U.S. stock exchanges delayed the expansion of volatility curbs by two months, according to a notice from Nasdaq OMX Group Inc.
The marketwide system known as limit-up/limit-down, which is meant to prevent mistakes from prompting wide swings in stock prices, won’t be expanded to cover the final 15 minutes of the trading session until Feb. 24, according to Nasdaq. The extension had been planned for Dec. 8.
