Introductory Context
"Individual stock option hedging is governed by the same principles as index option hedging (put protection, put spreads, collars) but with specific differences: Indian individual stock options are physically settled (not cash-settled like index options), have different lot sizes from Nifty, may have wider bid-ask spreads (lower liquidity than Nifty options), and are subject to the specific stock's earnings calendar and corporate event schedule that affects option IV independently of the broad market VIX. "
When Individual Stock Hedging Is Most Important
Three scenarios make individual stock options hedging most urgently appropriate: (1) Concentrated ESOP holdings where the stock cannot be sold immediately (lock-up periods, regulatory restrictions, tax optimisation strategies). The investor's net worth is heavily concentrated in a single company whose stock price can move independently of the market. (2) Inherited or legacy equity positions in a single company that represent a large fraction of the portfolio and where immediate selling would trigger large capital gains taxes. The investor wants to maintain the position for tax reasons but needs protection against a large decline. (3) Large single-stock bets where an investor has made a concentrated investment thesis and wants to protect the downside while awaiting the thesis to materialise.
Stock Option Hedge Construction
The construction is identical to the Nifty put hedge: select the put strike (protection level below the current stock price), select the expiry (protection window), calculate the number of lots (stock-specific calculation using the stock's own lot size). Example: HDFC Bank at Rs 1,750 per share. Concentrated position: 3,000 shares (Rs 52.5 lakh). HDFC Bank lot size: 550 shares. Lots held: 3,000 / 550 = 5.45 ≈ 5 lots (rounded for hedging purposes). Buy 5 lots of HDFC Bank 1,600 PE (8.6% OTM) at Rs 38 per unit. Cost: Rs 38 × 550 × 5 = Rs 1,04,500 per quarter. Protection: below Rs 1,600 per share, every additional point of decline is protected.
ESOP concentration hedge with collars: for ESOP holders who cannot sell the shares, the zero-cost collar (buy OTM put, sell OTM call) is the most commonly used structure. The call cap limits future appreciation above the call strike, but since the investor cannot sell the shares anyway (lock-up), surrendering some of the future gain is less costly than an uncapped hedging cost. The call premium offsets the put cost, creating the zero-cost structure without requiring any cash outlay from an investor who may have limited liquidity.
Physical Settlement Considerations for Indian Stock Options
Unlike Nifty options (which are cash-settled at expiry), Indian individual stock options are physically settled at expiry: if the put is exercised (the stock falls below the put strike at expiry), the put buyer must deliver the stock shares at the put strike price and receives the strike price in cash. For the hedger who actually owns the shares (the most common use case): physical settlement is desirable -- if the stock falls below the put strike and the put is exercised, the investor sells the shares at the protected strike price (receiving the strike price) and the hedge has functioned perfectly.
However: physical settlement creates a specific management requirement for the hedger who wants to maintain the stock position (not sell the shares through put exercise). In this case, the put must be closed (sold) before expiry if it is significantly ITM -- otherwise, automatic exercise at expiry would force the share sale. The hedger who wants to maintain the position: either close the ITM put before expiry and buy a new put for the next quarter (rolling the hedge), or exercise the put and simultaneously repurchase the shares in the market (maintaining the position while realising the hedge gain). The rolling approach is simpler and avoids the two-transaction cost of exercise + repurchase.
The single-stock options hedge is protection against the event that the Nifty hedge explicitly does not cover: the company-specific collapse that occurs in a bull market. When a company restates earnings, a key executive departs suddenly, a regulatory investigation is announced, or a major product recall occurs, the stock can fall 20 to 40 percent while Nifty is unchanged or rising. The investor with only Nifty puts loses the full company-specific decline unhedged. The investor with stock-specific puts is fully protected.
Individual Stock Option Liquidity Varies Significantly
Not all NSE-listed stock options are liquid enough for efficient hedging. Before implementing a single-stock option hedge: check the bid-ask spread for the specific put at the desired strike and expiry. If the bid-ask spread exceeds Rs 4 to Rs 5 per unit: the transaction cost of executing and rolling the hedge may be significant (Rs 4 x 550 lots x 5 contracts = Rs 11,000 per round-trip transaction). For stock options with wide bid-ask spreads, consider whether an index option hedge (using Nifty puts adjusted for the stock's beta) might be more cost-efficient despite its inability to cover idiosyncratic risk.
