NEW YORK (

TheStreet

) -- 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

Tuesday's "Mad Money" show

fared today.

optionsXpress

: Cramer spoke with optionsXpress CEO David Fisher, who said that the ability to trade options electronically makes them available to everyone, including retail investors. He noted that optionsXpress has more than $6 billion in assets and that about 10% of options traders use the company's services. Cramer said that "options are back in a big way" and complimented Fisher on building "quite a good business."

On Wednesday, optionsExpress closed up 39 cents, or 2.3%, at $17.33.

XTO Energy

(XTO)

: Cramer also spoke with XTO's Bob Simpson, who cited the company's continuing profitability despite the record lows in natural gas and predicted a recovery for natural gas as supply dwindles. Cramer said Simpson has "made people fortunes" and that natural gas is "clearly the way to go if you care about climate change."

On Wednesday, XTO added 89 cents, or 2.3%, to $39.34.

Comcast

(CMCSA) - Get Report

: New FCC rules are allowing Comcast and

Time Warner

(TWX)

to buy more companies, which makes them "more attractive than I thought," Cramer said.

On Wednesday, Comcast gained 38 cents, or 2.3%, to close at $16.85, while Time Warner added 60 cents, or 2.2%, to $28.47.

Potash

(POT)

: In his

"Lightning Round"

segment, Cramer said Potash is "coming under pressure," but he still called it a buy and predicted it would recover. He advised selling

Monsanto

(MON)

and buying Potash.

On Wednesday, Potash slid 77 cents, or 0.8%, to $91.04, while Monsanto added 8 cents, or 0.1%, to $83.48.

Altria

(MO) - Get Report

: Cramer owns Altria for his

Action Alerts PLUS

charitable trust because of its "great" dividend. He said the stock "has $20 written all over it."

On Wednesday, Altria edged up 7 cents, or 0.4%, to close at $18.59.

Citigroup

(C) - Get Report

: Cramer saw another 60 cents of upside for Citigroup but recommended waiting for the stock to pull back below $4 before buying.

On Wednesday, Citigroup closed down 2 cents, or 0.4%, at $4.66.
