Hedging in Indian Markets: A Practical Guide With a Worked Nifty Put Example

What Hedging Actually Means

Hedging is the act of opening a second position that moves in the opposite direction of your main holding, so that a loss on one side is softened by a gain on the other. If you own a basket of stocks that track the Nifty 50, your worry is a market crash. A hedge is something that pays you when the market crashes, for example a Nifty put option. You are deliberately giving up a small, known amount of money now to cap a large, unknown loss later.

The key mental model is car insurance. You pay a premium every year. Most years nothing happens and the premium is gone. But in the one year you have an accident, the payout dwarfs all the premiums you ever paid. Hedging works the same way. You should expect most hedges to expire worthless, and that is fine, because the point is protection against the rare large drawdown that can ruin a portfolio.

This is different from speculation. A speculator buys a put because they expect the market to fall and want to profit from it. A hedger buys the same put because they hold something else that suffers if the market falls, and they want to neutralise that pain. The instrument is identical. The intent and the position behind it are what make it a hedge.

Why Indian Traders Hedge

Indian equity portfolios are heavily concentrated in a few large indices and sectors. A typical retail portfolio of banking, IT and large-cap stocks behaves a lot like the Nifty 50 itself. That makes index hedges very effective, because one Nifty put can cover the downside risk of a whole basket of correlated stocks without you having to hedge each stock separately.

Events also cluster in India. Union Budget day, RBI policy announcements, general election results and quarterly earnings seasons can all move the index sharply in a single session. Traders frequently buy short-dated hedges going into these events and let them expire once the uncertainty passes. The weekly and monthly options expiry structure on the NSE makes it cheap and easy to buy protection that lasts only as long as the event risk.

Worked Example: Protecting a Nifty Portfolio With a Put

Suppose Nifty is trading at 24,000 and you hold roughly Rs 18 lakh of large-cap stocks that closely track the index. You are worried about a sharp fall over the next few weeks, so you decide to buy one lot of a Nifty monthly put. All numbers below are illustrative and meant to show the method, not a forecast.

• Instrument: Nifty 24,000 monthly put (at-the-money).
• Lot size: 65 units per lot (current NSE Nifty F&O lot size).
• Quoted premium: assume Rs 240 per unit.
• Premium paid for one lot: 240 multiplied by 65 = Rs 15,600.
• This is the maximum you can lose on the hedge. The put cannot cost you more than the premium.

Now work out the breakeven on the put itself. A put becomes profitable only once Nifty falls below the strike by more than the premium paid. Breakeven = strike minus premium = 24,000 minus 240 = 23,760. Below 23,760 the put is making net money for you. Between 23,760 and 24,000 the put has some intrinsic value but you have not yet recovered the full premium. Above 24,000 the put expires worthless and you lose the entire Rs 18,000.

Say Nifty falls to 23,000 by expiry. The put is now worth its intrinsic value of 24,000 minus 23,000 = 1,000 points. In rupees that is 1,000 multiplied by 75 = Rs 75,000. Subtract the Rs 18,000 premium you paid and the hedge has delivered a gross gain of Rs 57,000. Meanwhile your Rs 18 lakh stock basket fell roughly in line with the index, about 4.2 percent, a paper loss near Rs 75,000. The put has offset most of that drawdown, which is exactly what a hedge is supposed to do.

Reading the Payoff: Costs, STT and Tax

The Rs 57,000 figure above is before costs. Real-world charges shrink it, and you must account for them. On options the big one is STT (Securities Transaction Tax). STT on the sell side of options is 0.1 percent of the premium value, and crucially, if you let an in-the-money option expire instead of squaring it off, STT is charged on the much larger settlement (intrinsic) value, not the small premium. Many traders lose a chunk of profit simply because they forgot to sell before expiry and got hit with STT on the full intrinsic value.

Then comes tax. Gains and losses from F&O, including hedges, are treated as non-speculative business income in India, not as capital gains. That means the net profit is added to your other income and taxed at your applicable slab rate. It does not get the 20 percent STCG or 12.5 percent LTCG treatment that applies to delivery equity. The flip side is helpful: if your hedge expires worthless, that premium loss is a genuine business loss that can be set off against other business income and, subject to the rules, carried forward.

Common Hedging Strategies in India

There is no single hedge that fits everyone. The right structure depends on how much you are willing to spend, how much downside you can tolerate and whether you are protecting a long portfolio or a short one. Below are the structures Indian traders use most often, from simplest to more advanced.

• Protective put: buy a put against stock or index holdings. Simple, defined cost, unlimited upside on your stocks still intact. The example above is a protective put.
• Covered call: hold the stock and sell a call against it. The premium received cushions a small fall, but your upside is capped at the strike. It is a partial hedge, not full protection.
• Collar: buy a protective put and fund it by selling a call. This reduces or even cancels the net premium, but you give up upside above the call strike. Popular for protecting large, profitable positions cheaply.
• Index futures short: sell Nifty or Bank Nifty futures against a long equity basket. This neutralises direction completely, but it also cancels your upside and requires margin and daily mark-to-market.
• Bear put spread: buy a put and sell a lower-strike put to lower the cost. Cheaper than a plain put, but the protection stops at the lower strike.

