Lightning Round: I'm surprised this is so low

CNBC. Jim Cramer is concerned about one particular group of stocks, and warned to stay far away. He also gave his take on caller favorite stocks. · CNBC

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:

Twitter (NYSE: TWTR): "I like Twitter, my charitable trust owns it. I think at this point the stock has come down so much, I think that if it went down 4 or 5 more points there would be a lot of companies wanting to buy it. But I don't know who the CEO is going to be."

Lululemon (NASDAQ: LULU): "I am in agreement with Morgan Stanley. I thought that the selloff was overdone and it happened while I was out in California. I took a look at the stock this weekend and was surprised that it was down so low. So were they, and I think they are right."

Kinder Morgan (NYSE: KMI): "This group is under heavy liquidation. It makes no sense to me at this point because a lot of them are connected with natural gas. I like KMI, this was actually the first day they have been up in a very long time."

Consolidated Edison: "A lot of times these have to do with just yields. At this point I think Con Ed is back to 4 percent yield, if it drops anymore I think you are absolutely fine on Con Ed. I like their asset light method of not having to have coal plants... and they're not building any nukes."

Powershares (NASDAQ: QQQ): "When you say you are just out of college, I do want you to take a little more risk. I've been working with some generational investing, and I think you can pick the best of the best in that QQQ. I prefer you to do that."

Northern Tier: "It yields 19 percent now, which you know I actually think is a bit of a red flag. That is a little too high, so let's be careful and not be greedy is the way I would look at it."

ConforMIS (NASDAQ: CFMS): "I've done a lot of work on that thing, I really don't think they made false statements. I think that is just pretty much the cost of doing business. This stock has come down a great deal and I don't think it's really worth selling down here. I really don't."

Exact Sciences: "When the stock was higher we decided it was time to ring the register. We felt that the best had happened. I'm sticking by that."
