Contract sheet with a hinged arrow rising then falling, representing options glossary terms

These 20 terms cover options: the two contract types, what a contract costs, and the handful of strategies the SIE tests. Everything builds from the call option, the right to buy at a set price, and the put option, the right to sell. Once those are automatic, the covered call is the strategy the exam returns to most, because it tests whether you can combine a stock position and an option position in one question. Learn the vocabulary in the order listed and the strategy questions become arithmetic.

Call Option

A call option gives its holder the right, not the obligation, to buy 100 shares of the underlying stock at the strike price any time up to and including expiration. The seller (writer) of the call takes on the matching obligation: if the holder exercises, the writer must deliver the shares.

The SIE® tests calls at the identification level. A long call is the basic bullish position: the buyer profits when the stock rises above the strike price. Maximum loss for the buyer is the premium paid, while maximum gain is unlimited, because there is no ceiling on a stock’s price. The short call is the mirror image, bearish, with gain capped at the premium received and loss theoretically unlimited if uncovered. Every listed contract covers 100 shares and is issued and guaranteed by the Options Clearing Corporation (OCC).

Example: an investor buys 1 XYZ 50 call at 3, paying $300. If XYZ climbs to $60, the holder can buy 100 shares at $50 that are worth $60, a $1,000 value against $300 paid, for a $700 profit. Breakeven is the strike plus the premium: $53. If XYZ stays at or below $50, the call expires worthless and the loss is the $300 premium, no more.

Put Option

A put option gives its holder the right, not the obligation, to sell 100 shares of the underlying stock at the strike price any time up to and including expiration. The writer of the put is obligated to buy those shares if the holder exercises.

The SIE® keeps returning to one sorting question: who is bullish and who is bearish. A long put is the bearish position: it gains value as the stock falls below the strike price. It can also be protective: an investor who owns the stock buys a put as insurance against a decline. A short put is bullish (or neutral), because the writer profits by keeping the premium when the stock stays at or above the strike. Maximum gain on a long put is substantial but not unlimited (a stock can only fall to zero) while maximum loss is the premium paid.

Example: an investor buys 1 ABC 80 put at 2, paying $200. If ABC drops to $70, the holder can buy shares at $70 in the market and sell them at $80 through the put, $1,000 of intrinsic value, for an $800 profit. Breakeven is the strike minus the premium: $78. If ABC stays at or above $80, the put expires worthless and the loss is $200.

Premium

The premium is the price of an option contract, what the buyer pays and the writer receives. It is quoted per share, so a premium of 3 means $300 for one contract covering 100 shares.

The SIE® tests the premium two ways. First, its components: premium equals intrinsic value plus time value. Intrinsic value is the amount the option is in the money; time value is everything above that, reflecting the time remaining until expiration. Second, its role in risk questions: the premium is the maximum possible loss for any option buyer, call or put, and the maximum possible gain for any option writer. When a question asks what a long option holder can lose, the answer is the premium paid, never more.

Example: XYZ trades at $64, and an XYZ 60 call is quoted at a premium of 7.25. The call is in the money by $4 ($64 stock price minus $60 strike), so intrinsic value is $4 and time value is the remaining $3.25. The buyer pays $725 for the contract, and $725 is the most that buyer can lose no matter what the stock does.

An option with no intrinsic value still commands a premium. It is all time value, and that time value erodes to zero at expiration.

Strike Price

The strike price (or exercise price) is the fixed price at which an option holder can buy the underlying stock (a call) or sell it (a put), no matter where the stock trades. It is set when the contract is created and does not change over the option’s life.

Nearly every option calculation the SIE® asks runs through the strike. Moneyness compares the stock price to the strike: a call is in the money when the stock is above the strike, a put when the stock is below it. Breakeven builds on the strike too: for a call it is strike plus premium; for a put, strike minus premium. Maximum gain and loss answers for both buyers and writers all start from the same anchor. If you can locate the stock price relative to the strike, most option questions resolve quickly.

