Lesson 31
Hedging Equity Portfolios
Protecting a portfolio you do not want to sell — and being honest about what that protection costs.

Keep the shares. Change the downside.

Protect the exposure you actually own
Follow one NIFTY-linked portfolio through a fall, a flat market and a rally. The question to keep asking: how much loss is left after the hedge, including what the hedge cost?
By the end you will be able to answer
- What does the Put buy you?
- How many lots do you need?
- What does a cheaper collar give up?
You hold Indian shares for the long term, but the next few weeks look uncertain and a short-term fall would be hard to sit through. You could sell the shares, which removes the exposure. Or you could buy a Put, which changes the exposure and lets you keep the shares. A hedge is a second position with its own price, its own expiry and its own obligations.
A protective Put pairs something you own with a bought right to sell it at a fixed strike. A NIFTY Put settles against the index instead of your shares. It can offset a broad market fall, but it leaves company-specific losses uncovered. We keep that difference in view the whole way through.
Our constructed portfolio is worth ₹31,85,000 and tracks 130 NIFTY index units exactly, with NIFTY at 24,500. Two assumed 65-unit lots use a 24,300 Put strike and a ₹150 premium per unit. Every price and quantity is made up for teaching, not a live quote. For how a Put works on its own, see the earlier lessons in this series; here we only ask what it does to a portfolio.

