Sticking with retail, another viewer wanted Cramer's take on Whole Foods ( WFM ), a stock that's lost 41% since the start of the year. "I have been very adamant that Whole Foods is not at a bottom yet," Cramer added. "I know a lot of people think that because of the buyback that it's the right time to buy. I like to buy stocks that have positive earnings momentum or growth and Whole Foods doesn't have that right now."
