State Street® SPDR® Dow Jones Industrial Average® ETF Trust

What this fund is

State Street® SPDR® Dow Jones Industrial Average® ETF Trust is an exchange-traded fund (ETF) from SPDR, traded under the ticker DIA (ISIN US78467X1090). 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 Dow Jones Industrial Average® index — mirroring that market instead of paying a manager to pick winners, which keeps costs low, and its largest holdings include GOLDMAN SACHS GROUP INC, CATERPILLAR INC and UNITEDHEALTH GROUP INC.

It holds around 31 positions (the ten largest ≈ 57.8%), spreading risk so no single holding decides your outcome. Its heaviest sectors are ~21% Financials and ~18.4% Industrials. 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 0.16% a year — about €16 a year on a €10,000 holding, taken automatically from the fund.

It holds the underlying investments directly (physical replication); it is domiciled in the United States and trades in USD. Its price has swung about 12.3% over the past year — a gauge of how much the value moves, not a judgement of quality. It launched in 1998. 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 SPDR.)
