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.
Apple (AAPL - Get Report): Cramer used Apple as an example of how company fundamentals matter less to the market right now than China, Greece and oil prices. That's why Apple rallied on Thursday, coinciding with a copper rally and positive news from Greece, rather than earlier in the week on news that Apple has 25% of the smartphone market and other company-specific news. Since Apple doesn't depend on global growth, Cramer said, so Apple would have been a buy on the down days this week because of its fundamentals. On Friday, Apple closed up $1.71, or 0.9%, at $200.38. Garmin (GRMN - Get Report): Cramer put Garmin in his Sell Block on Thursday, explaining that built-in smartphone navigation systems are threatening Garmin's standalone navigation system business. He said that without personal navigation, Garmin is worth about $26 a share. He told viewers to sell the stock.
