What is SPDR Dow Jones Industrial Average ETF?
DIA tracks the Dow Jones Industrial Average, one of the oldest and most famous stock market indexes in the world, consisting of 30 blue-chip American companies. Unlike the S&P 500 which is weighted by market capitalization, the Dow is price-weighted, meaning higher-priced stocks have more influence. Beginners should know that DIA offers concentrated exposure to well-known industry leaders but is far less diversified than broader index funds.
DIA is managed by State Street Global Advisors and has been available since 1998. With $37.0B in assets under management, it's a well-established fund with strong institutional backing. The fund charges an expense ratio of 0.16%, which means for every $10,000 you invest, you pay approximately $16 per year in management fees.

How to Buy DIA — Step by Step
- Open a brokerage account — We recommend Fidelity, Charles Schwab, or Vanguard for ETF investing. All offer $0 commissions on ETF trades.
- Fund your account — Transfer money from your bank. You can start with as little as $1 if your broker offers fractional shares.
- Search for "DIA" — Use the search bar in your brokerage platform to find SPDR Dow Jones Industrial Average ETF.
- Place your order — Choose "Market Order" for simplicity or "Limit Order" if you want to set a specific price. Enter how many shares (or dollar amount) you want to buy.
- Set up automatic investing — Most brokers let you schedule recurring purchases (e.g., $100/month on the 1st). This is dollar cost averaging in action.
Dollar Cost Averaging Into DIA
Here's what consistent monthly investing could look like over time, assuming an average annual return of 8% (approximate historical stock market average):
| Monthly | 10 Years | 20 Years | 30 Years |
|---|---|---|---|
| $100/mo | $18,417 | $59,295 | $150,030 |
| $250/mo | $46,041 | $148,237 | $375,074 |
| $500/mo | $92,083 | $296,474 | $750,148 |
*Projections assume 8% average annual return with monthly compounding. Actual returns will vary. Past performance doesn't guarantee future results.
Fee impact: With DIA's expense ratio of 0.16%, a $10,000 investment would lose approximately $1,362 to fees over 20 years compared to a zero-fee investment. This is significant — consider whether the fund's strategy justifies these costs.
