Lightning Round: What Dorsey will do for Twitter

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:

United Continental Holdings: "I like Oscar Munoz [CEO]...I think it's good. I think that group has bottomed here and liked it. I know some analysts want to say negative things. Not me!"

Twitter: "I wanted Jack Dorsey [new CEO] I think Dorsey is going to do a good job. I was kind of hoping he would resign from Square and let someone else handle that. But the changes are coming fast and furious at Twitter and he is liked by the staff and he cares about those who Tweet."

Sprint: "I don't like that balance sheet and the government seems to not want to let anybody merge in that. If that stock rallies, I think you want to check out of it, not check into it."

Intrexon: "The stock is down way too much. Now we know from the problems with Valeant that a lot of these stocks have come down tremendously. I think that one is too low to sell."

Sierra Wireless: "This group is under tremendous pressure, and I think the group is bouncing back. That one is down 52 percent [year to date]. I prefer Skyworks Solutions, which has come down a lot and had a beautiful quarter."

Amag Pharmaceuticals: "That is way too hard. We've got stocks like Celgene that are down huge, and Gilead is also down huge. Why not go with a Celgene? You've got an opportunity here. It's a big discount. That's the way to go."

Motorola: "I think it's done. I think you've just got to move on to the next name. I'm not there for Motorola Solutions anymore."

Gogo Inc: "No, we felt that Gogo is too controversial. It's got guys who love it, guys who hate it. We don't need that. We've got so many stocks where it is just a good solid story. We don't need to dive into controversy."

International Paper: "IP has been down because the price of liner board has been cutting down. But this is a 4 percent yield now, I think this is the level where the decline is probably going to bottom out and you want to buy IP."
