S&P and Dow waver, Nasdaq pares gains as oil prices drop

The S&P 500 and the Dow fluctuated between small gains and losses, while the Nasdaq pared some gains on Thursday, as the impact of strong labor market data was offset by a drop in oil prices. Oil prices fell more than 3 percent, wiping out early gains after the U.S. government reported a weekly crude draw that was within analysts' forecasts, while market optimists expected larger declines.
