Protective Put Strategy
Insurance for your shares — protect your stocks from a crash.
What is the Protective Put Options Strategy?
You have worked hard to build a stock portfolio. But markets can crash suddenly and wipe out months of gains. A Protective Put is like buying insurance for your shares.
You simply buy a put option on shares you already own. If the stock falls sharply, your put option profits and covers most of the loss. If the stock rises, you fully participate in the upside — you only "lose" the small insurance premium you paid.
This is one of the most practical strategies for long-term investors who want to keep their stocks but sleep better at night during uncertain times.
Why is it Called "Protective Put"?
"Protective" says exactly what it does — it protects. "Put" is the option contract. Together: a put option that protects your shares. Some traders call this "married put" because you pair (marry) the put directly to the shares you own.
How Does the Protective Put Trade Work?
- 1 Step 1 — Already own at least 100 shares of a stock you want to protect.
- 2 Step 2 — Buy one put option on that stock, with a strike at or below the current price.
- 3 Step 3 — Pay the premium. Think of this as your insurance premium.
- 4 Step 4a — If the stock rises: put expires worthless, you keep all share gains.
- 5 Step 4b — If the stock crashes: your put gains in value and offsets the loss on your shares.
Types of Protective Put Strategies
Protective Put (Direct Insurance)
Buy one put for every 100 shares you own. Closest to traditional insurance. Gives you the right to sell your shares at the strike price no matter how far they fall.
Portfolio Hedge (Index Puts)
Instead of buying puts on individual stocks, buy puts on a broad index (like NIFTY or SPY) to protect your whole portfolio at once. Cheaper and simpler than protecting each stock individually.
When to Use the Protective Put Strategy?
- When you own stocks you love long-term but are worried about a short-term crash
- Before a period of high uncertainty — election season, earnings, geopolitical tension
- When you have large unrealised gains you want to lock in and protect
- When option prices are still cheap (before fear spikes)
Profit and Loss of the Protective Put
Before looking at the chart, here is a plain-English summary of what you can make and what you can lose.
Unlimited — your shares can still rise as much as they want. The put does not limit upside at all.
Limited to the premium you paid for the put, plus any fall in the stock from the current price down to the strike.
Current share price + premium paid for the put.
Protective Put Payoff Diagram
The chart below shows how profit/loss changes with the underlying price at expiry. Green zone = profit, red zone = loss.
Protective Put Example Trade
| Action | Type | Strike | Premium |
|---|---|---|---|
| Own | Stock | 100 shares @ ₹3,800 | ₹3,80,000 value |
| Buy | Put | ₹3,600 | -₹45 per share |
TCS falls sharply from ₹3,800 to ₹3,400 after a bad quarter. Your shares lost ₹40,000. But your put is now worth ₹200 per share = ₹20,000. Net loss = only ₹24,500 instead of ₹40,000. The insurance saved ₹15,500.
Pros & Cons of the Protective Put
- Keeps all the upside of your shares — protection does not limit gains
- Sets a clear floor on your losses — you always know your worst case
- Peace of mind during volatile periods without having to sell your shares
- Can protect your portfolio through uncertain events without exiting positions
- Costs money every time you renew — like paying insurance premiums monthly
- If the stock never falls, you lose the premium — just like insurance you never use
- Requires buying new puts every month or quarter to maintain protection
- Does not protect against a gradual slow decline over many months
