After the market closed Thursday,

KB Home

(KBH) - Get Report

reported a bad quarter and everyone panicked, but the stock is up "nicely" on Friday, Jim Cramer said on his

"RealMoney" radio show Friday.

"When a company reports really bad news and the stock still goes higher, you need to figure out a way to get into that stock," he said.

Cramer said he's not saying to get into KB Home, which is up $1.65, but people watch to see when this happens again to a homebuilder.

Masco

(MAS) - Get Report

CEO Richard Manoogian, who appeared as a guest on Cramer's "Mad Money" TV show Thursday night, was not bullish on the housing market, Cramer said.

This is good too, Cramer said, because if Masco was bullish, that would mean the company would build more houses. However, the fact that Manoogian is a bear means Masco will stop building homes and the home inventory will eventually get worked off, he said.

The market has been making a mistake with

Boeing

(BA) - Get Report

, a company which has been doing well, but a stock that has been going down, Cramer said.

"You had to wonder when it would dawn on the market that

Airbus

can't make planes," he said. "You had to wonder when the market would figure out that Airbus' problems would eventually translate to Boeing's bottom line."

Today is the first day since the Airbus "debacle" that Boeing is up on a down day in the market, he said, adding that the action of Boeing's stock tells him that Airbus' problems are getting "critical," and the market is "embracing" Boeing.
