How to Find ASX Stocks Market Capitalisation?

Market capitalisation (also called market cap) is the total dollar value of a company's outstanding shares. It is also the overall value of a company according to the market. The formula for market capitalisation is the company's shares multiplied by the current market price of one share. For example, company ABC has 45 million shares outstanding, each with a market value of $100. The company's market capitalisation is $4.5 billion (45 million x $100 per share).
