Oil prices headed lower today following a bearish inventory report from the Energy Information Administration.

Over the past week oil prices have been moving higher, spurred by strong corporate earnings. Better than expected earnings by several big name companies has led investors to anticipate the economy has been improving.

In the spirit of Valentine's Day, Beth Gaston Moon, an analyst from Schaeffer's Investment Research, reviews a trio of companies that are poised to benefit from the sentiments surrounding the annual lovers' holiday.

Here, she looks at Tiffany & Co. (NYSE:TIF), with its coveted blue boxes; online jewelery retailer, Blue Nile (NASDAQ:NILE); and Limited Brands (NYSE:LTD), with its Victoria's Secret line.

The analyst explains, "The traditional robin-egg blue color of Tiffany & Co. is instantly recognizable, particularly among those with especially generous mates. The luxury retailer has been pointed skyward since early August, tacking on more than 40% and hitting a new 52-week high above the support of its 10-week moving average."

As a contrarian, she adds, "On a sentiment front, TIF could be in the midst of a short-covering rally. Last month, the number of TIF shares sold short dropped 12% as frustrated bears moved toward the exits.

"Nearly 7% of the stock's float remains shorted, however, amounting to a short-interest ratio of about seven days to cover. A continued 'short squeeze' could supply TIF with additional buying momentum. The March 40 call looks like an appealing, though slightly aggressive, play at this juncture."
