The S&P 500 closed out Q2 2026 with a 14% quarterly gain, its strongest three-month run since 2020, adding over $8 trillion in total market value. Futures ticked up another 0.1% on the final day of the quarter as investors locked in gains. The rally's engine was concentrated in artificial intelligence, with Wells Fargo projecting 22% earnings growth for Q2 and the top 20 S&P 500 stocks delivering triple-digit returns in the first half of the year alone.
A 14% quarterly gain means most diversified equity portfolios had a strong quarter, but the concentration in AI-linked names signals that passive index holders rode the wave unevenly. If Wells Fargo's 22% earnings growth estimate holds when Q2 results arrive, it would provide fundamental validation for stretched valuations — if it misses, the quarter's gains become vulnerable to a sharp reversal. Investors overweight broad indices benefited; those underweight tech and AI significantly lagged.
Mid-July: Q2 earnings season kicks off with major bank reports. Late July: Big Tech earnings (Meta, Alphabet, Microsoft, Amazon). August 13: CPI inflation report for July. July 29-30: Next FOMC rate decision.
