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.

JPMorgan ( JPM): Cramer said that JPMorgan, which he owns for his Action Alerts PLUS charitable trust, was on point when it said that the economy is improving. He said he has faith in JPMorgan's CEO, Jamie Dimon. On Friday, JPMorgan closed up 76 cents, or 2.1%, at $36.89.

Xilinx ( XLNX): Cramer spoke with Xilinx President and CEO Moshe Gavrielov, who said that the company's problems meeting demand are over. Cramer, who recommended the stock on March 17, said he'd stick with it. On Friday, Xilinx closed flat for the dat at $20.26.

Nokia ( NOK): Cramer put Nokia in his Sell Block because of its disappointing quarter. He said Nokia is a weak player in the cellphone industry, and it's quarter does not indicate that the whole industry is in trouble. On Friday, Nokia closed down 7 cents at $13.39.

Dell ( DELL): He also put Dell in the Sell Block, because while Intel ( INTC) had a great quarter, Dell disappointed. On Friday, Dell closed down 8 cents at $12.67.

Apple ( AAPL): Apple is a buy, Cramer said, ahead of its earnings next week, and encouraged viewers not to be distracted by the weaker players in tech. On Friday, Apple closed up $4.23, or 2.9%, at $151.75.

DryShips ( DRYS): In his "Lightning Round" segment, Cramer recommended Nordic American Tanker ( NAT) and advised viewers to sell DryShips. On Friday, DryShips slid 11 cents, or 1.9%, to $5.82, while NAT lost 44 cents, or 1.4%, to close at $31.37.
