The S&P 500 has delivered roughly 13% annualized returns over the past decade, one of the strongest bull runs in modern history. Berkshire Hathaway (NYSE:BRK-A)(NYSE:BRK-B), long the gold standard for patient capital, has matched that pace with about 13% annually over the same stretch. Impressive numbers for most investors. Yet both look like amateur hour next to the woman still serving out her final term in Congress: Nancy Pelosi.
