01What is Capital Gain?

The definition — and what it means in practice.

A capital gain is the profit you make when you sell a security for more than you paid for it. It is usually measured as the sale proceeds minus the purchase cost, and it can be calculated per share or for your whole holding. If you sell for less than your cost, that is a capital loss. In Pakistan, capital gains tax can apply to gains on listed securities, with rates linked to holding period.

Capital gains matter because they are a core part of your overall return, alongside dividends and other cash flows. They also affect how you plan exits, rebalancing, and risk controls, since a gain is only “realised” when you sell. In practice, your net gain depends on transaction costs such as brokerage commission and on tax treatment, so the amount you keep can differ from the headline price move.

In plain English

If you buy a share at Rs 100 and sell at Rs 130, your capital gain is Rs 30 (before brokerage, taxes, and other charges).

Formula

Capital Gain = Selling Price − Purchase Price

Use per-share prices, or multiply by number of shares; consider charges and taxes separately.

  • A capital gain is profit realised when you sell above your purchase price.
  • Gains are not locked in until you sell; before that, they are unrealised.
  • Net gains can be reduced by brokerage commission and other charges.
  • In Pakistan, capital gains tax on listed shares depends on holding period and filer status.

02How capital gain works on the PSX

The Pakistan-specific rules, conventions, and numbers.

On the Pakistan Stock Exchange (PSX), capital gains are typically realised when your sale trade settles and the shares move electronically through the Central Depository Company (CDC) system. Trades clear through the National Clearing Company of Pakistan Limited (NCCPL), and settlement is T+1 (one business day). In day-to-day investing, the “gain” you see is tied to your buy and sell execution prices, not just a company’s fundamentals.

For Pakistani investors, capital gains are also a tax concept. Capital gains tax can apply to gains on the sale of listed shares, and the applicable treatment can depend on how long you held the position and whether you are a filer; the details can change with Finance Acts. Practically, this means your after-tax outcome may differ even when two investors have the same pre-tax profit on a PSX trade.

03Common misconceptions

Where investors most often get this wrong.

Myth

My capital gain is the same as the stock’s percentage increase.

Reality

Your gain depends on your own purchase and sale prices (and quantity), plus charges. The stock’s move is only a reference.

Myth

I have a capital gain as soon as the price goes up.

Reality

That is an unrealised gain. It becomes a realised capital gain only when you sell the security.

Myth

Capital gains tax is always the same rate in Pakistan.

Reality

For listed shares, the tax treatment can vary by holding period and filer status, and can change with Finance Acts.
