Stock Market
Read this paper Q.1 For each stock in the stock market, the number of shares sold daily equals the number of shares purchased. That is, the quantity of each firms shares demanded equals the quantity supplied. So, if this equality always occurs, why do the prices of stock shares ever changes?
Ans. During any stock trading session, there are buyers and sellers, each willing to buy or sell a certain number of shares depending on the price of that share. If at the current price (e.g. the days opening price) the quantity of shares demanded exceeds the quantity of shares supplied, buyers must increase their price offers to induce sellers to offer enough shares. This will cause share prices to rise until quantity demanded equals quantity supplied. Suppose that during the trading session there is a report of bad economic news. Sellers may respond by trying to sell more shares than buyers are wanting at the current price. In order to find enough willing buyers, sellers will have to offer their shares at lower prices. On any given trading day, there will be multiple equilibrium prices, many of them not lasting for more than a few minutes (or even
seconds).
