Prepare for NISM-Series-VIII by connecting pricing, strategy, and post-trade mechanics into one chain of reasoning: compute cost-of-carry and basis before judging futures quotes, decompose every option premium into intrinsic and time value, match each named strategy to a view on direction, volatility, and time, then trace the resulting position through daily mark-to-market, margin, and settlement rules before applying the regulatory and tax frame.
Why futures trade above or below spot: pricing the basis correctly
A futures price reflects the spot price plus the cost of carry; the gap is the basis. Pricing questions test whether you can compute fair value from carry assumptions and interpret premium or discount, not whether you remember a formula.
Cost of carry includes financing the underlying until expiry and adjusts for income such as dividends. When carry is positive, futures normally trade above spot (contango); negative carry or heavy expected dividends can push them below (backwardation). Basis, defined as spot minus futures, shrinks toward zero at expiry because convergence is mechanical. Practice computing fair value as F = S x (1 + r x t) minus dividends for a stated annualised rate and day count, and practise converting days to a fraction of a year correctly.
Worked scenario: spot is 1,000, the 30-day futures trades at 1,010, annualised carry is 9%, and no dividend is due. Fair value is about 1,000 x (1 + 0.09 x 30/365) = 1,007.4. The plausible mistake is seeing the 10-point premium and concluding that buying spot and selling futures locks in 10 points of profit. The better decision is to net the funding cost first: the gross spread is roughly 2.6 points, which transaction costs can erase entirely. This matters because the same arithmetic — carry first, then judgement — drives pricing and arbitrage questions throughout the syllabus.
Separating intrinsic value from time value before choosing an option
Every option premium splits into intrinsic value, the amount realisable by immediate exercise, and time value, everything above that. Moneyness is defined by strike versus spot separately for calls and puts.
For a call, intrinsic value is the excess of spot over strike, floored at zero; for a put it is the excess of strike over spot. Time value equals premium minus intrinsic value and is typically largest for at-the-money strikes, decaying as expiry approaches. Distinguish the right to exercise from the decision to exit: European-style options can be exercised only at expiry, so before expiry your exit is a squaring-off trade at market price, not an exercise. Indian index options follow the European style; carry that distinction into every exercise-versus-sell question.
Micro-example: an index stands at 21,800 and a 21,600 strike call trades at 300. Intrinsic value is 200 and time value is 100. A plausible mistake is labelling the option out of the money because the premium feels expensive relative to the strike gap. The better decision is to classify moneyness strictly by strike against spot — the call is in the money — and then ask whether the 100 points of time value is defensible given the days remaining. This decomposition matters because break-even and strategy profit-and-loss questions build directly on it.
Matching a strategy to a view, not to the premium collected
Each named strategy is a combined exposure to direction, volatility, and time decay. Select by matching those exposures to your view and risk budget, and read the payoff extremes from the diagram rather than from the cash premium.
A covered call is long stock plus a short call: premium received, upside capped at the strike, full stock downside retained. A protective put is long stock plus a long put: premium paid, downside floored near the strike, upside retained. Vertical spreads pair a long and a short option to cut cost and cap both outcomes. A long straddle buys both an at-the-money call and put, betting on movement; a short straddle collects premium and bets on stillness. Build each payoff diagram with maximum profit, maximum loss, and break-even points labelled before evaluating the position.
Worked scenario: a trader expects a stock to stay flat through results and sells a straddle for 120 points of combined premium. The plausible mistake is treating the 120 as income without pricing the unbounded loss if the stock gaps and without checking that short-option margins can be funded through an adverse move. The better decision is to stress the position across a range of prices, or to use a defined-risk structure with long wings so the maximum loss is known in advance. This distinction matters because strategy questions reward identifying which leg creates the unbounded exposure.
| Strategy | Market view | Maximum profit | Maximum loss | Key trade-off |
|---|---|---|---|---|
| Covered call | Neutral to mildly bullish | Stock gain to strike plus premium received | Stock downside less premium received | Upside is capped |
| Protective put | Bullish but risk-averse | Unlimited above strike, less premium paid | Stock fall to strike plus premium paid | Insurance has a running cost |
| Bull call spread | Moderately bullish | Strike width less net premium paid | Net premium paid | Both ends defined |
| Long straddle | Large move either way | Unlimited on the strong leg | Total premium paid | Movement must outrun time decay |
Tracking daily cash flows: mark-to-market, SPAN and settlement obligations
Exchange-traded derivative positions are marked to market daily and margined upfront. SPAN estimates portfolio risk across scenarios; additional margins cover residual risk; obligations arise from daily settlement prices, not just realised profit.
