www.marketwatch.comThe S&P 500 has been near a fresh record, with recent gains driven by hopes for de-escalation in the Iran conflict and lower oil prices. One report says the index rose about 1% and returned to positive territory for 2026, while CNBC also highlighted back-to-back gains tied to Iran peace-talk optimism.[1][8]
What is moving it

Recent market tone
