Analysis: U.S. Stock Futures Flat on December 28, 2025 Amid Holiday Trading

This analysis is based on the MarketWatch report [1] published on December 28, 2025, which noted U.S. stock futures were flat as investors aimed to end the year positively. The late holiday period (December 22–28) was marked by significantly reduced trading volumes: for example, Dow Jones volume dropped from 431.68M on December 22 to 288.78M on December 26 [0], typical of year-end holiday markets. This low liquidity likely contributed to the flat futures, as reduced participation limits price movements. Major U.S. indices closed with minor fluctuations on December 26: S&P 500 (-0.09%), NASDAQ Composite (-0.22%), Dow Jones (-0.00%) [0]. Additionally, Asian stocks opened muted on December 28, mirroring the U.S. trend of synchronized global muted activity amid holiday trading [0]. For 2026, there is a split in market sentiment: most analysts project high single-digit gains for the S&P 500 driven by earnings growth [0], while a minority warns of January 2026 volatility and potential bear market risks [0].
