How Does the Dow Jones Work?
Unlike many other indexes, the Dow Jones is a price-weighted index. This means companies with higher stock prices have a bigger impact on the movement of the index.
For example:
A company trading at $400 per share affects the Dow more than a company trading at $50 per share.
Even if the lower-priced company is larger in total market value.
This method is different from indexes like the S&P 500, which use market capitalization weighting.
