What is the purpose of the Dow Divisor?

Reference answers:
The Dow has increased by approximately 0.20%, which amounts to 83.60 (41,883.6 - 41,800). The stated divisor value of 0.15173 indicates that each $1.00 change in an underlying stock price corresponds to a 6.5906 change in the Dow (1.00 / 0.15173).

The 83.60 change in the Dow correlates to a cumulative change of 12.684 in the underlying stock prices of the index.

In other words, the $5.00 increase in Apple stock accounts for 39.4% of the Dow's daily gains (5 / 12.684).

The Dow Divisor is crucial for calculating the Dow Jones Industrial Average, which tracks the stock prices of 30 major companies and serves as a measure of the overall performance of the U.S. stock market.

The Dow Divisor helps ensure that changes in the index's components—such as stock splits or the addition or removal of companies—do not distort the value of the DJIA. It keeps the index focused on actual price changes, minimizing the impact of other factors.
