Stock markets to stay dark Tuesday

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.

Monday’s closure was the first time the New York Stock Exchange had closed because of weather since 1985, when Hurricane Gloria forced trading to halt. The stock exchange’s last unplanned closure came in 2011, following the 9/11 terrorist attacks. The market was closed for four days.

It’s unclear whether stock markets will be open Wednesday.

“We intend to re-open our U.S. markets on Wednesday,” NYSE Euronext said, adding: “conditions permitting.”
