Incorporating seasonal analysis into your portfolio management process is one way to mitigate risk and navigate through unexpected spikes in volatility during September. This can allow you to identify sectors and industries that may outperform the broad market, particularly during historically turbulent times.
Our latest analysis identified three sectors that showed a seasonal tendency to outperform the S&P 500 Index during September over the last 20 years—a month when the index has on average been lower by 0.6%, generating positive returns only 50% of the time. As we review the data, note that nonseasonal factors still influence performance and should not be ignored.
The table below highlights sectors’ average over- and under-performance versus the S&P 500 during September since 1997, as well as the top-performing industry groups over the same time period:
Looking at the table above, the healthcare and telecommunication services sectors have on average tended to exhibit the highest relative strength versus the index in September over the past 20 years. But, if you are looking for a more targeted strategy, there are potential diamonds in the rough within a few of more seasonally weak sectors. Among those, the software & services industry group stands out given the broader information technology sector has posted the worst relative performance during September over the period; and since this group encompasses a larger market cap and overall weighting within the S&P 500, it tends to be more significant than the other two.
Although the index has tended to post negative returns in September, seasonal analysis can help you navigate through volatile times. And given September’s historical tendency to be one of the most volatile months of the year, it could be a good time to consider implementing seasonal analysis.
