Introductory Context
"For most practical hedging scenarios, the put spread's maximum payoff cap (limited protection below the lower strike) is not a significant disadvantage -- it only affects scenarios of extreme, prolonged declines. A Rs 5 lakh to Rs 8 lakh of protection on a Rs 50 lakh portfolio (from a 500 to 800-point Nifty spread) is meaningful for most typical bear markets, and the cost reduction from selling the lower put makes the hedge economically viable where a full protective put might be too expensive. "
Put Spread Hedge Construction
Example: Portfolio Rs 50 lakh (Nifty 23,500, beta 1.0, 3 lots). Standard protective put: buy 22,000 PE (6.4% OTM) at Rs 110. Cost: Rs 24,750 for 3 lots. Put spread hedge: buy 22,000 PE at Rs 110 AND sell 20,500 PE (12.8% OTM) at Rs 42. Net put spread cost: Rs 110 - Rs 42 = Rs 68 per unit. Total spread cost: Rs 68 x 75 x 3 = Rs 15,300. Cost reduction vs single put: Rs 24,750 - Rs 15,300 = Rs 9,450 saved per quarter (38 percent cost reduction). Maximum spread payoff per lot: (22,000 - 20,500) x 75 = Rs 1,500 x 75 = Rs 1,12,500 per lot. Total maximum spread gain: Rs 1,12,500 x 3 = Rs 3,37,500.
Protection profile of the put spread hedge: Nifty above 22,000: no hedge payoff. The portfolio's loss is unhedged above this level. Nifty 22,000 to 20,500: the hedge pays the difference between 22,000 and current Nifty level -- increasing protection as Nifty falls. At Nifty 21,000: hedge pays (22,000 - 21,000) x 75 x 3 = Rs 2,25,000. At Nifty 20,500: maximum hedge payoff = Rs 3,37,500. Nifty below 20,500: no additional hedge payoff (the sold 20,500 PE prevents further gains below this level). The portfolio's losses beyond the 20,500 level are unhedged.
Put Spread vs Single Put Hedge Comparison
Single put (22,000 PE): cost Rs 24,750/quarter. Protection: full below 22,000 to zero. Maximum payoff: unlimited (theoretically). Put spread (22,000/20,500): cost Rs 15,300/quarter. Protection: only for Nifty 22,000 to 20,500. Maximum payoff: Rs 3,37,500 (Rs 1,500 spread x 75 x 3). Cost saving: Rs 9,450/quarter. Protection gap: below 20,500, portfolio is unhedged again. Annual cost: Rs 61,200 (1.22% of portfolio). Protection: Rs 3,37,500 maximum (Rs 50L x 6.75% effective protection ceiling).
When the Put Spread Hedge Is Most Appropriate
The put spread is most appropriate for bear market scenarios where the expected maximum decline is within the spread's protection range. For Indian markets: a typical significant bear market (not a catastrophic crash) produces Nifty declines of 15 to 25 percent. For a portfolio of Rs 50 lakh: a 20 percent decline = Rs 10 lakh loss. A put spread providing Rs 3.37 lakh of maximum protection covers approximately 33.7 percent of this loss. A wider spread (say 22,000 to 19,500 = 2,500-point spread) would provide proportionally more coverage: maximum payoff = 2,500 x 75 x 3 = Rs 5,62,500 (56.25 percent of the typical bear market loss). The 2,500-point spread would cost more than the 1,500-point spread but less than the single put -- falling in the middle of the cost-versus-protection spectrum.
The put spread is less appropriate for catastrophic crash protection (2008-style 60 percent decline) because the sold lower put limits the hedge's payoff beyond the lower strike. For tail risk (black swan) protection: the single deep-OTM put from Topic 19.7 is more appropriate than the put spread, as it provides payoff all the way down from the strike to zero.
The put spread hedge is the options market's equivalent of a deductible-plus-coverage-cap insurance policy: there is an unprotected zone above the upper strike (the deductible), a protected zone between the two strikes (the coverage), and another unprotected zone below the lower strike (the coverage cap). Most bear markets land in the covered zone -- the 15 to 25 percent typical decline that a well-structured put spread captures efficiently. Catastrophic crashes that go beyond the lower strike are the rare events where the put spread's cap is actually reached -- and where the tail risk hedge from Topic 19.7 provides supplemental protection.
Layer Put Spreads and Tail Risk Puts for Comprehensive Cost-Efficient Protection
A comprehensive, cost-efficient hedge combines two layers: (1) A put spread (22,000/20,500 PE for Nifty at 23,500) providing 6.4 to 12.8 percent decline protection at moderate cost. (2) A deep OTM put (18,000 PE) providing tail-risk protection for declines beyond 23.4 percent at very low cost (approximately Rs 18 to Rs 22 per unit). The combined two-layer hedge costs Rs 68 + Rs 20 = Rs 88 per unit (total Rs 19,800 for 3 lots/quarter) versus Rs 110 for the single put -- a 20% cost saving while providing: partial protection 6.4-12.8%, full tail-risk protection below 23.4%. This layered structure is the most cost-efficient comprehensive hedge for most portfolios.
