Cramer's 'Mad Money' Follow-Up: Sept. 18

Every night on "Mad Money," Jim Cramer offers market commentary and general investment advice, and he makes calls on specific stocks, both of his own choosing and in response to viewer requests. He relies on his many years of experience and strong track record, and he takes full responsibility for his calls.

"I never shirk from admitting my mistakes; instead, I dwell on them to learn from them. I change my mind, I take losses, I own up to them," Cramer has said.

Here we track some of his calls from the previous episode of "Mad Money" and find out, at least in the very short term, how the stocks are performing. Keep in mind that Cramer might not have been recommending that viewers take immediate action on a stock. And, of course, it's up to the individual investor to do his or her own homework.

That said, here's how some of the stocks that Cramer talked about on Thursday's "Mad Money" show fared today.

---

Range Resources(RRC Quote): Cramer spoke with Chairman and CEO John Pinkerton about the natural gas industry's image problem in Washington, which Pinkerton blamed on the industry itself. Cramer said that if natural gas gets the recognition it deserves, Range Resources could be a huge stock.

On Friday, Range Resources closed down 32 cents, or 0.6%, to $51.26.

Freeport-McMoRan(FCX Quote): On Thursday's show, Cramer said Freeport is headed higher. On Friday, it slipped $1.33, or 1.9%, to $70.14.

Yahoo!(YHOO Quote): Yahoo! also is on its way up, said Cramer, as it catches up to the rest of the market. On Friday, Yahoo! lost 11 cents to $17.39.

BP(BP Quote): Cramer owns BP for his Action Alerts PLUS charitable trust and didn't want to sell it on Thursday. He liked its 6% yield and said it's a "better company" than it used to be.
