Protective Put

What is a Protective Put?

A protective put is when you own shares of a stock and buy a put option to protect them from a drop. It works like an insurance policy. If the stock crashes, your put gains in value and offsets the losses on your shares. If the stock goes up, you keep all the upside minus the small cost of the put.

This is the go-to hedging strategy for investors who are long-term bullish on a stock but worried about a short-term pullback. You pay a premium for peace of mind.

How to Set It Up

• Own 100 shares of the underlying stock
• Buy 1 put option at a strike price below the current stock price
• Strike selection: Choose based on how much downside you want to protect against. A put at 5% below current price costs more but protects more. A put at 10% below is cheaper but gives you less protection.
• Expiration: Match it to how long you need protection. If you are worried about earnings next month, buy a 30-day put. If you want protection for a quarter, go 90 days.

The put costs money. That premium is the price of your insurance.

When to Use This Strategy

Use a protective put when:

• You own shares with significant unrealized gains and want to lock in profits
• An earnings report, Fed meeting, or macro event is coming and you are nervous
• The market looks fragile but you do not want to sell your shares (maybe for tax reasons or because you are still long-term bullish)
• You have a concentrated stock position and need defined risk

This is not a strategy you run all the time. If you bought puts every month on every stock you own, the cost would eat into your returns significantly. Use it selectively when the risk warrants it.

Example Trade

You own 100 shares of XYZ at $100 per share. Earnings are next week and you are nervous.

• Buy 1 XYZ $95 put expiring in 30 days for $2.00
• Cost of protection: $2.00 x 100 = $200
• Floor: Your shares cannot lose more than $5 per share (from $100 to $95 strike), plus the $200 put cost

Scenario 1: XYZ drops to $80. Without the put, you lose $2,000. With the put, your shares lose $2,000 but your put is worth $15. Net loss = $2,000 - $1,500 + $200 cost = $700. The put saved you $1,300.

Scenario 2: XYZ goes to $115. Your shares are worth $11,500. The put expires worthless. Total gain = $1,500 minus the $200 put cost = $1,300. The insurance cost you $200, but you kept all the upside.

Scenario 3: XYZ stays at $100. The put expires worthless. You are down $200 (the cost of the put). That is the insurance premium you paid for peace of mind.

Risk and Reward

• Max profit: Unlimited. Your shares can go as high as they want. The only drag is the premium you paid for the put.
• Max loss: Defined. The worst case is the stock drops below your put strike. Your loss is (stock cost - put strike + premium paid) x 100. In our example, ($100 - $95 + $2) x 100 = $700.
• Breakeven: Your stock cost plus the put premium. $100 + $2 = $102. The stock needs to be above $102 at expiration for you to be net positive.

Tips and Common Mistakes

• Do not buy too far OTM. A really cheap put at $80 when the stock is at $100 barely protects anything. You need the stock to crash 20% before the put even kicks in.
• Use it selectively. Protective puts are for specific high-risk periods, not a permanent portfolio hedge. The cost adds up.
• Consider a collar instead. If the put premium is too expensive, you can sell a covered call to offset the cost. That is a collar strategy and it makes the protection nearly free.
• Do not confuse this with a long put. A protective put is about hedging shares you own. A long put is a standalone bearish bet.

Related Strategies

• Collar — adds a covered call to reduce or eliminate the cost of the protective put
• Long Put — a standalone bearish trade, not a hedge
• Covered Call — generates income on your shares, but does not protect the downside
