Index Tutorial - Price Weighted Index

指数期权教程 - 价格加权指数

Each component stock of a price-weighted index has the same number of shares in the index. Price-weighted is to add the price of each stock in the index together and divide by a divisor to get the value of the index.


The divisor can be any specified number used to generate the initial index value such as 50 or 100. For example, when the index is issued, the stock value adds up to 200. In order to make the initial value of the index 100, the divisor is 2.

价格加权指数的每一只成分股在指数中的股份数都是相等的,价格加权是将指数中每一只股票的价格加在一起,除以一个除数得到指数的价值。


除数可以为任意指定数字,用来产生最初指数价值例如50或者100。比如指数在发行时股票价值相加为200,为了让指数初始价值为100,除数为2。
