What is the Margin Trading System (MTS) on the PSX?
MTS is a regulated PSX facility that lets investors borrow funds to buy shares, using the shares as collateral and amplifying both gains and losses.
The Margin Trading System (MTS) is a regulated facility on the Pakistan Stock Exchange that lets an investor borrow money to buy shares, putting up only part of the purchase price themselves and financing the rest. The shares bought act as collateral for the loan. MTS is leverage in a controlled, exchange-supervised form.
Here is the idea. Suppose you want Rs 100,000 of a stock but only commit Rs 30,000 of your own money; under a margin facility you borrow the remaining Rs 70,000. If the stock rises, your return is calculated on the full Rs 100,000 position while you only invested Rs 30,000, so your percentage gain is magnified. The borrowed amount carries a financing cost (a markup), and the lender — funded through the system — earns that return.
The crucial point is that leverage cuts both ways. Just as gains are amplified, so are losses. If the stock falls, the loss is also measured against the full position, so a relatively small price drop can wipe out a large share of your own capital. To manage this, MTS positions are subject to margin requirements and mark-to-market rules: if the value of your collateral falls below a threshold, you receive a margin call to deposit more funds or your position may be liquidated (sold) to repay the loan — potentially at a bad time and a bad price.
MTS sits alongside other PSX leverage and financing products and is overseen by the exchange and the National Clearing Company (NCCPL), which administers the system, sets eligible securities, and manages risk parameters. Only certain liquid shares are typically eligible, and there are limits on how much can be financed.
The appeal of MTS is capital efficiency — controlling a larger position with less cash, and the chance of higher returns. The danger is that the same leverage can turn an ordinary market dip into a serious loss, and forced liquidation can crystallise losses at the worst moment. Financing costs also eat into returns, so the stock must rise by more than the markup just to break even.
For these reasons, margin trading is best treated as an advanced tool for experienced, risk-aware investors who understand margin calls and position sizing. New investors are usually better served building positions with their own capital before considering leverage.
