Officials announced that new trading curbs, also known as circuit breakers, would be tested during a six-month trial period ending on December 10, 2010. These circuit breakers would halt trading for five minutes on any S&P 500 stock that rises or falls more than 10 percent in a five-minute period.[72][73] The circuit breakers would only be installed to the 404 New York Stock Exchange listed S&P 500 stocks. The first circuit breakers were installed to only 5 of the S&P 500 companies on Friday June 11, to experiment with the circuit breakers. The five stocks were EOG Resources, Genuine Parts, Harley Davidson, Ryder System, and Zimmer Holdings. By Monday June 14, 44 had them. By Tuesday June 15, the number had grown to 223, and by Wednesday June 16, all 404 companies had circuit breakers installed.[74] On June 16, 2010, trading in the Washington Post Company’s shares were halted for five minutes after it became the first stock to trigger the new circuit breakers. Three erroneous NYSE Arca trades were said to have been the cause of the share price jump.[75]

As of September 10, the SEC approved new rules submitted by the national securities exchanges and the Financial Industry Regulatory Authority (FINRA) to expand the circuit breaker program to include all stocks in the Russell 1000 Index and certain exchange-traded funds. The SEC also approved new exchange and FINRA rules that clarify the process for breaking erroneous trades. A list of the securities included in the Russell 1000 Index, which was rebalanced on June 25, is available on the Russell website. The list of exchange-traded products included in the pilot is available on the SEC’s website. The SEC anticipates that the exchanges and FINRA will begin implementing the expanded circuit breaker program early next week. The erroneous trade rules were developed in response to the market disruption of May 6. The rules will make it clearer when — and at what prices — trades will be broken by the exchanges and FINRA. As with the circuit breaker program, these rules will be in effect on a pilot basis through December 10, 2010.

For stocks that are subject to the circuit breaker program, trades will be broken at specified levels depending on the stock price:

For stocks priced $25 or less, trades will be broken if the trades are at least 10 percent away from the circuit breaker trigger price.
For stocks priced between $25 and $50, trades will be broken if they are 5 percent away from the circuit breaker trigger price.
For stocks priced more than $50, the trades will be broken if they are 3 percent away from the circuit breaker trigger price.

Where circuit breakers are not applicable, the exchanges and FINRA will break trades at specified levels for events involving multiple stocks depending on how many stocks are involved:

For events involving between five and 20 stocks, trades will be broken that are at least 10 percent away from the “reference price,” typically the last sale before pricing was disrupted.
For events involving more than 20 stocks, trades will be broken that are at least 30 percent away from the reference price.

On May 6, the markets only broke trades that were more than 60 percent away from the reference price in a process that was not transparent to market participants. A list of ‘winners’ and ‘losers’ created by this arbitrary measure has never been made public. By establishing clear and transparent standards for breaking erroneous trades, the new rules should help provide certainty in advance as to which trades will be broken, and allow market participants to better manage their risks.
