Beginner Strategies: Protective Puts (Hedging 101)
Protective puts are insurance for your stock. You buy a put while holding shares so that a sharp drop won’t derail your portfolio. You pay for protection, but it caps downside risk.
Before You Trade
These examples and charts are simplified teaching models. Confirm live pricing, liquidity, and assignment risk in your broker before placing real trades.
Protective Put Basics
How the hedge works
You own 100 shares and buy 1 put. The put gives you the right to sell your shares at the strike price. If the stock falls, the put gains value and offsets losses.
Protective put payoff: downside is limited below $95, but the premium reduces profits.

What You're Insuring
Protect the downside you can’t afford
Think of the put as disaster insurance. It’s most valuable when you want to stay invested but can’t tolerate a large drawdown (earnings risk, market events, or concentrated positions).
Insurance mindset
If you’d lose sleep over a 15–20% drop, a protective put can define your worst-case outcome while you keep long exposure.
Cost of Protection
Insurance isn’t free
The put premium reduces your stock gains. Longer-dated or closer-to-the-money puts cost more, but they provide stronger protection.
Longer protection windows cost more premium (illustrative).

Greeks In Action
Vega helps, theta hurts
Protective puts are long vega (they gain value if volatility rises) but they lose value from time decay. If volatility spikes during a selloff, the put can become more valuable even before price hits the strike.
Higher implied volatility increases the put’s value (vega effect).

Theta causes the protective put to bleed value as time passes.

When It’s Worth It
Use it strategically
Protective puts are most useful when downside risk is elevated and you need to stay invested. Think earnings season, macro events, or a concentrated holding you can’t afford to sell.
Worth it when…
- • You need short-term protection around known events.
- • Your portfolio is concentrated in one name.
- • You want to stay long but cap downside risk.
Maybe skip when…
- • You can reduce risk by trimming the stock instead.
- • Volatility is already extremely high and protection is expensive.
- • Your time horizon is long and you can ride out drawdowns.
Who This Is For
Stock owners who want to protect their holdings against a significant drop without selling their shares.
Learning Objectives
- • Explain how a protective put works as insurance for your stock position.
- • Calculate the cost of protection and its effect on your net returns.
- • Understand how vega and theta affect a protective put over time.
- • Decide when a protective put is worth the cost vs. other alternatives (selling shares, collars).
Risk Note
The main cost of a protective put is the premium, which reduces your net return if the stock goes up or stays flat. If the stock does not drop, you lose the premium—similar to paying for insurance you never use. Over time, repeatedly buying puts can significantly drag on performance.
Example Walkthrough
Scenario: You own 100 shares of XYZ at $100. You buy the $95 put expiring in 60 days for $2.50 ($250 total).
Best case: XYZ rises to $115
Stock gain: +$15/share. Put expires worthless: −$2.50/share. Net: +$1,250. You paid for insurance you did not need, but your profit is still strong.
Worst case: XYZ drops to $75
Stock loss: −$25/share. But the put is worth $20 ($95 − $75). Net loss: ($−25 + $20 − $2.50) × 100 = −$750. Without the put, you would have lost $2,500. The put saved you $1,750.
Breakeven: $100 + $2.50 = $102.50 (to recover the put cost, the stock must rise by the premium). Max loss: ($100 − $95 + $2.50) × 100 = $750.
Common Mistakes
Buying protection when IV is already high
When volatility spikes (like during a selloff), puts become expensive. Buying protection at peak fear means paying a premium for inflated IV.
Choosing too short an expiration
A 7-day put is cheap but decays fast. If the drop takes longer to materialize, the put can expire worthless before it helps.
Over-insuring routinely
Buying puts every month on all holdings drags heavily on returns. Use protective puts strategically around events, not as a permanent habit.
Quick Recap
- • A protective put = long 100 shares + long 1 put. It caps your downside at the strike minus the premium cost.
- • You pay the put premium as the cost of insurance; if the stock goes up, the premium is your only loss.
- • Best used strategically around specific events (earnings, macro risk) rather than as permanent protection.
