    S&P 500 lost an estimated $2.9 trillion in market capitalization, the largest one-day loss of market value on record

  2. Research firm declares ‘end of the AI trade as we know it’ — and Asian tech stocks reflect the shift — MarketWatch

More: background

The “AI trade” refers to the surge of investor money into companies promising artificial‑intelligence products or services, which had driven rapid price gains in recent years. As those expectations have become harder to meet, analysts say absolute price appreciation is fading, pushing investors toward more speculative, longer‑term positions and relative‑value comparisons within the sector.
