So what would happen if say the floor of the New York Stock Exchange was attacked or even destroyed?
The psychological impact would of course be horrible, but trading would go on. In fact, local investment advisor David Healey says trading floor isnâ€™t even necessary. The NASDAQ exchange doesn't even have a trading floor.
He says many backup systems are in place. â€œThey would shift it to alternative places, anyplace you can get a computer hook-up anymore these days, and you can have a trading floor."
And of course unlike the airlines, you don't have to put yourself at risk to use the stock market. Prices would dip, Healey says, but he doesn't see why there would be a crash.
