Jim Cramer Talks Shopify, Sierra Wireless And Aerojet Rocketdyne

On CNBC's "Mad Money Lightning Round," Jim Cramer said Shopify Inc (US) SHOP is a pricey stock. He added that after negative comments from Citron's analyst Andrew Left, he won't pound the table with the stock, but he also won't tell investors that it is time to go.

Sierra Wireless, Inc. (USA) SWIR is a good company, said Cramer, but he would rather own Broadcom Ltd AVGO in the communications sector.

Cramer likes Aerojet Rocketdyne Holdings, Inc. AJRD, but he prefers Raytheon Company RTN.
