S&P 500 Jumps 5% in 4 Days, Marking 3rd Such Surge in 30 Years

3 articles · Updated · Yahoo Finance · Aug 7

Summary

  • The S&P 500 rose 5% in the four trading days ended Aug. 4, a rare burst that has occurred only three times in the past three decades.
  • Strong earnings from AI-linked heavyweights including Microsoft, Amazon and Palantir helped revive dip-buying, while signs of a possible U.S.-Iran de-escalation added support.
  • That rebound came after a multi-week pullback in chip and AI shares, even as hyperscalers still plan more than $700 billion in AI infrastructure spending this year.
  • History offers mixed signals: similar surges in 1999 and 2000 preceded painful dot-com losses, while the 2020 episode was followed by a longer rally before the 2022 bear market.
