Stock split
Stock split doubles shares, halves price
A stock split increases the number of shares in a company. For instance, a 2-for-1 split means each investor will own double the number of shares. However, the price of each share will be reduced proportionally, making it more affordable for investors.
A stock split does not change the total market capitalization of the company. Market capitalization remains the same because the increase in the number of shares is offset by the decrease in the price of each share. This ensures that the overall value of the company remains unchanged.
Stock splits are often initiated when the market price per share becomes too high, making it difficult for small investors to buy shares. By reducing the share price, stock splits make the shares more accessible to a broader range of investors.
Example
If a company has 1 million shares priced at $100 each, after a 2-for-1 split, it will have 2 million shares priced at $50 each. The total market capitalization remains $100 million.
Understanding stock splits helps investors recognize that the fundamental value of a company remains unchanged, despite changes in share price and share count.
