NEW YORK (AP) - U.S. stock markets are closed as Hurricane Sandy nears landfall on the East Coast and are likely to remain closed Tuesday.
The last time the New York Stock Exchange had an unplanned closing since the terrorist attacks of September 2001.
Duncan Niederauer, the chief executive of the exchange's parent company, NYSE Euronext, told CNBC that it was "hard to imagine" that the exchange would open on Tuesday.
A spokesman for the exchange said an official announcement would be made later Monday.
European stock markets were mostly lower. Crude oil fell 32 cents to $85.96 in electronic trading.
U.S. index futures fell slightly in thin trading. Dow Jones industrial average futures fell 61 points to 12,993 and S&P 500 futures fell five points to 1,402. Nasdaq futures fell 15 to 2,643.
