The Securities and Exchange Commission announced new measures on Tuesday aimed at avoiding a repeat of the market swoon earlier this month, saying that it would propose that trading in any given stock would be paused if a stock dives more than 10 percent in five minutes.
The rules would apply across all trading venues. The halt in trading would last five minutes.
The proposal, which will be implemented in the next few weeks, is a response to several lessons of May 6, when the Dow Jones industrial average plummeted nearly 1,000 points in a matter of minutes. Existing triggers, or "circuit breakers," that would normally pause trading were outdated and did not go into effect. Meanwhile, different rules governing when to stop trading led to irregularities across the market.
"We continue to believe that the market disruption of May 6 was exacerbated by disparate trading rules and conventions across the exchanges," SEC Chairman Mary L. Schapiro said. "I believe that circuit breakers for individual securities across the exchanges would help to limit significant volatility.
The SEC and the Commodity Futures Trading Commission also released on Tuesday afternoon a report citing six theories on what may have caused the market's sudden gyrations, saying that it was likely that a web of speculative trades linked to the direction of the overall market helped fuel the declines.
The regulators' report sheds little light on which firms, traders and events caused the volatility. But the report underscores how the fate of the stock market today is guided largely by speculators making bets on far-flung exchanges that can nevertheless have a major influence on the prices of blue-chip stocks.
The events of May 6 -- when the price swings of some stocks defied market fundamentals -- dealt a setback to confidence in a financial system already battered by concerns about a worsening debt crisis in Europe. The surge of volatility exposed flaws in the electronic guts of the trading system and highlighted the market's vulnerability to high-speed, computer-driven traders making decisions about what to buy and sell based on mathematical formulas.
A full account of what happened May 6 may take many months to complete, as it did after the spectacular market crash of Oct. 19, 1987, also known as Black Monday. While today's markets are virtually all electronic, making collection of data easier, the amount of data is far larger. In 1987, about 600 million shares were traded on a daily basis. On May 6, 19.5 billion shares were exchanged, comprising 66 million trades.
The SEC is looking at several other practices as it considers reforms.
The agency is contemplating how to reduce the use by market-makers of "stub" quotes. These quotes allow market-makers -- firms that agree to buy and sell shares to ensure that investors can make trades -- to technically stay active in the market as is required by some exchanges.
But the "stub" quotes are usually are far below or above what the market is asking and are almost never executed. On May 6, trades were executed at "stub" prices. Subsequently, exchanges have canceled those trades.
The agency will also look at whether short-term trading strategies, such as those that use computer analysis to make split-second decisions, need to be curtailed, as well as proposals to make it easier to capture and analyze trading patterns across markets.
Grandpa: typical SEC...they do not have a definitive reason for the "swoon" however they are planning on implementing rules to prevent a reoccurring event without a known cause. Grandpa suggests Mary Schapiro spend a bit more time studying the High Frequency Traders (HFT) and their algorithmic formulas.
She will need assistance given the fact that Wall Street employs mathematicians to write the programs. She and the SEC will also need to cease the chummy relationship with their Wall Street cronies and quit buying into the "liquidity" argument presented by the HFT world. At last count, they continue to represent 60-65% of the daily trading volume which is not liquidity, this is the equivalent of gamers trading amongst themselves. Good luck Mary as given the SEC's track record, you will need it and try not to "stub" our toes in the process.
On the topic of speculators Mary, how about tuning in CNBC a couple times a week and witness first hand the constant flow of "bullish" analysts who continue to "spin" data similar to our Government's calculations of Non-farm payrolls, GDP and CPI calculations. This is not my complete list however I do not want to overwhelm you.
If you can stomach it, watch Cramer for an hour and report the value this baffoon brings to the "investing public". I have some old interviews with Mr. Cramer noting his market and stock manipulation while running his hedge fund. Let me know if you are not able to put your hands on a quick copy as I would welcome an opportunity to forward you the link.
One more suggestion: quit hanging out with this guy...he is trouble
