At Seasonal Odds we examined the Valentines week return of selected marquee Valentines Day stocks over the last 5 years, covering the traditional areas of chocolate, diamonds and jewelry, and flowers.
 
All of these stocks disappoint, on average, over the week following Valentines Day, with card-maker American Greetings, flower delivery service 1-800 Flowers, and Zale, a jeweler, down 60% of the time.
