  1. The number that divides the index

A divisor is used to keep the number the same over time, even when things happen like mergers, share splits, or new shares are issued. This makes sure that changes like these don’t mess up the index.

The measure is updated every day from 8 a.m. to 4:30 p.m. Eastern Time, so it always shows how the market is doing.
