Protective Put vs Collar: Which Hedge Fits Your Stock Position?
A protective put and a collar are both ways to hedge a stock position you already own, and both start with the same building block: a long put purchased against your shares. The difference is what you do next. A protective put stops there, keeping your full upside in exchange for paying the put premium out of pocket. A collar adds a short call against the same stock, using the premium collected to reduce or eliminate the cost of the put, in exchange for capping how much you can make if the stock rallies.
This guide compares both strategies side by side, walks through a worked example using the same stock and put strike for each, and links to the free calculators so you can model your own numbers before placing a trade. Options trading involves risk, including the possible loss of the full amount invested.

What Is a Protective Put?
A protective put, sometimes called a married put, pairs 100 shares of stock you already own with one long put option on the same stock. The put acts as insurance: if the stock falls below the strike, the put gains value dollar for dollar with the decline, putting a floor under your loss. If the stock rises instead, you keep the entire gain, minus what you paid for the put. Max loss is the stock’s purchase price minus the put strike, plus the premium paid, multiplied by 100 shares. Breakeven is the purchase price plus the premium.
Because the put is the only extra leg, upside stays uncapped. The trade-off is cost: buying puts repeatedly to maintain continuous protection can drag a flat or slow-moving stock into a loss over time. Use the protective put calculator to see the exact floor and cost basis for your own strike and premium.
What Is a Collar?
A collar starts from the same protective put and adds a second leg: sell an out-of-the-money call against the same 100 shares. The premium collected from the call offsets some, all, or occasionally more than all of what the put costs. In exchange, the shares can be called away at the short strike, which caps how much of the stock’s rally you get to keep. Max profit is the call strike minus the stock’s purchase price, adjusted for the net premium; max loss is the purchase price minus the put strike, adjusted for the net premium; breakeven is the purchase price shifted by that same net premium.
A collar entered for a net credit (call premium collected exceeds put premium paid) lowers the breakeven below the stock’s purchase price and reduces the maximum loss. Some traders size the strikes so the two premiums roughly cancel out, known as a zero-cost collar. Use the collar options calculator to model your own strikes and see where the net premium lands.
Protective Put vs Collar: Key Differences
| Factor | Protective Put | Collar |
|---|---|---|
| Legs | Stock + long put | Stock + long put + short call |
| Hedge cost | Full put premium, paid out of pocket | Reduced, offset, or eliminated by the call premium |
| Upside | Unlimited, minus the premium paid | Capped at the short call strike |
| Max loss | Purchase price minus put strike, plus premium | Purchase price minus put strike, adjusted for net premium (often lower) |
| Breakeven | Purchase price plus premium | Purchase price adjusted for net premium |
| Fits when | Want to keep all of the stock’s upside | Want cheaper, or free, downside protection and can accept a cap |
The core trade-off is this: a protective put keeps every dollar of upside above the cost of the put, but that protection costs money every time you buy it. A collar largely or fully pays for that same downside floor by selling away the stock’s gains above the call strike. Neither strategy is strictly better; the right one depends on whether you would rather keep uncapped upside or keep the hedge as cheap as possible.
When to Use a Protective Put
A protective put tends to fit when you still expect meaningful upside from the stock and do not want to give any of it away. This is common heading into a catalyst you view as more likely to help than hurt, such as an earnings report on a stock you are bullish on, where you want downside insurance but do not want a call sold against you if the report goes well.
It also fits shorter hedging windows, where the cost of the put is a known, one-time expense rather than a recurring drag. The main risk is cost: if the stock does not fall, the premium paid for the put is a straightforward reduction to your return, with no offsetting credit to soften it.
When to Use a Collar
A collar tends to fit when protecting the position matters more than participating in a large rally, or when you plan to hold the hedge for an extended period and want to avoid the cost of repeatedly buying puts outright. Selling the call to finance the put is what makes continuous or long-duration protection practical for many stock holders.
Collars are also a common choice for concentrated stock positions, including employer stock or a position with a large unrealized gain, where the goal is limiting downside risk without selling the shares outright and triggering a taxable event. The limitation is the cap: if the stock rallies well past the short call strike, a collar holder gives up gains that a protective put holder would have kept in full.
A Quick Example with Real Numbers
Assume XYZ is trading at $100 and you own 100 shares. To keep the comparison direct, both examples use the same $95 put.
Protective put: Buy the $95 put for $2.50. Cost basis is $102.50 per share and breakeven is $102.50. Max loss is $750 (($100 − $95 + $2.50) × 100). Upside stays uncapped: if the stock rises to $120, the position gains $1,750 (($120 − $102.50) × 100).
Collar: Keep the same $95 put, and sell a $105 call for $2.50 against it. The two premiums offset exactly, for a net premium of $0, a zero-cost collar. Max loss is $500 (($100 − $95) × 100), a smaller loss than the naked protective put because the call financed the hedge. Max profit is capped at $500 (($105 − $100) × 100), reached once the stock is at or above $105 at expiration, regardless of how much further it rallies. Breakeven is $100, the stock’s purchase price, since the net premium is zero.
Same stock, same put, same strike. The collar costs less and loses less if the stock falls, but at $120 the protective put is worth $1,750 while the collar is capped at $500. The decision comes down to whether that extra $1,250 of potential upside is worth paying for out of pocket.
