How exactly is Nifty movement calculated ? I know that few stocks are given weightage and it depends on their price move . My question is how is that price move in all the 50 stocks converted to nifty 15000 approx points ?
Can check this, go through factsheet, constituents also which stock is contributing how much for index movement.
This blog post briefly explains how to calculate the value of the index -
In case you don’t want to calculate it on your own, you can check the Index constituents page on the Tickertape website for Nifty50. It gives an overview of how each stock affected the Nifty50 index based on its weightage on a daily basis -
What happens to the dividends issued by the 50 stocks? Will that affect nifty price? How will nifty based etf handle these dividends?
The Methodology document for Nifty Indices (Page 133) explains how dividends are handled when calculating the index value -
Maintenance of NIFTY indices includes carrying out adjustments for corporate actions like stock splits, stock dividends, share changes and scheme of arrangements. Some corporate actions, such as bonus, stock dividends*, stock splits and reverse stock splits require simple changes in the equity shares outstanding and the stock prices of the companies in the index.
Other corporate actions such as change in equity, rights issue of shares, special dividend, change in investible weight factor (IWF) / free float results into change in the market value of an index overall and require a divisor adjustment to prevent the value of the index from changing
* - The word stock dividends isn’t mentioned in the current document but was mentioned in the previous index methodology documents (page 7)
Varsity mentions that ETFs follow the TRI version of the index -
Note: Always compare the ETF price with the total returns index (TRI) and not the price returns the index (PRI). The TRI includes dividends. All the index data you see on Kite is PRI. Since ETFs track TRI indices, they re-invest the dividends which reflects in the NAV of the ETF.
In case you are interested, the Methodology document for Nifty Indices (Page 136) talks about how TRI calculation is done -
