Cramer Answers Twitter Questions on Alibaba IPO, Yahoo! and Baidu

Jim Cramer answers viewers' questions from the floor of the New York Stock Exchange. This week, he weighs in on the Alibaba initial public offering, which he says stands to be a great deal. Cramer says Alibaba could certainly be priced at $70 and pop to as much as $75, which would make Yahoo! undervalued at $43. Cramer says he fears for stocks like Netflix, Tesla, Apple, Google, Celgene and Gilead -- stocks he believes that will be sold by investors in order to raise money for the Alibaba IPO. In light of this, Cramer says see what the Federal Reserve says this week and wait until the pricing is confirmed, but recognize that if these stocks are knocked down, there will be people who come back to them.
