Dow Jones Ind. Average Performance by Political Alignment (1949-2015)

...we see a pattern that is contrary to popular belief. Under a Democrat, DJIA has performed better than under a Republican. DJIA has historically returned 10.0% under Democrats compared to 6.8% under a Republican executive. Congressional results are the opposite and much more dramatic. Republican Congresses since 1949 have yielded an average 15.3% gain in DJIA compared to a 6.1% return when Democrats have controlled the Hill.

Democrats in power of the two branches have produced an average DJIA gain of 7.4%, below the All Year average gain of 8.3%. With a Democratic President and a Republican Congress or a split Congress, DJIA has performed well averaging a 14.7% gain. The best scenario for all investors has been a Democrat in the White House and Republican control of Congress with average gains of 16.4%.
