Jim Cramer, portfolio manager of Action Alerts PLUS and host of CNBC’s Mad Money, said the market could retrench further due to what’s happening in China, but eventually it will get oversold and that’s when you buy. He made those comments while answer viewer questions from social media on Friday from the floor of the New York Stock Exchange. Cramer was asked whether MetLife(MET) presents a buying opportunity after this week’s selling, and he responded that the best insurance company to own is Traveler’s(TRV), followed by AIG(AIG). A viewer wanted to know if GameStop(GME) still has marketplace opportunity given the increase in online games. Cramer replied that he’s been recommending Activision(ATVI) and Take Two Interactive(TTWO). Finally, Cramer said he’s not a fan of Garmin(GRMN), saying ‘if you have trouble owning Fitbit(FIT), you should really have trouble owing Garmin.’ Cramer answers viewer questions from his Facebook(F) page and on Twitter(TWTR) where he’s @jimcramer.