Example: an investor buys an XYZ 55 call at 3. The strike is $55, so breakeven is $58. With XYZ at $62, the call is in the money by $7: the holder can exercise and buy at $55 stock worth $62. With XYZ at $54, the call is out of the money, and exercising would make no sense: nobody pays $55 for stock available at $54.

Expiration Date

The expiration date is the day an option contract ceases to exist. After it passes, the holder’s right to exercise is gone. Standard listed equity options expire on the third Friday of the expiration month.

The SIE® uses expiration to test the idea that options are wasting assets. Unlike a share of stock, which can be held indefinitely, an option has a built-in clock. The time value portion of the premium erodes as expiration approaches and reaches zero on the expiration date itself. At that point an option is worth only its intrinsic value; and if it has none, it expires worthless. The exam also distinguishes contract lengths: standard listed options are short-dated, typically running out to about nine months, while LEAPS (Long-term Equity AnticiPation Securities) carry expirations of up to roughly three years. Longer time until expiration means more time value and a higher premium, all else equal.

Example: in March, an investor buys an XYZ June 50 call at 4 with the stock at $50. The entire $400 premium is time value. If XYZ is still at $50 on the June expiration date, the call has no intrinsic value and no time remaining. It expires worthless, and the buyer’s loss is the $400 premium.

Intrinsic Value

Intrinsic value is the amount by which an option is in the money, the built-in exercise value you get by comparing the stock price to the strike. For a call, it is stock price minus strike; for a put, strike minus stock price. Intrinsic value is never negative: an option that is at or out of the money simply has an intrinsic value of zero.

The SIE® asks you to compute it directly. A typical question gives a stock price, a strike, and a quoted premium, then asks for the option’s intrinsic value, or for its time value, which is the premium minus intrinsic value. The two components always sum to the full premium, so once you find one, the other is subtraction.

Example: XYZ trades at $64 and the XYZ 60 call is quoted at 7.25. Intrinsic value is $64 − $60 = $4 per share ($400 per contract). The remaining $3.25 of the premium is time value. Now flip it: with XYZ at $64, a 60 put has zero intrinsic value (the right to sell at $60 is worthless when the market pays $64) so its entire premium is time value.

One more anchor: intrinsic value ignores what anyone paid for the option. It is a snapshot of stock versus strike, nothing else.

Practice it: options practice questions

Time Value

Time value is the portion of an option’s premium above its intrinsic value, the amount buyers pay for the time remaining until expiration. The formula is simple: time value = premium − intrinsic value.

The SIE® tests this as a two-step calculation. First find the intrinsic value (how far the option is in the money), then subtract it from the quoted premium; whatever is left is time value. The exam also tests the concept behind the number: time value exists because more time means more chance for the stock to move in the holder’s favor, which is why options are called wasting assets. It erodes as the expiration date approaches, a process often called time decay, and reaches zero at expiration, when an option is worth exactly its intrinsic value and nothing more.

Example: XYZ trades at $64 and the XYZ 60 call carries a $7.25 premium. Intrinsic value is $4 ($64 − $60 strike), so time value is $7.25 − $4.00 = $3.25 per share, or $325 on the 100-share contract. An out-of-the-money option makes the math even shorter: with zero intrinsic value, its entire premium is time value.

A longer-dated contract on the same stock and strike will carry more time value, which is why LEAPS cost more than near-month options.

Practice it: options practice questions

In the Money

An option is in the money (ITM) when exercising it would have value: a call is ITM when the stock price is above the strike, and a put is ITM when the stock price is below the strike. The amount by which an option is in the money is its intrinsic value.

The SIE® tests moneyness as a pure comparison of stock price to strike price. And its favorite trap is the premium. Moneyness ignores what the investor paid, so in the money does not mean profitable. A question will show an option that is clearly ITM, and the wrong answer choices will invite you to factor in the cost of the contract. Keep the two ideas separate: moneyness is stock versus strike; profit is moneyness versus premium paid.

