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 56 of 102 and 52 of 74 equity positions matched to the QuantLogix stock universe — a lower bound, never an estimate.
QuantLogix's 5-factor engine currently reads Invesco QQQ Trust, Series 1 (QQQ) at 60/100 (buy) and State Street Technology Select Sector SPDR ETF (XLK) at 58/100 (buy). QQQ carries the stronger composite read by 2 points, led by options at 66/100. XLK's strongest leg is technical at 69/100. On trailing price performance, XLK leads over the last year (+39.6% vs +23.8% for QQQ). By filed portfolio weights, at least 42.5% of the two funds overlaps across 20 shared positions. Signals recompute throughout the trading day — the balance can shift with the tape.
