Stock Index Introduction

The stock index is the stock price index. It is a kind of reference number prepared by a stock exchange or financial service institution to indicate changes in the stock market. As stock prices fluctuate, investors are bound to face market price risks. Investors are easy to understand the price changes of a particular stock, and it is not easy or annoying to understand the price changes of multiple stocks one by one. In order to adapt to this situation and needs, some financial service institutions use their own business knowledge and advantages of being familiar with the market to compile stock price indexes and then release them publicly as an indicator of market price changes. Investors can then check the effectiveness of their investment and use it to predict the stock market movements.

Calculation method of stock index

When calculating the stock index, the stock index and the stock price average are usually calculated separately. By definition, a stock index is the average stock price. But in terms of the actual effect of the two on the stock market, the average stock price can reflect the general level of changes in the price of various stocks, which is usually expressed as an arithmetic average. By comparing the average number of stock prices in different periods, one can recognize the level of change in various stock prices. The stock index is a relative indicator that reflects the stock price changes in different periods, that is, a percentage of the average stock price in the first period as the benchmark for the average stock price in another period. Through the stock index one can understand the percentage ratio of the stock price in the calculation period to the stock price in the base period. Because the stock index is a relative indicator, for a long period of time the stock index can measure the movement of the stock price more accurately than the average value of the stock price.
