Iron Collar: Put Floor, Call Cap, Net Credit

Published January 23, 2023
Iron Collar: Put Floor, Call Cap, Net Credit

What are the characteristics of this option strategy?

Iron collar positions combine a protective put and a covered call on stock the trader already owns, so the shares are fenced in on both sides. The protective put is bought at the money or out of the money and sets a floor: below its strike, further declines in the shares are matched by gains in the put. The call is sold at the money or out of the money and sets a cap: above its strike, further gains in the shares are matched by losses on the call. The premium received for the call pays for part or all of the put, which is what makes the structure cheap, and what the trader gives up in exchange is the upside above the call strike.

Is this a bullish, bearish or neutral strategy?

The iron collar options strategy can be used in either a bullish, bearish or neutral market. Generally, the strategy is used in a bullish market when cost of put is low and cost of call is high resulting in net premium credit. It also provides some downside protection while partly capturing the upside in the stock. In a bearish market, it may be used to protect against a major decline in the underlying stock and still provide some premium income from call option.

Is this a beginner or an advanced option strategy?

This is an advanced option strategy. Because it involves two different option strategies (protective put and covered call) it can be somewhat complicated to execute and manage. The short call is a real obligation: if the stock runs past that strike the shares can be assigned away, which is a tax event as well as a capped gain, so the strikes need to be chosen with the whole position in mind rather than leg by leg.

In what situation will I use this strategy?

The iron collar strategy is generally used when a trader is looking to reduce their downside risk with a stock they own while still generating premium income. It can also be used when one is expecting to have the stock stay within a certain price range and wants to take advantage of that range.

Where does this strategy typically fall in the range of risk-reward and probability of profit?

The risk-reward of the iron collar strategy varies depending on at which strike prices the protective put and covered call are purchased/sold. Both ends are defined once the strikes are set: the most that can be lost is the fall from the purchase price down to the put strike, plus the net cost of the two options, and the most that can be made is the rise up to the call strike, less that same net cost. Inside the two strikes the position behaves like the stock. The probability of profit varies with where the strikes are placed and is not improved by the collar; the collar trades away part of the upside for a floor under the downside.

How is this strategy affected by the greeks?

The greeks will affect the Iron Collar Strategy in a variety of ways. Generally, the position delta stays clearly positive but lower than owning the shares outright, because the long put and the short call each subtract from the +100 delta of the stock. Vega and theta largely offset: the long put is long vega and loses time value, while the short call is short vega and gains it, so the net of the two is small and its sign depends on how far each strike sits from the money and on the skew between them. The dominant exposure is the stock itself, not the greeks of the two options.

In what volatility regime (i.e VIX level) would this strategy be optimal?

The volatility level matters less for the Iron Collar Strategy than the shape of the skew, because one option is bought and the other is sold. When volatility is low both options are cheaper: the protective put costs less, but the call you sell also brings in less premium, so the net cost of the collar depends on the skew between the two strikes rather than on the volatility level alone.

How do I adjust this strategy when the trade goes against me? And how easy or difficult is this strategy to adjust?

Adjusting the Iron Collar Strategy when the trade goes against the trader is relatively easy. If the stock price decreases, then the protective put will increase in value, offsetting the losses in the stock. If the stock price increases, the short call you sold rises in value and works against you, capping your gain at the call strike; you can buy it back and roll it higher if you want to reclaim upside, at a cost.

Where does this strategy typically fall in the range of commissions and fees?

The commissions and fees for the Iron Collar Strategy will depend on the broker being used. Generally, brokers will charge a per-contract fee for each option purchased and sold, and some brokers may also charge a commission for stock trades.

Is this a good option income strategy?

The Iron Collar Strategy can be used as an income strategy, but it is not necessarily the best option strategy for this purpose. This is because the strategy involves both buying and selling options, and the overall return on investment may not be as high as with some other option strategies.

How do I know when to exit this strategy?

When exiting the Iron Collar Strategy, the trader should consider several factors. First, they should consider the current price of the stock and the time to expiration of the options. If the stock is close to the strike price of either the put or the call, it may be wise to close out the position. Additionally, if the time to expiration is getting short, the trader should assess the probability of the stock being in-the-money at expiration and decide whether or not to close the position.

How will market makers respond to this trade being opened?

Market makers see only the two option legs, not the shares behind them, so they hedge the put and the call as ordinary orders and are not much affected by the strategy as a whole. The trader should keep in mind that the market maker takes the opposite side of both legs and prices them off the bid-ask spread, so a collar that looks close to free on mid prices can cost real money once both legs are filled.

What is an example (with calculations) of this strategy?

For example, if a trader owned 100 shares of ABC Stock at $50 per share and wanted to execute an iron collar strategy, they could purchase a $45 Put option and sell a $55 Call option. Assuming the cost of the Put option is $2 per share and the premium received for the Call option is $1 per share, the initial cost of the trade would be $100 ($200 for the Put option minus the $100 received from the Call option). Note that this pairing is a net debit of $1 per share, not the net credit described earlier; whether a collar opens for a credit or a debit depends on where the two strikes are set and on the skew between them. Between $45 and $55 the trader keeps the change in the share price less that $1 per share, so the position breaks even at $51. At $55 and above the profit stops at $400, the $500 gain on the shares less the $100 net cost of the options. At $45 and below the loss stops at $600, the $500 fall in the shares plus the $100 net cost, and the put floor prevents it going further no matter how far the stock falls.
