Beyond Grantham: Politics and Investment Strategy

Jeremy Grantham, the chairman of GMO and one of the most respected investment minds of our era, believes strongly in what he describes as market “inefficiencies” within the “Presidential Cycle.”  He is referring to the fact that stock market returns are not distributed randomly across the four-year presidential election cycle, but rather are strongly skewed to favor the pre-election year.  Grantham believes – and I agree – that the evidence is incontrovertible:  the behavior of the political class over the election cycle systematically and profoundly effects the distribution of stock market returns.

Naturally such a conclusion is anathema to investment advisors who believe that market returns are random and that holding stocks continuously is the only way to harvest the superior long-term returns the market has to offer.

Yet, if Grantham is correct, it should be possible to develop a disciplined investment management strategy to exploit the inefficiencies within the election cycle.  Such a strategy could deliver high, risk-adjusted returns over the long term.

Let’s take a look at the election cycle and see if we can’t construct such a strategy.

The political “Sweet Spot”

Consider this fact:  Since 1933, the Dow Jones Industrial Average (with dividends) has been up during every pre-election year (year three of the presidential term).  The average return has been 17.1 percent plus dividends, about three times the average return of the other three years.  Every bear market (with the exception of the 1987 collapse) has occurred outside the pre-election year over this 78-year period.

I believe the cause of this remarkable market inefficiency is the predictable and rational response of the political class to mid-term Congressional elections.  The mid-term elections mark a turning point in the halls of Congress and in the White House.  Politicians, who devoted the first half of the presidential term to grand schemes for social change, must now prepare for the next presidential election.  This means a change in behavior.  All of a sudden, big spenders become fiscally conservative.  All talk of raising taxes is shelved.  Every incumbent pledges to cut the deficit and balance the budget.  Politicians promote business-friendly legislation.  In some cases, the Federal Reserve joins the party by juicing the economy with easy money and lower rates.  The Fed, like other Washington insiders, does not want to be blamed for a poor economy at election time.
Pres Election Cycle

Looking at the distribution of returns on a quarterly basis shows how powerful this effect is.  Note that the best quarter in the election cycle is the fourth quarter of the mid-term year – the quarter containing the mid-term elections.  This quarter, coupled with the four quarters of the pre-election year constitutes the market’s political “sweet spot.”
