Market cap, short for market capitalisation, is the total value of a company’s outstanding shares, calculated by multiplying the share price by the number of shares issued. It’s a quick way to assess a company’s size, and can give insights into its stability and how it compares with others in the market.
The rankings can shift due to company earnings, mergers, sector performance, or broader economic trends. While some large caps stay at the top for years, sudden price changes or market shifts can see others move in or out of the top spots.
