Protective put (also called married put) is a hedging strategy where you own shares and buy put options as insurance against a price decline. The put option increases in value if the stock falls, offsetting your stock losses. Unlike covered calls which generate income, protective puts cost money but preserve unlimited upside while limiting downside risk.
- Own 100 shares + buy 1 put option
- Insurance against downside
- Keeps unlimited upside (minus premium cost)
How Protective Puts Work
Protective puts act as portfolio insurance:
Protective Put Example:
Own: 100 shares at $100 ($10,000 position)
Buy: 1 $95 Put expiring in 60 days
Premium Paid: $3.00 per share ($300)
Scenarios at Expiration:
Stock at $80 (crash):
Stock loss: $2,000
Put value: $15 × 100 = $1,500
Net loss: $2,000 - $1,500 + $300 = $800
(vs $2,000 loss without put)
Stock at $100 (unchanged):
Stock: No gain/loss
Put expires worthless
Total loss: $300 (premium paid)
Stock at $120 (rally):
Stock gain: $2,000
Put expires worthless
Net gain: $2,000 - $300 = $1,700
Quick Reference: Protective Put Outcomes
| Stock Move | Stock P/L | Put Value | Net P/L |
|---|---|---|---|
| Falls hard | Large loss | Large gain | Limited loss |
| Flat | None | Worthless | -Premium |
| Rises | Gain | Worthless | Gain - Premium |
Example: Earnings Protection
Protecting Position Before Earnings:
| Factor | Value |
|---|---|
| Stock Position | 100 shares at $100 |
| Put Strike | $95 (5% OTM) |
| Put Premium | $4.00 |
| Protection Level | $95 per share |
| Cost of Protection | 4% of position |
| Max Loss | $5 + $4 = $900 (9%) |
Protective puts buy insurance for your stock position. Own shares and buy puts to limit downside. If stock crashes, put profits offset losses. If stock rises, put expires but you keep the gains minus premium paid. It’s insurance—costs money but provides peace of mind.

When to Use Protective Puts
Good Conditions
- Before earnings or major events
- Large concentrated position
- Paper gains you want to protect
- Uncertain but want to stay invested
- Near retirement or need the money
Avoid When
- Small positions (cost too high relative)
- Long time horizon (volatility normal)
- Very bullish (wasting money on insurance)
Cost-Effective Protection
Collars
Sell call to offset put cost. Caps upside but reduces net cost.
Put Spreads
Buy put, sell lower put. Cheaper but protection is capped.
Timing
Buy protection when IV is low. Expensive to protect during panics.
Common Mistakes
-
Buying too late – Protection expensive after stock already falling.
-
Too much protection – 10% annual drag kills returns over time.
-
Wrong strike – Too far OTM doesn’t help until major crash.
-
Forgetting it’s insurance – Expect to “lose” the premium most times.
