Philadelphia Semiconductor Index Falls 5% as Nvidia Drops 3.3%

The Philadelphia Semiconductor Index fell 5% Friday, Nov. 13, as semiconductor shares sold off, with Nvidia down 3.3% and several peers posting sharper losses.

AMD fell 9.2%, while MRVL dropped 7.6%. AVGO and INTC each lost more than 5%. AMD's decline exceeded Nvidia's by 5.9 percentage points, and MRVL's was 4.3 points steeper. Both exact declines were also above the index's 5% loss.

All five individual stocks listed were lower alongside the index. Among the three exact company losses, Nvidia had the smallest decline and AMD the largest, with MRVL between them. The index's 5% fall was 1.7 percentage points deeper than Nvidia's decline, 2.6 points below MRVL's and 4.2 points below AMD's. That placed the index reading between Nvidia's and MRVL's losses, showing how semiconductor shares moved by different amounts during the selloff. The move matters for broader risk sentiment because it spans the semiconductor index and several individual chip stocks.
