Limit-down standard:

U.S. securities regulators and stock exchange officials are about to propose a circuit breaker system applicable to all exchanges. In order to suspend or suspend stock trading in the event of significant market fluctuations.

The Dow Jones Industrial Average plunged nearly 1,000 points intraday on May 6. The Dow Jones Industrial Average fell 481 points in 6 minutes that afternoon and rebounded 502 points in the next 10 minutes. The Dow ended the day down 348 points.

The U.S. Securities and Exchange Commission (SEC) will also announce the preliminary results of its investigation into the "flash drop" in U.S. stocks that day. The U.S. Securities and Exchange Commission is considering establishing a unified stock price limit system. The price limit system will have a six-month testing period. Each stock exchange needs to establish and operate a circuit breaker system before June 14, 2010.

Currently, the circuit-breaking policies of various stock exchanges for individual stocks are inconsistent. Critics believe that this inconsistency also contributes to market oscillations. Because if a stock is suspended from trading on one exchange but continues trading on another, this will increase market volatility.

The exchange needs to submit individual stock price limit standards and obtain approval from the U.S. Securities and Exchange Commission before June 14, 2010.
