S&P 500 Semiconductor Index drops 15% by October 2026

Market overview

The Philadelphia Semiconductor Index has only been this overbought twice before: early 2000 and 1995. Given historical parallels to the 1999 tech bubble, a 15% correction by October 2026 aligns with prior bear market patterns triggered by extreme valuations.
