Nasdaq-100 futures reached a new all-time high of 27,830 today, leading a broad-market rally as tech earnings continue to drive investor sentiment. Major technology firms delivered strong quarterly results and forward guidance, providing significant upside momentum for the growth-heavy index. While the S&P 500 and Russell 2000 futures also posted record highs during the session, the Dow Jones Industrial Average futures lagged behind as earnings-driven rotation impacted the price action of various blue-chip components. Despite a slight retracement from intraday highs that saw the market up over 1.0%, the Nasdaq-100 remains the standout performer for the week. Market dynamics show a clear preference for the big tech sector, which exerts a larger influence on the Nasdaq-100 compared to other U.S. benchmarks. Dan Deming explores the earnings-led strength and the divergence between the major indices as the trading week concludes.
