Jim Cramer's Stop Trading! Stock Picks and Comments, April 20.

Recap of Jim Cramer’s comments on Stop Trading! Friday April 20. Click on a stock ticker for more analysis:

IBM (IBM): Although Cramer thinks IBM could rise 15% because unpopular CEO Sam Palmisano is taking a "permanent intellecutal vacation," he notes the stock could fall 20% if a new chief isn't chosen soon. Cramer suggested "maybe IBM could get a board of directors," which he thinks the company badly needs since it took so long to let Palmisano go.

Apple (AAPL), Nokia (NOK), Motorola (MOT): Cramer says Apple is the one tech stock worth buying, since Wednesday is the final quarter before the release of its iPhone. He would pick up the stock at $90, especially since NOK and MOT are not doing well, and adds the only reason NOK is up 6 points is not due to its own strength but MOT's weakness.
