The closing price represents the final price that a stock is traded for on a trading day.  It’s the most up-to-date valuation until trading begins again on the next day. However, most financial instruments are traded after hours, which means that the the closing price of a stock might not match the after-hours price.  Regardless, closing prices are a useful tool that investors use to quantify changes in stock prices over time.  The closing prices are compared day-by-day to look for trends and can measure market sentiment for any security over the course of a trading day.

Stock exchanges work according to the invisible hand of supply and demand, which determines the price where stocks are bought and sold.  No trade can occur until someone is willing to sell a stock at a price that another is willing to buy it at.  When there are more buyers than sellers, the stock price will rise because of the increased demand.  Conversely, if more individuals are selling a stock, the price will decrease.

On any given trading day, supply and demand fluctuates back-and-forth because the attractiveness of a commodity’s price rises and falls.  Because of these fluctuations, the closing and opening prices are not necessarily identical.  A number of factors can affect the attractiveness of a stock in the hours between the closing bell and the next day’s opening bell.  For example, if there is good news like a positive earnings announcement, the demand for a stock may increase, raising the price from the previous day’s close.  It follows that bad news will negatively affect price.
