The Collar Strategy in Indian Markets: Correct Lots, Real Examples, and Tax Rules

What a Collar Actually Is

A collar is a three legged position. You already own the underlying, you buy a protective put with a strike below the current price, and you sell a covered call with a strike above the current price. The put gives you the right to sell at a fixed floor, so your loss below that floor stops. The call obliges you to deliver at a fixed ceiling, so your gain above that ceiling stops. Between the two strikes your position behaves almost exactly like the underlying you hold.

The reason traders use collars is cost. A naked protective put is expensive insurance. By selling a call against your long, the premium you collect pays for most or all of the put, so you get downside protection for little or no net cash outlay. The trade off is that you sign away the upside above the call strike. You are renting out the top of your gains to fund the bottom of your protection.

In Indian markets this is run on two very different kinds of underlying, and the distinction matters for the maths. On a single stock in the F&O list, such as Reliance, HDFC Bank, TCS, or Infosys, you can hold the actual shares and write listed options on them. On an index such as Nifty 50 or Bank Nifty, you do not own shares at all. You hold the exposure through index futures or an ETF and overlay index options. Getting this wrong is the single most common error in beginner explanations of the collar.

You Cannot Own Nifty Units: Fixing a Common Error

Many guides casually say you can buy a put and sell a call on the Nifty 50 units you own. This is wrong. Nifty 50 is an index, a number, not a tradeable share. There is no such thing as one Nifty unit you can hold in your demat account. When someone owns Nifty exposure, they hold it in one of three real instruments, and your collar has to be built around whichever one you actually have.

• Nifty index futures: one lot is 65. Holding one Nifty future at, say, 23,500 gives you exposure of 23,500 times 75, which is roughly Rs 17.6 lakh of notional, controlled with margin, not the full cash.
• A Nifty ETF such as Niftybees: here you do own units in demat, each unit tracking roughly one hundredth of the index. But ETF lots and option lots do not line up cleanly, so this is a loose hedge, not a precise one.
• Nifty index options themselves: the option lot is also 65, matching the futures lot, so options collar neatly against a futures position.

The practical upshot is that an index collar is almost always futures plus options, with everything in multiples of 75 for Nifty, 15 for Bank Nifty, 25 for FinNifty, and 10 for Sensex. The old worked example that talked about a maximum loss of Rs 500 per Nifty unit was meaningless, because there is no unit and because index option premiums are quoted in points that must be multiplied by the lot of 75. Below we replace it with correct maths.

Worked Example One: A Collar on Reliance Shares

Suppose you hold 500 shares of Reliance Industries bought at Rs 1,400, now trading at Rs 1,500, so you are sitting on a paper profit. Reliance has a monthly F&O lot, and the current lot size is 500 shares, so your holding is exactly one lot. You expect Reliance to drift sideways to mildly up into the next monthly expiry but you are nervous about a sharp fall, so you build a collar. All figures are illustrative.

• Long: 500 Reliance shares at current price Rs 1,500.
• Buy 1 lot of the 1,440 put for a premium of Rs 22 per share. Cost: 22 times 500 equals Rs 11,000.
• Sell 1 lot of the 1,560 call for a premium of Rs 20 per share. Credit: 20 times 500 equals Rs 10,000.
• Net option cost: Rs 11,000 minus Rs 10,000 equals Rs 1,000 paid, before charges.

Now trace the outcomes at expiry on the full 500 share lot. If Reliance crashes to Rs 1,380, your shares lose Rs 120 each, but the 1,440 put lets you sell at 1,440, so your effective floor is 1,440. Your worst case on the share side is a fall from 1,500 to 1,440, which is Rs 60 per share, or Rs 30,000 across 500 shares, plus the Rs 1,000 net option cost, for a maximum loss of about Rs 31,000 before charges. Without the collar a drop to 1,380 would have cost you Rs 60,000 on the shares alone, so the put has cut the bleeding roughly in half.

