iShares S&P 500 Utilities Sector UCITS ETF
What this fund is
iShares S&P 500 Utilities Sector UCITS ETF is an exchange-traded fund (ETF) from iShares, traded under the ticker IUUS (ISIN IE00B4KBBD01). In a single purchase you get a diversified basket of holdings rather than a stake in just one business. At its core it is a focused, thematic fund: it concentrates on the utilities part of the market, so it lives or dies by that one area rather than the economy as a whole. Underneath, it is about owning small slices of companies, so you share in their growth when they do well — and their falls when they don't. It follows the S&P 500 index (passive investing): it tracks the market rather than relying on a manager, keeping running costs down, and its largest holdings include NEXTERA ENERGY INC, SOUTHERN and DUKE ENERGY CORP.
It holds around 36 positions (the ten largest ≈ 57.4%), spreading risk so no single holding decides your outcome. Geographically it leans ~100% United States. By industry it concentrates most in ~99.7% Utilities and ~0.2% Other. A focused fund like this is typically held as a smaller 'satellite' position around a broader core — a way to lean into one theme, not usually a portfolio's only holding. Its ongoing charge (TER) is 0.15% a year — about €15 a year on a €10,000 holding, taken automatically from the fund.
It is an accumulating share class: dividends are rolled straight back in, compounding your returns rather than landing in your account as cash. It holds the underlying investments directly (physical replication); it is domiciled in Ireland and UCITS-regulated, a European standard built to protect everyday investors and trades in USD. Its price has swung about 21.4% over the past year — a gauge of how much the value moves, not a judgement of quality. It launched in 2017. As with any investment, its value can go down as well as up, and past performance is not a guide to future results. (Fund data sourced from iShares.)
