The intriguing aspect of Berkshire Hathaway's energy holdings is that it only owns two stocks: Chevron (NYSE: CVX) and Occidental Petroleum (NYSE: OXY). For buy-and-hold investors like Warren Buffett, the natural expansion of the U.S. and global economy over time allows bank stocks, insurers, payment processors, and credit-rating agencies to expand in lockstep. No matter how poorly the U.S. economy performs or how high inflation flies, people still need to buy food, beverages, detergent, toothpaste, toilet paper, and a variety of other goods.
