
D0 (1+g1)* [ ( 1 + i ) ] +
( i ‐ g1 )
Three‐Stage Growth Model ‐‐
The two‐stage growth model assumes an instantaneous switch from the high
growth rate to the lower rate, e.g. growing at 20% for 5 years and then
suddenly dropping to 5% thereafter.
A three‐stage model assumes a period in the middle where the growth declines
linearly from the high‐growth period to the low‐growth period.
VCS = PVGA + PV0 ( PVGrowthPerp @ N )
1 ‐ ( )^N DN+1
( i ‐ g2 )
( 1 + i )N
( 1 + i )N
1 ‐ ( )^N D0 (1+g1)
N (1+g2)
( i ‐ g2 )
10 Equities 67
This is more realistic and is represented by the equation below:
D0 (N1 + N2)
i ‐ g2 2
You may skip this, but note there are many versions of this model. It is primarily used
to capture a more realistic decline in growth, but some models also capture changing
dividend payout rates.
The Earnings and/or PVGO Model ‐‐
Thus far, we assume a given growth rate (or rates) as given, but we know from
the DuPont deconstruction of ROE that management has significant control
over the firm and how that relates to returns.
First, a firm must invest in future growth. It does not magically appear, and
this growth is a function of two factors: the amount of investment in future
growth, and the ability of management to capitalize on that investment
effectively.
We therefore get our "g" from the retained earnings and our ROE, specifically
it is
g = b * ROE
growth rate = Retention ratio * Return on Equity
For example: If a firm has an ROE of 15%, we would expect it to be able to
grow at a rate of g as follows:
g = b * ROE
Growth
rate
Retention
% ROE %
0.0% 0.0% 15.0%
3.8% 25.0% 15.0%
7.5% 50.0% 15.0%
11.3% 75.0% 15.0%
15.0% 100.0% 15.0%
VCS = * ( ( 1 + g2 ) + * ( g1 ‐ g2) )
10 Equities 68
This should make it clear that if a firm pays out all it's earnings (e.g. EPS) as
dividends (D), then there are no fund to invest in growth, therefore "g" is
zero, and we can value the firm with the same formula we use for a
perpetuity (above) and our No Growth Dividend Discount Model (DDM).
No Growth DDM:
CF D EPS1
r i k
See that we can use "r", "i", and "k" as notation for the same thing
… the required rate of return, the discount rate, the interest rate,
the WACC, etc.
However, if we're going to invest in growth, we won't be paying 100% of our
earnings as dividends, therefore we separate the value of the firm into two
pieces, the value from the expected cash flows, and the value of the growth
opportunities (the PVGO) we create with our new investment using the
retained earnings.
EPS1
k
We solve for the PVGO as
NPV1
k ‐ g
Note that because the valuation models contain various assumptions or rely to varying degrees
on historical data or ratios, the INTRINSIC VALUES they produce can vary significantly.

VCS = = =
RE1 * ( ROE/k ‐ 1 )

PRICE TO EARNINGS RATIOS
‐‐ This will be covered during our discussion of RATIOS in "Company Analysis" (Ch15 ‐ Jones)
P/E ratios can contain a great deal of information about a company, but we
shouldn't draw conclusions that are too broad from this data point alone.
High P/E companies are usually associated with higher growth
Understand the difference between
P/E TTM and P/E Forward
Low P/E firms, therefore are often lower growth, BUT this does not mean
they are low risk.
A LOW P/E could be the result of a high "k" ...
P0 1 ‐ 40%
E1 12% ‐ 6%
= 10.0
Higher risk stocks should have a higher return, therefore the "k" is higher.
P/E
g
A common rule of thumb is that a fairly priced stock will have a P/E ratio close to
its growth rate. This would mean the PEG ratio should be about 1.0 for a fairly
priced stock.
Where the P/E ratio is less than the growth rate OR the PEG < 1.0, the firm may
be a bargain. (Source: Peter Lynch, One Up on Wall Street)
In reality, PEG ratios typically fluctuate between 1.0 and 1.5.
PEG Ratio =

k ‐ g=
10 Equities 70
We can see why higher P/E ratios indicate ample growth opportunities because...
... we can express the forward P/E ratio as
P0 1 PVGO
E1 k E1 / k
And we know that the price of a stock can be expressed as
D1
k‐ g
D1 equals the amount of earnings we are not retaining, or …
D1 = E1 ( 1 ‐ b )
and since growth is a function of ROE and the retained earnings
as g = ROE * b, the latter being the plowback or retention ratio
D1
k‐ g
therefore … P0 ( 1 ‐ b )
E1 k ‐ g
THIS is the P/E ratio for a firm growing a long‐run sustainable pace.
Ex: Price/Share $12 Has a forward P/E of 12.0
EPS $1
The firm's required rate of return 12%
Return on Equity is 15%
The firm pays out earnings at a 40%
Therefore the firm's sustainable P/E ratio would be 13.3

What are the implications of a firm having a sustainable P/E ratio less than
its current P/E ratio?
What about a negative value for a sustainable P/E ratio? What does this
indicate?
Pitfalls of P/E ratios
Earnings are "accounting earnings."
Analysts focus on "earnings quality" at times to account for inflation,
one time charges, etc.
Earnings can be "managed"

Ch 15 ‐ Company Analysis ‐ Jones
Ch 14 ‐ Financial Statement Analysis & Ratios ‐ BKM
This chapter reviews a number of accounting measures and ratios we use in fundamental
analysis. I won't be spending much time reviewing the basics.
It would be worthwhile to review all the ratios covered in this chapter if you are not
very familiar with them. Having the formulas in your notes for the exam would also be
wise.
From the section on Company Stock Valuation, note the discussion RE: P/E ratios and
the PEG ratio. This topic tends to cross into both "chapters" of each text.
In addition to the usual ratios and P/E, we will focus on Return on Equity (ROE), how
managerial decisions can directly affect it, and how the resulting ROE directly affects firm value.
