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 Friday's "Mad Money" show fared today.


Apple ( AAPL): Cramer predicted that this week would offer investors the perfect buying opportunity in Apple. He said that iPhone shipment numbers would likely disappoint today but that AT&T ( T)'s earnings report would be a positive for Apple, making Tuesday the ideal day to buy the stock.

On Monday, Apple closed up $1.81, or 1%, at $189.86, and AT&T added 30 cents, or 1.2%, to $26.

Boeing ( BA): Wednesday's the day to buy Boeing, Cramer said, anticipating that any more Dreamliner delays will create weakness in the stock.

On Monday, Boeing closed up 26 cents, or 0.5%, at $53.45.

Wells Fargo ( WFC): Cramer also said he'd buy Wells Fargo, which he owns for his charitable trust, Action Alerts PLUS , on weakness.

On Monday, Wells Fargo gained 5 cents, or 0.2%, to close at $30.07.

Starent ( STAR): Cramer said it's time to sell Starent, which was originally a part of his mobile Internet index, now that it's been bought by Cisco ( CSCO). He suggested ARM Holdings ( ARMH) as a replacement for Starent.

On Monday, Starent slid 12 cents, or 0.4%, to $33.74; Cisco added 23 cents, or 1%, to $24.25; and ARM gained 32 cents, or 4.2%, to $7.88.

Cogent ( COGT): For Speculation Friday, Cramer looked at two homeland security plays. Cogent is a pure play on fingerprinting technology, said Cramer, and is less risky than L-1 Identity Solutions ( ID). He was not in a rush to buy either, though, and recommended waiting for a pullback in the market.

On Monday, Cogent added 39 cents, or 4.1%, to $10.03, while L-1 Identity Solutions gave up 2 cents, or 0.3%, to $6.84.

Hatteras Mortgage ( HTS): Cramer said that Hatteras' 16% yield is high enough to worry investors and that the stock is below his standards for financial stocks.

On Monday, Hatteras closed up 22 cents, or 0.8%, at $28.01.
