Depending on the number of shares, there are fully diluted earnings per share and weighted average earnings per share. Fully diluted earnings per share refers to the total number of ordinary shares at the end of the calculation, because newly issued shares are generally issued at a premium, and new and old shareholders share the income before the company issues new shares. Weighted average earnings per share refers to the data that the total number of shares is weighted monthly to calculate the number of shares, because the capital and assets invested by the company are different, and the basis for generating income is also different.
Can be weighted according to the total share capital. The price-earnings ratio of each of the five companies * the total share capital of each company is added and divided by the total share capital of the five companies.
