US stock investors are entering 2026 after a turbulent year that ultimately ended on a positive note. The S&P 500 index is set to finish 2025 up about 17%, marking the third consecutive year of double-digit gains. The technology-heavy Nasdaq Composite is poised for a 21% increase, while the Russell 2000, which tracks smaller companies, is roughly 12% higher.
Markets experienced significant volatility earlier in the year. In April, President Donald Trump announced sweeping tariffs on US trading partners, sending the S&P 500 to the brink of a bear market, defined as a drop of 20% from recent highs. Both the Nasdaq and Russell 2000 briefly fell into bear territory. Major indexes rebounded after the administration rolled back the steepest tariffs, easing investor concerns about a tariff-driven slowdown.
Strong corporate earnings have been a key driver of the market rally, analysts said. Parag Thatte, equity strategist at Deutsche Bank, noted that growth has begun broadening beyond tech giants, with average-sized companies posting stronger profits in the third quarter of 2025. The top five tech firms—Nvidia, Apple, Microsoft, Amazon, and Alphabet—account for almost 30% of the S&P 500, and enthusiasm for artificial intelligence investments has helped fuel their outperformance.
Still, analysts caution that some tech stocks may be overvalued and that a slowdown in AI-related growth could test the market’s momentum. “The rotation is already happening,” Thatte said, referring to investors gradually pivoting away from Big Tech. Vanguard analysts predict annualized returns of around 3.5% to 5.5% for US stocks over the next decade, lower than recent gains.
Safe-haven assets have also attracted investor attention this year. Geopolitical tensions, tariffs, and expectations of interest rate cuts boosted gold, which is on track for a nearly 70% annual gain. Bitcoin, however, is expected to close the year slightly lower after peaking in October.
Policy uncertainties add another layer of risk heading into 2026. Trump is expected to nominate a new Federal Reserve chair to succeed Jerome Powell, whose term ends in May. Paul Stanley, chief investment officer at Granite Bay Wealth Management, said the decision is “the big uncertainty” for investors, noting that Fed chair transitions often bring market volatility. The US labor market has also shown signs of weakness, with the unemployment rate rising to 4.6% in November from 4.4% in September.
Despite these concerns, analysts remain cautiously optimistic. Robert Edwards, chief investment officer at Edwards Asset Management, said the market continues to “climb the wall of worry,” with expectations that lower borrowing costs could support corporate earnings and higher stock prices.
Investors are heading into 2026 with strong momentum but remain alert to potential market swings from policy shifts, central bank leadership changes, and continued scrutiny of high-flying tech stocks.