What does the Put buy you?
See what a Put gives you and what it costs.
MayaMr. Chartist, I hold shares for the long term but the next weeks look shaky. Should I sell them?
Selling removes the exposure. A protective Put changes it and lets you keep the shares. The Put is a second position with its own price, expiry and obligations.
So I am fully protected?
Not fully. In our example the Puts cost ₹19,500. After a 10% fall the combined loss was still ₹45,500: the 200 points down to the strike, plus the premium.
And if the market does not fall?
The Put expires with no value and you are down the premium. Protection costs money even when you never use it.
A NIFTY Put also settles against the index, not your shares, so company-specific losses stay uncovered.
Mr. ChartistShort answer: a floor under the loss, for a price. The two Puts cover 130 assumed units and cost 150 × 130 = ₹19,500. At expiry each Put pays max(24,300 − final NIFTY level, 0) per unit, so the cash received is that amount × 130. Take off the premium once to get the Put result, then add the change in the portfolio. A gain on the Put does not mean the whole position gained.
The Put offsets a fall below its strike
NIFTY starts at 24,500. A ₹31,85,000 portfolio tracks the index, with 130 Put units held to expiry. Prices are made up; costs and dividends are left out.
Exact expiry arithmetic for the tracking portfolio. The line is the combined result with the Put after its premium; the flat part is the floor. The table beneath also lists the unhedged tracking portfolio.
| Series | NIFTY final settlement level · index points | Combined result · rupees |
|---|---|---|
| Portfolio + purchased Put, after premium | 22,050 | −45,500 |
| Portfolio + purchased Put, after premium | 24,300 | −45,500 |
| Portfolio + purchased Put, after premium | 24,500 | −19,500 |
| Portfolio + purchased Put, after premium | 25,000 | 45,500 |
| Portfolio + purchased Put, after premium | 26,950 | 2,99,000 |
| NIFTY at expiry | Portfolio change | Put cash receipt | Combined result after premium |
|---|---|---|---|
| 22,050 | Portfolio change−₹3,18,500 | Put cash receipt₹2,92,500 | Combined result after premium−₹45,500 |
| 24,500 | Portfolio change₹0 | Put cash receipt₹0 | Combined result after premium−₹19,500 |
| 26,950 | Portfolio change+₹3,18,500 | Put cash receipt₹0 | Combined result after premium+₹2,99,000 |
At 22,050, shares lose ₹3,18,500. The Put receives ₹2,92,500; after its ₹19,500 cost, the combined loss is ₹45,500. The receipt is not the Put’s net profit.
The ₹45,500 floor needs exact index tracking, 130 matched units and the Put held to expiry. A mixed-stock portfolio will not have the same floor.
Say NIFTY falls 10% to 22,050. The tracking portfolio loses ₹3,18,500. The Puts receive ₹2,92,500, and after the ₹19,500 premium they gain ₹2,73,000. The combined loss is ₹45,500. You still bear the 200-point fall down to the Put strike, plus the premium.
If NIFTY ends unchanged, the portfolio is unchanged and the Put expires with no value, so you are down the ₹19,500 premium. If NIFTY rises 10%, the portfolio gains ₹3,18,500, and after the premium you are up ₹2,99,000. Protection changes the downside, and it costs money even when you never use it.
This floor belongs to the tracking model at expiry. Real shares can move differently from NIFTY, change in composition or pay dividends. Before expiry, a Put's price also depends on time, implied volatility, interest rates and how easily it trades, so an index move cannot be turned into a guaranteed sale price for the option.
How many lots do you need?
Work out how many lots to use.
Short answer: start from the value you want to protect, divide by the value of one lot, then round to whole lots and accept the mismatch. Beta is an estimate of how much a portfolio moved with the index over a stated past period. A beta of 1.2 suggests the portfolio moved about 1.2% for each 1% in the index on average in that sample. It is not a promise for each move, it can change, and it leaves company and sector risk unexplained.
The index-equivalent quantity is portfolio value × beta ÷ (index level × lot size). At beta 1, ₹31,85,000 ÷ (24,500 × 65) is exactly two assumed lots. At beta 1.2, the answer is 2.4: two lots under-match, three over-match, and the choice depends on your aim and the cost. A ₹10 lakh portfolio gives only about 0.63 lots, which shows how a minimum lot can be too big for a small portfolio.
This count is a common starting point for a short-futures hedge, and it can describe an expiry Put scenario. It does not make a Put delta-neutral today. Delta measures how the option price reacts to a small move right now. At a supplied delta of −0.40, offsetting 130 index units locally needs 130 ÷ (65 × 0.40) = 5 theoretical Put lots. That has a different cost and a different payoff at expiry from the two-lot example.
Short futures give a roughly straight-line offset and give up the broad-market gains on the matched part. They also need margin and daily cash settlement of gains and losses. Bought Puts keep the upside after the premium, but their protection is curved and runs out at expiry. Name your aim before you compare quantities, and check the real contract and lot size. The 65-unit lot is our assumption. Margin, leverage and pledging covers what a short future ties up.
A notional match is not a delta-neutral hedge
Same portfolio, a beta estimate and an assumed 65-unit lot. Matching value and matching today’s sensitivity are different questions.
31,85,000 ÷ 15,92,500 = 2 lots at beta 1.0
Pairs 130 option units with 130 index-equivalent units for the expiry scenario.
Whole-lot execution needs a choice; neither rounding direction is automatically correct.
130 ÷ (65 × 0.40). It matches today’s sensitivity, not the expiry floor, and must be recalculated after the market moves.
One tile is one assumed lot of 65 units, worth 24,500 × 65 = ₹15,92,500
Name the hedge objective
Notional lots = portfolio value × beta ÷ (index level × assumed lot size)
Local Put-delta lots = portfolio value × beta ÷ (index level × assumed lot size × |Put delta|)
Beta is a past estimate, not a promise. Delta depends on the model and the quote and changes. Buying five lots changes the terminal payoff and the premium cost. Costs and funding are left out.
What does a cheaper collar give up?
See what a cheaper collar gives up.
Short answer: the upside above the Call strike. A collar combines a bought Put and a sold Call against something you own, usually with the same quantity and expiry. The money from the Call helps pay for the Put, but you now owe the Call buyer the gain above the Call strike. The lower net cost is the trade.
Keep the 130-unit tracking model. Buy the 24,300 Put at ₹150 and sell the 25,000 Call at ₹120. The net premium is (150 − 120) × 130 = ₹3,900. Below the Put strike, the combined loss at expiry is ₹29,900. Above the Call strike, the combined gain is ₹61,100. Both include the net premium once, and leave out costs and dividends.
A collar lowers premium and gives up upside
Retain the same tracking portfolio. Buy 130 Puts at strike 24,300 for ₹150 each; sell 130 Calls at strike 25,000 for ₹120 each, with the same expiry.
Exact expiry arithmetic for the tracking portfolio. The flat parts are the floor and the cap. The table beneath lists the Protective Put portfolio and the collar.
| Series | NIFTY final settlement level · index points | Collar result · rupees |
|---|---|---|
| Portfolio + Put + sold Call, after net premium | 22,050 | −29,900 |
| Portfolio + Put + sold Call, after net premium | 24,300 | −29,900 |
| Portfolio + Put + sold Call, after net premium | 24,500 | −3,900 |
| Portfolio + Put + sold Call, after net premium | 25,000 | 61,100 |
| Portfolio + Put + sold Call, after net premium | 26,950 | 61,100 |

