Warren Buffett's Top Oil Stock Picks for June

Warren Buffett has always been a contrarian investor. His company, Berkshire Hathaway, is known for investing in unloved industries and out-of-the-way locations. In June, Buffett's top stock picks include oil giants Chevron and Occidental Petroleum.Berkshire Hathaway owns nearly 123 million shares of Chevron, making it one of its largest holdings. Despite underperforming the S&P 500 and other energy stocks recently, Chevron has strong growth potential. The company's upcoming deal to acquire Hess could significantly increase its free cash flow and production outlook.On the other hand, Berkshire Hathaway also holds over 248 million shares of Occidental Petroleum. Occidental's acquisition of CrownRock last year is expected to boost its annual free cash flow significantly. In addition, the company has several other growth catalysts in place, including increasing cash distributions from investments and investments in its chemicals business.Both Chevron and Occidental Petroleum have strong businesses that generate significant free cash flow, making them attractive investments. Buffett's contrarian bet on oil stocks could pay off in the long run, providing investors with strong total returns.
