Stock income, that is, stock investment income, refers to the difference between dividends obtained by enterprises or individuals from foreign investment in the form of buying stocks, the amount obtained from transferring and selling stocks and the actual cost of stocks, and the amount of equity investment in the net assets increased by the invested unit. Stock income includes dividend income, capital gains and transfer income from provident fund.

Common stock refers to the shares that enjoy common rights in the company's operation and management, profit and property distribution, and represents the right to claim the profits and remaining property of the enterprise after meeting the requirements of full repayment of creditor's rights and the income and creditor's rights of priority shareholders. Common stock constitutes the foundation of a company's capital and is a basic form of stock. At present, the stocks traded in Shanghai and Shenzhen stock exchanges are all common stocks.

After the rights issue, it refers to the shares that are at a disadvantage compared with ordinary shares when distributing interest or interest dividends and remaining property. Generally, after the distribution of common shares, the residual interests are redistributed. If the company's profits are huge and the number of shares issued after the rights issue is limited, the shareholders who buy the rights issue can get high returns. After the rights issue, the raised funds generally can't generate immediate income, the range of investors is limited and the utilization rate is not high.

The stock itself has no value, but it can be sold as a commodity at a certain price. The stock price is also called the stock market, which is not equal to the face value of the stock. The par value of a stock represents the monetary capital invested in the stock, which is fixed; However, the stock price is changeable, and it is often larger or smaller than the face value of the stock. The buying and selling of stocks is actually the right to get dividends, so the stock price is not the monetary expression of the actual capital value it represents, but a capitalized income. Stock prices are generally determined by dividends and interest rates. For example, if there is a stock with a face value of 100 yuan, it can get a dividend of 10 yuan every year, that is, a dividend of 10%, and the interest rate at that time was only 5%, then the price of this stock is 10 yuan ÷5%=200 yuan. The calculation formula is: share price = dividend/interest rate.

It can be seen that the change of stock price is directly proportional to dividend and inversely proportional to interest rate. If a joint-stock company is in good operating condition, dividends increase or expected dividends increase, the share price of this joint-stock company will rise; On the contrary, it will fall.
