In stocks, the so-called weighting refers to the average value after adding the weight ratio. It refers to a weighted index. A certain fund investment industry uses a specific weighted balance method to buy stocks of different companies. This can diversify investments, reduce risks, and can also be used to represent the performance of a certain industry or the stock market;

For example, the A indicator consists of two stocks. The stock price of one stock is 5 yuan, and the stock price of the other stock is 5 yuan. It's 10 yuan.

The average value is (5+10)/2=7.5 yuan. This is unweighted.

Weighting is used in two places in the stock market:

1. The average line is a few lines in the trend chart, which is an average calculated based on historical values; this will not change Value;

2. Weighting such as bonus shares, allotment of shares, dividends, etc. Because the total stock market has become larger or smaller, in order to ensure value, weighting is needed. At this time, although the stock price has become 7.5, but If you check the account number, you will see that the number of shares has increased. It used to be 100 shares, but now it is 106 shares. If you give away 10 shares, it will be 116 shares. Don't worry about losses. The price displayed on the trend chart after 3 o'clock is the closing price of the day and is not weighted. But futures are different. The price displayed by futures is the weighted price of the day.
