It's that time again! Jim Cramer rang the lightning round bell, which means he gave his take on caller favorite stocks at rapid speed:
Synergy Pharmaceuticals: "I feel like if the data is good you're going to get a takeout bid. If the data is not that good I'm not sure what it's worth. We see with these things like Regulus, if they go right it's just unbelievably good. If they go bad, it's unbelievably bad. And that's why it's been so hard for me to opine on it because it seems very binary to me. And I don't like to comment on the binary. But obviously if the news is good, wow."
Charter Communications Inc: "I like Charter Communications. I happen to like the cable companies very much. This seems to be one of the best domestic businesses. You're in good shape."
Keryx Biopharmaceuticals: "We don't care where a stock has come from, we care where it is going to. This happens to be a stock I have to tell you that I think does have great speculative capabilities. I'm going to say stick with it. I don't want to buy more here because it's had a move, but I do like it because I happen to like the ones that are working on renal that are doing so well in phase three."
