Lightning Round: Be careful, this is extended

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:

Genuine Parts Company: "It's such a good stock. I've been looking at Genuine Parts, what a run that it has had. I also like AutoZone, that is in the zone because our car population is about 12 years old. You've got a good one."

Consolidated Edison: "We have been liking ED for so long and it has bored people. And you know what I think about boredom? The best kind of stock. You've got a good one."

Taser International: "I don't understand why Taser hasn't gone higher, and I am saying that under $20 it is a buy."

New York Community Bancorp: "I am not recommending any of the bank stocks here. They are just too difficult. My charitable trust owns Wells Fargo and that is tough to own. I cannot recommend New York Community, I'm sorry."

Franco Nevada: "It's had a good run, but I'm still going to send you to Randgold, symbol GOLD. Why? Because I like Dr. Mark Bristow [CEO]."

Valspar: "I say ring the register because that deal might be blocked by federal regulators because there is so much concentration in the paint industry."

Alcoa: "I like it ahead of the break-up, and I'm going to like it after the break-up. Particularly the aerospace engineering portion of it. I think Alcoa is cheap, aluminum has come up a little bit. I think you're in a good one."

Nordic American Tanker: "I think that the yield is safe, I think that the business is OK. But remember, they have a lot of ships and if the price comes down for day-rates you're not going to be able to make any money on that thing. But the dividend is safe right now."

Mobileye: "No, still too risky. Mobileye, it's a great company but the stock is too expensive."

Intuitive Surgical: "It's a great machine, I have seen it demonstrated ... I think it's terrific. That said, it has moved up a lot and I fear competition coming in at the year end from Johnson & Johnson. So let's be careful, I think the stock is extended."
