For 15 years, Eric Singer has been preaching the gospel that stocks do better when Congress is in recess. Now, he hopes to put his theory to good use with the Singer Congressional Fund, which intends to capitalize on those quiet non-legislative times in Washington, D.C. According to Bloomberg News, Singer, with research support from economists Michael Ferguson of the University of Cincinnati and Huge Douglas Witte of the University of Missouri-Columbia have studied the correlation between the markets and when Congress is in session and found that since 1897, 90% of the Dow Jones Industrial Average’s gains occurred when Congress was doing something other than their elected duties, creating the so-called “Congressional effect.” In fact, between 2000 and 2005, investors who kept out of the stock market while Congress was in session saw an annual return of 7%; those who stayed put realized a less than 1% annual gain. The effect, according to Singer, et al., has its roots in the theory that markets hate regulation, and the unpredictability of whether Congress will introduce regulation has its impact on the markets. Apparently, the effect is greater when Democrats, thought to be more regulation-prone, rule. Singer hasn’t shared yet how the funds will work, though Bloomberg News suggests that to make money, one would have to move in and out of the market between 15 and 20 times a year.
