Financial markets prefer Republican presidents, right? Low taxes, reduced regulations and free markets are central to the Republican economic platform, and seemingly ideal to drive corporate earnings and stock prices higher. Yet, in looking back at the performance of the S&P 500 (“the market”) the results paint a different picture. Since 1926 the market has averaged nearly 15% a year when a Democrat sat in the Oval Office compared with a touch over 9% while a GOP was living in the White House. Even after removing Herbert Hoover from the study (a Republican president during the Great Depression when the market fell over 80%) the market performed better under the Dems.
