How it works
A 4-for-1 split turns each share into four, each worth a quarter of the old price. The position is worth the same.
Shares after = Shares × New / Old
Price after = Price × Old / New
A reverse split, such as 1-for-10, works the same way in the other direction. Past splits compound: one share before two 2-for-1 splits is four shares today.
