Protective Put Spread: Cheaper, Partial Downside Insurance
You want downside protection but a full protective put's premium feels expensive. A protective put spread buys a put and sells a lower one against it, cutting the cost of the hedge in exchange for a floor that only protects down to the lower strike, not all the way to zero.
- Exactly what you own and hedge: stock protected by a put spread instead of a single put
- The payoff: cheaper hedge, protection that stops at the lower strike
- Your numbers: net cost of the hedge, the protected range, where protection ends
- When a protective put spread fits and the gap it leaves compared to a full protective put
A protective put spread takes a plain protective put and makes it cheaper by selling a lower put against it. You still buy the downside protection you want, but you fund part of the cost by giving up protection below a certain price. It is a budget-conscious hedge: cheaper than full insurance, but with a deductible that kicks in if the stock falls far enough.
What You Actually Do
You own 100 shares of Apple at $200. A full protective put might cost you $5 a share for a $190 strike. Instead, you buy that $190 put for $5 a share, $500, and sell a $170 put for $1.50 a share, $150.
Your net cost: $500 minus $150 = $350, compared to $500 for the full protective put, a meaningful savings. Your protection now runs from $190 down to $170: if Apple falls to $175, you are protected as if you owned a $190 floor. But below $170, the short put's losses offset your long put's gains, and you are exposed to further declines just like an unhedged stockholder.
The Payoff, Drawn
Drag the slider to see how you do at different ending prices for Apple (at expiration).
The shape protects you in a band, between $190 and $170, but re-exposes you below $170 as the short put's obligation grows alongside your long put's gain, netting out to the same slope as unhedged stock. Above $190, you participate fully in the stock's upside, reduced only by the smaller $350 hedge cost.
The Deductible: Cheaper Insurance, With a Gap
A protective put spread is insurance with a deductible built in on the far end.
A full protective put protects you all the way down to zero, no matter how far the stock falls, for the cost of one put's premium. A protective put spread cuts that premium by selling a lower put, but the price is a hole in your coverage: once the stock falls below your short put's strike, its losses cancel out your long put's gains, and you are back to full stock-like risk. The strategy assumes you want protection from a moderate drop but do not need (or cannot afford) protection from a true collapse.
The math: the wider you set the gap between your two strikes, the more premium you save, but the more exposure you leave open below the short strike. Setting the strikes too close together barely saves any money; setting them too far apart barely protects you.
When a Protective Put Spread Fits
- You want downside protection at a lower cost than a full put
- You are comfortable with protection stopping at a lower strike
- You expect a moderate drop, not a severe crash
- You fear a severe crash past the lower strike
- The premium savings are too small to justify the gap in coverage
- You would rather pay more for full protection to zero
A protective put spread is for the budget-conscious stockholder who wants meaningful downside protection without paying full price, and who believes a moderate decline is more likely than a severe crash. It is not for traders specifically worried about tail risk or a true market collapse.
A Worked Example
Walk through three scenarios: you paid $350 net for the put spread hedge.
Apple stays at $200. Both puts expire worthless. You lose the $350 hedge cost, same as any insurance you did not need to use.
Apple falls to $180. Inside your protected band (between $190 and $170). Your long put is $10 ITM, worth $1,000, offset by your short put still being worthless. Net protection kicks in fully, capping your loss near the $190 floor minus the hedge cost.
Apple crashes to $150. Below your short put's $170 strike. Your long put is $40 ITM ($4,000), but your short put is also $20 ITM, costing you $2,000. The two offset, leaving you exposed to the decline much like an unhedged stockholder, minus the net benefit already locked in between $190 and $170.
That is the protective put spread: real savings on your hedge cost, in exchange for a coverage gap on the most severe declines.
- A protective put spread is buying a put and selling a lower put against stock you own, cutting hedge cost.
- Protection is banded: full coverage between the two strikes, exposure returns below the lower strike.
- Cheaper than a full protective put, but with a real gap in coverage on severe declines.
- It fits budget-conscious stockholders expecting a moderate drop, not a full-blown crash.
Pop Quiz
Two quick checks. Pick an answer and the explanation shows up right away.
Why is a protective put spread cheaper than a plain protective put?
The short put's premium directly reduces the net cost of the hedge compared to buying the long put alone.
What happens to your protection if the stock falls below the short put's strike?
Below the short put's strike, both puts move deeper in the money together, and their gains and losses cancel out, leaving your net exposure similar to owning unhedged stock.
Bottom Line
A protective put spread trades full downside protection for a cheaper hedge, by selling a lower put against your long protective put. It fits stockholders who want meaningful protection from a moderate decline without paying the full premium a plain protective put demands. Reach for it when you expect the risk of a moderate pullback but not a true crash. Avoid it if a severe decline past your lower strike is exactly the scenario you are most worried about.
