The finding
Across 6,050 results filings, the median share was -1.48% over the next 30 days, and only 43.4% ended higher. Results are the most-watched filing a company makes, and in this dataset they are followed by drift downwards — while order wins and mergers drift up. This is a record of what happened, not a prediction of what will.
Every tracked filing type, 30 days on

How this is measured
- Source. BSE's official daily bhavcopy — the exchange's own end-of-day record for every listed scrip, not a third-party feed.
- Anchor. The close of the first trading day on or after the filing. The initial move on the announcement is already in that starting price, so these figures show the drift afterwards.
- One observation per filing. Never several days from the same filing, which would let heavily-traded names count more than once.
- Median, not average. One extreme microcap cannot move a published figure. The bar shows the interquartile range so the spread is visible.
- Exclusions. Windows containing a bonus issue or stock split (a 1:2 split reads as −50%), illiquid counters that barely traded, and changes beyond ±150%.
- Filing types. Only discrete events with an unambiguous direction. Categories that mix opposite events — a rating upgrade with a downgrade, a favourable court order with a penalty — are excluded, because a single median across opposites means nothing at any sample size.
- Minimum sample. Nothing below 100 observations is published, enforced in the database itself.
