Reverse split meaning
A reverse stock split is when a company combines its existing shares into fewer new shares. The price of each share goes up in proportion, so the total value of each holding stays the same at the moment of the split. It is also called a share consolidation.
Formal definition
A reverse split is a corporate action. The issuer replaces a fixed number of old shares with one new share at a ratio set by its board and, where required, its shareholders. The number of shares outstanding falls. The face value (par value) per share usually rises by the same factor. Market capitalisation, the shareholders' combined ownership percentage, and the company's assets and book value do not change because of the split itself.

Worked example (hypothetical)
Take a hypothetical holder with a block of shares in a company that announces a consolidation at a fixed ratio.
| Item | Before | After |
|---|---|---|
| Shares held | Original count | Original count divided by the ratio |
| Price per share | Original price | Original price multiplied by the ratio |
| Value of holding | Unchanged | Unchanged |
| Ownership share of the company | Unchanged | Unchanged |
After the split, the holder owns fewer shares, and each one is priced higher. The holding is worth the same at the moment the split takes effect. Any gain or loss after that comes from normal price movement, not from the split.
Stock split vs reverse split
| Stock split | Reverse split | |
|---|---|---|
| Share count | Increases | Decreases |
| Price per share | Falls | Rises |
| Total value at the split | Unchanged | Unchanged |
| Common reason | Make a high share price easier to trade | Lift a low share price, often to meet exchange listing rules |
Markets often read a reverse split as a sign of a weak share price, because companies frequently use it to avoid delisting under a minimum-price rule. It says nothing certain about the stock's future direction.
Where you see the term
- Charts on trading platforms: historical prices are usually adjusted so the chart has no artificial jump. Unadjusted data shows a sudden gap on the effective date.
- Broker notices and account statements: a line shows old shares removed and new shares credited. An account statement may also show a small cash entry for fractional shares.
- CFDs on shares: providers adjust position size and price to reflect the action. Check the provider's corporate-action notice for the exact treatment.
- News and filings: look for phrases such as "share consolidation", "reverse split ratio" and "effective date".
Edge cases experienced traders check
- Fractional shares: if a holding does not divide evenly by the ratio, the leftover fraction is usually paid out in cash. That cash can create a taxable capital gain or loss.
- Pending orders: stop and limit orders may be cancelled or repriced on the effective date.
- Options: contracts are adjusted, so the deliverable per contract may change and differ from the standard contract size.
- Depositary receipts: an ADR or GDR ratio can change instead of, or as well as, the underlying share count.
- Liquidity: a smaller free float can mean wider spreads and sharper moves. Leveraged positions in such stocks, including CFDs, can lose money fast.
- Index data: index providers adjust divisors so the index level does not jump. See stock indices.

A company combines several of its shares into one. You own fewer shares, each at a higher price, and the total value is the same at that moment.
Does a reverse stock split make me lose money?

Why do companies do a reverse split?
Usually to raise a low share price. Common reasons are meeting exchange listing rules or improving how the stock is perceived.
What happens to fractional shares?
They are usually paid out in cash. The terms are set in the company's announcement and by your broker.
Are price charts affected?
