How this was measured

Events. Every NSE board meeting that considered financial results, on its real date (NSE filings).

Entry. The close of the first trading day after the meeting, because results often arrive after market hours.

Strong results. Sales up at least 10% and profit up at least 15% on the same period a year earlier, with a profit. Uptrend: close above its 200-day average at entry. Weak: a loss, or profit down 15% or more.

Return. Split-adjusted price change minus Nifty 50 over the same trading days. Hover a number for the median, the share of events that beat the index, and the t-statistic.

Limits. No trading costs or slippage, events overlap in time, and most events are smaller companies while the benchmark is large caps, so "all events" can sit below zero. Quarterly figures exist for about three years; annual results reach further back. This shows an average reaction, not a strategy anyone should follow. Not investment advice.

Data: NSE and BSE daily reports, company filings. Numbers only, not investment advice, not a SEBI-registered research service.Updated 2026-10-03
