Kenneth Polcari knows, and planned accordingly.
"The exchange is open because the exchange is always open," said Mr. Polcari, who brokers trades on the floor for ICAP. "The exchange doesn't close just because it's snowing outside." Mr. Polcari, who lives in Mount Kisco, N.Y., would normally rise at 4:30 a.m. and catch the 5:15 Metro-North Railroad train to Grand Central Terminal to arrive downtown by about 6 a.m. But as the snow began to pile up, he got on a 6:40 p.m. train Sunday. After grabbing a slice of pizza at Grand Central, he rode the subway to Wall Street and checked into the Club Quarters hotel near the exchange. All the other rooms were taken, he said, filled with financial-services workers who had to be at their posts or desks on Monday.
"People around the world trade on the New York Stock Exchange," Mr. Polcai said. "They don't know and they don't care that it is snowing outside."
