Extended data

The market price of stocks is determined by the market. The face value and market value of stocks are often inconsistent. The stock price can be higher or lower than the face value, but the price of the initial stock issue is generally not lower than the face value. The stock price depends on the expected dividend, bank interest rate and the relationship between supply and demand in the stock market. The stock market is a volatile market, so is the stock price.

The market transaction prices of stocks mainly include: opening price, closing price, highest price and lowest price. The closing price is the most important, which is the basic data used to study and analyze the stock market and suppress the stock market trend chart.