Example: an investor buys an XYZ 50 call at 5, paying $500. With XYZ at $53, the call is in the money by $3. But the position is losing money, because $3 of intrinsic value is worth less than the $5 premium paid. The stock must reach $55 (strike plus premium) before the buyer breaks even. The call is ITM at $53, at breakeven at $55, and profitable only above that.

The same logic runs in reverse for puts: a 50 put is in the money at any stock price below $50.

Practice it: options practice questions

Out of the Money

An option is out of the money (OTM) when exercising it would have no value: a call is OTM when the stock price is below the strike, and a put is OTM when the stock price is above the strike. An out-of-the-money option has zero intrinsic value: its entire premium, if any, is time value.

The SIE® tests this as a classification skill. A question gives you a stock price and a strike and asks you to label the option in, at, or out of the money. The rule to carry in: calls want the stock above the strike, puts want it below. Anything else is out of the money. And the premium the investor paid plays no part in the label. Moneyness is a comparison of two prices, not a profit calculation.

Example: an investor holds a $75 put with the stock trading at $82. The right to sell at $75 is worthless when the open market pays $82, so the put is out of the money, by $7. It does not matter whether the investor paid 1 or 4 for the contract; the classification is the same. If the option is still OTM at expiration, it expires worthless and the holder loses the premium paid.

At the boundary, a stock trading exactly at the strike makes the option at the money, not out of it.

Covered Call

A covered call is writing (selling) a call option against 100 shares of the underlying stock the writer already owns. Because the shares are on hand to deliver if the call is exercised, the writer’s obligation is “covered”: there is no need to buy stock in the open market at any price.

The SIE® frames the covered call as the conservative income strategy, in contrast to the naked (uncovered) call, whose potential loss is unlimited. The writer collects the premium as income and keeps it whether or not the call is exercised. The trade-off is a capped upside: if the stock climbs past the strike price, the shares are called away at the strike, and any gain beyond it belongs to the call holder. Maximum gain is therefore the premium plus the stock’s appreciation up to the strike. The premium also provides a small cushion on the downside, but only to the extent of the premium; the writer still bears the full risk of owning the stock below that.

Example: an investor owns 100 shares of XYZ bought at $40 and writes an XYZ 45 call at 2, collecting $200. If XYZ rises to $50, the stock is called away at $45. Maximum gain: $500 of appreciation ($40 to $45) plus the $200 premium, or $700.

Uncovered (Naked) Call

An uncovered (naked) call is a call option written by an investor who does not own the underlying stock, leaving the writer exposed to unlimited potential loss if the stock rises.

The SIE® returns to this strategy repeatedly for one reason: it is the riskiest basic option position. A covered call writer who is exercised against simply delivers shares already owned. An uncovered writer must first buy the stock at the market price, whatever that price is, to deliver at the strike. Because a stock’s price has no ceiling, neither does the potential loss. That is why exam questions call naked call writing suitable only for the most sophisticated, risk-tolerant investors, and why firms require their highest level of options approval before permitting it.

Run the numbers. An investor writes one XYZ 60 call for a $3 premium without owning XYZ. The stock jumps to $90 and the writer receives an assignment notice: buy 100 shares at $90, deliver them at $60. That is a $3,000 loss on the stock, offset only by the $300 premium, a net loss of $2,700. At $120, the net loss would be $5,700. Maximum gain is always just the premium collected, and the breakeven point sits at strike plus premium: $63.

Protective Put

A protective put is a put option purchased by an investor who owns the underlying stock, hedging the position against a decline.

The SIE® frames the protective put as the insurance strategy. The stockholder pays a premium and in return gains the right to sell at the strike price no matter how far the stock falls. Downside is capped; upside stays open, reduced only by the premium paid. Two formulas do most of the exam work: maximum loss equals the stock’s cost minus the strike, plus the premium, and the position’s breakeven point equals the stock’s cost plus the premium.

Put numbers on it. An investor buys 100 shares of XYZ at $50 and buys one XYZ 45 put for $2, a $200 premium. If the stock collapses to $30, the investor can exercise the put and still sell at $45. The loss is locked at $5 per share on the stock plus the $2 premium, $7 per share, or $700, no matter how low XYZ goes. If instead the stock climbs to $70, the investor keeps the full gain minus the $200 premium; the stock must reach $52 for the combined position to break even.

