Banks led stocks lower on Thursday as investors fretted a widening foreclosure crisis could undermine the market's strength over the last five weeks.
The S&P 500 has rallied 11.9 percent since September 1 and volume has picked up from anemic levels. But the rally could weaken as an index of bank stocks fell nearly 3 percent on Thursday over growing fears the foreclosure problems could bleed into the broader credit markets and the economy.
"As we all know, the market hates uncertainty and this is a big one. Remember the subprime mess?," said Joe Saluzzi, co-head of trading at Themis Trading in Chatham, New Jersey.
