Stocks fell sharply Tuesday, inflicting the tech-heavy Nasdaq its largest percentage decline in more than six weeks, as a sharp drop in oil prices hurt energy companies' shares and health-care company Johnson & Johnson (JNJ) fell following a report of a possible $24 billion takeover of Guidant Corp. (GDT).

Traders weren't overly concerned by the slide in equities, predicting that if oil continues to decline, buyers will return to Wall Street. In addition, with many professional investors such as mutual fund managers logging gains for the year, there's less threat of a more significant sell-off.

"I am not too concerned right now. I think the character of the market is in place, at least until the end of the year," said Michael Murphy, head trader at Wachovia Securities in Baltimore. "I think there's more of a risk to be out of the market than in the market at this point. And I think it's going to go higher."

The government reported that worker productivity grew at a 1.8 percent annual rate in the third quarter, the slowest pace in nearly two years.
