The sizes of companies on the stock market are often measured by their market capitalization (aka, market cap), which is calculated by multiplying the stock price by the number of shares issued. When you hear investors refer to the largest companies on the stock market, they’re usually not talking about size in terms of number of employees or even necessarily gross profits; they often mean the largest companies by market cap. 

Market capitalization is considered a measure of business maturity. High-market-cap companies are typically seen as better established, with a greater market presence. Many investors believe that high-market-cap companies have a solid chance of providing reliable returns because they see them as more stable in the face of stock market volatility, with less extreme swings in the market value of their stocks.

In 2024, the 15 largest companies by market cap span multiple sectors, including energy, healthcare, financial services, and technology. And while no one sector dominates the list, over half of these companies are in or related to the tech sector; measured by market cap, the technology industry can be seen as one of the largest in the market.
