US equity markets surged to fresh all-time highs as peace optimism and a strong start to Q1 earnings season combined to deliver the market’s best two-week stretch since the post-Liberation Day recovery of 2025. The S&P 500 gained roughly +4.5% on the week and the Nasdaq surged +6.8%, its longest winning streak since 2009, clocking 12 consecutive positive sessions, while the Dow added +3.2%, with the S&P fully erasing all Iran war losses by Monday and closing at record highs mid-week.
