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.

Hertz

(HTZ) - Get Report

: Rental car company stocks have surged since March 6 lows, with Hertzy up 300%,

Avis

(CAR) - Get Report

up 3,000% and

Dollar Thrifty

(DTG)

up 3,100%. Cramer said Hertz is the winner among them because it has the most cars to sell in the used-car market, which is where rental car companies make most of their money. Cramer said to stay away from Dollar Thrifty, which has the fewest vehicles to sell, and Avis.

On Friday, Hertz added 58 cents, or 5.7%, to $10.74, while Dollar Thrifty closed up 39 cents, or 1.5%, at $26.18, and Avis gained 34 cents, or 2.9%, to $12.12.

"Lightning Round"
