XLE vs SSAC overlap

2.4% by weight, as of October 16, 2026: little overlap. 20 companies appear in both funds; they make up 99% of XLE and 2.4% of SSAC.

The largest shared positions are XOM, CVX, COP, MPC and VLO. 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 $2 (half in each fund) buys identical positions. The rest is exposure only one of the two funds gives you: 2 names only in XLE, 1,620 only in SSAC. Half in each behaves like 31 equally weighted stocks, against 9 for XLE alone and 102 for SSAC alone. Whether that duplication is a problem depends on the mix you want; this is a description, not advice.

SSAC is iShares MSCI ACWI UCITS ETF (ISIN IE00B6R52259), an Irish-domiciled UCITS fund on the MSCI All Country World (ACWI) index. Next to XLE, 2.4% of the money is the same, spread over 20 companies both hold, as of October 16, 2026.

Yes. SSAC also trades as ISAC (London, USD; Borsa Italiana, EUR) and IUSQ (Xetra, EUR). Each is the same portfolio in another currency, on another exchange or paying its dividends out, so XLE vs IUSQ also overlaps 2.4%.

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 iShares 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.
