The stock price refers to the price when the stock is bought and sold in the securities market. The stock itself has no value, just a certificate. It has a price because it can bring dividend income to the holder, so buying and selling stocks is actually buying and selling a voucher to get dividend income. The face value is the basis of participating in the company's profit distribution, the dividend level is the ratio of a certain amount of share capital to realized dividends, and the interest rate is the interest rate level of monetary capital. The buying and selling price of stocks, that is, the level of the stock market, directly depends on the amount of dividends and the interest rate of bank deposits. It is directly influenced by supply and demand, and supply and demand are influenced by many factors inside and outside the stock market, which makes the stock market deviate from its par value. For example, the company's operating conditions, reputation, development prospects, dividend distribution policies, external economic cycle changes, interest rates, money supply, and national politics, economy, and major policies are all potential factors that affect stock price fluctuations, while the trading volume, trading methods, and the composition of traders in the stock market can all cause short-term stock price fluctuations. In addition, artificially manipulating stock prices will also cause stock price fluctuations. The stock price refers to the transaction price of the stock, which is a concept relative to the stock value. The real meaning of stock price is the value of enterprise assets. The value of the stock price is equal to the earnings per share multiplied by the price-earnings ratio.
