Caterpillar

(CAT) - Get Report

recently made a statement when it held a shareholders' meeting in which it declared that the company's business is "smoking good" and its stock is too cheap, Jim Cramer said on his

"RealMoney" radio show Friday.

The company raised its dividend, he said, advising a caller to the show that it's not too late to buy Caterpillar's stock.

Last week,

Best Buy

(BBY) - Get Report

reported a great quarter, but people also learned that the company's New York stores were not performing too well, Cramer told a caller, who inquired about it.

Ten days ago,

AU Optronics

(AUO)

came out and said they have too much inventory.

Since AU Optronics manufactures and sells the liquid used in LCD TVs, people thought its inventory must be high because Best Buy wasn't doing well.

Everyone began selling Best Buy, but in fact, even though the company's New York stores were underperforming, Best Buy was doing great overall and it was revealed that AU Optronics' inventory problem was caused by

Corning

(GLW) - Get Report

.

Best Buy is a good story in a down market, Cramer said, but it is not a buy right now.

Although Cramer told a caller he has taken a terrible beating with

Nabors

(NBR) - Get Report

, which he owns for his charitable trust,

Action Alerts PLUS, he believes the worst is over for this company.

What happened is that bankers convinced Gene Eisenberg, the company's CEO, that he could borrow money to buy back stocks, Cramer said, and overnight the stock went from $36 to $28. It was a wrong move and the stock has come down a lot since then, he said. But Cramer said he believes the damage has been done and recommends buying the stock. "I would buy," he said.

It is the best driller in the world, he said.

Cramer told a caller he believes the fall will be a good time for

Amgen

(AMGN) - Get Report

. The stock has real value and Cramer said he has never seen it cheaper that it is now.

Amazon.com

(AMZN) - Get Report

is a "dog," Cramer said, adding he likes

Barnes & Noble

(BKS) - Get Report

better.

He also told the caller to get out of

Titanium

(TIE)

because it's too dicey and move into

Boeing

(BA) - Get Report

.

Cramer gave two thumbs "way up" to

MasterCard

(MA) - Get Report

and told a separate caller to wait for

Bank of America

(BAC) - Get Report

to go a little lower before buying.
