Jim Cramer, the Street’s Action Alerts PLUS Portfolio Manager and host of CNBC’s ‘Mad Money,’ discussed Alibaba (BABA) while answering social media questions from viewers on the floor of the New York Stock Exchange Tuesday. Cramer said Alibaba had an extraordinary quarter, but the way to play Alibaba is to buy Yahoo (YHOO), and Cramer said you should buy Yahoo right now. Yahoo owns a minority stake in Alibaba. Cramer was asked about what he’d like to hear on Twitter’s (TWTR) earnings call, and he responded that he’d like to hear whether advertising is picking up. Cramer also said that Twitter is a work in progress, and that CEO Jack Dorsey needs time to turn it around. With several oil companies reporting quarterly results this week, Cramer was asked whether Occidental Petroleum (OXY), Chevron (CVX) and Exxon Mobil (XOM) will miss earnings expectations. Cramer thinks everyone misses their numbers, but some companies are better positioned to protect their dividends. Cramer answers questions from social media in a daily segment with TheStreet TV.
