XLI vs VUAA overlap

8.0% by weight, as of September 24, 2026: little overlap. 83 companies appear in both funds; they make up 100% of XLI and 8.0% of VUAA.

The largest shared positions are CAT, GE, GEV, RTX and DE. Ranked by the smaller of the two weights, which is the part you would own twice.

Out of every $100 split evenly between them, about $8 (half in each fund) buys identical positions. The rest is exposure only one of the two funds gives you: 0 names only in XLI, 420 only in VUAA. Half in each behaves like 77 equally weighted stocks, against 40 for XLI alone and 43 for VUAA alone. Whether that duplication is a problem depends on the mix you want; this is a description, not advice.

VUAA is Vanguard S&P 500 UCITS ETF (USD) Accumulating (ISIN IE00BFMXXD54), an Irish-domiciled UCITS fund on the S&P 500 index. Next to XLI, 8.0% of the money is the same, spread over 83 companies both hold, as of September 24, 2026.

Yes. VUAA also trades as VUAG (London, GBP), and VUSA (ISIN IE00B3XXRP09) is its distributing share class. Each is the same portfolio in another currency, on another exchange or paying its dividends out, so XLI vs VUAG also overlaps 8.0%.

For every company held by both funds we take the smaller of its two weights and add them up. The weights come from the full holdings files SPDR and Vanguard publish, not a top-10 sample, and companies are matched by their ISIN so share classes stay apart. Sector overlap applies the same rule to the issuers' sector labels; "behaves like N equally weighted stocks" is one over the sum of the squared weights.
