Definition
Total Return Index (TRI)
A total return index measures performance assuming all dividends and other distributions are reinvested, capturing the full return earned by a holder rather than just price appreciation.
SEBI mandates that Indian mutual funds benchmark their schemes against the total return version of an index, not the price-return version, so that performance comparisons fairly include dividend income. The Nifty 50 TRI, for example, reinvests constituent dividends back into the index.
The gap between a TRI and the corresponding price index equals the reinvested dividend yield over time and compounds significantly over long horizons. Using TRI as the benchmark prevents active funds from looking artificially good by comparing against a dividend-stripped price index.
