Prediction markets put the probability at 32%: Will the S&P 500 have the best performance in 2026. Currently, markets are divided (32% YES, 68% NO). Stock futures are little changed after the S&P 500 hits a record to wrap April's trading: Live updates.
The S&P 500 closed April 2026 at a record high, capping its strongest monthly gain since 2020 with a 10.4% advance, while the Nasdaq Composite climbed 15.3% over the same stretch. Both benchmarks notched fresh intraday and closing records on April 30, with futures little changed into the May 1 session as investors digested the month's earnings deluge. Whether the S&P 500 have the best performance in 2026 against global peers hinges on the durability of this rally, which followed receding worst-case fears tied to the Iran oil shock. [CNBC, Apr 30]
Corporate profits are the rally's load-bearing pillar. With more than two-thirds of first-quarter results in, S&P 500 blended earnings growth stands at 27.1% year-over-year, materially above the 13.2% consensus at quarter-end and tracking the index's strongest quarterly print in more than four years. Big Tech set the tone last week, and a second wave of 128 S&P 500 companies is scheduled to report in the week beginning May 4. The question of whether the S&P 500 have the best performance in the developed-market complex this year is being underwritten by margin resilience rather than multiple expansion. [Kitco, May 6]
Risk factors remain live. On May 1, the Dow traded flat and the S&P 500 and Nasdaq trimmed gains after President Trump threatened higher tariffs on European vehicles, reintroducing trade-policy volatility into a tape that had absorbed the Middle East peace overture earlier in April. Oil futures, with July Brent up 1.11% on May 1, remain a swing variable for inflation expectations and the Fed's policy path. The last time the S&P 500 posted a 10%+ April, in 2020, the index closed the year up roughly 16% — a base rate investors are weighing against current tariff and energy crosscurrents.
