It's official: Stock markets will be closed Tuesday.
The New York Stock Exchange announced it would remain closed another day because of Hurricane Sandy, which is due to slam into the East Coast on Monday evening.
NYSE Euronext, the stock exchange's parent company, said it closed its markets Tuesday "in coordination with all U.S. equities, bonds, options and derivatives markets."
The BATS stock exchange also announced it would remain closed Tuesday.
Hurricane Sandy already closed U.S. stock markets Monday. The New York Stock Exchange closed its trading floor, its iconic Wall Street headquarters barricaded with sandbags as rising waters threatened lower Manhattan.
