The alternative uptick rule (Rule 201) approved today imposes restrictions on short selling only when a stock has triggered a circuit breaker by experiencing a price decline of at least 10 percent in one day. At that point, short selling
would be permitted if the price of the security is above the current national best bid.
Rule 201 includes the following features:
Short Sale-Related Circuit Breaker: The circuit breaker would be triggered for a security any day in which the price declines by 10 percent or more from the prior day's closing price.
Duration of Price Test Restriction: Once the circuit breaker has been triggered, the alternative uptick rule would apply to short sale orders in that security for the remainder of the day as well as the following day.
