Buffett's Berkshire Relies on P&G's Divestitures for Portfolio Pull

Lately, Procter & Gamble has been on a roll, picking up steam in October as the company also turned in a slight disappointment for investors with its quarterly report. Now, the company is disposing of disappointing detergent brands, as well as its Duracell subsidiary, preparing the battery maker for a spin-out into a separate company. With gains pushing up into the 10% range for P&G, the company may find itself relying on other M&A to prop up its portfolio's profits, more than the top line itself -- especially if an activist investor comes knocking. For now, P&G is a mainstay in Berkshire's portfolio.
