Interpreting “SOXX index” as the iShares Semiconductor ETF (SOXX), the chart covers five complete calendar years, 2021–2025, of calendar-year-end trailing P/E ratios in turns (x). The five historical points are single-sourced from one Trefis page and are a reconstructed annual valuation series, not an official contemporaneous index series; five recent official iShares readings were collected only as a cross-source check.
| Year-end | Trailing P/E (x) | Basis | Source |

Source-validation note. Five official iShares product-page observations (August 2026) show current point-in-time portfolio P/E between 62.5x and 68.03x. They confirm the fund's identity and current metric but use a different methodology and level than the Trefis annual reconstruction, so they are kept off the chart. The Trefis series uses an aggregate method over profitable constituents applied to current SOXX holdings at current weights; negative-earning constituents fall outside that aggregate.
Data: 10 sourced rows — 5 calendar-year-end trailing P/E observations for the iShares Semiconductor ETF (SOXX), 2021–2025, single-sourced from one Trefis page (reconstructed with an aggregate method over profitable constituents at current holdings and weights), plus 5 official iShares point-in-time portfolio P/E checks from August 2026 shown only in the note. P/E is price divided by trailing earnings, in turns (x). No monthly precision is implied; this is not the official PHLX SOX index.
