The first "RealMoney" radio caller on Wednesday's show asked Jim Cramer for his take on

BJ Services

( BJS).

"You're in the sweet spot there" because the company does pressure pumping, said Cramer. When you are running out of oil in old wells, BJ Services will find a way to get at that oil.

With crude prices at these record highs, remedial work on existing wells is a huge business because it's not worth scraping the bottom of the well, he said.

And Cramer said that the company has a near hammerlock on the business. At two points from its 52-week high, he said that this is a buying opportunity.

Cramer said that

Schlumberger

(SLB) - Get Report

,

Baker Hughes

(BHI)

and

National Oilwell Varco

(NOV) - Get Report

are good stocks for similar reasons and that he is "indifferent to which one you buy."

The market is down so all of these stocks are weaker. "The market is throwing a sale," he said.

He said that even though

Bank of New York

(BK) - Get Report

"just continues to motor along ... it's one of the least-best banks out there."

The bank has a good ADR business, but it doesn't have the growth that Cramer likes. Instead, he said that

Commerce Bancorp

(CBH) - Get Report

has the best growth on Wall Street. Cramer owns the stock for his

ActionAlerts PLUS charitable trust portfolio.

Cramer likes

Martek Biosciences

( MATK) because the company makes a proprietary product -- nutritional oils for infant formula. And he said that it is a great growth story.

But the company falls under the category of health care, a sector Cramer said has not been spared.

He told a caller not to swap out of Martek for cash, but to overweight his portfolio. That means lightening up on health care stocks and owning a greater percentage of gold, silver or machinery plays.

A caller said that he bought

Sears Holdings

(SHLD)

at $100 and wanted to know if it's time to sell the stock now that it is above $140.

Cramer said that the stock, which he owns for his

ActionAlerts PLUS, is a high-quality investment that is going to move higher.

Cramer also said that he has liked

Crocs

(CROX) - Get Report

since the company went public, but he said that there is a "gigantic short position in the stock."

"When I see this large a short position, I get nervous," he said. The company is about to report, and if it does a great job and decides to issue more stock, then no short squeeze will happen.

In a short squeeze, stock prices move higher when investors who had bet against the stock are forced to buy more of it to cover their positions.

So Cramer said he would wait to see if stock falls. If it does, he said that would be a chance to buy.

Finally, he told a caller that he likes

Lowe's

(LOW) - Get Report

because it has great management. He also said that it could have more room to grow than

Home Depot

(HD) - Get Report

.

He said that it also has more women shoppers than Home Depot does, and that he blesses it as a trade and as an investment. When Cramer talks about holding something as an investment, his time frame is between 6 and 18 months.
