Market Update | S&P 500 Posts Third Consecutive Year of Double-Digit Gains

Global equity markets posted solid gains for 2025 with the S&P 500 Index returning 17.9% and having a third consecutive year of double-digit gains. The index was essentially flat for December (+0.1%) as well as November, to fall short of a third year in a row of gains of 20% or more, which last occurred during the late 1990s during the internet boom. However, NASDAQ posted a third consecutive year of 20% gains, returning 20.4%. International stocks outpaced U.S. stocks with MSCI EAFE and MSCI Emerging Markets advancing 31.2% and 33.6%, respectively. Bond markets also rallied with the 10-year treasury yield falling from 4.55% at the beginning of the year to 4.17% at year end, which contributed to the Bloomberg Aggregate Bond Index returning 7.3% (yields fall; bond prices rise in value). The year 2025 was a great year for the markets, despite the headwinds of President Trump’s tariff policy, the longest government shutdown in U.S. history, rising unemployment and lingering geopolitical risks. Fueling the market gains was a U.S. economy growing much stronger than anticipated for the second and third quarters, artificial intelligence (AI) showing productivity gains, tariffs not materially impacting inflation as much as economists feared, three Federal funds interest rate cuts and corporate profits soaring above analyst expectations.

Market Return Indexes Dec 2025 YTD 2025 2024
Dow Jones Industrial Average 0.9% 14.9% 15.0%
S&P 500 0.1% 17.9% 25.0%
NASDAQ (price change) -0.5% 20.4% 28.6%
MSCI Eur. Australasia Far East (EAFE) 3.0% 31.2% 3.8%
MSCI Emerging Markets 3.0% 33.6% 7.5%
Bloomberg High Yield 0.6% 8.6% 8.2%
Bloomberg U.S. Aggregate Bond -0.2% 7.3% 1.3%
Yield Data (Month End) Dec 2025 Nov 2025 Oct 2025
U.S. 10-Year Treasury Yield 4.17% 4.02% 4.11%


The U.S. economy as measured by U.S. Gross Domestic Product (GDP) grew at 4.3% for Q3 2025 (year-over-year), much better than economist consensus forecasts with the U.S. Bureau of Economic Analysis releasing the initial estimate on December 23. Several key economic data releases were delayed due to the government shutdown. An updated estimate for Q3, including by industry, is scheduled for release on January 22, 2026. U.S. GDP growth for Q3 was substantially higher than Q2 (at 3.8%) which had been revised several times higher from its initial estimate of 3%. The Q3 GDP reading was the strongest since Q3 of 2023.

AI advancements accelerated in 2025 across business segments with the expectations that AI could further propel productivity gains that the internet exhibited during the late 1990s. Productivity gains can help businesses do more with less, leading to improved bottom line results. AI productivity gains in 2025 include faster task completion in software development (e.g., coding and writing), healthcare diagnostics (e.g., X-rays, MRIs, automating administrative tasks to free up clinicians) and scientific (e.g., accelerated medical research). While the largest gains were in the Communication Services and Technology sectors more tied to AI, other industries such as Basic Materials, Industrials and Financial Services prospered indicating the market rally was more widespread across S&P 500 sectors than prior years. While market valuations are stretched due to AI optimism, P/E ratios were much higher prior to the internet bubble that burst in March 2000.

Effects on inflation and unemployment were not as bad as feared back in early April when President Trump announced his tariff policy. The President’s 2025 tariffs went beyond the tariffs from his first term and even more than the Smoot-Hawley Act of 1930. The average tariff on U.S. imports rose from 2% to 18% according to Yale Budget Lab, the highest level since the 1930s. However, the Consumer Price Index (CPI) was essentially unchanged from a year ago, ending November at 2.7%, the same level as a year ago. Unemployment slightly rose from 4.1% at the end of 2024 to 4.6% in November. Part of the increase in unemployment was due to Federal job cuts (over 200k jobs this year). With the labor market slowing throughout the year, the Federal Reserve cut interest rates three times between September and December 2025 with the rate between 3.5% and 3.75% at year-end. The expected rate a year from now, according to Federal Funds Rate futures is 3.0% to 3.25%, or another half percent easing.

According to FactSet, the S&P 500 reported earnings growth of about 13.4% to 14% for Q3 2025, which was significantly above analyst estimates of 7% to 8% growth. The S&P 500 reported its fourth consecutive quarter of double-digit earnings growth. Based on recent FactSet data (as of late December 2025), the estimated earnings growth for S&P 500 companies was 8.3% for Q4 2025 and 15% for the calendar year of 2026. The 8.3% earnings growth was revised upwards from 7.2% at the start of the fourth quarter and would mark the 10th consecutive quarter of growth for the index. The 15% estimate for 2026 was well above the 10-year average of 8.6% and could mark the third consecutive year of double-digit earnings growth.

Despite the mentioned headwinds, the economy and markets continued to deliver above expectations. For 2026, it may be more challenging for the U.S. equity markets to extend their rally. A 15% earnings growth expectation is lofty, and U.S. stocks are trading at higher price/earnings multiples compared to historical measures. While tariffs have not materially impacted inflation, some economists fear they have been delayed as businesses have not fully raised prices or fully depleted their pre-tariff inventories. Tariff policy remains volatile with the U.S. needing to iron out agreements with China and India and ongoing disputes with Canada and Mexico. The Fed funds rate cuts will need to help stabilize the job market from further weakening, otherwise concerns over a recession could build. President Trump is expected to hire a new Federal Reserve Chairman to replace Jerome Powell which could cause market speculation on the direction of the economy in 2026 and beyond. Finally, 2026 will mark midterm elections, which have been associated with heightened volatility and lower returns (essentially flat historically) in the 12 months prior to midterms. The good news is that since 1950, the S&P 500 has risen an average of 16% in the 12 months following the vote and have not had a negative return since 1939! Happy Holidays and New Year to everyone!
