(Reuters) - Stocks fell for a second straight session on Monday, as Spain appeared closer to needing a national bailout and poor corporate results weighed on the market.

Weak results from McDonald's Corp (MCD.N) added to the cautious tone on Wall Street. Materials stocks were among the day's weakest, hurt by across-the-board declines in commodity prices.

Still, stocks ended well off the day's lows, rebounding from their initial plunge. Stocks appeared to stabilize as the S&P 500 approached its 50-day moving average of 1,332.98, a technical support level that could trigger more losses if convincingly broken.

Overall, three stocks fell for every one that rose on the New York Stock Exchange on Monday, a signal that the afternoon rebound was concentrated among larger-cap shares. On the Nasdaq, about four stocks fell for every one that rose.

"The sell-off this morning was overdone, and obviously, the market felt that way, too," said Eric Green, senior portfolio manager and director of research at Penn Capital Management in Philadelphia, which oversees $6.5 billion.

"Nothing incrementally negative came out, but obviously, we're still worried about the situation there."
