How do you judge an ELSS tax saver fund's performance?

Judge an ELSS exactly like any diversified equity fund first — 3- and 5-year returns, risk-adjusted quality (Sharpe and Sortino), alpha against the benchmark, and cost — then add the lock-in lens: every rupee you put in is committed for three years, so the 3-year record is the minimum meaningful window. A muted 1-year number is noise; consistency across horizons is the signal.

The lock-in cuts both ways. It stops panic-selling in a crash, which quietly improves most investors' real returns. But don't keep feeding a laggard just because old units are locked — new SIP instalments can go to a stronger ELSS any time, while the old units simply serve out their three years. Star ratings from Value Research or Morningstar are useful corroboration, not a decision.

The current ELSS leaders by overall Smart Score — which already balances returns against risk and cost — are below. This is research, not investment advice.
