The New York Stock Exchange and Nasdaq will be closed completely Monday and possibly even Tuesday due to the imminent arrival of Hurricane Sandy, its operator said. \"In consultation with other exchanges and market participants, NYSE Euronext (NYX) will close its markets on Monday, October 29, 2012 and pending confirmation on Tuesday, October 30, 2012,\" the operator said in a statement. Earlier, the NYSE planned to suspend only floor operations, but continue electronic trading. \"We support the consensus of the markets and the regulatory community that the dangerous conditions developing as a result of Hurricane Sandy will make it extremely difficult to ensure the safety of our people and communities, and safety must be our first priority,\" NYSE Euronext pointed out, after revising its earlier decision. \"We will work with the industry to determine the next steps in restoring trading as soon as the situation permits,\" it added. The operator of the Nasdaq stock exchange issued a similar statement.
