iShares MSCI USA Mid-Cap Equal Weight UCITS ETF

What this fund is

iShares MSCI USA Mid-Cap Equal Weight UCITS ETF is an exchange-traded fund (ETF) from iShares, traded under the ticker IUSZ (ISIN IE00BD1F4K20). One trade buys a whole basket of holdings, so your money is spread out instead of riding on a single company. In plain terms 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, spread across its target market. It passively tracks the MSCI USA index — mirroring that market instead of paying a manager to pick winners, which keeps costs low, and its largest holdings include ASTERA LABS INC, OKTA INC CLASS A and AXON ENTERPRISE INC. It holds around 302 positions (the ten largest ≈ 4.8%), spreading risk so no single holding decides your outcome.

By geography it is weighted towards ~99.8% United States, ~0.1% Ireland and ~0% United Kingdom. Its heaviest sectors are ~18.2% Industrials and ~15.1% Financials. It is commonly used to tilt a portfolio towards one market, usually alongside broader, more global funds rather than on its own. Its ongoing charge (TER) is 0.2% a year — about €20 a year on a €10,000 holding, taken automatically from the fund. Income such as dividends is automatically reinvested inside the fund (an accumulating share class), so returns compound without you doing anything.

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 45.5% over the past year, which describes how much its price tends to move rather than whether it is good. It launched in 2016. Like any investment, it can lose value as well as gain, and what it did before does not predict what it will do next. (Fund data sourced from iShares.)
