What Is a Collar in Options Trading?

A collar is an options strategy that combines stock ownership, a protective put, and a covered call to limit downside risk while also capping upside.

What Is a Collar in Options Trading?

A collar is an options strategy used by investors who already own a stock and want to limit downside risk for a period of time without giving up the position entirely.

The basic idea is straightforward: you keep your shares, buy a put option for downside protection, and sell a call option to help offset the cost of that protection.

That tradeoff is the heart of the strategy. The put can help reduce losses if the stock falls, but the call caps how much you can profit if the stock rises strongly. In plain English, a collar is a way to give up some upside in exchange for more protection on the downside.

It can be thought of as a more protective cousin of the covered call and a stock-based alternative to a married put.

What Is a Collar?

A collar is created when an investor owns 100 shares of a stock, buys 1 put option, and sells 1 call option on the same stock.

The put acts as protection below a chosen price. The short call helps pay for that protection, but it also creates an obligation to sell the shares at the call strike price if the stock rises enough.

Because of that structure, a collar places the stock position inside a range. The put helps set a floor, and the short call helps set a ceiling.

How a Collar Is Built

  • Own 100 shares of a stock

  • Buy 1 put option below the current stock price

  • Sell 1 call option above the current stock price

  • Use the same expiration date for both options in many standard examples

The long put is there for protection. The short call brings in premium, which can reduce or sometimes nearly offset the put cost depending on pricing.

This is why some investors think of a collar as a more budget-conscious hedge than buying a protective put by itself.

When Traders Use a Collar

A collar is usually used when an investor is still willing to hold a stock but wants to reduce near-term downside risk.

This can happen when:

  • the stock has already gone up and the investor wants to protect some gains

  • the investor is nervous about a short-term drop but does not want to sell the shares

  • the investor wants a clearer risk range for a period of time

  • the cost of a protective put alone feels too expensive

The strategy is often described as a hedging strategy rather than a pure speculation strategy. The main goal is usually risk control, not maximizing upside.

How a Collar Makes or Loses Money

A collar changes the normal stock payoff in two ways.

First, the put can help limit losses if the stock falls below the put strike. Second, the call limits upside if the stock rises above the call strike.

That means the position usually has:

  • limited downside compared with owning stock alone

  • limited upside compared with owning stock alone

  • a result that depends partly on the net cost or net credit from the options

The exact maximum profit and maximum loss depend on the stock entry price, the put strike, the call strike, and the net premium paid or received when the collar is opened.

In general:

  • the worst losses are reduced because the put helps protect the stock below a certain level

  • the best gains are capped because the call can require the shares to be sold at the strike price

A Simple Collar Example

Imagine you own 100 shares of a stock at $50 per share.

You decide to build a collar like this:

  • buy 1 $45 put for $2.00

  • sell 1 $55 call for $1.00

The net option cost is $1.00 per share, or $100 total.

Here is what that means in simple terms:

  • If the stock rises above $55: your upside is capped around that level because the short call can be exercised.

  • If the stock stays between $45 and $55: both options may expire with little or no value, and your result mainly comes from the stock move plus the net option cost.

  • If the stock falls below $45: the put becomes more valuable and helps limit additional losses.

You still face risk, but not the full downside of an unhedged stock position. The tradeoff is that you no longer get unlimited upside while the collar is in place.

Main Risks and Tradeoffs

  • Upside is capped. If the stock rallies strongly, you may have to sell your shares at the call strike price and miss further gains.

  • Protection is not free. Even if the call helps offset the put cost, the strategy still has a cost or tradeoff.

  • The hedge expires. The protection only lasts until the options expire.

  • Assignment is possible. Because the strategy includes a short call, the shares can be called away.

  • Strike selection matters. Choosing tighter strikes can mean more protection but less upside, while wider strikes can mean less protection but more room for gains.

Beginners should also understand that a collar does not eliminate risk. It reshapes risk. That is useful, but it is different from making a position safe.

Who a Collar May Fit

A collar may fit an investor who:

  • already owns a stock

  • wants downside protection for a limited time

  • is willing to cap upside in exchange for that protection

  • understands the basic mechanics of puts, calls, and assignment

It may be less appealing to someone who expects a large upside move and does not want to limit gains.

Final Takeaway

A collar is an options strategy that combines long stock, a protective put, and a covered call to create a more defined range of outcomes.

It can be useful for investors who want to stay in a stock position while reducing downside risk for a period of time. But that protection comes with a price: upside is limited, and the shares may be called away if the stock rises above the call strike.

For beginners, the most important idea is simple: a collar is not about getting something for nothing. It is about making a deliberate tradeoff between protection and upside.
