FORMULA

The smaller weight is what really overlaps.

weighted overlap= Σ min(wA,i, wB,i)

Why not just count tickers? A 0.10% position and a 10% position count equally in a name match but do not create equal exposure.

Matching. Cash is excluded. MPLY–TOLL uses CUSIP matching where available; pairs involving MOAT use normalized tickers.

Not synchronized. The issuer dates differ by up to four calendar days. Holdings can change after those dates.

TOLL source caveat. Tema's page reports 40 holdings, while its August 21 download has 39 rows including cash—38 securities. This release preserves the discrepancy.

SHARED BY ALL THREE AVGO · AMAT · FTNT

3.31% minimum-weight overlap across all three dated portfolios.

COMMON QUESTIONS

Questions readers usually ask.

How much do MPLY and MOAT overlap?

Using issuer holdings dated August 25, 2026 for MPLY and August 24, 2026 for MOAT, 16 securities are shared and weighted overlap is approximately 11.66%. The figure is a Monopoly MOAT calculation: the smaller portfolio weight is summed for every shared security, with cash excluded.

How is weighted ETF overlap calculated?

For each security held by both funds, take the smaller of its two portfolio weights and add those minimum weights. This portfolio-intersection measure is more informative than counting matching ticker symbols alone.

Which stocks appear in MPLY, MOAT, and TOLL?

AVGO, AMAT, and FTNT appear in all three dated issuer snapshots used here. Their three-way minimum-weight overlap is approximately 3.31%.

Is ETF overlap necessarily bad?

No. Overlap describes shared exposure; it does not decide whether that exposure is suitable. Investors still need to assess mandate, valuation, concentration, fees, taxes, liquidity, and their own portfolio.
