RealMoney Radio: Knight Fever

The first caller to his "RealMoney" radio show asked Jim Cramer about financial services company Knight Capital Group(NITE Quote).

Knight CEO Thomas Joyce, is a college friend of Cramer's and the two happened to share breakfast recently, so Cramer took the opportunity to discuss business.

"Knight is a fabulous niche player," he said. "I think it will have the single best results of any firm on Wall Street when it announces earnings."

"Buy now at $15," he said.

The next caller asked about South African alternative energy company

Sasol(SSL Quote), which has seen its stock slaughtered over the past few weeks as tightening by the Fed squeezed speculative money out of the stock market.

The company grew up during South Africa's period of apartheid and as a result of trade boycotts from the U.S. and Europe it had to become very innovative in a way that its current competitors didn't need to. That is now the company's competitive advantage.

The stock is down $9 and currently yields 2.45%, Cramer said. "I am shocked it has fallen so far. Buy it."

The next caller asked about Kroger(KR Quote).

"It's a very interesting stock," said Cramer, suggesting that the company had reinvented itself, but that factor didn't turn him on enough to become a buyer. Wal-Mart, he said, was expanding its business domestically due to difficulties overseas and that would make life hard for supermarket players such as Kroger.

One caller asked Cramer about Abercrombie & Fitch(ANF Quote), which had recently taken a beating in the market despite solid earnings.

"I don't typically blame short-sellers," said Cramer. "But there are sellers that are convinced that the good quarter won't last."

He said sales were up 3.3% and that overall revenue was up 17% and explained that by using his rule of paying twice the growth rate, he'd be a buyer up to 34 times future earnings.

"I think the stock could double and not be that expensive," he said.

"What are we going to do with New York Stock Exchange(NYX Quote)?" asked the next caller.

Cramer observed that NYSE CEO John Thain is going to have to pay more to buy an additional market exchange in Europe but probably not that much more than the current offer.

"Twenty-three of the last 24 private equity deals have been in Europe," he said. "Thain will be able to capture that business when the deal goes through."

"You want to be there. I like the stock."
