What Is a Protective Put? Strategy, Cost, Risk and Example
Learn how a Protective Put works, how buying a put can protect an equity position, the cost of insurance, payoff mechanics and a practical example.
# What Is a Protective Put?
A Protective Put is an options hedging strategy in which an investor owns an underlying asset and buys a Put Option to protect against a significant decline.
It is similar to buying insurance.
The investor keeps upside exposure while the put provides downside protection below the selected strike, subject to the premium paid.
Basic Structure
A protective put consists of:
Long Stock or ETF + Buy Put Option
For example, suppose an investor owns an asset and buys a put with a strike below the current price.
Simple Stock Example
Suppose a stock is trading at ₹1,000.
An investor owns 100 shares and buys a ₹950 Put for ₹25 per share.
Cost of protection:
₹25 × 100 = ₹2,500
What Happens If the Stock Rises?
Suppose the stock rises to ₹1,100 at expiry.
Shares gain:
₹100 × 100 = ₹10,000
The put expires worthless.
Net simplified gain after the put premium:
₹10,000 − ₹2,500 = ₹7,500
The hedge therefore reduces the upside return by its cost.
What Happens If the Stock Falls?
Suppose the stock falls to ₹800.
Shares lose:
₹200 × 100 = ₹20,000
The ₹950 put has ₹150 intrinsic value:
₹150 × 100 = ₹15,000
The put offsets much of the stock loss.
The remaining simplified loss is:
₹20,000 − ₹15,000 + ₹2,500 premium
= ₹7,500
Protective Put as Insurance
The simplest framework is:
Underlying = Asset
Put = Insurance
The investor pays a premium to reduce downside risk.
A put can expire worthless while still having served its purpose as insurance.
Maximum Loss
For a simple stock-plus-put position held through expiry, a simplified worst-case loss is:
Maximum Loss ≈ Purchase Price − Put Strike + Put Premium
per share, assuming the underlying can fall to zero and the put is exercisable/settled according to its contract terms.
Example With NIFTY
Suppose NIFTY is at 24,500.
An investor has long NIFTY exposure and buys a hypothetical 24,000 Put for ₹120.
The put creates protection below 24,000.
If NIFTY falls sharply, the put gains value as NIFTY moves below the strike.
But the investor has paid ₹120 for that protection.
Protective Put vs Stop Loss
A stop loss and protective put are different tools.
Stop Loss: Attempts to exit the underlying after a trigger.
Protective Put: Keeps the underlying while the put provides option-based protection.
A gap-down move can cause a stop-loss execution at a worse price than expected.
An option hedge behaves differently because the put remains part of the position.
Protective Put vs Covered Call
A protective put is purchased for downside protection.
A covered call involves owning the underlying and selling a call for premium income.
| Feature | Protective Put | Covered Call |
|---|---|---|
| Underlying | Owned | Owned |
| Option | Buy Put | Sell Call |
| Main objective | Downside protection | Premium income |
| Upside | Retained, less premium cost | Capped above call strike |
| Premium | Paid | Received |
The two can also be combined into a collar.
Cost of Protection
The main disadvantage is recurring premium.
If protection is purchased every month, the premium can become a meaningful drag on long-term returns.

When Can It Make Sense?
An investor might consider a protective put when:
Frequently Asked Questions
Is a protective put free?
No. The investor pays the put premium.
Does it eliminate all losses?
No. Protection depends on strike, premium, expiry and position size.
What if the market never falls?
The put can expire worthless, making the premium a cost of insurance.
Can ETFs be hedged this way?
Conceptually yes, where a suitable liquid put option exists. The hedge may not perfectly match the ETF or portfolio exposure.
Final Thoughts
A protective put changes the objective from:
"I want maximum upside."
to:
"I want to stay invested, but I also want downside protection."
The trade-off is the premium.
Before using one, calculate the protection level, premium cost, expiry and position size.
