The floor of the New York Stock Exchange is empty of traders, Monday, Oct. 29, 2012, in New York. All major U.S. stock and options exchanges will remain closed Monday with Hurricane Sandy nearing landfall on the East Coast. Trading has rarely stopped for weather. A blizzard led to a late start and an early close on Jan. 8, 1996, according to the exchange's parent company, NYSE Euronext. The NYSE shut down on Sept. 27, 1985 for Hurricane Gloria.

Sand bags protect the front of the New York Stock Exchange, Monday, Oct. 29, 2012. Hurricane Sandy continued on its path Monday, forcing the shutdown of mass transit, schools and financial markets, sending coastal residents fleeing, and threatening a dangerous mix of high winds and soaking rain. There had been plans to allow electronic trading to go forward on the New York Stock Exchange but with a storm surge expected to cover parts of lower Manhattan in water, officials decided late Sunday that it was too risky to ask any personnel to staff the exchanges.
