- Sandisk and SK Hynix plunged as the Nasdaq declined in live intraday coverage, with TSMC simultaneously hitting a sell rule, per Investor's Business Daily.
- Nasdaq and S&P 500 futures pointed lower ahead of the July 16, 2026 session as Iran tensions and chip weakness kept investors on edge, with TSM, NVDA, NFLX, ATAI, and ASTS flagged as tickers in focus.
Why it matters: Chip-sector investors faced simultaneous pressure as Iran tensions drove broad semiconductor weakness across Sandisk and SK Hynix, while TSMC hit a sell rule on its own — layering company-specific selling on top of the macro-driven Nasdaq slide.
