New York’s Nasdaq Composite fell more than 2% at the opening bell on Tuesday, June 23, 2026, as a global sell-off in major technology stocks accelerated. By midday, the index was down 409 points, or 1.6%, at 25,758, while the S&P 500 lost 1%, reversing part of the record gains built on artificial intelligence optimism. Investors shifted focus from broad AI narratives to evidence of concrete profit growth. Overseas markets were hit harder: South Korea’s KOSPI dropped 9.99%, triggering a 20‑minute trading halt, with Samsung Electronics and SK Hynix sliding over 12%. Japan’s Nikkei 225 fell nearly 4%, and Hong Kong’s Hang Seng declined almost 2%.
