Major US equity markets started 2026 on a strong note, with the S&P 500, Nasdaq, and Dow Jones all posting impressive gains during the first full week of trading. The broad rally across all three benchmark indexes signals renewed investor confidence heading into the year, reflecting optimistic sentiment about economic prospects and corporate earnings potential. For crypto market participants monitoring traditional finance correlations, this upside momentum in equities could influence broader risk-on appetite and institutional capital flows into digital assets throughout the quarter.
