Cramer Shares His Thoughts On Blink Charging, Dynatrace And More

On CNBC's "Mad Money Lightning Round," Jim Cramer said that Ibio Inc (NYSE:IBIO) has an interesting chart. He needs to do more work on the stock.

Cramer didn't like the tone of an article about insider selling in Vaxart Inc (NASDAQ:VXRT).

Dynatrace Inc (NYSE:DT) has been a winner, but it's a very expensive stock in terms of price-to-earnings ratio, said Cramer. He advised his viewer to stick with the stock.

Rosetta Stone Inc (NYSE:RST) is an interesting, good household brand stock, said Cramer. He added that a short-seller recommended the stock as a buy and he sees that as a good sign.

Cramer can't recommend Blink Charging Co (NASDAQ:BLNK). He likes Tesla Inc (NASDAQ:TSLA).
