Total Return Indexes and Dividend-Adjusted Prices

Summary

The document asks how a total return index differs from an adjusted price series. It describes a total return index as assuming dividends are reinvested and an adjusted price as accounting for the price drop around an ex-dividend date, so the investor’s price history reflects the dividend’s contribution. The question is whether those treatments amount to the same idea of dividend reinvestment.

No answer or worked comparison is included, so the document does not resolve the distinction. It raises a useful data interpretation issue for traders and researchers: dividend adjustments can affect historical returns, and the meaning of an adjusted series depends on how the adjustment is constructed. Readers should consult the index or data provider’s methodology before treating adjusted prices and a total return index as interchangeable. The text gives no examples, formulas, or evidence for a particular convention.

Key ideas

• The document contrasts dividend reinvestment in total return indexes with dividend adjustments in price series.
• It asks whether adjusted prices capture the same economic effect as reinvested dividends.
• No answer is provided, so the exact distinction remains unresolved.
• Historical return comparisons depend on understanding how each data series handles dividends.

I have a question regarding the difference between the total return index and adjusted price for the index.

Based on what I know...

- Total return index assumes dividend reinvestment.

- Adjusted price 'adjust' for dividend. If there arises a certain amount of dividend, then as an investor actually gets both 'dividend return' + 'price return', so the adjusted price should reflect the return part from dividend, wiping out the impact of ex-dividend.

If so, I think that two concepts are basically same in a sense that it has a concept of 'dividend reinvestment'. What's the difference behind those 2 concepts?
