# US stocks close out their strongest first half in years

Wall Street is finishing the first half of 2026 with hefty gains, the major indexes rebounding from an early-year scare to post their best opening six months in years — though much of the advance has been powered by a narrow band of technology giants.

As the first half of 2026 draws to a close, U.S. stocks are riding high, recovering from a rocky start to deliver one of their strongest opening stretches in years.

## The numbers

The Dow Jones Industrial Average has gained more than 8 percent over the first six months of the year, on track for its best first half since 2021, [CNBC reported](https://www.cnbc.com/2026/06/29/stock-market-today-live-updates.html). The S&P 500 has risen by a similar margin, with the second quarter shaping up as its best since 2020. The technology-heavy Nasdaq has done better still, up around 11 percent. And smaller companies have led the way: the Russell 2000 has jumped more than 21 percent, heading for its best first half since 1991.

## A turbulent path

The gains belie a bumpy road. The year began with sharp swings, as a confrontation between the United States and Iran sent oil prices spiking and clouded the outlook for inflation and interest rates, prompting the Federal Reserve to turn more cautious about cutting rates. The mood shifted in the second quarter. As the conflict de-escalated and oil prices fell back, investors returned to the trade that has dominated the market for the past two years: artificial intelligence. Chipmakers and other technology firms tied to the AI build-out led the rally, with the semiconductor sector soaring this year.

## A narrow rally

For all the headline gains, the advance has been unusually concentrated. The handful of giant technology companies often called the "Magnificent Seven" now make up roughly 30 percent of the S&P 500's value, [according to Forbes](https://www.forbes.com/sites/investor-hub/article/sp-500-weight-mag-7-stocks-diversification-risk/) — meaning the broad index increasingly rises and falls with a few names. That concentration has prompted some investors to trim their exposure and has fueled a long-running debate about whether such lofty valuations can hold.

## What comes next

A strong first half is no guarantee of a strong second. Analysts caution that inflation, the path of interest rates and geopolitical flare-ups all remain live risks, and that a rally leaning so heavily on a small group of stocks is vulnerable if enthusiasm for AI cools. For now, though, the first half of 2026 will go into the books as a notably good one for investors — a rebound few would have predicted amid the turmoil of its opening weeks.
