    ABSTRACT

    This report evaluates the May 6, 2010 flash crash and details preventative actions that

    should be considered immediately. Further study into the matter targets high frequency

    computerized trading programs as the main culprit. The underlying assumption of my proposal

    is that greater control of market prices can be attained by transferring power from computers to

    humans. Holding this assumption, the report pitches six reforms that should be administered

    immediately. Each proposed reform has been developed to meet specific criteria in that the

    alteration must provide clear benefits that must include enhanced transparency while not hurting

    liquidity.

    The transfer of power from high frequency trading systems to human traders will lead toward

    a shift from unidentifiable back end costs to slightly higher front end costs. Further analysis lead

    toward six major preventative measures that meet the necessary criteria. They are as follows.

    1. Adding a three second pause before trade execution would ban the process of quotestuffing and allow more transparent price quotes for securities.

    2. Installing circuit breaker systems on major and private exchanges would prevent bigdrops in prices by pausing market trades if the price of a security fell more than 10% in a

    15 minute span.

    3. Enforcing a maximum spread less than or equal to 50 basis points will increasetransparency and limit the momentum of price movement in down markets.

    4. Enforcing stricter short-sell rules would limit the incentive for traders to put downwardpressure on prices because they would not be able earn a great profit on the fall of prices.

    5. Cutting taxes for major exchanges that promote non-computerized trading will reduceincentive for exchanges to push computerized trading in which they earn greater profit

    from high volume of trades.

    6. Creating an audit trail for institutional traders might prevent harmful trades by greaterlaw enforcement.

    Intensive research enforces powerful arguments in favor of each reform mentioned in the

    report. Further explanation on the benefits and costs of each reform can be found in the body of

    the report. These reforms should provide necessary measures to prevent events similar to those

    occurring on May 6, 2010. With strict enforcement, markets should experience more favorable

    conditions.

    INTRODUCTION TO THE EVENTS ON MAY 6, 2010

    Earlier this year, a monumental event tested the adhesiveness ofAmericas financial

    engine, Wall Street. The Dow Jones Industrial Average dropped nearly one thousand points

    within a one hour time frame. Hundreds of stocks lost more than sixty percent of their value

    while investors sat powerless on the sidelines. As financial professionals realized they had lost

    control, flight or fight mode took over. Confusion was the only barrier to total chaos. By the end

    of the trading day, the market regained most of its losses while talking heads were already

    starting to lay blame. Investors all over the world sat in high anticipation of the Securities and

    Exchange Commissions actions.

    Exhibit 1

    Five months later, the SEC released a well-crafted report with intent to restore

    confidence. While mainly focusing on causes of the crash, their goal was not accomplished.

    Instead the lengthyreport created more uncertainty among investors, causing the public to lose

    faith in the SEC. Many argued if the SEC would ever strive to prevent an event like this in the

    future. Desperate for reform, congressmen all over the nation started to argue for major changes

    to system. Currently not much has changed to theAmerican financial system. An event similar

    to the May 6, 2010 Flash Crash could occur at any moment.

    Today, action is needed to prevent future technical failures in our markets. Another

    market wide panic can not only slow economic growth but has a high possibility of sending

    America into a depression. By adopting the six reforms mentioned in the body of the report, the

    SEC will be stepping in the right direction, the road leading to a stronger economy.

    CAUSES OF THE FLASH CRASH

    The market setting on the morning of May 6th was filled with worried traders. Investors

    were in panic over the sovereign debt crisis sweeping over Europe that led to deterioration of

    investors previous gains. Because of high uncertainty, institutions were pressuring traders to bepatient while working under strict caution. Intense fear pushed investors to sit on the sidelines

    while traders found their job to be more difficult due to extremely low volume. The market was

    waiting to pounce on the next event, whether good or bad.

    Exhibit 2

    The official report laid blame on a single trading firm, labeling them the spark of the

    crash. The SEC outlined the scenario where a firm in Chicago executed a large directional trade

    based upon an attempt to profit from a market mispricing. The unordinary scale of volume

    tricked automatic computer trading programs to place large sell orders, putting downwardpressure on market prices. The players responsible for filling these trades used automatic trading

    programs as well. Before human traders could do anything, market prices were already at

    bottom. Stocks of corporations such as Proctor and Gamble, Boston Beer and Nordstrom

    dropped to pennies per share before recovering. Realizations that the drop in prices could not

    reflect true value sent the prices back near normal. Because capital markets are interconnected,

    the changes in stock prices cause changes in market prices of non-stock assets. For example, the

    change in the S&P500 index sparked a more volatile exchange rate between the U.S. Dollar and

    the Euro (shown in the Exhibit 3). At the end of the trading day, the SEC released news stating

    they will restore positions on stocks affected by the crash to pre-crash levels.

