Sears (SHLD) (CSC) Crushed, (PFE) (XOM) (CVX) Fall

Based on low guidance, failure to meet expectations and falling oil prices, Pfizer (NYSE:PFE), Exxon (NYSE:XOM), Chevron (NYSE:CVX), Computer Science (NYSE:CSC) and Sears Holdings (NASDAQ:SHLD) are all down today.

The worst performer of this grouping of stocks is Computer Sciences, which was trading down just below 13 percent on the day. Low guidance of a loss of $1.35 after saying they expected a gain of 14 cents pushed the share price down.

Next was Sears, which was down over 9 percent so far, plunging after it projected a big loss for the fiscal first quarter of the company. Sears had also originally called for a 14 cent gain, adjusting it to a loss of $1.35 to $1.81 a share.

Exxon Mobil and Chevron were both down on the drop in oil prices, both trading down just under 2 percent.

Pfizer is weighing on the Dow, as it is the biggest decliner on the index, falling over 2 percent after the pharmaceutical company beat earnings expectations but reported revenue that fell short of what analysts had been looking for.

Pfizer (NYSE:PFE) was trading at $20.33, down $0.70, or 3.31 percent, as of 1:52 PM EDT.
