Options strategies

Introduction

Options strategies use call and put options, sometimes together with stocks or other securities, to create specific risk and return profiles. Investors can use options to hedge existing positions, generate premium income, gain leveraged exposure, or express views about price direction and volatility.

The flexibility of options is also what makes them complex. A strategy’s outcome can depend on the underlying price, strike prices, time remaining until expiration, volatility, dividends, interest rates, and whether positions are closed or assigned before expiration.

Options can involve substantial risk. Before using them, investors need to understand both the individual contracts and the combined payoff of the complete strategy.

Calls and puts

The buyer pays the premium for the option’s rights. The seller receives that premium in exchange for taking on contractual obligations. This difference between buying and selling options is fundamental to understanding their risks.

Why investors use options strategies

Options can alter the payoff of an investment without requiring the same exposure as buying or selling the underlying asset directly. A put can provide downside protection, for example, while a sold call can generate premium income in exchange for giving up some upside.

Other strategies combine multiple options to define a range of possible outcomes. Spreads can limit both potential profit and potential loss, while volatility strategies may depend less on a simple bullish or bearish view.

No structure eliminates tradeoffs. Protection has a cost, premium income comes with obligations, and leverage can magnify losses as well as gains.

Common options strategies

Covered calls

A covered call combines a long stock position with a short call. It is often used by an investor who is willing to sell shares at the strike price in exchange for receiving an option premium.

The premium can modestly cushion a decline in the stock, but the investor continues to bear most of the downside risk. If the stock rises far above the strike, the call can substantially limit the investor’s gain.

Calling the strategy “covered” refers to the fact that the investor owns the shares that can be delivered if assigned. It does not mean the position is protected from loss.

Protective puts

A protective put combines ownership of an asset with a long put option. The put gives the investor the right to sell at the strike price, creating a floor on the asset’s value during the option’s life, subject to the premium paid and contract terms.

This resembles insurance in an economic sense because the investor pays for downside protection. If the asset never falls enough for the put to become valuable, the premium can expire with little or no value.

Repeatedly buying protection can therefore create a meaningful cost over time.

Vertical spreads

A vertical spread combines options of the same type and expiration but different strike prices. One option is purchased and another is sold.

The premium from the sold option helps offset the cost of the purchased option. In exchange, the strategy limits the maximum payoff. This can create a more clearly defined risk and reward profile than buying an option by itself.

Spreads still require careful management. Assignment can occur on short options, and closing one leg while leaving another open can materially change the risk of the position.

Time decay and volatility

An option’s value depends partly on how much time remains until expiration. All else equal, the time value of an option generally declines as expiration approaches, although the rate of change is not constant.

Expected volatility is also important. Higher expected volatility generally increases option premiums because larger future price movements become more plausible.

As a result, an investor can be correct about the direction of the underlying asset and still lose money on an option if the move is too small, occurs too late, or is offset by changes in volatility and time value.

Leverage in options

Options can provide significant economic exposure for a relatively small premium or margin requirement. This creates leverage.

For an option buyer, the premium paid can be lost entirely if the option expires worthless. Although the buyer’s loss on a simple long call or long put is generally limited to the premium and transaction costs, that can still represent a 100% loss of the amount invested in the option.

Option sellers can face very different risks. An uncovered call can have theoretically unlimited loss potential because the underlying asset’s price has no fixed upper limit.

Assignment and exercise

Exercise occurs when an option holder uses the contractual right to buy or sell the underlying asset. Assignment is the corresponding obligation imposed on an option seller.

Exercise rules depend on the contract. U.S. listed equity options are generally American-style and can be exercised before expiration, while some index options use European-style exercise and can only be exercised at expiration.

Investors with short option positions therefore need to understand the exercise style, settlement method, expiration process, and possibility of early assignment.

Options strategy comparison

Major risks of options strategies

Options can expire worthless, lose value rapidly, or create obligations through assignment. Strategies with multiple legs can also behave differently than expected when one position is exercised or closed.

Liquidity matters because wide bid-ask spreads can make entering and exiting positions expensive. Contract size also matters. Standard equity option contracts generally represent 100 shares, so even one contract can create substantial exposure.

Taxes and brokerage requirements can add further complexity. Options approval levels, margin requirements, and permitted strategies vary by broker and account type.

What to understand before using options

Investors should be able to identify the maximum potential profit, maximum potential loss, breakeven points, expiration date, assignment risk, and the circumstances under which the strategy changes.

It is also important to evaluate the strategy as a whole. Looking only at the premium received or the low upfront cost of an option can hide the larger economic exposure.

Options are advanced instruments. They can serve legitimate investment and risk-management purposes, but their complexity and leverage make understanding the contract mechanics particularly important.

Key takeaways

• Options strategies combine calls, puts, and sometimes underlying securities to create specific payoff profiles.
• Option buyers receive contractual rights, while option sellers take on obligations in exchange for premiums.
• Covered calls, protective puts, and vertical spreads each involve different tradeoffs between cost, protection, income, and upside.
• Time to expiration and expected volatility can materially affect option values.
• Leverage can cause option positions to gain or lose value rapidly.
• Exercise, assignment, liquidity, contract specifications, and maximum loss should be understood before entering a strategy.