If instead Reliance rallies to Rs 1,620, your shares gain Rs 120 each, but the 1,560 call you sold is now in the money and you are assigned, so your shares are effectively sold at 1,560. Your gain is capped at a rise from 1,500 to 1,560, which is Rs 60 per share, or Rs 30,000, minus the Rs 1,000 net option cost, for a maximum profit of about Rs 29,000 before charges. Between 1,440 and 1,560 the shares move freely and the options expire worthless, leaving you only the Rs 1,000 net option cost. The collar has boxed your outcome into a tight, known range.

Worked Example Two: A Collar on a Nifty Futures Position

Now the index, done correctly. Suppose you are long one Nifty futures lot, lot size 65, entered at 23,500. You are mildly bullish into monthly expiry but want a defined floor ahead of an RBI policy meeting. You build a collar entirely in index options of the same 75 lot. Premiums are in index points and must be multiplied by 75. All numbers are illustrative.

• Long: 1 Nifty future at 23,500, lot size 65.
• Buy 1 lot of the 23,200 put for 90 points. Cost: 90 times 75 equals Rs 6,750.
• Sell 1 lot of the 23,800 call for 80 points. Credit: 80 times 75 equals Rs 6,000.
• Net option cost: Rs 6,750 minus Rs 6,000 equals Rs 750 paid, before charges.

If Nifty falls to 23,000 by expiry, the future loses 500 points, but the 23,200 put gains, so your floor is 23,200. The worst case on the futures leg is a fall from 23,500 to 23,200, which is 300 points, or 300 times 75 equals Rs 22,500, plus the Rs 750 net option cost, for a maximum loss near Rs 23,250 before charges. If Nifty rallies to 24,000, the future gains but the 23,800 call caps you, so your ceiling is 23,800. The best case is a rise of 300 points, or Rs 22,500, minus the Rs 750 net cost, for a maximum profit near Rs 21,750. Note how every figure is a point value times the lot of 75, never a per unit rupee figure.

Reading the Collar Payoff

The collar payoff is flat at the bottom, sloped in the middle, and flat at the top. Below the put strike you are fully protected and your loss stops. Between the two strikes you participate one for one with the underlying. Above the call strike your gain stops because you have effectively pre sold at the ceiling. The width between the strikes is the range in which you keep real exposure, so a wide collar behaves more like the raw stock and a tight collar behaves more like a fixed deposit with a small spread.

Two design choices control the shape. The put strike sets how much pain you accept before protection kicks in, like the deductible on an insurance policy. A put closer to the current price costs more but limits the gap. The call strike sets your ceiling, and a call closer to the current price brings in more premium but caps your upside sooner. A zero cost collar is when you push the call in just enough that its premium fully pays for the put.

Entry, Exit, and Adjustment Rules

Enter a collar when you already hold the underlying, you are mildly bullish to neutral, and you want a known worst case over a defined window, typically into an expiry, a result, or a macro event. A clean default is to buy a put a few percent below spot and sell a call a few percent above, sized so the net cost is small. Choose strikes with real liquidity. On Nifty and Bank Nifty the round strikes around spot are deeply liquid, while on single stocks only the near the money strikes of the most active names like Reliance, HDFC Bank, and Infosys trade tightly.

• Exit at expiry and let the options settle if price is comfortably between the strikes and you still want to hold the underlying.
• Close early if the underlying jumps to the call strike and you would rather keep the shares than be assigned. You buy back the call, usually at a loss, and decide whether to re collar higher.
• Roll the collar if your view extends past the current expiry. You close both option legs and open the same structure in the next series, paying fresh time value.
• If the underlying collapses to the put strike, the put has done its job. You can exercise or sell the in the money put to bank the protection, then reassess the share position.

The collar is self hedging, so it does not need a separate stop loss in the usual sense. The put strike is your stop, defined in advance and guaranteed by the option, rather than a level you hope to exit at in a fast market. That certainty is the whole point. The cost is that you have also pre committed your exit on the upside through the short call.

