Hey Charlie, thanks for bringing up your concerns about the performance discrepancy.
It's important to understand the difference between the Dow Jones Industrial Average (^DJI) and the SPDR Dow Jones Industrial Average ETF (DIA). The ^DJI is a price index, meaning it tracks the price movements of its constituent stocks without accounting for dividends. Conversely, DIA tracks these price movements and also captures all dividends paid by the stocks in the index. These dividend payments significantly contribute to the ETF's total return, in addition to the price movements. This is why DIA may show higher returns compared to ^DJI over extended periods.
Rest assured, our data analysis and reporting adhere to the highest industry standards. We continually monitor and evaluate our data for accuracy and reliability, ensuring we provide precise and insightful financial analysis.
Your attention to this detail is appreciated though, and I hope this clarifies your concerns.
The S&P and the Dow-Jones been price indexes since the day they were created. (The Dow-Jones index was created in 1896.) They will never, ever match the returns from and ETF or mutual fund that reports returns based on the payment of the underlying dividends. SPY has always outperformed the S&P index by the approximate amt of the annual dividends. And DIAhas always outperformed the DJ index by the amt of dividends paid by the underlying companies making up the index.
In theory, the ETFs should outperform the actual index by the amount of the annual dividends paid by the underlying price indexes. So if the S&P 500 stocks pay an approx 2% dividend, on avg, the ETF should outperform the actual index by about 2% plus any minuscule compounding of the dividends over that year and minus the expense ratio.
