From Operating Room to Options: Smart Trading Strategies for Physicians

Alpha Sentinel is a software platform, not a registered investment adviser. This article is educational, not investment advice. Full disclaimer at the end of this post.

It is the Friday before a long case, and a colleague at the scrub sink mentions that he sells options against his stock portfolio for extra income. It sounds tidy: a payment into the account and nothing to do while you are working. The mechanics are more demanding. Options are contracts with expiration dates, and different strategies built from them carry very different costs, risks and attention requirements. This post describes five well-known option strategies in neutral terms: what each one is, how it works, what it costs or gives up, where the risks sit, and why the time it demands matters for someone with an unpredictable calendar.

Key Takeaways

• Every option strategy is a combination of calls and puts, each with a strike price and an expiration date.
• Covered calls and cash-secured puts collect premium but accept an obligation, and both can end in assignment.
• Protective puts and collars are built around shares already owned, and each has a cost or a trade-off.
• Vertical spreads limit both the possible gain and the possible loss, and they still have an expiration date.
• Expiration, assignment and price moves operate on their own schedule, whether or not anyone is watching a screen.

What are the basic building blocks?

A call option gives its holder the right, but not the obligation, to buy a stock at a fixed price, the strike, on or before a set expiration date. A put option gives the right to sell at the strike. The price paid for either is the premium. The seller of an option collects that premium and takes on the obligation if the buyer exercises the contract, which is called assignment. Every strategy below is some arrangement of these pieces.

Unlike a share of stock, an option has a limited life. As expiration approaches, an option loses time value, a pattern known as time decay, which works against buyers and in favor of sellers.

What is a covered call?

A covered call pairs shares the investor already owns with a call sold against them. The seller collects the premium. In exchange, the seller agrees to sell the shares at the strike if the stock finishes above it and the buyer exercises.

What it gives up is the upside above the strike: if the stock climbs well past that price, the shares can be called away at the lower, agreed price. The premium offers only a small cushion if the stock falls, and the shares keep their full downside exposure. The main risks are that missed upside and assignment, which can arrive before expiration and can mean parting with shares the owner intended to keep.

What is a cash-secured put?

A cash-secured put is a put sold while holding enough cash to buy the shares at the strike. The seller collects the premium and takes on the obligation to buy the stock at the strike if the buyer exercises.

If the stock stays above the strike, the put typically expires worthless and the seller keeps the premium. If the stock falls below the strike, the seller may be assigned and purchase shares at a price above where they now trade. The cost is that cash is set aside for the length of the contract, and the loss on the shares is not capped by the premium received. Assignment can come early, so the purchase can happen on a day when the seller is in the operating room.

What is a protective put?

A protective put combines shares already owned with a put bought on the same stock. The put gives the right to sell the shares at the strike, which sets a floor under the sale price for as long as the contract lasts.

The cost is the premium, which is paid whether or not the put is ever used. If the stock does not fall, the premium is simply gone, and it reduces the gain from the shares. The main risk is that the put expires and the floor disappears, so someone using the structure repeatedly keeps paying premium to keep it in place.

What is a collar?

A collar combines shares already owned, a protective put bought below the current price, and a call sold above it. The premium collected from the call offsets some or all of the cost of the put.

The trade-off is symmetrical. The put sets a floor, and the call sets a ceiling, so the range of outcomes on the shares is narrowed on both sides. What is given up is the upside beyond the call's strike. The risks include assignment on the short call and the need to deal with both contracts when they expire, which may not fall on the same day.

What is a vertical spread?

A vertical spread is made of two options of the same type and expiration with different strikes: one bought and one sold. A bull call spread, for example, buys a call at one strike and sells a call at a higher strike.

Because the sold option offsets part of the cost of the bought one, the net cost is lower than buying the call alone. In return, the potential gain is capped at the difference between the strikes less the net cost, and the maximum loss is the net amount paid. The risks are that both legs can lose value together, that time decay works on the position, and that the short leg can be assigned early. A spread is a defined-risk structure, but it still expires.

Why does a demanding schedule matter for each of these?

The strategies differ in how much attention they ask for, and the common thread is that the contracts follow the calendar rather than the investor's availability.

• Expiration dates. Every strategy above has one, and what happens at expiration depends on where the stock sits relative to the strikes. Several of the structures involve more than one contract, each of which has to be tracked.
• Assignment. Sellers of options, including in covered calls, cash-secured puts, collars and spreads, can be assigned before expiration. It does not wait for a convenient moment.
• Monitoring. A price that moves sharply during a ten-hour shift changes the value of every position. What the holder can do about it, and when, is a question each strategy answers differently.

What might an illustrative walk-through look like?

This is an illustration of a process, not a real person, not a recommendation, and not a forecast.

Imagine a surgeon who is curious about options and reads about the five strategies above. For each one, she writes down four things: the worst outcome, the date on which something is decided, what happens if the contract is assigned while she is in a case, and how often the position would need her attention. She notices that the defined-risk structures make the worst outcome easy to state, while the ones involving sold options add assignment to the list, and that every structure has a date attached to it. The exercise gives her a written comparison of what each strategy costs, risks and demands.

Frequently Asked Questions

What are common option strategies?

Covered calls, cash-secured puts, protective puts, collars and vertical spreads are among the best known. Each combines calls and puts with particular strikes and expiration dates, and each has its own cost, trade-off and main risk.

Which option strategies involve the risk of assignment?

Any strategy that includes a sold option can be assigned, which covers covered calls, cash-secured puts, collars and vertical spreads. Assignment can happen before expiration and means being required to sell or buy shares at the strike.

How much time do option strategies take?

The time depends on the structure. All of them have expiration dates, and those with sold options also carry assignment, so none is entirely hands-off. Expiration, assignment and price moves keep operating whether or not you are looking.
