Lightning Round: Jim Cramer Advises His Viewers On Mallinckrodt, GoPro And More

On CNBC's "Mad Money Lightning Round", Jim Cramer advised his viewer not to sell Alteryx Inc AYX. He hears nothing but good things about the company.

Mallinckrodt PLC MNK paid too much for Achtar, said Cramer. He isn't a buyer of the stock.

Cramer doesn't agree with investors who think that Charles River Laboratories Intl. Inc CRL didn't post a good quarter. He believes it was all right and he likes the company.

Cramer though that GoPro Inc GPRO would have posted a better quarter. He still thinks the company could be all right.
