SOXX · iShares Semiconductor ETF — SOXX at the wrapper layer

SOXX holdings — The iShares semiconductor wrapper, unpacked.

This panel deliberately stays in the package layer — AUM, expense ratio, top-10 concentration ladder, country and sub-sector breakdowns. The 30-name constituent map already lives on the preceding 'Inside the Index' panel and isn't repeated here.
