Market Review: August and Outlook for September 2026

The stock market remained resilient throughout much of August, supported by strong corporate earnings and continued optimism surrounding technology and artificial intelligence. At the same time, investors faced uncertainty related to inflation, interest rates, bond yields and global events.

While these issues created some short-term swings, the major U.S. stock indexes remained positive for the year. As we move into September, investors will be watching new economic data and the Federal Reserve’s next interest-rate decision for clues about where the market may be headed.

August Market Activity

  • Major indexes remained strong: The S&P 500, Nasdaq and Dow continued to post positive year-to-date results. Technology stocks remained an important source of market growth, although performance varied across companies and industries.

  • Corporate earnings supported the market: Better-than-expected results from several large companies helped strengthen investor confidence. Strong earnings from technology and artificial-intelligence-related businesses were especially influential late in the month.

  • Inflation remained a concern: July inflation data released in August showed that prices were still rising faster than the Federal Reserve’s long-term target. Although inflation has improved in some areas, it remains high enough to create uncertainty about future interest-rate decisions.

  • Bond yields stayed elevated: Longer-term Treasury yields remained relatively high as investors considered persistent inflation, government borrowing and the direction of Federal Reserve policy. Higher yields can create pressure for stocks by increasing borrowing costs and making bonds more attractive to some investors.

  • Global events added volatility: Energy prices, trade concerns and geopolitical tensions continued to affect investor sentiment. Markets remained resilient overall, but headlines occasionally caused short-term shifts in stocks, bonds and commodities.

What to Expect in September

  • Employment and inflation reports will be important: Investors will receive updated information about the labor market, consumer prices and producer prices early in September. These reports will help shape expectations for economic growth and interest rates.

  • The Federal Reserve meets September 15–16: The Fed’s interest-rate decision will be one of the month’s most closely watched events. Investors will also pay close attention to the Fed’s comments about inflation and the possibility of additional rate changes later in the year.

  • Some market volatility is likely: September has several important economic and policy events on the calendar. Stocks and bonds may experience larger daily moves as investors react to each new report.

  • Corporate performance will remain in focus: Investors will continue evaluating company earnings and forecasts, especially within the technology sector. Broader earnings growth across more industries could provide additional support for the market.

  • Long-term strategy remains important: Short-term market movements can be difficult to predict. Maintaining a diversified portfolio and staying focused on long-term financial goals can help investors navigate periods of uncertainty.

Staying Focused on the Bigger Picture

September may bring new headlines and market fluctuations, but short-term volatility is a normal part of investing. Economic reports and Federal Reserve decisions can influence markets from week to week, while a sound investment strategy is generally built around goals measured over years.

Rather than reacting to every market move, investors should consider whether their portfolio remains aligned with their financial goals, time horizon and comfort with risk.
