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 (2026-08-25 / 2026-08-28), computed on the 1044 of 2013 and 853 of 1311 equity positions matched to the QuantLogix stock universe — a lower bound, never an estimate.
QuantLogix's 5-factor engine currently reads iShares Russell 2000 ETF (IWM) at 53/100 (buy) and Vanguard Morningstar Small-Cap ETF (VB) at 40/100 (sell). IWM carries the stronger composite read by 13 points, led by microstructure at 68/100. VB's strongest leg is technical at 57/100. On trailing price performance, IWM leads over the last year (+15.4% vs +12.7% for VB). By filed portfolio weights, at least 16.1% of the two funds overlaps across 429 shared positions. Signals recompute throughout the trading day — the balance can shift with the tape.
