Wall Street wrapped up the first quarter of 2026 with modest gains, as investors weighed the latest economic data and positioned portfolios ahead of a packed April. With major indices holding near record highs, attention now turns to upcoming earnings and policy signals. ## Markets at a Glance U.S. equities ended the session slightly higher. The **S&P 500** advanced, with the index closing in positive territory and extending its quarterly winning streak. The **Nasdaq Composite** also ticked up, buoyed by strength in technology shares. The **Dow Jones Industrial Average** eked out a small gain, rounding out a steady quarter for blue chips. In the bond market, **Treasury yields** held steady, reflecting a wait-and-see stance as traders digested mixed economic signals. Commodities traded in a narrow range, with oil and gold prices showing little movement as geopolitical tensions remained muted. The **U.S. dollar index (DXY)** was largely unchanged, while **EUR/USD** hovered near recent levels, reflecting a balanced outlook between the Federal Reserve and European Central Bank policy paths. ## Key Movers Tech names led the way, with several large-cap software and semiconductor stocks outperforming as investors continued to favor growth sectors. Meanwhile, financials saw a muted session, with banks trading flat ahead of next week’s earnings reports. Energy shares were quiet, tracking sideways alongside crude oil prices. ETF flows remained robust, with continued interest in both U.S. and European-listed funds.
