Seasonality Favors Bonds In September

September has averaged a -1% return for the S&P 500 Index since 1928*—the worst performance of any month, as noted in last week’s blog. However, although September has historically been a weak period for stocks, bonds have generally climbed, with the Bloomberg Barclays U.S. Aggregate Index gaining an average of 0.69% in September since its inception in 1976.

In recent weeks, the stock and bond market views diverged on the macro investing landscape. While stocks, as measured by the S&P 500, were back within one percent of record highs on August 29, 2017, bonds have taken a more somber view with the 10- year Treasury yield dropping to 2.13% on the same date, a level not seen since last November. Those differences will not be settled anytime soon; however, with stocks now entering a seasonally weak month, bonds may offer a temporary way to ride out the volatility.

Although we foresee an agreement being reached regarding the debt ceiling crisis, short-term Treasuries that mature near the end of September have shown a small increase in yields, indicating markets are pricing in at least some chance of a debate. In 2011, the newly elected Republican majority in Congress enacted a last-minute budget deal that avoided a government shutdown. That month, the Bloomberg Barclays U.S Aggregate Index returned 1.58%, while the S&P 500 returned -2.03%. For the full year of 2011, the S&P gained 2.11% on a total return basis, while the Bloomberg Barclays U.S. Aggregate closed the year with a 7.84% total return.

Budget and debt ceiling debates will be happening over the course of the next month, but it is too early to tell if they will take on similarities to the 2011 crisis. However even if there were no potential for political disagreements, there has been a historical seasonal pattern of weakness in stocks in September, and we continue to believe that bonds can offer a diversification benefit for portfolios, even at low yields.
