Lightning Round
Mad Money host Jim Cramer takes viewer calls on particular stocks and tells them whether they're a buy or a sell.

Renren : This social networking site's valuation is just too expensive, Cramer said. Earlier, he recommended investors buy and then quickly sell after its initial public offering. He would definitely sell now.

"I don't see any value in these Chinese stocks," he said. "They are too expensive."

Rubicon Technology: Cramer said this stock is too hard for him to analyze, adding he doesn't like the light-emitting diodes market right now. For those that have to be in this space, he would rather go with Cree .

Best Buy : Cramer said he is a seller of anything to do with electronic goods other than Amazon.com .

Raytheon : This may be a very inexpensive stock, but Cramer thinks it's "going nowhere fast." The "Mad Money" host said he doesn't see a catalyst or any takeovers in the business and can not recommend it.
