S&P 500

The Dow Jones Industrial Average squeezed out a small gain of 19.66 points to close at 14,567.17, led by Microsoft, while General Electric lagged.

The S&P 500 advanced 7.25 points, or 0.47 percent, to end at 1,562.50. The Nasdaq climbed 27.50 points to finish at 3,233.55. The CBOE Volatility Index (VIX), widely considered the best gauge of fear in the market, declined below 15.

Most key S&P sectors closed in positive territory, led by energy and materials.

"For the short-term we expect the S&P 500 to be range bound between 1,531 and 1,600," wrote Elliot Spar, market strategist at Stifel Nicolaus. "Narrow but lots of opportunities to be on the right or wrong side of many stocks. Many leading and popular names have broken their 50-day moving averages and trend line support. Those are the ones you should avoid buying on dips and should be selling calls against them on bounces to resistance."