Mark-to-market means each day's positions are effectively revalued at the settlement price, and the resulting loss must be met by the prescribed time, while gains are credited. Margin for a portfolio is computed through SPAN's scenario-based risk array, with additional margins layered on; short options attract substantial risk margins because their loss profile is open-ended. Knowing which cash flow happens daily, which is blocked as margin, and which settles only at expiry is the skill this part of the syllabus tests.
Paper observation: a practice account shorts a stock option at a 40-point premium and the underlying rises 6% over several sessions. The position shows a growing daily mark-to-market debit and a margin top-up request far exceeding the 40 points collected. The planning mistake is budgeting only the premium received; the better decision is to model worst-case daily losses within your exercise. Self-check: for any position you construct, you should be able to state which cash flows occur on day one, each day thereafter, and at expiry.
From order to final settlement: how a trade actually closes out
Trade-lifecycle questions follow a fixed path: order placement and types, matching on the exchange, clearing through the corporation, and settlement in cash or by delivery, with style varying by product.
Index derivatives in India settle in cash against the final settlement price, while single-stock futures can involve delivery obligations at expiry, so holding through expiry has different consequences for each. Most positions are closed early by an offsetting trade, which is why squaring off — not exercise — is the normal exit. Know the common order types: limit orders specify a price, market orders execute immediately at available prices, and stop-loss orders convert once a trigger is reached; each fits a different execution problem.
A decision point worth practising: you hold an in-the-money index option near expiry. The plausible mistake is assuming the settlement value equals the last traded price you saw on screen. The better decision is to reason with the final settlement price mechanism for the product and to compare squaring off in the market against holding to expiry settlement, including time value that would be forfeited on early exercise of a European option. This matters because lifecycle questions test whether the mechanics you describe belong to the specific product in the stem.
Regulatory boundaries and how your derivative profit and loss is treated
SEBI regulates exchange-traded equity derivatives through recognised exchanges and clearing corporations, within approved segments and position limits; income from such trading is generally treated as non-speculative business income.
The regulatory frame operates in layers: the SEBI framework, exchange bylaws, and clearing corporation rules together govern who may trade, in which segments, with what client-level identification and position limits, under surveillance mechanisms. Derivatives are presented as legitimate hedging and trading instruments, not as prohibited speculation — the regulatory question is whether activity and participants fit the approved structure. Learn the roles of each institution and which rule sits at which layer, rather than treating all limits as one undifferentiated list.
On accounting and tax, a trader's premiums paid and received and daily mark-to-market flow through the profit and loss account, and exchange-traded equity derivatives income is treated as non-speculative business income, so related business expenses are claimable — a contrast worth holding against speculative-income rules. Separate this from hedge accounting under accounting standards, which is a corporate-reporting concept about designating and documenting hedging relationships. The exam distinction is whose books you are looking at: an individual trader's tax position or a company's hedged accounting treatment.
A four-week practice sequence with a payoff-diagram exercise and readiness checks
Sequence preparation so pricing feeds strategy and strategy feeds post-trade decisions: carry and basis first, then option decomposition, then strategies with margin effects, then regulation, accounting, and mixed timed practice.
A four-week sequence you can compress or extend: week one, futures pricing — compute fair value, basis, and convergence for at least ten varied stems; week two, options — decompose premiums across five strikes and sketch single-leg payoffs; week three, strategies and margins — build multi-leg diagrams and add daily mark-to-market tracking for each; week four, regulation and accounting plus full mixed timed sets with an error log sorted by topic. Keep every calculation closed-book from week two onward so retrieval, not recognition, is what you practise.
Exercise: invent a stock with a spot of 500 and a fictional 30-day series. Write the intrinsic and time value for five strikes, sketch payoffs for a covered call, protective put, bull call spread, and long straddle, then compute daily mark-to-market for a three-day price path you design. Rubric for the exercise: the intrinsic-plus-time-value components sum to each premium; each payoff diagram labels maximum profit, maximum loss, and break-evens; the mark-to-market table identifies daily obligation versus expiry settlement; and you complete each payoff sketch within a set time you choose as a milestone. Treat resulting scores as learning signals, not pass predictions.
Readiness checks before you sit any practice set: compute fair value and basis for a fresh stem in about a minute; classify moneyness and decompose a premium on sight; reproduce each core strategy's payoff extremes from memory; narrate the order-to-settlement workflow for both an index and a single-stock position without notes; and state which layer — SEBI, exchange, or clearing corporation — owns a given rule.
- Carry arithmetic: convert annualised rates and day counts without a formula sheet
- Premium decomposition: intrinsic plus time value reconciles exactly for every strike
- Payoff construction: maxima, minima, and break-evens labelled on every diagram
- Cash-flow mapping: daily mark-to-market, upfront margin, and expiry settlement kept distinct
- Rule placement: SEBI, exchange, and clearing-corporation responsibilities attributed correctly
