Married Put

Quick answer: A Married Put is the simultaneous purchase of the underlying and a protective put on it, bought together as one planned position. The put caps the downside at the strike while leaving the upside open, in exchange for the premium paid for that protection.

In simple words

A married put is buying something and buying insurance on it at the same moment, as a single plan. You own the underlying so you keep all of its upside if it rises. The put is your safety net: if the price falls below the put's strike, the put gains value and stops your losses there. The cost of that net is the premium, which lowers your gain if the market rises. It is called married because the two are bought together and treated as one position from the start, unlike a put added later to protect something you already hold.

Professional explanation

One planned position, bought together

The defining feature of a married put is timing and intent: the underlying and the put are bought simultaneously, as a single planned trade, rather than the put being added later to existing holdings. That is the entire distinction from a protective put — the structure and payoff are identical. Framing it as one position matters for how a trader thinks about cost basis: the premium is treated as part of the entry cost of the whole position from the outset. In several texts the married put is also taken to use an at-the-money or near-the-money strike, so the insurance is close to the purchase price and the floor sits just below it.

Where the floor comes from

The long put caps the downside. Below the put's strike, every rupee the underlying loses is matched by a rupee the put gains, so the position's value stops falling. The maximum loss is therefore the distance from the entry price to the strike, plus the premium paid. With the underlying at 24,000 and a 23,800 put costing 240, that floor is (24,000 − 23,800) + 240 = 440 per unit. This is genuinely defined risk, and the cap comes from the put leg, not from the underlying reaching zero — which is what separates a married put from simply owning the underlying outright.

The cost of insurance and the raised breakeven

Protection is not free. The premium raises the breakeven above the entry price: the underlying must rise by the premium before the position turns positive. With a 240 premium, breakeven is 24,240, not 24,000. If the underlying merely drifts sideways, the put decays and the premium is a drag. This is the standing trade-off of insurance — you accept a certain, small cost every period in exchange for capping an uncertain, larger loss. Over many periods the premiums add up, so a married put held permanently is expensive; it is most coherent when a specific downside risk is in view.

The NIFTY practicality problem

You cannot literally buy 'one unit of NIFTY' — the index is not a tradable spot instrument for retail. In practice a trader expressing this would hold NIFTY futures or an index ETF or basket, and buy index puts against it. Substituting futures changes the arithmetic slightly because futures carry embedded financing and roll costs, and an ETF has tracking differences and its own liquidity. So 'long stock at 24,000' here is a stand-in for whichever tradable proxy the trader actually holds. For individual Indian stocks the structure works directly, but note those options are American-style and physically settled.

Construction

1. Buy the underlying — for an index view, a proxy such as NIFTY futures or an index ETF, since spot NIFTY is not tradable by retail.
2. At the same time, buy one put, typically at or near the money, for each unit of the underlying held.
3. The put premium is added to the entry cost; the position is treated as one from the outset.
4. Hold both to the put's expiry, then either let the put lapse, roll it forward, or exit the whole position.

Market outlook

A trader might study a married put when wanting to own the underlying for an expected rise but unwilling to accept its full downside over the holding period — for instance ahead of an uncertain event that could cut either way. Because the buyer is paying for insurance regardless, it does not require low implied volatility the way a speculative long option does, though cheaper protection is naturally preferable. The rationale weakens if the position is held indefinitely, since repeated premiums accumulate into a heavy drag, and it is invalidated if the trader has no genuine wish to own the underlying in the first place.

Risk profile

A married put is a defined-risk position. The maximum loss is the distance from the entry price to the put's strike, plus the premium paid, multiplied by the lot size. That cap comes from the long put, which matches the underlying's losses rupee-for-rupee below the strike — not from the underlying reaching zero, which is what would bound an unhedged long position. This is the key difference from owning the underlying alone: the floor is close and defined rather than distant and notional. The certain cost of that floor is the premium, paid whether or not it is ever needed.