    Exhibit 3

    After much argument, the financial industry began to accept that high frequency

    computerized trading was the primary reason why the markets lost control. These systems makedecisions based on specific variables faster than humans could realize what has occurred. While

    these programs generated higher profits for firms and lower upfront transaction costs they also

    led to dangerous unidentifiable back end costs. These back end costs, since unidentifiable and

    unexpected are more toxic to markets.

    Exhibit 4

    However measures taken to prevent another technical crash do not need to include a ban

    of high frequency trading systems. Restrictions on how these systems are used offer enoughsafety while greatly saving the benefits. Two hazardous operations done via high frequency

    trading systems are Quote Stuffing and Stub Quoting. Quote stuffing is a common

    procedure by proprietary trading firms that use high frequency trading algorithms to send out a a

    large volume of bids only to retract them immediately after. These bids usually give false

    signals to investors on price direction. For example, if a firm sends out a large amount of buys

    above the market price, investors see that other investors would pay more money for the security.

    Quote stuffing leads to traders devaluing trends in prices. If a trader values these trends, they

    might be able to execute a sell order at a higher price. Stub quoting is a method used by market

    makers, who are parties that provide liquidity to markets for other governmental benefits. A

    market maker is required to provide a quote above and below the market price in that they have

    to fill either a buy or sell order. A stub quote is a place holder quote used by market makers that

    is far from the market price. Their purpose is to fulfill their obligation, while making it unlikely

    to execute the trade. By doing this market makers can bet on the direction of the market o profit

    greater. Many traders do not see this as a negative because a greater profit increases market

    maker competition and reduces transaction costs of trading. On May 6th, lower stub quotes were

    filled before market makers could replace them. This gave momentum to the downward spiral of

    prices. While providing benefit, unregulated use of computerized trading algorithms only creates

    hazardous unidentifiable costs to investors.

    RULES AND REGULATIONS

    Global markets can benefit by stronger regulation of high frequency trading systems and

    electronic exchanges. By transferring power from computers to humans and preventing

    unordinary swings in market prices, markets will become less volatile, safer and more trusted by

    investors. Following, I propose six reforms that clearly hold this assumption. All proposed

    changes meet specific criteria in that the alteration must provide clear benefits that must include

    enhanced transparency while not hurting liquidity.

    Reform #1: Instating a mandatory clearing period of three seconds before trade retraction on

    electronic exchanges.

    One of the major functional reforms the market needs is a restriction on the act of

    quote stuffing. By instating a three second period before allowing bid retraction, high

    frequency operators will not be able to quickly retract their bids, and the trades can be

    executed. The risk posed of possible execution should prevent the majority of quote

    stuffing by firms who operate high frequency trading systems. Three seconds will not do

    any harm to liquidity because the markets will always be three seconds delayed. Having

    a clearing period will also prevent other types of market price manipulation that have to

    do with false trade quotes. Since only electronic exchanges pose a problem, installing

    this clearing service would be a low cost initiative.

    Reform #2: Install and maintain circuit breaker systems on major and private exchanges.

    Circuit breakers on electronic exchanges are necessary in damage control. The breakers

    will stop trading on securities after certain criteria are met. After ten seconds, trading will

  • 8/8/2019 Eng Final Report

    8/14

    8

    resume again but follow the same restrictions. The system is considered an option of last

    resort that wont stop a crash but will minimize damage and create more investor confidence.

    Traders will be able to tell when a circuit breaker is triggered by signs in the market price.

    Different criteria apply to different securities to keep up with natural volatilities.

    1. Stocks priced $25 or less:Breaks if the trades are 10 percent away from the circuitbreaker trigger price.

    2. Stocks priced $25 to $50:Breaks after 5 percent swing from the circuit breaker triggerprice.

    3. Stocks priced $50 or greater: Breaks after 3 percent swing from the circuit breakertrigger price.

    Circuit breakers serve our purpose as a band aid instead of a preventative measure.

    History has shown that we should take advanced precaution no matter upon the

    circumstance.With time certain market conditions might arise where circuit breakers will

    prove of use.T

    he cost to implement is next to nothing and possible side effects are of nosubstance.

    Exhibit 5

    Reform #3: Pose a maximum spread of 50 basis points on market makers Bid-Ask price quotes.

