The Right to Buy vs the Right to Sell

A call option gives its buyer the right, but not the obligation, to buy 100 shares of the underlying stock at a fixed strike price until the option expires. A put option gives its buyer the right, but not the obligation, to sell 100 shares at the strike price. Call buyers profit when the stock rises above the strike, and put buyers profit when it falls below.

Every option has two sides. The buyer pays a premium and receives the right, while the seller, known as the writer, collects the premium and takes on the obligation to deliver or buy the shares if the buyer exercises. That gives four basic positions: long call, long put, short call and short put.

Those four positions sit behind almost every options question in the investment vehicle section of the exam. For the full route from the exam to a career in advice, our complete guide to how to become an investment adviser representative covers every step.

How Options Contracts Work

A listed equity stock option covers 100 shares of the underlying stock. Its price, the premium, is quoted per share, so a premium of $3 costs $300 per contract.

Each option has a strike price, the price at which the shares change hands if the option is exercised, and an expiration date. Most listed equity options are American-style, so the buyer can exercise at any time before expiration, and the Options Clearing Corporation stands between buyers and writers to guarantee performance.

Options are derivatives, because their value comes from the price of the underlying stock. The Series 65 Exam Preparation course at FRC covers calls, puts and the strategies built from them in the depth the exam expects.

What a Call Option Does

A call is a bet on, or protection against, a rising price. The call buyer locks in the right to buy at the strike price, so if the stock climbs above the strike, the call gains value.

The buyer’s maximum loss is the premium paid, which is lost if the stock is at or below the strike at expiration. The maximum gain is unlimited, because there is no ceiling on how high a stock can rise. The breakeven is the strike price plus the premium.

The call writer takes the opposite position. The writer keeps the premium if the call expires worthless but must sell shares at the strike if assigned. As our article on the risk an uncovered call writer faces explains, a writer who does not own the shares faces unlimited risk.

What a Put Option Does

A put option is a bet on, or protection against, a falling price. The put buyer locks in the right to sell at the strike price, so if the stock drops below the strike, the put gains value.

The buyer’s maximum loss is again the premium paid. The maximum gain is large but limited, because a stock can fall only to zero: it equals the strike price minus the premium, multiplied by 100. The breakeven is the strike price minus the premium.

The put writer collects the premium but must buy shares at the strike if assigned. The writer’s maximum loss is the strike minus the premium, reached if the stock falls to zero, and the maximum gain is the premium.

Call Option vs Put Option at a Glance

Worked Example One: Buying a Call

XYZ trades at $50. An investor buys one XYZ January 55 call for a premium of $2, paying $200. The breakeven is $55 plus $2, or $57.

Step one: suppose XYZ closes at $60 at expiration. The call is worth its intrinsic value, $60 minus $55, or $5 per share. Step two: subtract the premium paid: $5 minus $2 is a profit of $3 per share, or $300 per contract.

Step three: suppose instead XYZ closes at $52. The call is out of the money and expires worthless, so the investor loses the full $200 premium. Step four: any closing price between $55 and $57 recovers part of the premium but still produces a net loss.

Worked Example Two: Buying a Put

With XYZ at $50, a different investor buys one XYZ January 45 put for a premium of $2, paying $200. The breakeven is $45 minus $2, or $43.

Step one: suppose XYZ falls to $40 at expiration. The put is worth $45 minus $40, or $5 per share. Step two: subtract the premium: $5 minus $2 is a profit of $3 per share, or $300 per contract.

Step three: the best case is a fall to zero. The put would then be worth the full $45 strike, and after the $2 premium the profit is $43 per share, or $4,300. Step four: if XYZ stays above $45, the put expires worthless and the loss is the $200 premium.

Intrinsic Value and Time Value

An option’s premium has two parts. Intrinsic value is the amount by which the option is in the money: for a call, the stock price minus the strike, and for a put, the strike minus the stock price. If the result is negative, intrinsic value is zero.

Time value is everything else, the premium minus the intrinsic value. It reflects the chance that the option gains value before expiration, and it shrinks as expiration approaches, a process called time decay.

With XYZ at $50, a 45 call priced at $7 has intrinsic value of $5 and time value of $2. A 45 put priced at $1 is out of the money, so its entire $1 premium is time value. Factors such as volatility, time to expiration and interest rates drive time value, and our article on rho in option pricing explains how rates affect calls and puts in opposite directions.

The Four Basic Positions

Long call: bullish, maximum loss is the premium, maximum gain is unlimited, breakeven is strike plus premium. Short call: bearish or neutral, maximum gain is the premium, maximum loss is unlimited if uncovered, breakeven is strike plus premium.

