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:
Berkshire Hathaway (B Class): "If anything, I am interested in buying more. I think the stock is incredibly undervalued."
Westar Energy: "A good utility company. I happen to favor Dominion and my charitable trust name American Electric Power."
WEC Energy Group: "We are in one of those markets right now that likes the super-juiced industrials. It's ... leaving WEC alone. I say stick with it, buy some weaker. I have no problem with it."
SAP: "I think SAP is doing incredibly well and I would be a buyer of SAP. By the way I think Accenture is too low. I would buy that one, too."
Mettler-Toledo International: "An old-fashioned industrial. A little overvalued right now but I have no problems buying it on weakness."
Halyard Health: "Halyard Health is a spinoff of Kimberly-Clark and has been a disappointment and I cannot recommend people to buy it. Frankly I have been kind of flabbergasted that they haven't been able to put up better numbers."
McDermott International: "I think you hold on to the rest. You're playing pretty much with the house's money soon and I think this infrastructure play is a good one. A lot of people left it for dead. It is not dead. Nice call."
Freeport-McMoRan: "I think FCX has completed a lot of the balance sheet work that it needed to do. Obviously it had to sell some good assets, but that is OK. I like copper here and I think the company has gotten its act together and therefore I think it can go higher."
