Dow Jones| Nasdaq | S&P 500 | US Stock Market Today | Live: US stock futures slip as chip stocks drag; Netflix tumbles

Wall Street futures declined sharply as semiconductor stocks extended losses, with Nvidia and Intel leading the slide and the Philadelphia Semiconductor index hovering near a two-month low. Netflix tumbled close to 10% after issuing a weaker-than-expected forecast for the third quarter, overshadowing strong earnings from TSMC and ASML. Escalating US-Iran tensions, concerns over Gulf energy flows, and US-China political friction pushed the CBOE Volatility Index to a one-week high, leaving major US indexes positioned for weekly losses.
