Valentine's Day is around the corner, but are love-related stocks a good investment?

Not always, says Brent Wilsey, president of Wilsey Asset Management.

Wilsey is bullish on Build-A-Bear Workshop (BBW - Get Report) ahead of Valentine's Day. Build-A-Bear produces personalized bears for that special someone. And while sales have fallen 5.1% over the last 12 months, Wilsey likes the fact that earnings per share have increased 17.8% during the same time frame, as well as the company's valuation.

"Build-A-Bear Workshop has great valuation ratios as the price/sales is 0.52, which is below the industry average of 0.76 and price/cash flow is 5.24, which is more than half the industry average of 10.72," says Wilsey. "Build-A-Bear has good liquidity as the current ratio is 1.39 and there is no debt on the balance sheet."

And while diamonds are a girl's best friend, Tiffany (TIF - Get Report) shares are not an investor's pal, according to Wilsey. Tiffany pays a dividend of 2.2%, yet uses 47.4% of earnings to pay out the dividend.

Wilsey is also negative on the Hershey Company (HSY - Get Report) due to its valuation.

"Hershey still looks expensive, as the current P/E is 33.4, which is well above the industry average of 26.23," says Wilsey, adding that its total debt/equity of 360.14% is a major negative for the company.

Finally, Wilsey says 1-800-Flowers (FLWS - Get Report) simply won't deliver. In his view, the balance sheet has some "question marks" and looks over leveraged.

"The company has a lot of short-term debt on the balance sheet as total debt/equity is 104.5% and long-term debt/equity is 39.6%," says Wilsey. "Looking out to June 2018 estimates, GAAP EPS of 54 cents gives us a target sell price of $8.91."
