NYSE Invokes Rule 48 In Effort To Smooth Market Open

The New York Stock Exchange on Tuesday invoked Rule 48, a measure designed to smooth the opening of the market amid potentially volatile conditions. The rule allows the exchange's designated market-makers to refrain from disseminating price indications ahead of the opening bell, making it easier and faster to open stocks on days when trading could be volatile. Stock-index futures point to a sharply lower open for stocks.
