Even in an era of widespread electronic trading, markets and those who tend to them are still proving vulnerable to the fury of a major hurricane.
Stock markets in the United States will be closed again on Tuesday for a second day without trading as Hurricane Sandy's approach intensified the wind and rain in the New York area.
The New York Stock Exchange, the Nasdaq stock market and BATS Global Markets said in separate statements that they had agreed to close, after consulting with other exchanges and clients. The N.Y.S.E. added that it planned to operate on Wednesday, pending developments in weather conditions.
