NEW YORK (TheStreet) -- Here's what Jim Cramer had to say on CNBC's "Squawk on the Street" Tuesday.
Piper Jaffray upgraded Boston Scientific (BSX - Get Report) to buy from hold. Cramer said the medical device industry was "hot last year" and it will "stay hot" in 2014. BSX closed 3.5% higher at $13.98.
Keefe Bruyette & Woods upgraded regional bank Comerica (CMA - Get Report) to hold from sell. Regarding the Federal Reserve's plan to taper its asset purchases, Cramer said that "as taper goes, you buy the regionals." CMA rose 3.9% to $49.51.
Credit Suisse downgraded 3D Systems (DDD - Get Report) to hold from buy. Cramer added that the "group still has a lot of momentum," but the analyst prefers Stratasys (SSYS). DDD dropped 5.4% to $85.63.
Morgan Stanley upgraded Seagate Technology (STX - Get Report) to buy from hold. STX was a heavily shorted stock, Cramer said. "People were really shooting against this" but because of the strong pricing of disk drives, they can "forget about it," he added. STX rose 4 cents to $61.24.
"Maybe things are slowing" at Netflix (NFLX - Get Report), Cramer said, after Pacific Crest warned that the stock could fall to $200 following the company's earnings report, which is scheduled for Wednesday. NFLX fell $1.33 to $328.71.
Wells Fargo initiated Hain Celestial Group (HAIN - Get Report) as a hold, but Cramer called the company remarkable. He added, "It is the next great food company in this world." HAIN fell by 1.9% to end the day at $95.74.