Long put: bearish, maximum loss is the premium, maximum gain is strike minus premium, breakeven is strike minus premium. Short put: bullish or neutral, maximum gain is the premium, maximum loss is strike minus premium, breakeven is strike minus premium.

Notice the pairs. The buyer and writer of the same option share the same breakeven, and one side’s gain is the other side’s loss. Our guide to long vs short options sets out how each position mirrors its opposite.

Using Calls and Puts to Manage Risk

Options are not only for speculation. A protective put lets an investor who owns shares buy the right to sell them at a set price, limiting the loss if the stock falls while keeping the upside if it rises.

A covered call lets an investor who owns shares sell a call against them to collect premium income. The trade-off is that the shares may be called away if the stock rises above the strike, capping the upside.

Both are forms of hedging. The put buys insurance against a fall, and the call sells away some upside in exchange for income, which is why both appear regularly in suitability questions.

Leverage and Risk for the Buyer

Options give buyers leverage. In Example One, the investor controlled 100 shares worth $5,000 for a $200 premium, and a $10 rise in the stock produced a 150 percent return on the money invested.

Leverage works both ways. If the stock fails to move enough before expiration, the buyer can lose the entire premium, even if the forecast direction was correct but the timing was wrong.

That combination of high potential return and a high chance of total loss on any single trade is why options are suitable only for investors who understand them and can afford to lose the premium. It is also why the account rules described below exist.

Account Approval and Disclosure

Before a customer can trade options, the firm must approve the account under FINRA Rule 2360. The customer must receive the options disclosure document, and a registered options principal must approve the account based on the customer’s objectives, experience and financial situation. The disclosure document explains the characteristics and risks of standardised options in plain language before any trading begins.

Firms approve accounts for different levels of strategy. Buying calls and puts and writing covered calls sit at the lower levels, while uncovered writing requires the highest approval and additional risk disclosure.

Our FINRA rules quick reference on duties and conflicts places the options rule alongside the suitability and conduct rules that govern every recommendation.

The Memory Aid

Remember this line: call up, put down. Call buyers want the price to go up, and put buyers want it to go down.

For breakevens, remember that calls add and puts subtract. A call’s breakeven is the strike plus the premium, and a put’s breakeven is the strike minus the premium.

For moneyness, remember that a call is in the money when the stock is above the strike and a put is in the money when the stock is below it. The two are always mirror images.

Exam Traps to Avoid

The first trap is giving the writer a right. The buyer holds the right, and the writer holds the obligation, for both calls and puts.

The second trap is reversing moneyness for puts. A put with a $45 strike is in the money when the stock trades at $40, not at $50. The third trap is calling the put buyer’s maximum gain unlimited: it is limited to the strike minus the premium, because the stock cannot fall below zero.

The fourth trap is forgetting the contract multiplier. Premiums are quoted per share, so multiply by 100 for the dollar amount. The fifth trap is picking a long call as the only bullish strategy: writing a put is also bullish, because the writer profits if the stock stays above the strike.

A Client Scenario

A client holds 500 shares of a technology company bought years ago at $40, now trading at $120. He is worried about a sharp fall after the company’s next earnings report but does not want to sell and trigger a large capital gain.

The adviser explains that buying five protective puts with a $110 strike would give him the right to sell all 500 shares at $110, limiting his loss below that level for the life of the options. The cost is the premium, which works like an insurance payment.

Alternatively, if the client mainly wanted extra income and was willing to sell at a higher price, five covered calls at a $130 strike would pay premium now but cap his upside at $130. Because his priority is protection, the puts are the better match, a recommendation grounded in his objectives and risk tolerance, the core of every suitability assessment.

Practice Questions to Test Yourself

Question one: What right does the buyer of a put option receive? The right, but not the obligation, to sell 100 shares of the underlying stock at the strike price until expiration.

Question two: An investor buys one ABC 70 call at $4. What is the breakeven? $74, the strike price plus the premium. The investor profits only if ABC rises above $74 by expiration.

Question three: An investor buys one ABC 70 put at $4. What is the maximum gain? $6,600, the strike minus the premium, $66, multiplied by 100. It is reached if ABC falls to zero.

Question four: ABC trades at $65. Which is in the money: the 70 call or the 70 put? The 70 put, because the stock is below the strike. The 70 call is out of the money.

Question five: Which two basic positions are bullish? Buying a call and writing a put. Both profit if the stock rises or stays above the strike.

Key Points to Retain

A call gives the buyer the right to buy 100 shares at the strike price, and a put gives the buyer the right to sell. Call buyers are bullish and put buyers are bearish, and both risk only the premium paid.

The call buyer’s gain is unlimited and the put buyer’s gain is limited to the strike minus the premium. Calls break even at strike plus premium and puts at strike minus premium, writers hold the obligations, and options accounts require approval under FINRA Rule 2360.
