Index Tutorial - Market Cap Weighted Index

指数期权教程 - 市值加权指数

The market value of a stock is the total value of securities in its market, which is the product of the number of issued shares and the current price.

In a market value-weighted index, the sum of the market value of all stocks is the total market value of the index, that is, the price of each stock in the index is multiplied by the total equity issued by the stock to get the sum, and this sum is divided by the divisor to get the final index value.


The divisor can be any designated number. For example, when the index is issued, the total market value of the stock price reaches 15B, and the initial value of the index is set to 100, then the divisor will be 150M.

一只股票的市值是它市场上流通证券的总价值,是发行股份数量和当前价格的乘积。

在一个市值加权的指数中,所有股票的市值的总和为该指数的总市值,即为指数中的每一只股票的价格乘以股票发行的总股本得到总和,这个总和被除数所除得到最终指数价值。


除数可以为任意指定数字,比如在指数发行时股价总市值达到15B,设定指数最初价值为100,那么除数就会是150M。
