Jim Cramer's Stop Trading! Stock Picks and Comments, 8/20/07

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

Fannie Mae (FNM): Cramer would stay off the Fannie Mae bandwagon, since the Bush administration and the FNM's top regulator, James Lockhart of the Office of Federal Housing Enterprise Oversight, have a "chokehold" on the company's mortgage portfolio. Cramer would not make a move unless this changes.

Countrywide (CFC): Cramer says he needs to see evidence to back up the bank's bullish comments.

Lamar (LAMR), Celgene (CELG) and PDL BioPharma (PDLI): Lamar's video billboards may be too "eye-catching" and may be limited due to safety regulations. He is not sure about CELG, because it should be working but isn't. He sees PDLI as a possible takeover target after the departure of CEO Mark McDade.