Best Market Conditions, and When to Avoid It

Collars shine when you are mildly bullish but worried about a near term shock. Classic Indian setups are holding a large stock position into its quarterly results, holding index futures through the Union Budget or an RBI policy decision, or protecting a gain you do not want to give back before the financial year ends. In all of these you want to stay invested but you want a hard floor for a few weeks.

Collars are a poor fit when you are strongly bullish, because the short call will cut off exactly the rally you were hoping for. They are also weak when implied volatility is very low, because the call you sell brings in little premium, so the put is barely subsidised and the structure costs more than it is worth. And on illiquid single stock options the bid ask spread can quietly eat more than the protection saves, so stick to the most traded F&O names for stock collars.

Costs: Brokerage, STT, and Other Charges

A collar has three legs and each leg carries its own charges, so always net them against the small edge a tight collar offers. On the option legs the big one is Securities Transaction Tax. For options, STT is charged at 0.1 percent on the sell side premium, and on options that are exercised STT is charged on the intrinsic settlement value. The call you write and any put you sell to close both attract STT on the sell premium. On the underlying shares, delivery STT is 0.1 percent on both buy and sell.

• Brokerage: most discount brokers charge a flat fee per executed order, often around Rs 20 per order, so three legs means roughly three fees each way.
• STT on options: 0.1 percent on the sell side option premium, plus STT on intrinsic value if an option is exercised.
• Exchange transaction charges, SEBI turnover fees, stamp duty on the buy side, and 18 percent GST on the brokerage and transaction charges.
• On the shares leg, delivery STT of 0.1 percent each way plus the usual demat and DP charges on sale.

Because the net edge on a tight collar can be a few hundred or a few thousand rupees, these charges are not a rounding error. In the Reliance example the net option cost was Rs 1,000 before charges, and brokerage plus STT plus GST across the legs could easily add a few hundred rupees more, meaningfully changing the breakeven. Always price the collar after charges, not before.

Tax Treatment in India: The Real Rules

Here the old version of this page was simply wrong, and the correction matters for your return. It claimed that the premium you collect from writing a call is taxed as Income from Other Sources. That is not how Indian law treats F&O. Gains and losses from trading futures and options, including writing options, are treated as non speculative business income under the Income Tax Act. They are reported on your business income schedule and taxed at your applicable slab rate, not under Income from Other Sources and not as capital gains.

This has real consequences. Because F&O is business income, you can set off F&O losses against other non speculative business income, carry forward unabsorbed F&O losses for up to eight years if you file your return on time, and claim genuine trading expenses. The put and the call legs of an index or stock options collar both fall under this F&O business income head, not under two different heads as the old page suggested. There is no separate Other Sources bucket for the call premium.

The underlying leg is taxed differently from the option legs. If you hold actual Reliance shares and sell them, that sale is a capital gain. After the Budget 2024 changes, short term capital gains on listed equity are taxed at 20 percent and long term capital gains are taxed at 12.5 percent on the amount above Rs 1.25 lakh per year. A holding of more than twelve months is long term. So a stock collar can mix two tax heads, business income on the options and capital gains on the shares, while a pure index futures and options collar sits entirely under F&O business income. Tax rules change, so confirm current rates with the Income Tax Department or a qualified advisor before you file.

Common Mistakes to Avoid

• Thinking you can own Nifty units. The index is a number. Hold futures, an ETF, or use index options, all in lots of 65 for Nifty.
• Quoting index option premiums as rupee per unit. They are points, multiplied by the lot of 75, 15, 25, or 10.
• Assuming the call premium is Income from Other Sources. F&O, including option writing, is business income taxed at your slab rate.
• Picking illiquid stock option strikes where the spread quietly costs more than the hedge saves.
• Forgetting STT, brokerage, and GST across three legs, then being surprised the net edge vanished.
• Using a collar when you are strongly bullish, then complaining that the short call capped exactly the rally you wanted.

Most of these mistakes come from copying a generic global explanation of the collar without adjusting for Indian contract specifications and tax law. Build the structure around the real instrument you hold, size every leg by the correct lot, and account for charges and the F&O business income treatment before you decide the collar is worth it.
