Shares of Agilent Technologies were among the best performers on the S&P 500 Index (SPX), jumping more than 8.5% following the company's fourth-quarter earnings report. According to Agilent, the firm's earnings rose to $180 million, or 46 cents per share, on a 9% revenue increase to $1.45 billion. The Street was looking for a profit of 52 cents per share on revenue of $1.42 billion.

Investors were rather complacent toward the equity heading into the report, with the stock's Schaeffer's put/call open interest ratio (SOIR) of 0.48 ranking in the 55th percentile of its annual range. Furthermore, Zacks reports 6 buys and 4 hold or worse ratings. This complacency could be blamed for the security's failure to overcome resistance in the 37 region today. This level has held A in check since mid-October, and could pose a problem for the shares going forward.