    Aside from quote stuffing, stub quoting is a major hazard of high frequency

    trading systems. Controlling market makers to place quotes within a certain price

    interval will provide buy and sell prices that reflects true market price and therefore

    increase liquidity. While creating more liquidity, markets will become less volatile

    because quotes that are not meant to be filled wont be automatically filled by computers

    and prices will fluctuate naturally. This reform could be done as easy as a signature.

    There were circuit breakers in place during

    the Flash Crash . However these circuit

    breakers were not strict. The chart to the left

    shows the amount of high frequency trades

    that were blocked compared to the trades that

    were executed.

    Since market makers only receive benefits if they accomplish their responsibility they

    will have incentive to follow the regulation. However this regulation will lower profits

    by these liquidity providing firms. By heavily regulating this change, natural and

    effective competition will increase and firms specializing in market making will need to

    innovate to succeed. Over time upfront prices will be as low as before.

    Reform # 4: Ban the act of Short Selling.

    Short selling is the process where an investor sells a security without actually

    owning the security. The investor is given the ability to short sell by brokers allowing the

    investor to borrow the security from another investor, with terms to return the same

    security in the future. Investors profit on short selling by selling the borrowed security at

    a higher price than they return it at. Short selling creates more volatile markets because it

    allows investors to profit quickly on falling prices. By selling securities that would not

    normally be sold, great downward pressure is put on market prices. Short selling gives

    investors great incentive to push market prices downward. This almost always leads to adownward spiral effect when there is a drop in market prices.

    By banning short selling the government would not ban ways to profit on

    downward markets. However to accomplish this feat, the investor would have to execute

    more timely trades that would have much less of an impact on volatility.

    Reform #5: Cut Federal taxes for exchanges that do not allow high frequency trading systems.

    Many experts believe that banning all use of high frequency trading would cause

    great short term damage to the economy. Currently, our economy is not strong enough to

    handle such a drastic change. However, providing incentives to electronic exchanges to

    control the use of high frequency systems can slowly reduce global reliance. Cutting

    federal taxes for exchanges that do not allow, or disapprove use of high frequency

    computerized systems can jumpstart a major trend in the market. Exchanges will have

    enough incentive to begin to promote the shift in power from computers to humans.

    While our economies health does not currently rely on this transition, it can offer

    great benefits in the future. The slow transition would not harm liquidity while it would

    make markets more efficient and transparent. Human traders will be forced to survive by

    developing innovative practices that do not use automated systems. Over time our

    markets will become more efficient and much less risky.

    Reform #6: Impose a mandatory Audit trail for all institutional traders who manage over five

    million U.S. dollars of capital.

    One reason for unorthodox and sometimes unethical market practices is weak

    enforcement by the Securities and Exchange Commission. More stern enforcement will

  • 8/8/2019 Eng Final Report

    10/14

    10

    provide more risk of consequence for unethical and unorthodox behaviors. Since the

    SEC has fixed resources, the most cost effective way to enforce market practices is

    through audits. By implying mandatory auditing for institutional traders, traders are less

    likely to take selfish action that might hurt the markets. Aside from discovering fraud

    and unethical practices, the SEC can use this as a way to further learn how Wall Street

    functions. Auditing institutional activity will also provide more business for accountants

    by expanding the area their service covers. The cost is cheap, the downside is limited and

    the benefits are great.

    CONCLUSION

    Nobel Prize winning economist Paul Krugman once said Greater use of computers has

    propelled the growth of our economy while greater reliance will ignite its downfall . It is now

    clear that the market crash on May 6th, 2010 was caused primarily by reliance on computerized

    trading. Regulation of these computer systems is the best way to control markets to make them

    more efficient.

    The six reforms previously outlined can jumpstart the transition into a better controlled

    market. While each change has individual benefits, together they should create market

    synergies. Theyprovide necessary measures to prevent technical failures so our markets do not

    experience a more devastating Flash Crash. Together, these reforms should create a more

    liquid, transparent and effective market. With strict enforcement, markets should experiencemore favorable conditions.

    The May 6th Flash Crash was a major warning that computerized operations should not be

    relied on. Experts already know, in theory, the science behind the fastest possible computer.

    When humans reach that point, a long lasting depression might be in store. While instantly

    demolishing computerized trading systems would send our economy into frenzy, promoting a

    change away from computer reliance will without doubt benefit global markets. More individual

    power has the potential to evolve the lines of human competition from who can create the

    smarter computer to who can control it.
