Cramer: What Ambarella's earnings can do to GoPro

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:

Monsanto: "Just stay long. I'm typically not an arbitrager but everything I listen to and my partner David Faber makes me think that there's something coming. You probably want to be in MON."

SecureWorks Corp: "I am so gun shy on cybersecurity, I'm just going to go back to Cyberark. We had Palo Alto on the show last night and I thought he told a great story. Does anybody really care? I do but I don't want to push the group hard."

Celator Pharmaceuticals: "Come on man, the gain has been made! Cha-ching, ka-ching, cha-ching. Let's move on."

GoPro: "Ambarella reported a good number tonight, and they're a drone company, people are going to give a little halo to GoPro. I think if you can get to $12 it is time to skeedaddle."

Dow Chemical Co: "A charitable trust name. I think the stock is actually 10 points undervalued. Right here, right now, I want to buy it."

Fitbit: "I'm snake bit from Fitbit. I liked Fitbit but it's like, I can't take the Fitbit pressure. There we are ... I just feel you have to be very careful in this."

Big Lots: "Big Lots had a good quarter, what can I say. It's time for those stores where you get the bargains. I think you have to wait for it to come in a little because it had a run. But Big Lots is back."

Nokia Corp: "Nokia is not back. Now it's just a river in Finland."
