The S&P 500 hit new all-time highs again in the third quarter as investors looked past a resurgence of COVID-19 cases in the U.S. and instead focused on the positive combination of a resilient economic recovery, ongoing historic support from the Federal Reserve, and strong corporate earnings. Market volatility did notably pick up during the final few weeks of September, however, reminding investors that the transition to a post-pandemic “new normal” isn’t always going to be smooth.
Stocks moved steadily higher to start the third quarter as the U.S. economy continued to return to pre-pandemic levels of activity while corporate earnings remained solid. To that point, second quarter earnings results, which were released in mid-to-late July, were stronger than expected and broadly did not show signs of the margin compression that some analysts feared might hurt corporate profitability. Additionally, at the July FOMC meeting, Fed Chair Powell reiterated that, despite economic progress, it was not yet time for the Fed to begin to reduce Quantitative Easing (QE), thereby ensuring the economy and markets would continue to enjoy full Fed support until late 2021. Those factors helped investors look past an increase in COVID-19 cases, as the S&P 500 hit a new all-time high in late July.
That positive momentum for markets continued in August, powered by similar factors: Positive corporate commentary, solid economic activity, and continued supportive Fed rhetoric. Those forces again combined to help markets look past a further increase in COVID-19 cases. Unlike during the COVID-19 waves of 2020 and early 2021, government authorities did not re-impose economic restrictions or lockdowns in response to rising case counts. Instead, most policy responses centered around mask mandates, and as such, the economic headwinds from rising COVID-19 cases were mild compared to previous episodes. Meanwhile, politics once again became a focus of the markets in August. The Senate passed a $3.5 trillion budget reconciliation bill that would be the framework for potential changes to tax rates, entitlements, and climate policy. But what passed in August merely set the stage for the looming policy battle once Congress returned from the summer recess. Given that, stocks were able to look past future policy risks and climb steadily higher throughout the month with the S&P 500 ending August essentially at all-time highs.
The market tone changed in September, however, as many of the positive factors that supported stocks earlier in the quarter began to fade. First, corporate commentary turned more cautious last month. Profit warnings that cited supply chain constraints and margin compression came from multiple industries, and that caused investors to become more concerned about the outlook for corporate earnings. Then, economic data from August showed that the rise in COVID-19 cases had weighed slightly on the economic recovery. Finally, after investors ignored the looming policy battle in August, politics once again became an influence on markets as Democrats unveiled new details on a $3.5 trillion spending and tax plan that included increases to the corporate tax, personal income taxes for high earners, and changes to capital gains and inheritance taxes. Those factors weighed on markets initially in September, but the volatility was compounded by the news that the second-largest property developer in China, Evergrande, was likely going to default on debt payments. Fear of potential financial market contagion hit stocks in late September and the S&P 500 suffered its first 5% pullback in nearly a year. Markets remained volatile into the end of the quarter as the Federal Reserve confirmed market expectations that it will begin to reduce Quantitative Easing before year-end, while Washington approached the looming deadline of a government shutdown with no extension in sight (although that was avoided in the last few days of the quarter). The S&P 500 finished September with moderate losses although the index still logged a positive return for the third quarter.
In sum, the market remained resilient in the third quarter, but the final few weeks of September served as a reminder to investors that markets will face the resolution of numerous macroeconomic unknowns in the fourth quarter, and while fundamentals remain decidedly positive, an increase in market volatility should be expected.
Third Quarter Performance Review
The last few days of the third quarter had a substantial impact on quarterly index returns. For the majority of the third quarter, the Nasdaq had solidly outperformed both the S&P 500 and the Dow Jones Industrial Average as investors continued a trend from the second quarter by moving to less economically sensitive large-cap tech shares. However, during the last week of the quarter, as global bond yields rose, there was heavy selling in tech shares as investors rotated into other market sectors. The Nasdaq still slightly outperformed the S&P 500 while the Dow Jones Industrial Average produced a negative return for the third quarter thanks to the late September sell-off.
By market capitalization, large-cap stocks outperformed small-cap stocks in the third quarter. In fact, small-cap stocks had a negative return for the quarter as rising COVID-19 cases, mixed economic data, and the prospects of eventually higher interest rates caused investors to favor large-cap stocks as the outlook for future economic growth became less certain.
From an investment-style standpoint, growth outperformed value in the third quarter, thanks to tech sector gains, although the amount of that outperformance shrunk considerably during the final week of the quarter as tech shares declined.
On a sector level, performance was more mixed than the previous two quarters as six of the 11 S&P 500 sectors realized positive returns in the third quarter, with financials leading the way . For much of the third quarter, the tech sector outperformed, but as bond yields rose in late September, financial stocks rallied on the prospect of higher interest rates and overtook tech as the best performing sector in the quarter. Healthcare also performed well, bolstered by strength in pharmaceutical stocks following more COVID-19 vaccine mandates and booster shot approvals.
Sector laggards included the industrials and the materials sectors, both of which finished with negative returns for the third quarter. Uncertainty surrounding the strength of the ongoing economic recovery in the face of higher COVID cases pressured industrials initially in the third quarter, as did a lack of passage of the $1 trillion bipartisan infrastructure bill. Meanwhile, the materials sector declined late in the third quarter on Chinese economic growth concerns following the Evergrande debt drama. Broadly speaking, cyclical sectors, those most sensitive to changes in economic growth, lagged more defensive sectors in the third quarter due to the uncertainty of the economic recovery in the face of the COVID wave in July and August.
Internationally, foreign markets declined in the third quarter. Emerging markets dropped sharply, initially on concerns that rising COVID-19 cases would derail the global recovery, but late in the quarter, emerging markets fell even further on Chinese growth worries that stemmed from the Evergrande debt issues. Foreign developed markets, meanwhile, declined modestly during the final few weeks of the quarter on general global growth concerns combined with potentially higher global interest rates.