Reward profile

The reward is the underlying's gain above the raised breakeven of entry price plus premium, and it is structurally uncapped because you own the underlying outright — the put does not cap the upside, only the downside. The premium is a fixed drag: the underlying must first rise by the premium to break even, after which every further rupee of the rally accrues in full. In practice the realised reward is the underlying's move minus the cost of the insurance, which is the price of having a defined floor beneath it.

Margin requirement

The put leg is fully paid and needs no margin. The underlying leg is where capital sits: a retail trader cannot hold spot NIFTY, so the position is built on a proxy — index futures, which attract SPAN plus exposure margin, or a fully-paid index ETF or basket. This is why 'long stock at 24,000' is a stand-in for whatever tradable instrument is actually held. Futures margin can rise with volatility, and brokers and NSE revise margin rules periodically; an ETF ties up its full value but faces no margin call.

Greeks exposure

The sign on each Greek above is computed, not asserted: it is the net exposure of the illustrative legs at spot 24,000 with 30 days to expiry, priced with Black–Scholes using each leg's implied volatility calibrated from its own quoted premium. A sign can flip as the underlying moves — the panels below show where. See Methodology.

Volatility impact

Rising implied volatility increases the value of the protective put, which can lift the whole position's mark even before the underlying moves, and makes the insurance worth more precisely when markets are unsettled. Falling volatility reduces the put's value and is a drag. Unlike a speculative long option, a married put is not primarily a volatility bet — the buyer is paying for protection regardless — but the entry cost still depends on volatility: buying the put when implied volatility is elevated means paying more for the same floor. After a known event the volatility crush lowers the put's value, so protection bought cheaply before a spike is more economical than protection bought into one.

Time decay

Theta works against the put leg, and that decay is simply the cost of insurance accruing over time. An at-the-money put decays slowly at first and faster as expiry nears, so a married put held to expiry surrenders the remaining time value if the protection is not used. The underlying's gains are not subject to decay — only the put is — so the drag is bounded by the premium. Rolling the put forward to maintain protection means repeatedly paying this decay, which is why a permanently insured position is costly to run.

Practical examples

Lot sizes used above (NIFTY 75, BANKNIFTY 30) are those in force at the time of writing; NSE revises them periodically. Figures exclude brokerage, STT, exchange charges, stamp duty and GST, all of which materially affect small spreads.

Common mistakes

• Running a married put permanently, so repeated put premiums accumulate into a heavy drag that quietly erodes the underlying's returns over time.
• Treating 'long NIFTY at 24,000' as literal, when spot NIFTY is not tradable — the position must be built on futures or an ETF, each with its own carry or tracking cost.
• Buying the protective put into a volatility spike, paying an inflated premium for a floor that could have been set far more cheaply beforehand.
• Forgetting that the premium raises the breakeven, so a small rise that would profit an unhedged holder still leaves the married put underwater.
• Choosing too low a put strike to save premium, which widens the floor and leaves a larger uninsured loss between entry and the strike.
• On single stocks, ignoring that American-style options are physically settled, so an exercised put means delivering shares rather than a cash adjustment.

Advantages & disadvantages

Adjustments & exits

• A trader may roll the put forward at expiry to maintain protection, paying a fresh premium each time — the running cost of keeping the floor in place.
• Rolling the put up after a rally raises the floor to lock in some gains, at the cost of a higher premium for the closer strike.
• Selling a higher call against the position converts it into a collar, financing the put with call premium but capping the upside in return.

Adjustment is a decision about risk, not a way to rescue a losing view. See Adjustments and Exit Planning.

Professional usage

Portfolio managers use this concept as tail insurance rather than a standalone trade: index puts are bought against a long book to define the worst case over a specific window, such as an election or a policy meeting. At institutional scale the protection is often financed by selling upside — a collar — or funded from a volatility budget, and the puts are chosen on the skew that offers the least costly floor. Retail traders can borrow the framing but not the financing efficiencies; for an individual, the honest version is holding an index ETF or futures proxy and paying full premium for the put.
