FAQ
Does a split make me richer?+
No. The total value of your holding stays the same. Splits are mostly cosmetic, although they can make a stock feel more affordable to small investors.
What happens to fractional shares?+
Most brokers issue fractional shares post-split. The tool floors to whole shares for simplicity, but in reality you'll keep the exact value.