Exam questions often contrast this with writing a covered call: the call brings in income but caps upside, while the protective put costs money and preserves it.

Breakeven Point

The breakeven point is the stock price at which an option position produces neither a profit nor a loss at expiration.

The SIE® tests two formulas, and they cover every single-option position: calls break even at strike plus premium; puts break even at strike minus premium. The detail the exam likes most is that the breakeven is identical for the buyer and the writer of the same contract. The premium one side pays is the premium the other side collects, so the crossover price is shared; only the direction of profit differs.

Work one through. An investor writes a 650 put and collects a $14 premium. Breakeven: 650 − 14 = $636. At exactly $636 at expiration, the writer’s $14 loss on the intrinsic value is offset by the $14 collected; and the buyer’s $14 gain is offset by the $14 paid. Below $636 the buyer profits and the writer loses; at $636 or above, the writer keeps up to the full premium. Questions usually pair this math with maximum gain and maximum loss: here the writer’s maximum gain is $1,400 and maximum loss is $63,600 if the stock goes to zero.

The same arithmetic anchors strategy questions on the uncovered call and the protective put, so learn the two formulas cold.

Options Clearing Corporation (OCC)

The Options Clearing Corporation (OCC) is the organization that issues and guarantees every listed option contract in the United States.

The SIE® tests one distinction above all: the OCC, not the exchange, is the issuer and guarantor of listed options. Exchanges such as Cboe provide the marketplace where options trade; the OCC stands behind the contracts themselves. Once a trade is executed, the OCC becomes the counterparty to both sides, effectively the buyer to every seller and the seller to every buyer. A call holder never has to worry whether some specific writer can perform, because the OCC guarantees performance.

The OCC also standardizes contract terms. Strike prices, expiration dates, and the 100-share contract size are all set by the OCC; only the premium is left to the market. When a holder exercises, the exercise notice goes to the OCC, which selects a member firm with a short position at random, the first step in assignment. The OCC also publishes the Options Disclosure Document, the risk booklet customers must receive at or before options account approval.

A typical exam question asks who issues and guarantees listed options and offers the exchange, the brokerage firm, and the writer as distractors. The answer is always the OCC.

Exercise

To exercise an option is to invoke the contract’s right: buying the underlying stock at the strike price for a call, or selling it at the strike price for a put.

The SIE® tests exercise as the moment an option stops being a right on paper and becomes a stock trade. A call holder who exercises buys 100 shares at the strike; a put holder who exercises sells 100 shares at the strike. The exercise notice goes to the Options Clearing Corporation, which passes the obligation to a writer through assignment.

The mechanic the exam pairs with this: exercising an equity option creates a regular-way stock transaction, and regular-way stock trades settle T+1, one business day after exercise. Listed equity options are American-style, so the holder can exercise at any time up to and including expiration, not just on the final day.

Example: an investor holds one XYZ 50 call and XYZ is trading at $58. Exercising means buying 100 shares at $50 (paying $5,000 for stock worth $5,800) with the stock delivered against payment the next business day. Note that exercising is a choice, not a requirement; most holders simply sell the option instead, since selling captures any remaining time value that exercise gives up.

Assignment

Assignment is the notice that obligates an option writer to fulfill the contract because a holder has exercised, delivering stock at the strike for a call writer, or buying stock at the strike for a put writer.

The SIE® tests the allocation chain more than the concept itself. When a holder decides to exercise, the notice goes to the Options Clearing Corporation. The OCC selects a member firm carrying a short position in that series at random. The firm then allocates the notice to one of its short customers by random selection or first-in, first-out (FIFO). The distractor the exam plants: assigning to the customer with the largest short position. That method is never permitted: memorize random and FIFO as the acceptable answers.

For the assigned writer, assignment is not optional. A writer short one XYZ 60 call who is assigned must deliver 100 shares at $60, buying them at the market first if the position is uncovered. An assigned put writer must buy 100 shares at the strike regardless of the market price. The resulting stock trade settles regular way, T+1.

