Stocks come in various sizes, but the largest ones are known as mega caps. These are stocks with the highest market capitalizations, often exceeding $200 billion. Although the exact threshold can vary, mega cap stocks are generally the biggest and most globally influential companies.
A mega cap stock is typically defined as a company with a market capitalization greater than $200 billion. While the term “mega cap” is used to describe these colossal companies, it’s distinct from small-cap, mid-cap, and large-cap stocks, which refer to companies of different sizes.
Mega cap stocks are usually well-established firms with substantial revenues, often reaching into the tens of billions of dollars. Prominent examples include household names like Apple, Amazon, and Tesla, as well as less familiar giants like Berkshire Hathaway and Broadcom. These companies often have a global footprint, with operations spanning multiple regions.
In broad market index funds, such as those tracking the S&P 500, mega cap stocks make up a significant portion of the portfolio. For instance, as of July 2024, Apple and Microsoft together accounted for over 13% of Vanguard’s S&P 500 ETF. Investors might already have substantial exposure to these mega cap companies through their investments without even realizing it.
