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 (2026-08-28 / 2026-08-28), computed on the 354 of 506 and 1813 of 3528 equity positions matched to the QuantLogix stock universe — a lower bound, never an estimate.
QuantLogix's 5-factor engine currently reads Vanguard S&P 500 ETF (VOO) at 54/100 (buy) and Vanguard Morningstar Total Stock Market ETF (VTI) at 63/100 (buy). VTI carries the stronger composite read by 9 points, led by microstructure at 64/100. VOO's strongest leg is technical at 59/100. On trailing price performance, VOO leads over the last year (+18.7% vs +18.6% for VTI). By filed portfolio weights, at least 55.5% of the two funds overlaps across 354 shared positions. Signals recompute throughout the trading day — the balance can shift with the tape.
