The big picture
MTS changes the funding of a securities position; it does not improve the underlying business or remove price risk. Borrowing can make a modest share-price move a large change in your own capital. This topic separates the regulated facility, the arithmetic and the practical obligations. It also explains why a stop instruction cannot replace cash capacity or a financing agreement.
Core concepts
Learning objectives
- Distinguish MTS from cash investment and other leveraged products.
- Calculate how price changes affect investor equity.
- Build a conditional margin-threshold worksheet without inventing an official rate.
- Evaluate financing, liquidity and exit obligations together.
Identify the facility and the parties
1.1 MTS is a specific financing arrangement
MTS supports financed positions in eligible securities under the applicable NCCPL framework and intermediary arrangements. The investor contributes capital while financing supports the remainder. It is not interchangeable with a futures contract, an ordinary unpaid purchase or the historical Badla arrangements sometimes used as a loose description. Product names matter because funding, collateral, maturity and default obligations differ.
1.2 Eligibility, consent and documentation
Read the signed terms, eligible-security list, account permissions and current notices before calculating a position. A broker may impose conditions stricter than a regulatory minimum. Do not infer personal access from an educational product page. Identify who provides finance, how securities are held, what can trigger additional collateral and which close-out rights apply. A blank or poorly understood agreement is not cured by a small initial position.
Step-by-step method
- Identify the exact product and eligible account route.
- Obtain current financing and collateral terms in writing.
- Record the financier, broker responsibilities and consent requirements.
A learner sees a leveraged feature on a platform. Before using it, the learner establishes whether it is MTS, another facility or merely a displayed buying-power estimate; each requires its own documentation.
Calculate the effect on your own capital
2.1 Exposure is larger than equity
In a simple financed long position, asset value equals quantity multiplied by market price. Investor equity is asset value minus outstanding financing and accrued obligations. Leverage compares exposure with that equity. The loan does not shrink automatically when the share price falls, so the investor absorbs the first change in value. Cash investment and financed investment can own the same shares while producing different percentage outcomes on contributed capital.
2.2 Price losses amplify equity losses
Teaching assumptions: buy 1,000 shares at PKR 100 with PKR 40,000 own capital and PKR 60,000 financing. At PKR 90 the assets are PKR 90,000 and equity is PKR 30,000 before costs, a 25% equity loss from a 10% share-price decline. At PKR 80, equity is PKR 20,000, a 50% loss. These invented inputs explain arithmetic only; they are not a security price, margin requirement or recommended leverage level.
Step-by-step method
- Calculate exposure, financing and initial equity separately.
- Revalue the assets across several adverse price scenarios.
- Express losses relative to contributed capital, including costs separately.
The learner compares an unfinanced PKR 40,000 investment with the teaching financed position. The same percentage price fall has a much larger effect on the financed equity, even before financing charges.
Understand collateral and margin calls
3.1 Mark-to-market and collateral value
Mark-to-market updates exposure using the applicable valuation process. Eligible collateral, haircuts, concentration adjustments and additional requirements affect the margin position. A collateral asset falling alongside the financed shares can worsen the shortfall. A call can require cash, eligible collateral or position reduction within the applicable deadline. Do not assume that a client warning arrives early enough to arrange new funding.
3.2 A threshold is conditional, not a promised exit
For a simplified model with fixed debt D, quantity Q and assumed maintenance equity fraction m, a threshold price is D/[Q×(1−m)]. With the earlier debt and quantity and a purely assumed 30% threshold, this is about PKR 85.71 before interest and costs. Real systems can use different valuation and margin measures, so the formula must not be labelled an NCCPL call-price calculator. Regulatory changes and broker controls may alter requirements.
Step-by-step method
- Identify the actual margin definition and collateral haircuts.
- Calculate a simplified threshold only with stated assumptions.
- Keep a funded response plan and monitor changes in requirements.
If both collateral and the financed share weaken, a worksheet based only on the share price understates pressure. The learner includes both exposures and asks the broker how the actual call is calculated.
Include financing cost and time
4.1 Carry cost changes the break-even
A financed holding has a time-dependent cost in addition to brokerage, taxes and other applicable charges. Read the reference rate, spread, day-count convention, fees and reset mechanism in the actual agreement. A quoted annual rate is not a flat charge on every trade. The funded balance and number of days matter, while capitalised charges can also reduce equity. A share can rise and still leave an unattractive net result.
4.2 Rollover and availability are separate risks
Do not assume financing can be renewed indefinitely. The permitted duration, financier availability, security eligibility and changes in collateral requirements may force reduction at an inconvenient time. Model a delayed exit as well as the planned holding period. Corporate actions require separate review because entitlements, adjusted positions and financing treatment may interact. Compare after-cost outcomes, not simply the share’s gross price change.
Step-by-step method
- Calculate carry using the actual funded balance and contractual convention.
- Add transaction costs and applicable tax separately.
- Stress a longer holding period and unavailable renewal.
A position expected to close quickly remains open because liquidity dries up. The learner adds the extra days of financing and checks whether the cash plan can withstand a margin call before the original investment thesis plays out.
Design controls and an exit process
5.1 Liquidity and execution uncertainty
A stop order is a decision tool, not insurance against loss. A price gap, market halt or lower-price limit can prevent an exit at the intended price. Forced liquidation can occur when many participants seek to sell simultaneously. The loss can exceed the original cash contribution in severe circumstances, depending on the position and terms; borrowing obligations must be understood before entry.
5.2 Reconcile the financing close-out
Set a capital budget, exposure limit and a realistic funding contingency. A plan that relies only on selling collateral during the same stress is weak. After closing, verify the securities sale, repayment, accrued financing, released collateral and remaining charges. Keep written records of disputes or unexplained differences. Choosing not to borrow is a valid conclusion when the obligation cannot be funded independently of a favourable market.
Step-by-step method
- Stress gaps, lower limits and simultaneous collateral declines.
- Define cash resources and authority for a timely response.
- Reconcile the final financing statement and collateral release.
The learner writes a response for a trading halt: confirm official status, check obligations and contact the verified intermediary. Repeatedly submitting orders cannot make an unavailable market provide an assured exit.
Investor equity under a fixed-debt teaching example

| Initial equity at share price 100 | 40,000 PKR |
| Equity at share price 90 | 30,000 PKR |
| Equity at share price 80 | 20,000 PKR |

Frequently asked questions
Is MTS the same as futures?
No. They have different contractual, settlement and funding mechanics.
Does a stop guarantee the maximum loss?
No. Gaps, limits and unavailable liquidity can prevent the planned exit.
Is the teaching30% maintenance fraction an official rule?
No. It is an explicitly assumed input for a simplified formula.
Can an investor lose more than the cash contributed?
Severe adverse moves and financing obligations can produce such outcomes; inspect the actual terms and stress the exposure.
Common pitfalls
| Common mistake | A better approach |
|---|---|
| Using gross share returns | Calculate the return on investor equity after costs. |
| Assuming one universal margin rate | Check current eligibility, haircuts and signed terms. |
| Funding a call with correlated collateral | Stress collateral and the financed asset together. |
| Assuming indefinite renewal | Test a forced repayment date and unavailable financing. |
