Returns by Month

Gavin Chinn on September 28th, 2017

Happy Autumn! I love the Fall. The clear, crisp mornings and chilly nights. Also, the stock market drags itself out of the summer doldrums. But, is there really such a thing? Well, possibly.  Trading volumes in the summer months are definitely lighter than the rest of the year as people are off enjoying their vacations. But, more importantly to us, how does the market perform?

Taking a look at the S&P 500 returns by month from 1950 through 2014, September has the worst average annual return at -0.65%*. Conversely, December has the best average annual return at 1.54%*. There is not one clear answer as to why this is. And, as with most things in economics and financial markets, it’s probably a mix of many different elements. However, it is interesting to ponder.

From a money flow point of view, it makes sense that September is a down month. Very generally speaking, if money flowing into the market represents buying, then the summer months, with lighter volumes, would have less upward pressure.

Also, September 30th is the end of the fiscal year for many mutual funds. This means that they may be looking to sell losing positions in September for tax purposes and window dressing. Window dressing is when funds reduce or eliminate poor performing positions so that they don’t appear in their portfolio.

But what about the upside? December is not the most obvious candidate for best performer. With the Holidays in full swing, it’s hard to imagine that people are focusing too much on their investments. Between parties and presents and family, there are plenty of distractions. Perhaps it’s because of the optimism of the season, or the year end planning that takes place.

October is widely thought to be a tough month for investing. However, the numbers do not reflect that. With an average annual return of 1%**, it ranks solidly in the middle of the months. This, despite a drop of 16.94% in 2008^ (during the Great Recession) and a drop of 21.76% in 1987^ (Black Monday).

So, what does this all mean? Not a whole lot really. While September is the worst month on average, it is not always the worst month. And, it is impossible to say how any single month will do. Or any single day, week or year for that matter. What’s important is to have a portfolio that is allocated appropriately for you. Trying to time the market based on the months of the year would be foolish, in my opinion. Because, as always, your best chance for making money in the stock market is by investing for the long term.