Assignment risk is why writing options carries obligations while buying carries rights. The buyer chooses, the writer responds.

American-Style Option

An American-style option can be exercised at any time up to and including its expiration date.

The SIE® tests exercise style as a two-way contrast. American-style means the holder may exercise whenever it suits them during the life of the contract. European-style means exercise is possible only at expiration. Listed equity options, the standard calls and puts on individual stocks, are American-style; European-style is typical of index options. The names have nothing to do with geography; both styles trade on U.S. exchanges.

The nuance worth locking in: style restricts exercise, not trading. Holders of either style can buy or sell the option itself in the market at any time before expiration. Style only answers one question: when can the holder convert the right into a stock transaction?

Example: an investor buys an XYZ March 40 call in early January. XYZ spikes to $55 in late January. Because the option is American-style, the holder can exercise immediately and buy 100 shares at $40, no need to wait for March. One common reason to exercise early is to own the shares before an upcoming ex-dividend date, since option holders receive no dividends.

Practice it: options practice questions

European-Style Option

A European-style option can be exercised only at expiration, not before.

The SIE® tests this as the mirror image of the American-style option, which is exercisable at any time up to and including expiration. The pairing to memorize: listed equity options are American-style; European-style is typical of index options, such as options on the S&P 500. The names carry no geographic meaning: European-style contracts trade on U.S. exchanges all day long.

That last point is the trap the exam sets. Style limits exercise, not trading. A European-style holder who wants out before expiration is not stuck; they simply sell the option in the market and capture its current premium. Only the ability to exercise, to convert the contract into its settlement value, is confined to expiration.

Example: in May, an investor holds a June index call that is well in the money. She cannot exercise in May, because the contract is European-style. She can, however, sell the call in May at its market premium, or hold it and exercise at June expiration. Index options also settle in cash rather than delivering a basket of stocks, which is part of why the restricted exercise window works.

Options Disclosure Document (ODD)

The Options Disclosure Document (ODD) is the risk-disclosure booklet (formally titled “Characteristics and Risks of Standardized Options”) that a customer must receive before trading options.

The SIE® tests one thing about the ODD above everything else: delivery timing. The ODD must be furnished at or before the time the account is approved for options trading. Not at the first trade, not within 15 days of the first trade, at or before approval. The document is published by the Options Clearing Corporation and explains how listed options work and what can go wrong: the strategies, the risk of losing the entire premium, and the obligations that come with writing.

The exam often frames this as an account-opening sequence. Put the steps in order: the customer provides financial information, the ODD is delivered, a registered options principal approves the account for options trading, and only then can the first order be accepted. The signed options agreement, the customer’s acknowledgment of the rules, comes back within 15 days after approval; if it never arrives, the account is limited to closing transactions.

A typical question offers “before the first trade” as a tempting distractor. It fails because approval must come before any trade, and the ODD must come no later than approval.

LEAPS

LEAPS, Long-term Equity AnticiPation Securities, are listed options with expirations of roughly two to three years, far longer than the nine months or less of a standard listed option.

The SIE® tests LEAPS as a one-difference product: the expiration is long, and everything else is standard. One contract still covers 100 shares. The contracts are still issued and guaranteed by the Options Clearing Corporation. Equity LEAPS are still American-style, exercisable at any time up to and including expiration. A question that suggests LEAPS cover a different share amount or trade outside the listed-options system is describing a distractor, not the product.

The practical consequence the exam draws out is time value. More time until expiration means more time for the stock to move, so LEAPS carry higher premiums than short-term options at the same strike. With XYZ at $50, a three-month 55 call might trade at $2 while a two-year 55 LEAPS call on the same stock trades at $8. The extra $6 is pure time value. That longer runway also means LEAPS lose time value slowly at first; the decay accelerates as expiration finally approaches.

Investors use LEAPS to take a multi-year view on a stock with less capital than buying 100 shares outright, while risking the entire premium if the view is wrong.
