Here are some numbers to illustrate the consistency of this seasonal pattern:
- Since 1950, the S&P 500 Index has averaged a 0.54% decline in September, the worst of all 12 months.
- Over the past 20 years, September is still the worst month for stocks with an average decline of 0.6%, but January and June are close behind with average losses of 0.28% and 0.38%, respectively.
- Over the past 10 years, September is the only month when the S&P 500 averages a loss (0.35%).
- During midterm years the S&P 500 has averaged a 0.35% decline in September, though that ranks ninth and is better than January (-0.66%), May (-0.66%), and June (-1.76%).
- These negative seasonal effects are exacerbated when the index is down on a year-to-date basis heading into the month. When the S&P 500 has been down year to date through August (as it is this year), the index has averaged a decline of 3.4% in September (source: Bespoke Investment Group).
This isn’t a very uplifting message but consider that October is right around the corner and that month kicks off a string of some of the best months of the year for stocks. In fact, during midterm election years, the best three months of the year have been October, November, and December. The average midterm year gains for the S&P 500 over the final three months are 2.7%, 2.6%, and 1.2%, with gains 72%, 78%, and 67% of the time.
Stocks could likely hang in there for the next 24 days and then stage a strong fourth quarter rally. Based on history, that seems like a reasonable expectation.
Some welcomed relief from friday’s jobs report
Investors were ushered into their holiday weekends with a really nice jobs report. August payrolls increased by 315,000, right in line with consensus, while the unemployment rate ticked up slightly to 3.7%.
The labor market is moving in the right direction for policy makers. An uptick in unemployment along with a modest increase in the participation rate means that the labor market in August was less tight than it was in July. That’s what the Federal Reserve (Fed) wants to see.
We believe markets interpreted the jobs report correctly in rallying Friday morning given the broad-based gains in jobs as both goods-producing and services jobs rose in August. Although those early Friday gains didn’t hold, evidence of slightly less wage pressure in the report and some steepening of the U.S. Treasury 2 year-10 year yield curve were also encouraging. Odds of another 75 basis point rate hike from the Fed have come down but 50 vs. 75 is still a close call.
One caution flag waving right now is the rise in part-time workers who otherwise would be interested in full-time work. The economy is now employing more workers in temporary help services than ever before, and this could be a cause for concern. Businesses often begin cutting these jobs during periods of economic uncertainty and an increasingly large number of individuals in these roles is inherently unstable for the labor market.
Technical analysis perspective
Looking at the technicals for the S&P 500, the selling pressure has certainly been strong since Fed Chair Jerome Powell gave his “there is no pivot” speech at the Jackson Hole symposium.
In the weeks prior to the speech, there had been some important signals of potential technical strength looking forward. Among them was the S&P 500 retracing more than 50% of the bear market decline and the strong breadth reading with over 90% of S&P 500 stocks above their 50-day moving average. Both metrics have solid historical records as signals of better times ahead.
