Market capitalisation and company size
Market capitalisation, commonly referred to as "market cap", describes the relative size and value of a listed company within the broader market. In the South African (SA) context, market capitalisation plays a significant role in evaluating companies listed on the Johannesburg Stock Exchange (JSE), ranging from large multinational corporations to smaller emerging businesses. Beyond size, it also offers insight into risk, return expectations, liquidity and growth potential as well as understanding how companies may perform during different economic and market cycles.
