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 (2026-07-13 / 2026-05-28), computed on the 982 of 1977 and 849 of 1312 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 70/100 (strong buy) and Vanguard Morningstar Small-Cap ETF (VB) at 67/100 (buy). IWM carries the stronger composite read by 3 points, led by microstructure at 72/100. VB's strongest leg is technical at 74/100. On trailing price performance, IWM leads over the last year (+33.9% vs +25.2% for VB). By filed portfolio weights, at least 18.4% of the two funds overlaps across 425 shared positions. Signals recompute throughout the trading day — the balance can shift with the tape.
