Commercial real estate is still hot and

Vornado

(VNO) - Get Report

is the way to play it, Jim Cramer said on

CNBC's

"Stop Trading!" segment Friday.

Vornado, the real-estate investment trust run by Steve Roth, is benefiting from strong demand for office space among new businesses. "Not all real estate is created equal," says Cramer, who is less bullish on residential property. "Take a page from Vornado, they know what they're doing."

Among other stocks, Cramer called

Bookham

( BKHM) a "quintessential fiber-optic play" that is levered to the same fundamentals that led to
