NEW YORK ( TheStreet) -- Here's what Jim Cramer had to say on CNBC's "Squawk On The Street" Tuesday:
National Oilwell Varco (NOV - Get Report) is a terrific technology company, so to see it downgraded has Cramer worried. He is not worried about Illinois Tool Works (ITW - Get Report), however, after the company's CEO passed away last week. Cramer said he still likes this the company.
Investors were more worried about National Oilwell Varco, pushing its shares down 2.6% at the close Tuesday, while Illinois Tool Works stock was unchanged.Cramer is also bullish on MarkWest Energy Partners (MWE - Get Report), saying this company's secondary offering went very well, which means things are working. He also said that if Norfolk Southern (NSC - Get Report) is able to meet its numbers, coal may have indeed bottomed. MarkWest's shares ended the day up nearly 1% while Norfolk Southern was up 1.2% He is less optimistic about Boston Scientific (BSX - Get Report). Cramer said this group has been in turmoil as of late, and the positive momentum at Boston Scientific may be stopped in its tracks. He ended on a positive note by saying people really like using Yelp (YELP - Get Report), which is why this company is among the best-performing social media stocks this year. Boston Scientific's shares were down slightly at the close but Yelp shares screamed higher by 6.6%.
