Is it redundant to hold both XLU and SSAC?

Out of every $100 split evenly between them, about $1 (half in each fund) buys identical positions. The rest is exposure only one of the two funds gives you: 2 names only in XLU, 1,610 only in SSAC. Half in each behaves like 64 equally weighted stocks, against 20 for XLU alone and 99 for SSAC alone. Whether that duplication is a problem depends on the mix you want; this is a description, not advice.

What is SSAC, next to XLU?

SSAC is iShares MSCI ACWI UCITS ETF (ISIN IE00B6R52259), an Irish-domiciled UCITS fund on the MSCI All Country World (ACWI) index. Next to XLU, 1.2% of the money is the same, spread over 29 companies both hold, as of October 14, 2026.

Does the XLU vs SSAC overlap apply to other tickers?

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 XLU vs IUSQ also overlaps 1.2%.

How is ETF overlap calculated here?

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.
