Derivatives have a reputation as instruments of speculation, but they were invented to do the opposite: to let someone who holds a risk pass it to someone willing to bear it. For an investor with a real portfolio, that original purpose is the useful one. Hedging is how you hold your stocks through a period you are genuinely worried about without selling everything and triggering tax and timing decisions you would rather not make.
A farmer who fears a bad monsoon does not burn the field — he buys crop insurance. In a good year the premium is a small cost he barely notices; in a bad year it saves him. He would never insure every field every year regardless, because the premiums would eat the farm.
A hedge is that crop insurance for a portfolio. Bought around a specific risk it is prudent; bought permanently it quietly consumes your returns. The judgement is when the storm is worth insuring against.
Size the hedge by beta, not by value
Three ways to do it, and what each costs
| Method | Protects downside | Keeps upside? | Cost |
|---|---|---|---|
| Short index futures | Yes | No — capped both ways | Low upfront; carry and basis |
| Buy index puts | Yes, below the strike | Yes | Premium, lost if no fall |
| Collar (put + short call) | Yes, below the put | Only up to the call strike | Cheap or free; upside given up |
When hedging is worth it, and when it is a slow leak
A hedge is a cost, and over the long run the market rises, so a permanently hedged portfolio systematically underperforms an unhedged one — it is paying insurance premiums on a house that mostly does not burn. That is why hedging pays off around specific, identifiable, time-bounded risks: a concentrated position through its results, a portfolio you cannot sell for tax reasons through an election or a budget, a known liquidity need in a nervous market. Bought for a reason and a period, a hedge is prudent. Bought as a permanent posture, it is a slow leak in your returns.
You hold a ₹15 lakh portfolio with a beta of 1.4 and want to hedge it with index futures before an uncertain event. What size hedge roughly neutralises it?
- Derivatives were built to transfer risk; hedging a real portfolio is their most defensible use.
- Size a hedge by the portfolio’s beta-adjusted index exposure, not by its plain rupee value.
- Short futures are cheap but cap upside; puts keep upside but cost premium; a collar trades upside for cheap protection.
- A hedge is a cost — worth it around specific, time-bounded risks, a slow leak if held permanently.
- Hedges are imperfect and can become bets; keep them smaller than, and opposite to, the holding they protect.

Common questions
Short, direct answers to what people ask about this topic.
- how do i hedge my stock portfolio
- The common ways are to short index futures against your holdings, or to buy index put options as insurance, so that a market fall produces a gain on the hedge that offsets the loss on the portfolio. The size of the hedge is scaled by your portfolio’s beta to the index, not just its rupee value. Each method has a cost — carry and basis for futures, premium for puts — which is the price of the protection.
- what is beta hedging
- Beta hedging sizes a hedge using the portfolio’s beta — its sensitivity to the index — rather than its plain value. A ₹10 lakh portfolio with a beta of 1.3 behaves like ₹13 lakh of index exposure, so it needs a hedge sized to ₹13 lakh to be neutralised, not ₹10 lakh. Ignoring beta leaves a high-beta portfolio under-hedged and a low-beta one over-hedged.
- is it better to hedge with futures or options
- Shorting index futures removes both downside and upside symmetrically and costs little upfront, but it caps your gains if the market rises. Buying index puts protects the downside while leaving the upside intact, but you pay a premium that is lost if the fall never comes. Futures are cheaper but two-sided; options preserve upside but cost a premium — the choice depends on whether you want to keep your upside.
- what is a collar in options
- A collar protects a holding by buying a put for downside protection and selling a call to fund it, giving up the upside above the call’s strike in return for cheaper or free protection below the put’s strike. It brackets your outcome between two prices. It suits an investor who wants to limit downside through a risky period and is willing to cap the upside to avoid paying much for it.
- does hedging reduce my returns
- Usually yes, over time, which is the point people miss — a hedge is a cost, like insurance, and a portfolio that is permanently hedged gives up much of the market’s long-run return to pay for protection it mostly does not need. Hedging earns its keep around specific, identifiable risks over defined periods, not as a permanent state. The skill is knowing when the protection is worth its cost.
