"When OPEC didn't cut, everyone thought oil would open down $10, down $7," said Jim Cramer on CNBC's "Stop Trading!" segment on Monday. "It opened down a couple of bucks, and then reversed. This is a sign of global strength."

Last week, Cramer said that JPMorgan ( JPM) was going higher and that if it broke into the $20s, " the rally might have legs." The stock was recently trading at about $24.20. Cramer said that betting against CEO Jamie Dimon "has always been foolish, always, and it will be foolish again."

"There's just so much excitement about Cisco ( CSCO) vs. Hewlett-Packard ( HPQ)," said Cramer, both of which he owns for his Action Alerts PLUS charitable trust. "A lot of the underlying current is where would VMware ( VMW) be best."

Cramer said that Vmware eventually "has to be a sought-after product for these two" and that investors should keep their eyes on VMware and EMC ( EMC).

"EMC is the class of the field, and they own VMware," he said. "EMC has been $10 for what seems like ages, but maybe this guy is undervalued."

At the time of publication, Cramer was long Cisco, JPMorgan and Hewlett-Packard.
