How to Hedge Your Portfolio Before Budget Day Using Options
To hedge a portfolio before Budget Day, size a Nifty put or put spread to cover 50 to 80 percent of your equity exposure, enter 2 to 4 days before, and exit within a day after.
You hold equity worth a few lakh rupees. Budget Day is a week away, and the market has a habit of moving 3 to 5 percent on the speech. You do not want to sell. You just want to insure the portfolio for 10 days. That is exactly what options are built for, and what hedging/hedging-stock-market">hedging in the stock market really means in practice.
A pre-Budget hedge is one of the simplest uses of options. You pay a small premium to cap downside and keep upside. The goal is not to make money on Budget Day — it is to sleep through it. Here are the steps, in order, with the common mistakes flagged.
Step 1 — Count your real equity exposure
Before you hedge, measure what you are hedging. Add up the current market value of all equity holdings — smallcase-and-thematic-investing/smallcase-industry-growth-india">direct stocks, 80c/rushing-march-80c-plan-better">elss-vs-flexi-cap-first-equity-savings-schemes/scss-maximum-investment-limit">investment">equity mutual funds, ETFs, and any long futures positions. This total is your exposure. Do not hedge individual stocks separately unless you hold highly concentrated names. For a market shocks historical examples">diversified portfolio, hedge at the index level.
Step 2 — Pick the right index to hedge against
Match the index to your portfolio's character. If your holdings are mostly large-cap Indian stocks and mutual funds, hedge with Nifty 50 options. If you hold mostly banking names, hedge with Bank Nifty. For a multi-cap portfolio, Nifty 50 is usually a good enough proxy — the correlation is high.
Mid-cap heavy portfolios are harder to hedge. Nifty Midcap Select options exist but have lower nse-and-bse/price-discovery-differ-nse-bse">liquidity. Stick to Nifty 50 unless your portfolio is clearly outside large-cap names.
Step 3 — Calculate the hedge size
The hedge size formula is simple: portfolio value divided by Nifty spot value times mcx-and-commodity-trading/lot-size-mcx-commodity-trading-matter">lot size. For example, if your equity portfolio is worth 10 lakh rupees and Nifty is at 22,000, the notional of one Nifty lot (lot size 25) is 22,000 multiplied by 25, which is 5.5 lakh rupees. So one lot covers 55 percent of your portfolio. Two lots cover 110 percent, which is over-hedged.
For a 10 lakh rupee portfolio, one Nifty put lot is usually the right size. Partial hedging is fine — hedging 55 percent costs less and still cushions most of the downside.
Step 4 — Choose the expiry and strike
Pick the weekly expiry that is 1 or 2 trading days after Budget Day. The day-of expiry is too short — premium decays fast and you may get whipsawed. An expiry 4 to 6 trading days post-Budget gives the hedge time to work if volatility persists.
Strike selection is the art. Three standard choices:
- ATM put — most expensive, tracks the portfolio 1-for-1 below the strike. Use when you are truly worried.
- 3 percent OTM put — half the premium of ATM, only kicks in if Nifty drops over 3 percent. Balanced choice.
- 5 percent OTM put — cheapest, only covers a sharp crash. Use if you expect a mild reaction but want tail protection.
Step 5 — Consider a put spread to cut cost
Pure put buying can be expensive, especially during the pre-Budget week when delta">implied volatility is high. A bear put spread reduces the cost: buy a 3 percent OTM put and sell a 6 percent OTM put. You cap the maximum protection at the spread width, but the net premium drops 30 to 50 percent.

Step 6 — Place the order and keep the margin ready
Buying a put requires the full premium in cash, which is around 0.5 to 1.5 percent of the protected notional depending on strike. Selling a put inside a spread requires margin. Your broker's margin calculator will show the net margin after the spread is set up. Ensure this sits in your demat-and-trading-accounts/essential-documents-nri-demat-account-opening">trading account before you place the order — a pre-Budget margin shortfall is the worst time to be funding an account.
Step 7 — Exit after Budget Day, do not hold to expiry
Most of the volatility premium drains out of options within 24 to 48 hours of Budget Day. Close the hedge the day after, even if you do not use it. Holding to expiry wastes whatever premium is left and ties up margin. If the market crashed, the put has gained and you exit profitably. If the market rallied, the put is worth very little — still close it and let the long portfolio run.
Common mistakes traders make
Three traps keep repeating on Budget hedges:
- currency-and-forex-derivatives/currency-hedge-gain-more-than-underlying">Over-hedging — buying 2 or 3 times the needed lots in fear. Pay too much premium, cap upside unnecessarily.
- Hedging too early — entering the hedge 2 weeks before Budget. Implied volatility spikes slowly, so early hedges bleed theta during the wait.
- Going too far OTM — buying a put 8 percent below spot. It protects against a crash that rarely happens, and you pay premium for nothing most of the time.
Tips that make the hedge work better
Keep these rules in mind for any event-based hedge, Budget or otherwise:
- Enter the hedge 2 to 4 trading days before the event, not earlier
- Exit within 1 trading day after the event, regardless of outcome
- Pair your put with a put spread to cut cost in half
- Size the hedge at 50 to 80 percent of the portfolio, not 100 percent
- Write down your exit plan before you place the order — hedges without exit plans become directional bets
A quick wrap-up
A pre-Budget hedge should cost 0.5 to 1.2 percent of the protected portfolio value for a week of insurance. That is a small price to lock out sharp downside during a known event. The National Stock Exchange publishes real-time gamma-sensibull-options-dashboard">option chain data so you can model the trade before placing it. Treat hedging as a tool for specific events, not a permanent overlay. Used well, it keeps your long-term portfolio intact while removing the fear of a single bad news day.
Frequently Asked Questions
- How much does it cost to hedge a portfolio for Budget Day?
- Usually 0.5 to 1.2 percent of the protected portfolio value for a week, depending on strike choice and volatility. A put spread cuts this to roughly 0.3 to 0.6 percent.
- Do I need derivatives approval from my broker to hedge?
- Yes. Your trading account must be F&O enabled. Most brokers activate it within a day after you complete the derivatives declaration and income proof.
- Is hedging every event worth it?
- No. Hedge only high-volatility known events like Budget Day, major RBI policy, or US Fed announcements. Hedging constantly eats returns through premium.
- Can I hedge with index futures instead of options?
- Yes, but shorting futures caps your upside. Puts protect downside and keep upside intact, which is why options are the preferred hedge for most equity investors.
