ISHARES RUSSELL 1000 GROWTH
2,662 institutions still hold ISHARES RUSSELL 1000 GROWTH as of Q2 2026. Tracked across SEC 13F-HR filings, with insider and 13D/G activity surfaced alongside.
iShares Russell 1000 Growth ETF (IWF, CUSIP 464287614) is a passive index vehicle with $80.8B of institutional 13F value at Q1 2026 — not an investable stock whose price action generates alpha narratives, but a reconstitution vehicle whose largest flows reflect institutional sleeve decisions at the equity-manager tier. As the benchmark ETF expressing U.S. large-cap growth (the Russell 1000 Growth index), IWF's institutional holder base is made up of active and passive managers using it as a beta expression tool, and the $80.8B figure represents the aggregate size of that beta-seeking sleeve. The smart-money read on IWF is not about the ETF's own economics but about the underlying Russell 1000 Growth index composition — whoever owns IWF is expressing a view on large-cap U.S. growth at the sleeve level, not at the individual-stock-valuation level at this security. Q/Q changes in IWF ownership across the holder universe are best read as rotations into or out of U.S. large-cap growth beta rather than as signals about any single company.
