In comments on his MAD MONEY this evening, Cramer was giving more advice for a record-breaking market. He said a great way to make money in a rally is to find some of the lesser-known names that have been overlooked.

[Oddly enough, this is a complete backflip from his advice last night, when he said to go with the big tech titans. But who's keeping track? Ahem.]

Today he said Riverbed Technology, Inc. (NASDAQ:RVBD) is one that could be a big big winner like his old DivX Inc. (NASDAQ:DIVX) call. He said RVBD is up 20% but you might not have missed it. He said they are actually beating Cisco Systems, Inc. (NASDAQ:CSCO) at its own game. Cramer said this is a great speculative tech stock.

Cramer said Riverbed is actually a best-of-breed WAN product company, but it isn't even profitable yet. He said the company's revenue growth has been large, and its technology is the best out there. Riverbed currently has deals with HP, McData, NEC, and others. He thinks the new estimates for RVBD are conservative, and it could blow away estimates one quarter out.

RVBD closed down 4% at $18.05 in regular trading but popped up 12% to $20.25 in after-hours after Cramer touted this stock.
