How I Invest
I feel that business is not a game of numbers but one of strategy. The world's greatest companies are run by dedicated leaders who focus their time on making long-term decisions to get an edge over their competition. And they develop a clear battle plan, understood and supported by the entire workforce, on how to achieve that strategy (Whole Foods, Southwest Airlines, and most of Berkshire's subsidiaries are great examples).
More than anything, I try to identify the sources and sustainability of a company's competitive advantage.
