The supply and demand determine a share price. If the demand is high, it will increase, and if the demand is low, it decreases. Stock prices depend on the bid and ask of the stock. A bid is an offer to buy a certain number of shares for a specific price. An ask is an offer to sell a certain number of shares at a particular price.
Exchanges calculate a stock's price instantly by finding the price at which the maximum number of shares are transacted at the moment. The price changes if there is a change in the buy or sell offer of the shares.
How to calculate the market price of a share?
To determine the market cap of a share, you need to estimate the market price of the share. To figure out how valuable the shares are for traders, take the last updated value of the company share and multiply it by outstanding shares.
Another method to calculate the price of the share is the price to earnings ratio. You can calculate the P/E ratio by dividing the stock price by its earnings in the last 12 months.
The intrinsic value of stock = P/E ratio X Earning per share
Growing companies generally have a higher P/E ratio while established business have slower P/E growth rates.
