Kroger stock down over 1 percent today, however, after the bell, Kroger reports an unexpected and mysterious spike in potato salad sales and anticipates a significant jump in the share price in after hours trading. In other news, we bought groceries at Kroger today and we were compelled to buy a tub of their potato salad. On a scale of 1-10 we gave it a 5. It was good enough but we have had much better. On the other hand it tasted like a trip to Omaha!
