Cramer Gives His Take On Slack, CME Group And More

On CNBC's "Mad Money Lightning Round," Jim Cramer said Xilinx, Inc. XLNX has too much exposure to China.

Cramer advised a viewer with a long position in Occidental Petroleum Corporation OXY not to buy more at a lower price.

Onespan Inc OSPN is good, but Cramer likes Okta Inc OKTA better.

The cannabis stocks aren't working, so Cramer is not a buyer of Innovative Industrial Properties Inc IIPR.

Slack Technologies Inc WORK is a good company, said Cramer. He would buy some.

Cramer would buy half of a position in GW Pharmaceuticals PLC- ADR GWPH now and he would wait and see if cannabis stocks have one more leg down.

Covanta Holding Corp CVA told a great story when the management was on the show. Cramer is surprised that people don't trust its distribution. He feels confident about it.

CME Group Inc CME is teriffic and Cramer really likes it.
