A protective put is a simple and effective way to add downside protection to an equity portfolio using options. In India, this strategy is available on many large-cap stocks and indices like Nifty and Bank Nifty through the derivatives segment. The idea is similar to buying insurance: you keep upside potential in your shares, but you limit losses if the market falls.
What a protective put does
A protective put means you own the underlying stock (or index exposure) and you buy a put option on the same underlying. If prices fall sharply, the put increases in value and offsets some or all of the loss on your holdings. If prices rise, you still benefit from the upside, only losing the premium you paid for the put.
When this makes sense
Use this when you are bullish to neutral for the long term but worried about near-term volatility or an upcoming event (earnings, budget, geopolitical news). It is particularly useful for concentrated positions or for investors who cannot afford a large drawdown.
Basic example in Indian terms
Suppose you hold shares worth Rs 5,00,000 of a listed company or an equivalent Nifty position. You buy a put with a strike at 90% of current price and an expiry one month out. If the put premium is 2% of your holding (about Rs 10,000), that premium is like paying an insurance fee. If the market falls 20%, your put gains and cushions most of the loss; if the market rises, you keep the gains minus the Rs 10,000 premium.
Step-by-step guide
Selecting strike and expiry in practice
- If you want almost full protection for a short threat (one upcoming report), choose near-the-money and short expiry. Expect to pay a higher premium.
- If you worry about a moderate drop over a quarter, choose a lower strike or longer expiry to balance cost.
- Many investors use a staggered approach: one or two different expiry strikes to smooth premium costs.
Cost considerations and tax
The main cost is the premium. In India, option premiums are subject to brokerage and transaction costs. Profit or loss from options is taxed as per trading or capital gains rules depending on how you classify your transactions; consult a chartered accountant for personal guidance. Remember to account for the premium as a real cost when comparing returns.
Advantages and trade-offs
Advantages: Limits downside, preserves upside, flexible for different time frames, useful for concentrated holdings.
Trade-offs: Premium reduces net return, protection lasts only until expiry, and frequent rollovers can add trading costs.
Alternatives and complements
- Collar strategy: Sell a call and buy a put to partially finance the put premium, but this limits upside.
- Stop-loss orders: Simpler, but can trigger on temporary dips and do not work for gaps at open.
- Diversification: Often the cheapest long-term protection is spreading risk across sectors and asset classes.
A practical tip
If premiums on a single stock option are very high due to illiquidity or wide spreads, consider hedging by using index options that track the broader market exposure. Always check lot sizes and margin requirements before placing orders.
Protective puts are a powerful tool to manage risk in Indian portfolios. When used deliberately—matching strike, expiry and cost to your risk tolerance—they offer a clear way to sleep easier during volatile periods while keeping the chance to benefit from market gains.

Step-by-step guide
- Decide what you want to protect: a single stock, a basket, or index exposure. Know the rupee amount you want to guard.
- Choose strike level: closer strikes (near-the-money) give stronger protection but cost more. For example, a 90% strike protects more than an 80% strike.
- Pick expiry: shorter expiries are cheaper but need frequent rollover. Longer expiries cost more but reduce the need to trade often.
- Buy the put: execute through your broker in the F&O segment. Keep in mind lot sizes for stock options; sometimes you might hedge using index options if single-stock lots are large.
- Monitor and decide: either let the put expire, exercise it if you want to sell, or sell the put before expiry to recover some premium.
