How it works
The new share count is the shares you hold times the new count, divided by the old count. The new price is the old price times the old count, divided by the new count.
A split changes the number and the price together, so the value of your holding is the same on the day of the split. Market moves after the split are not included.
Worked example
With 100 shares at $400.00 before the split, a split of 1 for 4 gives 400 shares at $100.00 each, a holding worth $40,000.00.
Questions
What does a 4-for-1 split mean?
You receive four shares for each one you held, and the price per share falls to about a quarter of its old level.
Is a split the same as a dividend?
No. A split only changes the number of shares and their price. It does not pay cash.
Does a reverse split work the same way?
Yes, with the numbers flipped. Enter a larger old count and a smaller new count, and the share count falls.
