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

Dynatrace Inc 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 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.
