Jim Cramer's Stop Trading! Buy Wal-Mart

Wal-Mart (WMT Quote) is going to $50, Jim Cramer said Thursday on CNBC's "Stop Trading!" segment.

Cramer said the fact that the stock of the Bentonville, Ark., retailer is only down a few pennies off Thursday's weak sales report shows that investors are "anticipating" better performance ahead. Cramer said the stock should go to the half-century mark from a recent $47.87, because management has shown it's serious about reforming the company's losing ways.

Cramer said all retail is a buy Thursday, because shares have come down far enough that all the negativity is pretty much priced in. Cramer said two big names worth looking at are J.C. Penney (JCP Quote) and Kohl's (KSS Quote).

Cramer also likes the railroads, saying activist hedge funds who are pushing for big leveraged buybacks and the like would be better off "picking on the underperforming companies." Cramer said the rails have been "the best-performing industrial group" and that making demands of a company such as CSX (CSX Quote) makes no sense, as "this isn't ABN Amro (ABN Quote) here."

"Go see a therapist," Cramer counseled.

Cramer likes a bullish call on Georgia Gulf (GGC Quote), up 7% at $18.88. He said the stock could go higher, as it should keep pace with recently hot PPG (PPG Quote). "Don't forget Olin (OLN Quote)," Cramer added.

Cramer also believes Apple (AAPL Quote) is headed to $120 from a recent $108.
