Investigation into stock market circles around "circuit breakers"
The major securities exchanges are considering adopting a uniform system of "circuit breakers" to slow trading during rapid market swings, a response to last week's historic stock plunge.
The heads of the biggest exchanges were to discuss the topic Monday at a meeting with federal regulators, according to two people with knowledge of the situation. They spoke on condition of
anonymity because the meeting was ongoing.
In an effort to calm Thursday's market volatility, the New York Stock Exchange invoked a measure to slow trading. Some analysts believe that drove trades onto other electronic exchanges, which
didn't slow trading. That left fewer buyers and sellers to help set prices, potentially worsening the volatility.
