U.S. Tech and AI Stocks Plunge in "Black Tuesday" Rout; Micron and SanDisk Lead Declines

On Tuesday, June 24, U.S. equity markets experienced a significant downturn characterized as a "Black Tuesday" rout for the technology sector, according to market data reported by ChainThink. The Nasdaq Composite led the decline, falling 2.2%, while the S&P 500 and Dow Jones Industrial Average dropped 1.4% and 0.09%, respectively. The sell-off was particularly acute among AI-linked and storage companies, with SanDisk (SNDK) and Micron (MU) both plunging more than 13%. Optical-module providers such as Applied Optoelectronics (AAOI) and Coherent (COHR) also saw double-digit losses. Large-cap tech leaders, including NVIDIA and Tesla, faced substantial pressure, while the crypto-related sector followed suit as MicroStrategy (MSTR) and Coinbase (COIN) recorded losses exceeding 4%. This broad-based retreat reflects heightened volatility in high-growth sectors.
