USG Corp (NYSE:USG) (formerly US Gypsum) is a company makes dry wall for commercial and residential buildings. It recently emerged from bankruptcy. They overcame their asbestos issues and have paid off their settlement.
A couple of weeks ago, it was reported that Warren Buffett (NYSE:BRK.A) was buying USG heavily at under $50. In fact, he owns around 18% of the company now. The stock has been forming a bottom at $48 and with Cramer's endorsement after hours, it will definitely be up today.
I recommend you buy this stock as soon as possible. It is a rare occasion when Buffett buys so much of a particular company, so obviously he knows something that we don't.
