Measure how much the funds overlap
The funds shared 23 equity issuers in that snapshot, with about 69.6% weighted overlap. For each shared issuer, take the smaller of its two reported fund weights and add those smaller weights together. This calculation uses the published portfolio weights, excludes cash and derivatives, and leaves the remaining weights on the same scale.
NVIDIA contributes 8.38 percentage points to that overlap because that was its lower weight. The difference between the funds’ NVIDIA weights still matters. If you hold both funds, multiply each NVIDIA weight by your allocation to that fund to estimate your combined exposure.
The same calculation using the funds’ June 30, 2026 SEC filings gives about 73.9% overlap. The two snapshots show why the date belongs beside the number.
