Commentary: No statistical basis for Summer Rally

ANNANDALE, Va. (MarketWatch) - Monday's stock market action was particularly discouraging, with the Dow closing below its May 6 intra-day low of 9,870 -- the day of the infamous Flash Crash.
With that level now broken, investors face the prospect of the stock market decline picking up steam. The correction, which in Dow terms has already taken 12.4% off the market's level, is within shouting distance of becoming an official bear market--which would happen once the decline reaches at least 20%.
But wait! What about the Summer Rally?
Won't that save the day?
The answer from many of the investor advisers I track is a resounding "yes." Last week, for example, following the markets' Memorial Day holiday and the ceremonial beginning of summer, I began counting the number of times I saw reference to a "Summer Rally." There were so many I quickly lost track.
So for this column I decided to investigate what statistical support exists for the Summer Rally.
I have some bad news: There isn't any.
To be sure, there is no consensus among the Summer Rally's true believers about how precisely to define it. For purposes of my investigation, I looked at the market's gain from the end of May to its highest close during the subsequent three months -- through August 31.
I measured this gain using the Dow Jones Industrial Average /quotes/comstock/10w!i:dji/delayed (DJIA 9,816, -115.48, -1.16%) back to its creation in 1896. What I found might initially impress you: On average over the last 114 years, the Dow gained 5.3% from the end of May through its highest close over the next three months.
A three-month gain of that magnitude compounds out to an annualized equivalent of around 23%.
But there is less here than meets the eye. Measured this way, every season of the calendar can boast a rally of similar magnitude.
To show this, for each month of the calendar in addition to May, I calculated what the gain would be from the Dow's value at the end of that month to its highest close over the subsequent three months. It turns out that the average of those other months' gains is 5.3% -- just what it was for the so-called Summer Rally.
Another old wives' tale bites the dust.
How did investors and advisers come to believe in a Summer Rally in the first place? I have no idea, but I suspect that it might have had something to do with the extraordinary rally that occurred in the summer of 1932, in the depths of the Great Depression. The Dow nearly doubled during that year's summer's rally.
Without outlier years like that one, the Summer Rally loses even more statistical support.
Since 1940, for example, the average Dow gain from the end of May to its highest close over the next three months is just 4.0%. Eight of the other 11 months of the calendar sport higher average gains than this.
This discussion doesn't mean that the stock market won't rally at some point over the next three months, of course. No doubt it will. But its odds of doing so are not any greater just because the next three months come during the summer.
