Will Another Flash Crash Be Stopped By Stock Market Circuit Breakers?
To avoid another Flash Crash, new circuit breakers for the stock market were suggested by the Securities and Exchange Commission on Tuesday. The new trading curbs would be applied as a trial first to all stocks on the Standard and Poor’s Index. The SEC said the new stock market circuit breakers will pause trading in specific stocks if their prices move by 10 percent or more in five minutes. The trial will begin after a 10-day comment period and will end Dec. 10. The proposal is a response to the unexplained market slide May 6 that drove the Dow Jones industrial average down 700 points within just minutes.

Volatile stocks the focus of NYSE circuit breakers
NYSE circuit breakers that are actually already in place did not trip during the May 6 Flash Crash, but those trading curbs are market-based — they don’t apply at the individual stock level. Reuters reports that regulators have been under intense pressure to figure out what triggered the May 6 meltdown and do something to repair the integrity of U.S. stock markets. The exact cause of the Flash Crash has yet to be determined, but a mechanism to briefly halt trading across markets for a single stock is supposedly solution. A European news service called Reuters adds that the new NYSE circuit breakers are similar to stricter methods used in European markets. The circuit breakers that are at the London Stock Exchange are based on the liquidity and volatility of individual stocks.
Flash Crash exposes stub quotes
The stock market Flash Crash on May 6 brought the market down nearly 1,000 points in a matter of hours. Traders could have looked for cheap payday loans, and the Dow soon rebounded, but it finished the day down 347.80, or 3.2 percent, at 10,520.32. According to the New York Times, some individual stocks suffered quite a bit more than the market at large. For a penny or less per share, five exchange traded funds, mutual funds that trade like stocks, were traded for. There were also nine more trading at 15 cents or less per stock. Stocks traded hands for a penny a share because of what the SEC calls “stub quotes,” or placeholder bids that traders sometimes enter into the electronic system when they don’t really want to buy or sell a stock, but want to stay in the game.
New NYSE circuit breakers will be more equitable
Thousands of trades in hundreds of stocks were canceled as a result of having been judged as “clearly erroneous,” executed by computer before traders were actually able to react to what was happening in the stock market. Market regulators canceled all of the trades that took place between 2:40 and 3 p.m. that were 60 percent or more below the last trade that took place before 2:40 pm. In the same exact article, Reuters says that some investors believe that the circuit breaker on individual stocks is a more equitable approach to prevent drastic, across-the-board trade cancellations.
“The broad market circuit breakers affect everybody, and could penalize people for what could be an index move,” Lou Matrone, a sales trader at JonesTrading, told Reuters. “But the stock-based ones deal with it specifically on a case by case basis. You’re not penalizing people for trading stocks where nothing is really going on, they’re not being dragged in for a ‘fat finger’ problem or some other problem.”
Other trading curbs considered by SEC
During the six-month circuit breaker trial period, the New York Times reports that the SEC will also consider other trading curbs that ended up being discussed during a recent Congressional inquiry into the May 6 disaster. Included were ways to address the risks of market orders, a possible ban on so-called stub quotes of one or a few cents for a stock that is trading significantly higher than that, and the use of trading pauses at various exchanges.
