SEC sets unified stock-halt rule for drops of 10%

WASHINGTON (MarketWatch) -- Top regulators and stock-exchange officials on Tuesday proposed the creation of a unified circuit-breaker system for all exchanges to halt or slow down trades of a particular stock if the price moves 10% or more in a five minute period. The proposal, which would be market-wide, comes in the wake of the Dow Jones Industrial Average's sudden drop of nearly 1,000 points on May 6 before swiftly recovering to end with a 348-point loss
