A few days ago, on its anniversary, I reviewed the flash crash of 2006, the impact it had on the investing public along with the “do’s” and “don’ts” when using sell stops.
The WSJ (subscription required) had a follow up story about the resulting proposals for a trading-halt system for stocks and ETFs. Let’s look at some highlights:
The current trading halts, known as circuit breakers, briefly pause trading in shares of certain securities that rise or fall by 10% or more in a five-minute period, guarding against rapid price swings. The system originated in the weeks following the May 6, 2010 “flash crash”–when the Dow Jones Industrial Average plunged nearly 1,000 points before quickly rebounding–and applies to securities in the Standard & Poor’s Composite Index of 500 stocks, the Russell 1000 stock index and 344 exchange-traded funds.
