Every number here is computed by fixed rules written down before the results were looked at. Nothing is written by an AI model.
How unusual: each driver's latest move is ranked against every move of the same kind since 2016. A move in the top or bottom fifth counts as unusual; anything else is ordinary and gets no comparison.
What happened before: for an unusual move, we find past dates with a move in the same fifth and the same direction. Dates close together count once, and no two cases share any days of their outcome window.
We then measure the Nifty 50's change from the first trading day after each past move became public, over 21, 63 and 126 trading days (about one, three and six months).
Every result shows the number of past cases, their middle value (median), the middle half and the full range, and the base rate: the Nifty 50's median change over every period of the same length since 2016.
Fewer than 6 past cases: no figures are shown. More than half the cases in one year: a caution names that year.
Data: market prices from Yahoo Finance, US rates from the US Treasury and the New York Fed, policy rates from the RBI and the Bank for International Settlements, inflation from the OECD, foreign investment from NSDL. Each figure names its own source and date.
Limits: our Nifty 50 history starts in October 2016, so every record covers about ten years. Some older inflation figures are today's revised values, not the first published ones.
Past patterns are a record, not a prediction.

- Basis point
- One hundredth of a percentage point. A rate moving from 5.25% to 5.50% has moved 25 basis points.
- Percentage point
- The plain difference between two percentages: inflation going from 4% to 5% is a 1 percentage point rise.
- Percentile
- Where a reading sits within its own history, from 0 (the lowest ever seen) to 100 (the highest). The 90th percentile means higher than 90% of past readings.
- Median
- The middle value: half of the past cases were above it and half below.
- Middle half
- The range covering the middle 50% of past cases, leaving out the top and bottom quarter.
- Base rate
- What the Nifty 50 did over every period of the same length since 2016, whatever else was going on. It is the yardstick for any single pattern.
- Trading day
- A day the Indian stock market was open. About 21 trading days make a month.
- Log change
- A way of measuring percentage moves that adds up cleanly over time. For small moves it is almost the same as a plain percentage.
