What Is a Stock Split?

A stock split increases the number of shares a company has while reducing the price of each share by the same proportion. In a 2-for-1 split, every share you own becomes two, each worth half as much. Ten shares at 200 dollars become twenty shares at 100 dollars.

The key insight is that your total value does not change. You owned 2,000 dollars before the split, and you own 2,000 dollars after. The pie is the same size; it is just cut into more slices.

A forward split, like 2-for-1 or 10-for-1, raises the share count and lowers the price per share. Companies usually do this after the price has risen a lot, to make a single share feel more accessible.

A reverse split does the opposite, combining shares to raise the price per share, for example 1-for-10. This is often done to lift a very low price back up, sometimes to meet an exchange's minimum listing requirements. A reverse split can be a sign of trouble, so it is worth understanding why a company is doing it.

If a split does not change value, why bother? The main reason is psychology and accessibility. A stock priced at 3,000 dollars per share can feel out of reach to small investors, even though the price per share says nothing about whether it is expensive in a meaningful sense.

Lowering the nominal price can widen the pool of potential buyers and make the stock easier to trade in small amounts. With fractional shares now common, this matters less than it once did, but splits still happen and still grab attention.

If you own a stock that splits, you do not need to do anything. Your broker adjusts your share count and the price automatically, and your total position is unchanged. There is no tax event and no action required.

The useful habit is to not be fooled by the lower price afterward. A stock is not on sale just because a split made each share cost less. To judge size and value, look at market capitalization rather than the price of a single share.
