Now Is Not the Time to Get Aggressive on Whole Foods Stock, Says Jim Cramer

Jim Cramer says John Mackey, who's returning to Whole Foods Market (WFM) , as the sole CEO, will "do a good job in a challenged market." Walter Robb, who had been co-CEO is now out. Cramer says investors really can't be aggressive on Whole Foods' stock until a turn in the same-store sales numbers. At the same time, he doesn't think there's a lot of risk to owning Whole Foods, other than the fact that it is dead money for now.