Notice the trade-off running through all of these. The cheaper the hedge, the more upside or protection you usually give up. A bare protective put costs the most premium but keeps all your upside. A collar is almost free but caps your gains. There is no free lunch, only a choice about which risk you most want to remove.

Hedging With Futures Versus Options

Both futures and options can hedge, but they behave very differently and the choice matters. Shorting a futures contract gives you a linear, symmetric hedge: every point the index falls, your short future gains the same, and every point it rises, your short future loses the same. It costs no premium, only margin, but it removes your upside entirely and exposes you to daily mark-to-market swings that can trigger margin calls.

Buying a put gives you an asymmetric hedge: you are protected if the market falls, but you keep your upside if it rises, because the most you can lose on the put is the premium. That optionality is exactly why puts cost money upfront while futures do not. If you are confident the market will fall, futures are cheaper. If you want protection but still hope the market rises, a put is usually the better fit.

Sizing the Hedge: Getting the Quantity Right

The single biggest practical error is buying the wrong quantity. To size a hedge, first work out the rupee value you want to protect, then divide by the rupee value covered by one lot. With Nifty near 24,000 and a lot of 65 units, one lot covers a notional of 24,000 multiplied by 65 = Rs 15.6 lakh. So a Rs 15.6 lakh basket is hedged by roughly one Nifty lot. A Rs 31.2 lakh basket would need about two lots, and a Rs 7.8 lakh basket is over-hedged by a full lot, which is the smallest unit you can trade.

Because you cannot buy a fraction of a lot, perfect hedges are rare for smaller portfolios. A Rs 9 lakh holding hedged with one Nifty lot is hedging twice the exposure, so a market fall could leave the put gaining more than the portfolio loses, while a rally costs you the full premium on double the size. For smaller accounts, instruments with smaller lot notional or the use of a partial bear put spread can give a tighter fit.

• Step 1: Estimate the rupee value of the holding you want to protect.
• Step 2: Compute one lot notional = index level multiplied by lot size (Nifty 65, Bank Nifty 30, FinNifty 60, Sensex 20).
• Step 3: Number of lots = portfolio value divided by one lot notional, rounded to the nearest whole lot.
• Step 4: Adjust for beta. If your basket is more volatile than the index, you may need slightly more cover.

Expiry Mechanics That Affect Your Hedge

Indian index options have both weekly and monthly expiries, and the difference matters for hedging cost. Weekly options are cheaper in absolute rupees because they have little time left, which makes them ideal for hedging a single event like a budget or a result. Monthly options cost more but give you weeks of protection and decay more slowly day to day. Choose the expiry that just covers the period you are worried about, and no longer, so you do not overpay for time you do not need.

Be aware of time decay, the steady loss of an option's value as expiry approaches. A hedge held through a quiet period bleeds premium even if nothing bad happens. This is the ongoing cost of insurance. It also means a put bought too far ahead of an event wastes money during the calm before it. SEBI and the exchanges periodically revise expiry-day schedules and contract specifications, so always confirm the live expiry calendar and lot size on the NSE before you place the trade.

Common Hedging Mistakes

Most hedging failures are not exotic. They come from a handful of avoidable errors, usually around cost, sizing and timing. Knowing them in advance is half the battle.

• Treating a hedge like a bet. If you secretly want the hedge to pay off, you are speculating. A working hedge that expires worthless because the market rose is a success, not a loss.
• Ignoring the premium drain. Continuously buying protection without measuring the annual premium cost can quietly cap your returns. Budget for it.
• Wrong lot quantity. Forgetting that the payoff is per unit multiplied by 75 leads to hedges that are far too large or too small for the exposure.
• Letting in-the-money options auto-expire. This triggers STT on the full intrinsic value and can erase a meaningful slice of the gain.
• Hedging the wrong instrument. Using a Nifty put to protect a portfolio of midcaps or a single volatile stock leaves a basis gap, because they do not move together.

Regulation and Where to Verify the Numbers

The Indian derivatives market is regulated by SEBI, which sets contract rules, margin norms and expiry frameworks, while the RBI oversees currency derivatives used to hedge foreign exchange risk. These rules change. Lot sizes are revised periodically, STT rates have been increased in recent budgets, and expiry-day arrangements are updated from time to time. The illustrative numbers in this guide use a Nifty lot size of 65, but you must confirm the current figure before trading.

For authoritative, up-to-date specifications, check NSE India for lot sizes and expiry calendars, SEBI for regulations, and Zerodha Varsity for worked tutorials. Always confirm live premiums, charges and tax rules with your broker and a tax professional, because the right hedge is the one priced on today's real numbers, not yesterday's.
