About & method

This site shows where market capitalisation was added or lost across Indian listed companies, grouped by sector and by company size, using end-of-day data published by the National Stock Exchange of India (NSE). It updates once per trading day after the market closes.

Which stocks

The universe is the constituent list of the Nifty Total Market index (about 750 companies, covering most of the market's value), published on niftyindices.com. F&O only narrows this to stocks with derivatives on NSE, using NSE's official F&O lot-size list.

Sectors and size

Sector is NSE's own classification of each company, as shown in the index constituent list. Size is Large cap (Nifty 100), Mid cap (Nifty Midcap 150), Small cap (Nifty Smallcap 250) or Micro cap (the remaining Total Market stocks).

How the numbers are made

• Market cap: NSE's official daily market-cap file, so splits and bonuses are already handled by the exchange.
• MCap added: market cap today minus market cap at the start of the period, counting only stocks listed at both ends.
• Index lines: market-cap weighted, chain-linked daily and rebased to 100 at the period start.
• Universe: today's index list is applied to the whole history, so stocks that joined or left the index during the period are treated as if they had always been in it.

Rotation

The rotation chart is an open approximation of a relative rotation graph built from daily data. RS is the group index divided by the benchmark, lightly smoothed. RS-Ratio = 100 × RS ÷ its 21-day average. RS-Momentum = 100 × RS-Ratio ÷ RS-Ratio five days earlier. The quadrants describe past relative performance only.
