A stock split changes how many shares exist and the price of each — but not what your stake is worth. It's like cutting a pizza into more slices: more pieces, same pizza.
A stock split increases the number of a company's shares while proportionally lowering the price of each one. If you own 10 shares worth $200 each ($2,000 total) and the company does a 2-for-1 split, you suddenly own 20 shares worth $100 each — still $2,000. Nothing about the value of your stake or the company changes; only the units do.
The most common reason is accessibility. When a single share costs hundreds or thousands of dollars, smaller investors can feel priced out. Lowering the per-share price can widen the shareholder base and improve trading liquidity. Splits are also a confidence signal: a company usually only splits after its price has climbed a long way.
A split ratio can be 2-for-1, 3-for-1, 10-for-1 or anything else. In every case you multiply your share count by the ratio and divide the price by the same ratio. Your market cap exposure is unchanged.
A reverse split does the opposite: it reduces the share count and raises the price. A 1-for-10 reverse split turns 100 shares at $0.50 into 10 shares at $5.00. Companies often do this to lift a low price back above an exchange's minimum listing requirement — which can be a warning sign that the stock has been struggling.
The key insight: a split is pure arithmetic. It does not create or destroy value — it just re-slices it. Watch out for headlines that treat a split itself as good or bad news.

No. A split changes the number of shares and the price proportionally, so your total value is unchanged the instant it happens. Any gain afterward comes from the price moving, not the split itself.
It doubles your share count and halves the price of each share. Ten shares at $200 become 20 shares at $100 — the same $2,000 total.
A reverse split reduces the share count and raises the price per share, for example turning 100 shares at $0.50 into 10 shares at $5.00. It is often used to meet a minimum listing price.
Mainly to make a single share more affordable and to improve liquidity after the price has risen a long way. It can also signal management confidence.
