Summary

US stocks kicked off 2026 with mixed performance on the first trading day, as the Dow Jones Industrial Average rose 0.6% and the S&P 500 gained 0.2%, while the Nasdaq Composite slipped slightly below flat. Semiconductor giants like Nvidia, AMD, and Micron saw notable gains, contrasting with declines in tech heavyweights like Tesla and Microsoft. After a strong 2025 with the S&P 500 up over 16% and Nasdaq over 20%, Wall Street remains optimistic for a fourth year of gains, though risks such as a potential AI slowdown, economic surprises, and political uncertainties tied to President Trump’s policies loom large. Precious metals like gold and silver held steady after their best yearly performance since 1979, and aluminum hit a significant price milestone. Attention now turns to key 2026 events, including the CES in Las Vegas, where AI will take center stage with presentations from Nvidia and AMD leaders. Meanwhile, the Federal Reserve’s direction, potential leadership changes, and interest rate decisions remain critical for investors, alongside a sputtering "Santa Claus rally" and broader market dynamics.