| 26,950 | Protective Put portfolio+₹2,99,000 | Collar portfolio+₹61,100 |
The net premium is ₹3,900. In this exact-tracking terminal model the loss below 24,300 is ₹29,900, and the gain above 25,000 is ₹61,100. A large rally no longer increases the combined result.
These bounds hold in the tracking model. An index Call against different shares is a proxy hedge and is not covered by them. Margin, settlement and costs are separate.
These limits hold when the shares and the options match, as in a same-stock collar. NIFTY options against a mixed set of shares form a proxy collar: your shares may not rise enough to offset the sold index Call. Holding assorted shares does not make an index Call covered, and does not remove margin. A lower premium alone therefore does not mean better protection.
Compare strike, expiry, quantity, downside, the upside you give up, and funding, all together. In the figure, blue marks the Call contract and beige marks the Put contract. Neither colour says whether you profit. A Put can make money in a fall, and a short Call limits your gain.
What obligations remain after the hedge is on?
Check the duties that remain after the hedge is on.
Short answer: cash, margin, expiry and tax records do not disappear because the payoff looks protected. NSE NIFTY options are European-style: they are exercised at expiry and settled in cash under the exchange procedures. You can still sell them before expiry, but an early sale is a market trade, not exercise. Individual stock options on NSE are also European-style but settled by delivery, so an exercised long Put can require shares you can deliver. A NIFTY hedge does not deliver your portfolio shares.
Check premium cash, short-option margin, collateral and settlement funds one by one. A portfolio that looks protected at expiry can face cash pressure while the hedge is open. If you close or change one leg, what remains is a new position, and the original collar no longer describes it.
Protection ends when the contract ends. To extend it you must trade again at the terms on offer then. Repeated premiums, spreads and charges reduce your returns. A lower-strike Put may cost less in some comparisons but leaves more downside unprotected, so premium alone does not measure the quality of a hedge.
Tax depends on the facts. Shares held as investments and eligible exchange derivatives can fall into different categories, and shares held in a trading business have their own treatment. Do not assume your hedge result nets off for tax. Keep fills, expenses and settlement records, and check the taxation lessons for the period concerned.
To review, look at both positions at one time: what exposure is left, what it cost, when it expires and what cash or shares are needed. The next lesson asks what happens when the market moves further or faster than any plan assumed. For the basic habit of sizing the loss first, see risk management 101.

Common questions
01What is a protective Put?
It pairs an owned asset with a purchased Put on that asset. At expiry, matched quantity offsets losses below the strike after premium. An index Put against different shares is a proxy hedge and retains mismatch risk.
02Can a NIFTY Put guarantee a floor for mixed shares?
No identical floor follows from an index hedge. Shares can move differently from NIFTY. The worked ₹45,500 floor assumes exact index tracking and matching Puts held to expiry.
03How do I estimate lots using beta?
Divide portfolio value × beta by index level × lot size. The constructed ₹31,85,000 portfolio, beta 1, NIFTY 24,500 and assumed 65-unit lot give two lots. Whole-lot constraints, uncertain beta and the objective remain important.
04Is a beta-based Put quantity delta-neutral?
Not automatically. A local Put-delta offset also uses absolute option delta. At the supplied −0.40 delta, five theoretical lots offset the example’s current sensitivity; the two-lot hedge has an expiry-protection objective. Both sensitivities can change.
05How does a collar differ from a protective Put?
A collar sells a Call to help fund the Put and surrenders upside on the matched exposure. A plain Put pays the full premium and retains upside after cost. A proxy collar retains mismatch and short-option funding obligations.
06Can I exercise an NSE NIFTY Put before expiry?
NIFTY options are European-style and exercised at expiry under applicable procedures. An earlier sale is a market trade subject to liquidity and execution, rather than early exercise.
07Does hedging remove margin and tax requirements?
No. Premium, short-option margin, settlement and records remain separate from payoff. Share and derivative tax categories depend on the activity and applicable law; automatic netting cannot be assumed.
