Jim Cramer's Stop Trading! Stock Picks and Comments 5/31

Recap of Jim Cramer’s comments on Stop Trading! Tuesday May 30 Click on a stock ticker for more analysis:

Chesapeake Energy (CHK): Cramer cites insider buying at CHK as a good indication that natural gas is on the rise. He notes the bullish buying of CEO Aubrey McClendon, and comments, "He has historically been very astute with his buying." Natural gas currently trades at about $6 per million British units, and Cramer advises; "rather than think natural gas is a prelude to oil, I think oil is a prelude to natural gas."

Sony (SNE): Cramer believes this company has a potential gain when it introduces its $700 game and personal computer unit.

ATI (ATYT) and Advanced Micro Devices (AMD): Cramer trusts an analyst's prediction that AMD might be interested in ATI. He says that such claims are not made idly, because errors are costly. He also likes the stock, which "... has held up all day in a really doggy Nasdaq tape."

CBOT (BOT): Unlike NYSE Group (NYX), which is fighting the Nasdaq for listing, CBOT has pricing power and has raised fees by 20%. "It's good to be a monopoly," comments Cramer.
