Sell Coach ( COH), Jim Cramer said Tuesday on CNBC's Stop Trading! segment. Cramer said he was wrong with a call last quarter to buy the accessories retailer in the low $40s. That fact came to light Tuesday morning, when Coach issued cautious year-end guidance, sending its shares plunging 13% in furious trading, to $36 and change. Cramer doesn't like the mortgage insurers either. He'd be selling PMI ( PMI) and MGIC ( MTG) off yesterday's Lehman Bros. downgrade of the sector. "They sliced through book value," Cramer said of the mortgage insurance stocks, which were each off 11% in heavy trading Tuesday after similar declines Friday.
