Its record
Growth of one rupee after costs, before tax, on a log scale, beside its benchmark: equal weight across the same eligible sectors, rebalanced each month. The benchmark holds the assets the rule chooses from but never switches, so the gap is what the rule's timing added or cost. The marks show when the rule was published and when it entered this library; only the stretch after the second mark is free of hindsight. Deciding on a different day of the month would have changed its return before tax from 10.9% to 15.3% a year.
