Here's what Jim Cramer had to say about some of the stocks that callers offered up during the "Mad Money Lightning Round" Monday evening:

Kroger (KR Quote): "I'm concerned about the supermarkets. The margins are getting squeezed. I cannot endorse that group."

First Solar (FSLR Quote): "First solar remains the least expensive way to play solar. I want you to stay in it, but I want you to buy more at a lower price."

Imax Corp (IMAX Quote): "I've been wrong on this one. It's been moving, but I still won't recommend this one. "

Sina Corp (SINA Quote): "I have been staying away from China. It's too explosive and too crazy, I don't want to lose people money."

Fluor (FLR Quote): "This stock exploded last week and then went up again today. Ring the register and get into Foster Wheeler (FWLT Quote). This one's just too expensive."

International Paper (IP Quote): "No, no, I like Weyerhaeuser (WY Quote) more, and I like Temple-Inland (TIN Quote) more. IP is just not well run."

Emcore (EMKR Quote): "Fiber-optic play, over-crowded segment. I don't want to go with that one. I like ADC Telecommunications (ADCT Quote) and that's it."

Reliant Energy (RRI Quote): "I don't know. It's not my favorite. I'd steer you toward Dynegy (DYN Quote) instead."
