What is a share buyback
A share buyback, also called a stock buyback or share repurchase, is when a company uses its own money to buy back shares it issued earlier from its shareholders.
After a buyback, fewer shares remain in the hands of investors. Each remaining share represents a larger slice of the same company.

Worked example (hypothetical)
Take an imaginary company, Company A, listed on an exchange:
| Item | Before buyback | After buyback |
|---|---|---|
| Shares held by investors | A set number | Fewer, because some were bought back |
| Yearly profit | Unchanged | Unchanged |
| Profit per share (EPS) | Profit ÷ more shares | Profit ÷ fewer shares, so higher |
| Cash on the balance sheet | Higher | Lower by the amount paid |
| Your ownership share, if you did not sell | Smaller | Larger |
Earnings per share (EPS) rises even though total profit did not grow. Analysts separate this effect from real growth in profit.
The company's cash also falls by the amount it spent. That lowers its equity and changes its book value.
Formal definition and mechanics
In formal terms, a buyback is a corporate action in which an issuer acquires its own issued shares and reduces the number of shares outstanding. Common methods include:
- Open-market purchase: the company buys shares on the exchange over a period, at market prices.
- Tender offer: the company offers to buy a stated quantity at a fixed price, often above the market price, and shareholders choose whether to sell.
- Negotiated purchase: the company buys a block of shares from a specific holder.
Bought-back shares are either cancelled or held as treasury shares. Treasury shares carry no vote and receive no dividend. Which option is allowed depends on company law in each country.
Edge cases experienced readers watch
- Partial acceptance: if more shareholders offer shares in a tender than the company wants to buy, each seller may have only part of their offer accepted.
- Debt-funded buybacks: a company that borrows to buy back shares raises its leverage and its interest costs.
- Offsetting dilution: some buybacks only cancel out new shares issued to employees, so the share count barely falls.
- Free float: a large buyback shrinks the free float. This can reduce liquidity and sometimes comes before a delisting.
- Buyback vs dividend: both return cash to shareholders. A dividend pays every holder, while a buyback pays only those who sell. See ex-dividend and record date and capital gain and loss.
Where you see the term
- Buyback of shares on PSX: listed Pakistani companies announce corporate actions, including buybacks, through Pakistan Stock Exchange notices. Read the company's own notice for the price, quantity and period.
- Annual and quarterly reports: look for "purchase of own shares" or "treasury shares" in the equity statement and the cash flow statement.
- News and platforms: buyback announcements appear in financial news and in the news feeds of trading platforms. They often move a share's price and sometimes an index. See stock indices.
A buyback is a piece of company information, not a signal. A price can fall after an announcement as easily as it can rise. If you trade share or index CFDs with leverage, you can lose money fast. Read risk management before trading around company news.
