Forward record, +20 sessions vs the TYPICAL universe stock (50% = no edge): beat it 30% of the time (CI 10.8–60.3%, n=10 events over 10 dates)

Median excess -5.2% · worst -16.4% · best +8.3%

Measured on 10 of 19 disclosed buy days (rest: same-session round trips, outside tracked price history, not yet matured, or overlapping adds).

Entry basis = the NEXT session's close. NSE publishes these disclosures after the close, so the deal-day price is one nobody holding this information could have paid.

On the old deal-day basis this read -1.4% — the +3.8% difference is the look-ahead, shown rather than quietly removed.

Recent disclosed buys: 2026-08-07 DIAMONDYD ₹32.3 cr; 2026-08-05 DIAMONDYD ₹25.5 cr; 2026-05-27 DIAMONDYD ₹14.7 cr
