2025 Global Stock Performance & 2026 U.S. Pre-Market Opening Analysis

This report analyzes market dynamics on January 2, 2026, the first trading day of the year following U.S. markets’ closure for New Year’s Day. U.S. pre-market futures show broad gains, with Nasdaq Composite futures leading (+1.01%) due to AI innovation announcements at CES 2026, specifically ADATA Technology’s AI-focused memory module releases [2].

2025 was a standout year for global stocks: Hong Kong’s Hang Seng Index rose 28% (its best year since 2017) and South Korea’s Kospi surged over 75% (best since 1999), driven by local AI tech booms rather than just the 6.65% decline in the WSJ Dollar Index [3][4]. A Wall Street Journal analysis confirms these gains stemmed from regional growth factors, not merely currency tailwinds [1].

U.S. indices also closed 2025 with double-digit gains for the third consecutive year (S&P 500 +16%, Dow Jones Industrial Average +13%, Nasdaq Composite +20%), despite ending with four straight down sessions [5].

1. Global Stock Leadership Shift
   : Asia’s tech-heavy markets (Hang Seng, Kospi) emerged as 2025 leaders, with AI as the primary driver—demonstrating that currency movements (dollar weakness) were not the sole catalyst for foreign share gains.
2. CES 2026 AI Momentum
   : Pre-market Nasdaq strength highlights ongoing investor enthusiasm for AI innovations, indicating the sector’s potential to drive short-term market performance.
3. U.S. Market Resilience

  : Potential regulatory shifts for AI technologies could impact tech sector performance.
• Fed Policy Volatility
  : Market pricing for 2-3 Fed rate cuts in 2026 introduces macroeconomic uncertainty.
• Sustainability of Asia’s Momentum
