Hurricane Sandy forced Wall Street to close on October 29, the anniversary of the 1929 stock market crash. It was the exchanges' first weather related closing in 27 years. The hurricane and its after effects led to a two day shutdown. Yet despite the destruction wrought by the storm, when US Stock markets re-opened, a relatively normal day unfolded. The Dow Jones Industrial Average and the Nasdaq composite index both fell less than 1%. Meanwhile, the S&P 500 ended on the final trading day of the month, fractionally higher.
