Wall Street tech selloff deepens as chip index falls over 5%
At 11:36 a.m. ET, the Nasdaq was down 1.30%, the S&P 500 0.62% and the Dow 0.22%, with the Philadelphia Semiconductor Index down 5.4%.
What changed
Nasdaq -1.30%, S&P 500 -0.62%, Dow -0.22% at 11:36 a.m. ET; Philadelphia Semiconductor Index -5.4%.
Why it matters
High long-term yields reduce valuation support for duration-sensitive technology and can transmit to Indian IT and global risk appetite.
Who is affected
Global-equity investors, Indian IT investors, technology companies and portfolios with high growth-stock exposure.
Action required
Keep U.S. index levels labelled as intraday until the U.S. session closes; watch breadth and semiconductor leadership.
## What changed
U.S. equities were sharply weaker in technology-heavy areas on 18 August. At 11:36 a.m. ET, Reuters reported the Dow down 0.22% at 53,344.77, the S&P 500 down 0.62% at 7,696.91 and the Nasdaq down 1.30% at 26,298.98. The Philadelphia Semiconductor Index was down 5.4%, making chips the clearest pressure point.
The selloff came as long-term U.S. Treasury yields remained near multi-year highs and oil stayed elevated. Higher discount rates are particularly relevant for growth and AI-linked shares, where a larger proportion of expected value sits further in the future.
## Why it matters for India
Indian IT companies derive substantial revenue from the U.S., so weaker U.S. technology sentiment can affect domestic IT risk appetite even when the direct operating impact is limited. More broadly, high U.S. yields can pressure foreign flows into emerging markets and increase the cost of global capital.
## Finin2min takeaway
This is an intraday U.S. snapshot, not a Wall Street closing report. The key question is whether the semiconductor selloff broadens into the wider market or remains concentrated in high-duration technology.
**Watch next:** Fed minutes on 19 August and Nvidia’s upcoming quarterly results, both of which could reset expectations around rates and AI-linked valuations.
