NEW YORK (TheStreet) -- Did you miss last night's "Mad Money" on CNBC? If so, here are Jim Cramer's top takeaways for today's trading.
Domino's Pizza (DPZ) - Get Report, Papa John's (PZZA) - Get Report and Papa Murphy's (FRSH) - Get Report: Competition is heating up in the pizza wars, with all these pizza giants vying for your business. But with shares of Domino's up 54% for the year, Papa John's up 79% and Papa Murphy's up 128%, which one is the best investment?
The key metric in the pizza business is same-store sales, and among the three Domino's is the clear winner, with not only the strongest but also accelerating sales at its 11,700 locations.
As for the stocks, it just so happens that Domino's is also the cheapest of the three, Cramer said, trading at 28 times earnings, while Papa John's trades at 31 times and Papa Murphy's at 33 times earnings.
Cramer said he can't make a case for owning either of the others and is sticking with Domino's and its CEO Patrick Doyle. That stock is up nearly 1,000% since he first got behind the company's turnaround efforts five and a half years ago.
GW Pharmaceuticals (GWPH) - Get Report: In an exclusive interview, Cramer sat down with Justin Gover, CEO of GW Pharmaceuticals, the biotech that's studying the medicinal uses of marijuana, with a stock that's up 91% so far in 2015.
Gover explained that GW is pursuing real science, using the marijuana plant as a source for real medications that can treat everything from epilepsy to diabetes and even cancer. None of GW's end products contain THC, the chemical in marijuana that makes you high, Gover continued.
GW's first product, Sativex, is currently in four Phase III trials to treat a drug-resistant form of epilepsy. Gover said those trials will offer important insights into how well Sativex is working when they complete in early 2016.
GW is also making an investment in America, as the British-based firm is building the infrastructure needed to do more clinical work here in the United States. Even Gover himself will be relocating to the U.S. shortly, he noted.
Cramer said he's always been a fan of Bed Bath and has shopped there for years. But if there was a newly remodeled Target (TGT) - Get Report close by, he'd probably shop there, or just order what he needs from Amazon.com (AMZN) - Get Report or another retailer.
Customer loyalty is waning, he said, and it's only going to get tougher for retailers. Some stores, like Home Depot (HD) - Get Report, can overcome the trend. Others, like Bed Bath, are only going to see their customers continue to shop wherever is most convenient, which may or may not be at Bed Bath & Beyond.
