Warren Buffett's stock picks may be anything but flashy, but that's kind of the point. Given enough time, value performs. And in the case of Buffett's Berkshire Hathaway, it often outperforms. You'd be wise to borrow some of his ideas whenever possible.

Buffett's biggest purchase last quarter was in Occidental Petroleum. Berkshire Hathaway owns a whopping 27.25% of Occidental's outstanding shares, making it the largest shareholder by far in the company.
