The initial calculation of the Dow Jones index is relatively simple, using the average number of points obtained by simple arithmetic. When the stock is ex-dividend, once this happens, there will be a big gap in the stock, and the trend of the stock will be incoherent.
Therefore, after 19828, the Dow data analysis platform adopted a new calculation method to ensure the consistency of the stock index and spread it around the world. The calculation is as follows:
Initial calculation formula: average stock price = sum of selected stock prices/number of selected stocks.
The improved formula: average share price = sum of the prices of the selected stocks/divisor of the Dow will be affected by the integration of share split and the company.
