As you might have guessed, calculating the DJIA today isn’t as simple as adding up the stocks and dividing by 30. Dow lived at a time when stock splits and stock dividends weren’t commonplace, so he didn’t foresee how these corporate actions would affect the average. For example, Apple is one of the largest companies in the world and, as of November 2024, has the largest weight in the market-cap-weighted S&P 500 based on its market cap of $3.35 trillion. But in the Dow, it has just the 13th largest weight, which is based on its share price of about $221. UnitedHealth Group has the largest weight in the Dow because of its $559 share price despite having a market cap that is less than 20 percent of Apple’s.
