CNBC host Jim Cramer advised investors to sell their shares in Clover Health Investments Corp., calling the health insurance company a “two-leaf clover.” What Happened: Cramer, instead, advised investors to buy shares of Minnesota-based healthcare company UnitedHealth Group Inc., saying he does not like Clover Health’s business model. “Why do you want to traffic in Clover? No, thank you. That’s a two-leaf clover,” Cramer said on CNBC’s “Mad Money Lightning Round” on Wednesday.
