Gridlock is Great for Stock Market Returns
"Since 1973, using the price of gold as a deflator (instead of the Consumer Price Index, which has suffered from style drift over the years) real, inflation-adjusted returns for the S&P 500 were a fabulous 15.3 percent gain in “gridlock” years, and a horrible 9.9 percent loss in years with unified government (see chart above). That’s a 25 percentage point difference.
The reason for this difference is simple: Unified governments spend far more, and more quickly, and expand regulation much more than split governments do. Programs sail through, the dollar is jeopardized, and investors seek real assets like gold to counteract the political risks of an activist government.
Based on the data, the ill effects of unified government apply to both Republican (a 7.7 percent loss) and Democrat (a loss of 11.5 percent) unified governments. The best was a split between a Republican Congress and Democratic President Clinton, which produced a whopping 32.8 percent real return.
President Reagan and a split Congress did pretty well too, with a 24.8 percent real return. Both President Reagan and Clinton did their best sustained work with a constraining Congress, or, to be more accurate, those Congresses did their best work with popular Presidents.
When it comes to split government and real returns, the right answer is “divided we stand, united we fall.”
