FUNDTracks the Dow Jones Industrial Average of large United States companies.
SPDR Dow Jones Industrial Average ETF Trust is an exchange traded fund. Tracks the Dow Jones Industrial Average of large United States companies. A fund like this holds many securities in one package, so an investor gets broad exposure to Dow Jones Industrial Average through a single holding. It trades on NYSE Arca like a stock during market hours. Funds charge ongoing fees and their value can rise or fall with the markets they track, so reading the fund documents is a good first step.
It follows the Dow Jones Industrial Average, one of the oldest and best known stock indexes. The Dow holds just 30 large US companies. The fund is often nicknamed Diamonds after its ticker.
The Dow is price weighted. That means a company with a higher share price has more pull on the index than one with a lower share price, no matter how big the company actually is. Most other major indexes weight by total company value. This is why the Dow can move differently from the S&P 500 on a given day.
With only 30 holdings, the fund is more concentrated than a broad market fund, but the companies are mature, large and well known. The fund pays dividends monthly, which some investors like. Compare its makeup to a broad S&P 500 fund so you know what you are choosing.
Why only 30 companies?
The Dow was built long ago as a simple snapshot of leading US companies. A committee picks the members.
What does price weighted mean?
The stocks with higher share prices count for more in the index.
Is the Dow the whole market?
No. It is a small slice of large companies.
