Here's what Jim Cramer had to say about some of the stocks during the Mad Money Lightning Round:

Berkshire Hathaway (BRK.B) : "That's just a buy, buy, buy. I love their portfolio of businesses."

Align Technology (ALGN) : "Let's give it a little break, then do some buying."

Seaspan (SSW) : "No, this one has moved up too much."

Criticare Systems Inc (CMD) : "This stock has moved so much. I like Thermo Fisher Scientific (TMO) a little better."

IAC Interactive (IAC) : "I think the parts are worth more than the whole."

Symantec (SYMC) : "Accounting irregularities equals sell. That's my rule."

CoreSite Realty (COR) : "The data centers have been hot, but the REITS have not. I'm a buyer of this stock, not a seller."

Hi-Crush Partners (HCLP) : "This sector has gotten way too hot."

Cramer and the AAP team say they're trimming El Lilly (LLY) and adding WestRock (WRK) and Textron (TXT) . Find out what they're telling their investment club members and get in on the conversation with a free trial subscription to Action Alerts PLUS.
