Stocks in the United States are trading near all-time highs as investors rush to take advantage of the artificial intelligence revolution. The AI revolution offers transformative technology that promises to increase the country’s long-term growth rate through sustained productivity improvements. But these aren’t the only stocks making news.

Berkshire Hathaway announced a few days ago that it was buying, of all things, a homebuilder, Taylor Morrison. Berkshire Hathaway is controlled by perhaps the world’s greatest investor, Warren Buffett, who started with very little and became one of the wealthiest people on the planet. Buffett is famous for a simple investment philosophy: buy quality assets at reasonable prices and hold them for a very long time, decades rather than days. Berkshire Hathaway’s purchase of Taylor Morrison is a perfect example of that approach.
