That tradeoff is really the whole story with futures hedging, and it's worth understanding properly before you use it, not after a margin call catches you off guard. Here's how it actually works, with real strategies and numbers behind them.
What does hedging with futures actually mean?
A futures contract is an agreement to buy or sell something, a stock, an index, a commodity, at a set price on a set future date. Hedging with futures means using that locked-in price to offset risk sitting somewhere else in your portfolio, so a bad move in one place gets balanced out by a favorable move in the other.
The key difference from options, and it's a big one, is obligation versus right. An option gives you the right to do something, and you can just let it expire if you don't need it, losing only the premium. A futures contract is a commitment. You're in it until you close the position or it expires, which changes the risk profile in ways worth understanding before you jump in.
How does a futures hedge actually work?
Say you're holding a diversified equity portfolio worth roughly ₹20 lakh, and you're nervous about a broad market drop over the next month, maybe there's a big macro event coming up. Rather than selling everything and buying it back later, you could sell Nifty futures worth roughly that same amount.
If the market falls, your portfolio loses value, sure, but your short futures position gains value at roughly the same pace, since you locked in a sell price now that's higher than where the market ends up. The losses on one side get offset by gains on the other. If the market rises instead, you lose on the futures position, but your portfolio gains, and you end up roughly where you started either way, protected from the downside but also giving up the upside during that window.
That's a short hedge, selling futures to protect something you already own. There's also a long hedge, which works the other way. Say you know you'll need to buy a large quantity of a stock, or a commodity, in a few months, and you're worried the price will climb before then. Buying futures now locks in today's price, protecting you from paying more later, even though you haven't actually made the purchase yet.
Common futures hedging strategies
- Portfolio hedge with index futures: This is probably the most common one for anyone holding a broad, diversified equity portfolio. Rather than hedging every individual stock, which would be a logistical mess, you short an index future, Nifty or Bank Nifty, roughly matched to your portfolio's value, protecting against broad market moves in one shot.
- Stock-specific futures hedge: Less common for smaller retail portfolios, mostly because stock futures come in fixed lot sizes that rarely line up neatly with what you're actually holding, but for a large concentrated position, shorting futures on
- Cross hedging: Sometimes there's no futures contract that matches exactly what you're trying to protect, so you hedge using something correlated instead, say, using a sector index future to hedge a stock in that sector when no direct futures contract exists for the stock itself. It's not a perfect match, there's real basis risk here since the two won't move in exact lockstep, but it's often better than no protection at all.
- Rolling the hedge: Futures contracts expire, unlike a position you can just hold indefinitely, so a hedge you want to maintain past expiry needs rolling into the next contract. Miss this, and your protection quietly disappears the moment the old contract expires, whether or not you meant for that to happen.
- Futures hedge vs options hedge, the quick version: The core tradeoff comes down to cost structure and obligation. Options cost you a premium upfront, and that's your maximum loss on the hedge itself, nothing more, ever. Futures don't cost a premium the same way, but they require margin, and they're marked to market daily, meaning gains and losses get settled in cash every single day the position's open, which can mean real cash flow demands if the trade moves against you.
Options give you the right to walk away. Futures are an obligation you're committed to until you close it out. Neither structure is better across the board, they just suit different situations and different comfort levels with ongoing cash requirements.
What does a futures hedge actually cost?
No premium, which sounds appealing, but don't mistake that for free. You need margin to open the position, typically a combination of SPAN margin and exposure margin set by the exchange, and that capital sits tied up for as long as the hedge is open, unavailable for anything else.
Then there's the daily mark-to-market settlement. If the hedge moves against you on any given day, meaning the market moved in the direction that hurts your futures position, you need to fund that loss in cash immediately, not wait until you close the position. This is genuinely one of the most underappreciated parts of futures hedging. The hedge might be working exactly as intended, offsetting your portfolio loss overall, but you can still face real, immediate cash demands along the way.
Common mistakes with futures hedging
- Forgetting to roll the hedge before expiry, and suddenly realizing your protection quietly vanished a week ago without you noticing. Set a reminder well before expiry, don't leave it to the last day.
- Ignoring the lot size mismatch. Futures come in fixed contract sizes, so your hedge will rarely match your actual exposure exactly, you're either slightly over-hedged or slightly under-hedged, and pretending otherwise leads to a false sense of precision that isn't really there.
- Not planning for margin calls. If you don't have cash set aside to meet daily mark-to-market demands, a futures hedge can force you into an awkward spot even while it's technically doing its job protecting your overall portfolio.
- Reaching for a futures hedge when a simple exit or a plain stop-loss would've done the job more simply. Futures hedging makes sense for specific situations, a portfolio you want to stay invested in through a rough patch, not as a default response to every bit of market nervousness.
