On October 1, the SEC and CFTC issued a Joint Report on the Market Events of May 6th 2010 which will be presented to the Joint CFTC-SEC Advisory Committee on Emerging Regulatory Issues. The report builds on the preliminary analysis released by the SEC and CFTC staffs on May 18, 2010 and implicates high-frequency trading.
Focusing on the relationship between E-Mini Standard & Poor’s 500 futures and S&P 500 “SPDR” exchange-traded funds, the staffs concluded that a computer-driven sale worth $4.1 billion by a single trader helped trigger the May “flash crash.” The report describes how the “interaction between automated execution programs and algorithmic trading strategies” set off a liquidity crisis and resulted in disorderly U.S. futures and stock markets.
In the past months, the SEC has aggressively pursued ways to respond to the flash crash. Within weeks of May 6th, the SEC proposed establishing a consolidated audit trail of all stock trading (reported in a May 28 Compliance Avenue post). In June, the SEC initiated a program of new trading curbs known as circuit breakers (reported in a June 17 Compliance Avenue post) and in September approved rules expanding the stock-by-stock circuit breaker program.
CFTC Chairman Gary Gensler and SEC Chairman Mary L. Schapiro issued the following statement in connection with the report:
“We appreciate the incredible effort of all the professionals at both agencies who have worked tirelessly, scouring the data, interviewing market participants and reconstructing the events of May 6th. This report identifies what happened and reaffirms the importance of a number of the actions we have taken since that day. We now must consider what other investor-focused measures are needed to ensure that our markets are fair, efficient and resilient, now and for years to come.”
In the wake of the Joint Report, regulators are urging that additional rules be put in place to ensure proper functioning of the U.S. markets.
International Investigations: Last Thursday, there were reports of plans by both Britain and the European Union to investigate high-frequency trading. Reuters reported that Britain has commissioned a UK Treasury study into the practice of high-frequency trading amid concerns that a computer-generated error could affect the economy. Bloomberg reported that the Committee of European Securities Regulators will also investigate high-frequency trading and consider setting up a consolidated tape for the European Union.
