NASDAQ Today (Dec. 21, 2025): Nasdaq Composite Near 23,300 Ahead of Nasdaq-100 Rebalance, Fed Signals, and Nasdaq’s 23-Hour Trading Proposal
The Nasdaq is heading into Christmas week with a familiar late-December cocktail: holiday-thin liquidity, a “Santa Claus rally” watch, and the kind of tech-led price action that can look calm in the headline… right up until it isn’t. By the last close before the weekend, the Nasdaq Composite finished at 23,307.62, up 1.31% on Friday as large-cap tech rebounded, capping a week that still managed a gain despite early turbulence. Reuters That rebound matters because it re-centers attention on two things Nasdaq traders obsess over in late December: seasonality and rates.
