Reweighting The Dow Jones Industrial Average

There are thirty stocks in the Dow Jones Industrial Average (DJI), the U.S. stock market's oldest running index. Unlike the S&P 500 (SPX), the market capitalization-weighted index that's overtaken it as standard for measuring the performance of the U.S. stock market, the component stocks of the DJI are weighted according to their price.

For example, the stock of Goldman Sachs (NYSE: GS) has the heaviest weight within the index, accounting for 11.72% of its value on 27 July 2026 thanks to its highest-in-the-index share price of $1,041.82.

With a share price of $837.24, Caterpillar (NYSE: CAT) ranks second, making up 9.42% of the index. The third largest component stock of the DJI belongs to United Health (NYSE: UNH), whose share price of $427.54 gives it a 4.8% share of the entire Dow Jones Industrial Average.

The following chart visualizes the relative share of each of the DJI's 30 component stocks within the index:

We wondered how this chart would change if the thirty Dow Jones Industrial component stocks were weighted within the index according to their market capitalization. The next chart shows the results of that exercise, keeping the order and coloring of the component stock shares the same as the price-weighted visualization:

The DJI's top three components of Goldman Sachs, Caterpillar, and United Health go from accounting for a combined 25.94% of the index to just 4.23%. In their place, the top three component stocks of become Apple (Nasdaq: AAPL), Nvidia (Nasdaq: NVDA), and Microsoft (Nasdaq: MSFT), which would account for 49.7% of the entire DJI's valuation.
