Exchange-Traded Derivatives in Practice: Margins, Expiry, Tax and Portfolio Uses

Learning objectives

By the end you can:

1. Read a contract specification as a primary source and extract the five parameters that must be known before sizing anything: multiplier or lot size, tick and tick value, expiry date and time, settlement style and exercise style, with a verify flag on every perishable figure.
2. State what compulsory physical settlement of Indian single-stock derivatives does to an in-the-money position, compute the delivery obligation at full contract value, and tabulate the staged delivery-margin ramp across expiry week in rupees.
3. Build a margin requirement from its parts: a SPAN-style scanned risk over a sixteen-scenario array, the exposure margin, the net option value credit, and the expiry-day add-on, then convert the total into a gross-notional and a delta-equivalent leverage figure and say which one is honest.
4. Compute the total statutory and exchange cost of an Indian derivatives round trip, including the securities transaction tax asymmetry between selling an option and letting it settle, and state the break-even move that cost implies.
5. Classify exchange-traded derivative income under the Section 43(5)(d) carve-out, compute turnover on the current guidance basis, test it against the tax-audit threshold, and apply the set-off and eight-year carry-forward rules correctly against speculative and non-speculative losses.
6. Contrast the US regime: 100-share American equity options, the early-exercise decision around a dividend computed from the put price and the interest saved, cash-settled index options, assignment mechanics, and the 60/40 treatment of Section 1256 contracts.
7. Adjust a portfolio's equity beta to a stated target with index futures, equitise a cash balance, and decompose the tracking difference into entry richness, contract rounding and unrebalanced overlay drift so that every dollar of residual has a name.
8. Move duration with bond futures and run a two-legged asset-allocation switch, comparing the overlay's cost and residual against the physical trade it replaces.
9. Set currency hedging as a policy decision rather than a trade: place a mandate on the hedge-ratio spectrum, roll a forward hedge across four quarters, and separate the knowable carry from the unknowable spot move.
10. Explain how a volatility index is built, why a constant-maturity long-volatility product decays in a static contango curve, compute that decay over one roll cycle, and say what a variance swap does differently.

The gate rewards the by-hand versions of all ten. A margin figure, a turnover figure and a contract count are exactly the outputs that a model produces fluently and gets wrong silently, so the productivity payoff at the end of this node is conditional on being able to reproduce each of them on paper first.

Prerequisites & connections

Builds on. The derivatives branch supplies the pricing. Cost of carry, futures mark-to-market and the initial-versus-maintenance margin sequence come from the forwards and futures node. Option pricing, parity and the Greeks come from the options node. Payoff construction, delta and gamma hedging, the beta-adjustment formula and the basis-point-value hedge come from the option-strategies node, which also states the minimum-variance hedge ratio used here without re-deriving it. DV1.04: Swaptions, the Black Model and Non-Rate Swaps is the immediate predecessor and owns the exchange-against-over-the-counter comparison, the central counterparty and novation, the clearing-member default waterfall, and the taxonomy that separates forward commitments from contingent claims. Read it first if you have not: this node assumes you already know what a clearing house is and starts from what it charges you. From the analyst core, market microstructure, the order book and settlement cycles come from the capital-markets node, and the Indian and US transaction-cost stacks come from the toolkit node.

Feeds forward. The allocation branch consumes these overlays directly, because a policy portfolio that rebalances with futures needs the contract counts and the residuals computed here. The alternatives branch reuses the roll-yield machinery in the volatility section, which is the same arithmetic as a commodity index's negative roll return under a different name. The personal-finance node owns capital-gains tax on securities for an individual investor and receives the business-income treatment from here as its complement.
