Understanding the 30-Year Average Return on the Dow Jones: Inflation-Adjusted vs Raw
Introduction
The Dow Jones Industrial Average (DJIA) is one of the most widely followed stock market indices in the United States. Over the long term, the performance of the DJIA can provide valuable insights into the health and growth of the U.S. economy. Understanding the average return on the Dow Jones, both inflation-adjusted and in raw terms, can help investors and analysts make informed decisions.
The Basics of DJIA Returns
The Dow Jones Industrial Average (DJIA) is composed of 30 large, actively traded blue-chip industrial stocks. Historically, the DJIA has been an important indicator of the U.S. economy's performance, as it represents the average price of the 30 component stocks, which are issued by some of the largest and most well-established companies in the country.
Inflation-Adjusted Returns vs Raw Returns
When comparing the performance of the DJIA over a 30-year period, it is essential to distinguish between inflation-adjusted returns and raw returns. The difference lies in how the growth is measured, and each method provides a different perspective on the value of investing in the DJIA.
Inflation-Adjusted Returns
When measuring the 30-year average return of the DJIA, inflation-adjusted returns provide a more accurate picture of the purchasing power of the investment. To account for inflation, we adjust the returns by subtracting the cost of living increases from the nominal returns. According to historical data, the average return for the U.S. DJIA over 30 years, adjusted for inflation, is 6.7%. This means that, on average, the DJIA's value increased by 6.7% per year when the rising cost of living is taken into account.
Raw Returns
On the other hand, raw returns do not adjust for inflation and are often used to compare the growth of the index over different periods. In raw terms, the 30-year average return for the DJIA is 9.7% if dividends are ignored and 12.8% if dividends are included and reinvested. These figures reflect the nominal gains in the DJIA's value over time without accounting for the erosion of purchasing power due to inflation.
Impact of Dividend Reinvestment
The choice to include dividends in the calculation of returns can significantly impact the overall value of the investment. Dividend reinvestment is a strategy where the dividends received are used to purchase more shares of the same stock or another stock in the same portfolio. Over time, this can lead to an increase in the total number of shares held, which can enhance the growth of the investment.
Potential Benefits of Dividend Reinvestment
By reinvesting dividends, investors can benefit from the power of compounding. The additional shares purchased with the dividends can generate more dividends in future periods, further contributing to the growth of their investment. In the context of the DJIA, if dividends are reinvested, the average return over 30 years increases to 9.7% from 6.7%. For a more substantial gain, reinvesting dividends can push the average return to 12.8%.
