Nifty 500 contribution today: which stocks and sectors moved the index
The Nifty 500 contribution table (IMAP) shows which sectors and stocks actually moved the Nifty 500 today, and by how much. A stock's contribution is its weight in the index times its move today, divided by 100, in percentage points of the index's move, so a heavy stock that rises a little can count for more than a small one that rises a lot. A heatmap tells you what is up and down; contribution tells you what moved the index.
At a glance
Measures
Each stock's weight in the index × its move today ÷ 100
Unit
Percentage points of the Nifty 500's % move (× the index level ÷ 100 for index points)
Rows
Sectors, then sub-sectors, then stocks, largest contribution first
Weights
Free-float market capitalisation share, rebuilt on the 1st of each month
Updates
Sector rows every 10 seconds in market hours
Where
On a computer; on a phone this address shows the heatmap

The columns
Impact
The contribution itself: positive added to the Nifty 500's move today, negative took away. A sector row adds up its stocks, and rows are sorted by the size of their contribution.
Return and weight
Return is the weighted average move of the row's stocks, so it always points the same way as Impact. Weight is the row's share of the Nifty 500.
Min, max, count, % up, % down
The weakest and strongest stock's move in the row, how many stocks it holds, and the share of them rising and falling today.
Stock rows
Open a row down to single stocks for each one's % change, contribution, last price, volume and weight in the index.
How contribution is worked out
Weights
Each stock's weight is its free-float market capitalisation as a share of the index's total.
Percentage points, not index points
Contributions are in percentage points of the index's % move: if the Nifty 500 is up 1% and a stock's contribution is +0.20, that stock accounts for 0.20 of that 1%. To turn it into index points, multiply by the index's level and divide by 100: at 25,000, +0.20 is about 50 points.
Live, and where
On a computer, the sector rows refresh every 10 seconds in market hours; a sector or sub-sector you open shows its stocks as of when you opened it. On a phone, this address shows the heatmap of the same stocks.
The same stocks as a heatmap
To see the same stocks as tiles coloured by today’s move, open the Nifty 500 heatmap.
How much each sector and stock added to or took away from the Nifty 500's move today, weighted by its share of the index. It answers which stocks moved the index, rather than which stocks went up.
Which stocks contributed most to the Nifty 500 today?
Open the table and read the Impact column: rows are sorted by the size of their contribution, so the top rows moved the Nifty 500 most. Open a sector to see its stocks.
How is a stock's contribution to the Nifty 500 calculated?
Its weight in the index (its free-float market capitalisation as a share of the index's total) times its move today, divided by 100. A sector's contribution is the sum of its stocks'.
Is contribution shown in index points?
No, in percentage points of the index's % move. To convert, multiply a contribution by the index's level and divide by 100: at 25,000, a contribution of +0.20 is about 50 index points.
What is IMAP?
IMAP is Alphave's index contribution table: it maps an index's move today onto the sectors, sub-sectors and stocks that made it, using each stock's weight in the index.
Why can a small move in a big stock matter more than a big move in a small one?
Because contribution scales with weight. A stock that is 10% of an index and rises 1% adds 0.10 percentage points; a stock that is 0.5% of it and rises 10% adds only 0.05.
Is the contribution table live?
Yes, in market hours its sector rows refresh every 10 seconds. A sector or sub-sector you open shows its stocks as of when you opened it; open it again for the latest. Outside market hours it shows the last session.
Can I see the contribution table on a phone?
The table is on a computer. On a phone, the same address shows the heatmap of the same stocks.
Do I need an account?
No. The table is free to use at its own address. Switching from it to the heatmap view asks you to sign in, and signing up is free.
Is the heatmap investment advice?
No. The heatmap and the contribution table show market data for information only. They are not a recommendation to buy or sell anything.
The Nifty 500 contribution table shows what actually moved the index today, sector by sector and stock by stock. Market data for information only, not a recommendation.
