Cramer Weighs In On Lumentum, American Airlines And More

On CNBC's "Mad Money Lightning Round," Jim Cramer said that Sarepta Therapeutics Inc SRPT is good and he would own it, but he prefers Vertex Pharmaceuticals Incorporated VRTX.

Cramer would be careful with Lumentum Holdings Inc LITE because this group has always hurt him when it has gotten this hot.

Royalty Pharma plc RPRX is a good opportunity, said Cramer. He is a buyer of the stock.

Cramer sees more upside potential for American Airlines Group Inc AAL. In the long term, he likes Southwest Airlines Co LUV better.

TJX Companies Inc TJX is a very large position for Cramer's charitable trust and he thinks that it is a buy.

Instead of Southern Co SO, Cramer would rather buy Sempra Energy SRE.
