Two funds head-to-head: live engine reads, trailing performance, and holdings overlap from SEC filings. An engine-read comparison — not a recommendation.
From each fund's SEC N-PORT filing (2026-08-24 / 2026-08-28), computed on the 257 of 368 and 94 of 147 equity positions matched to the QuantLogix stock universe — a lower bound, never an estimate.
QuantLogix's 5-factor engine currently reads iShares Russell 1000 Growth ETF (IWF) at 66/100 (buy) and Vanguard Morningstar Growth ETF (VUG) at 57/100 (buy). IWF carries the stronger composite read by 9 points, led by microstructure at 71/100. VUG's strongest leg is technical at 62/100. On trailing price performance, VUG leads over the last year (+13.2% vs +7.8% for IWF). By filed portfolio weights, at least 44.1% of the two funds overlaps across 68 shared positions. Signals recompute throughout the trading day — the balance can shift with the tape.
