Options Basics
About This Lesson
Options intimidate a lot of test-takers, but the SIE keeps them at a foundational level: what a call and a put are, how to read whether a position is bullish or bearish, the maximum gain and loss on each, and the mechanics of exercise and assignment. Get the vocabulary and the four basic positions down and the questions become very answerable. The heavy strategy math, spreads and straddles and the like, is Series 7 territory, not this exam.
What you'll cover
- calls and puts, the key terms, moneyness, and intrinsic versus time value
- the four single-leg positions and their max gain, max loss, and breakeven
- covered versus uncovered (naked) writing, and what makes naked calls so risky
- exercise, assignment, the role of the OCC, and the protective put as a hedge
This is the fifth chapter of the products module.
What Options Are: Moneyness & Value
An option is a contract that gives its buyer the right, but not the obligation, to buy or sell an underlying security at a set price within a set period of time. That asymmetry, all rights and no obligation for the buyer, is what separates an option from owning the stock outright. There are two kinds:
- Call option: the right to buy the underlying at the strike price. A call buyer is bullish, betting the price will rise.
- Put option: the right to sell the underlying at the strike price. A put buyer is bearish, betting the price will fall.
A few terms run through everything that follows: the premium is the price paid for the contract, the strike price is the price at which the underlying can be bought or sold, and the expiration date is the last day the option can be exercised. One more distinction matters for how an option can be used: an American-style option can be exercised any time before expiration, while a European-style option can be exercised only at expiration.
Call is in-the-money when market price > strike price.
Put is in-the-money when market price < strike price.
If an option is in-the-money at expiration, it has intrinsic value and will typically be exercised.
For Calls (right to BUY): ITM when stock price is above strike.
For Puts (right to SELL): ITM when stock price is below strike.
Think of it from the option holder's perspective: "Would I want to exercise this right now?"
A call with a $50 strike when stock is at $60, yes, buy at $50 and immediately worth $60. ITM.
A put with a $50 strike when stock is at $40, yes, sell at $50 when market is only $40. ITM.
Intrinsic value = the ITM amount. Time value = premium − intrinsic value. OTM options have zero intrinsic value, their entire premium is time value.
An option's premium is built from two parts, and separating them explains most of what options do.
Intrinsic value is the amount the option is in the money. It can be zero but never negative. For a call it is market price minus strike (when the market is above the strike); for a put it is strike minus market price (when the strike is above the market).
Time value is whatever is left of the premium above intrinsic value, the market's payment for the chance that the option grows more valuable before it expires:
Time Value = Premium − Intrinsic Value
Say XYZ is at $53 and a $50-strike call trades at $5. Its intrinsic value is $53 − $50 = $3, so the remaining $2 is time value. As expiration nears, that time value erodes, a process called time decay, until at expiration the option is worth only its intrinsic value, if any. That steady bleed is why options are called wasting assets.
An investor who is bearish on a stock would most likely purchase which of the following?
XYZ stock is trading at $42. An XYZ 45 put option is trading at $5. What is the intrinsic value and time value of this option?
Option Positions & Their P&L
One of the most common exam questions simply asks whether a position makes money when the stock rises or falls. There are four single-leg positions, and they split cleanly into bullish and bearish:
- Bullish (profit when the stock rises): a long call (the right to buy at the strike) and a short put (the obligation to buy if assigned, taken on in exchange for the premium).
- Bearish (profit when the stock falls): a long put (the right to sell at the strike) and a short call (the obligation to sell if assigned).
The pattern is worth memorizing: buying a call or selling a put is bullish; buying a put or selling a call is bearish.
This table is the single most important thing to memorize in the options chapter. Each of the four positions has a defined maximum gain, maximum loss, and breakeven:
| Position | Max Gain | Max Loss | Breakeven |
|---|---|---|---|
| Long Call (bullish) | Unlimited | Premium paid | Strike + Premium |
| Short Call (bearish/neutral) | Premium received | Unlimited | Strike + Premium |
| Long Put (bearish) | Strike − Premium | Premium paid | Strike − Premium |
| Short Put (bullish/neutral) | Premium received | Strike − Premium | Strike − Premium |
The shortcut is "Call Up, Put Down": a call's breakeven is the strike plus the premium (the price has to rise to get there), and a put's breakeven is the strike minus the premium (the price has to fall). Notice the two unlimited entries, a long call has unlimited gain, and a short (naked) call has unlimited loss.
Plug in any strike price, premium, and market price, see your profit/loss, max gain, max loss, and breakeven instantly.
- Call buyers have the right to buy; put buyers have the right to sell. Buyers pay premium, sellers receive it.
- Max loss for a long call = premium paid. James can never lose more than $300.
- Call breakeven = Strike + Premium. "Call Up", add the premium to the strike price.
- Profit = Intrinsic Value − Premium. At expiration: (Stock Price − Strike − Premium) × 100.
An investor buys a call option with a strike price of $60 and pays a premium of $4. What is the breakeven point and maximum loss?
An investor sells a put option with a $45 strike and collects a $3 premium. What is the maximum gain and maximum loss on this position?
Covered & Uncovered Options
Writing (selling) an option can be covered or uncovered, and the difference is entirely about risk.
- Covered call: writing a call while owning the underlying stock. If the call is assigned, the shares are already in hand to deliver, so the risk is limited. This is the conservative, income-oriented use of options.
- Uncovered (naked) call: writing a call without owning the stock. If assigned, the writer has to buy shares at whatever the market demands in order to deliver them, so the loss potential is unlimited, the riskiest of the common options positions.
- Covered put: writing a put while holding the cash to buy the shares or while short the stock.
A covered call strategy involves which of the following positions?
Exercise, Assignment & the OCC
Knowing that a call is a right to buy is the start; the SIE also tests what happens mechanically when that right is used.
To exercise is the holder's action. A holder who exercises a call buys 100 shares at the strike from the assigned writer; a holder who exercises a put sells 100 shares at the strike to the assigned writer. With American-style options (most equity options) the holder can exercise any time before expiration; with European-style options (most index options) only at expiration.
Assignment is the flip side, the writer's obligation. When a holder exercises, the Options Clearing Corporation (OCC) randomly selects a writer of the same series to fulfill it. An assigned call writer must sell 100 shares at the strike (even if the market price is far higher), and an assigned put writer must buy 100 shares at the strike (even if the market is far lower).
1. The OCC guarantees all listed options contracts and handles the assignment process. If you see "who guarantees options?" the answer is always OCC.
2. Exercise by exception: ITM options are automatically exercised at expiration. A holder who does NOT want to exercise an ITM option must submit explicit instructions ("do not exercise").
3. American vs. European: Most equity options are American style (exercise anytime). Most index options are European style (exercise at expiration only). The exam tests this distinction frequently.
Opening an Options Account
Before a customer can trade options, the firm has to clear a few specific steps, and the SIE tests the details:
- The customer must receive the Options Disclosure Document (ODD) at or before the time the account is approved.
- A Registered Options Principal (ROP) must approve the account.
- The signed options agreement must be returned to the firm within 15 days of approval.
- The firm must assess the customer's financial background, investment objectives, and options experience for suitability.
At expiration, an investor holds a call option with a $50 strike price. The underlying stock closes at $50.25. What happens to this option under OCC rules?
Which organization is responsible for guaranteeing listed options contracts and managing the exercise and assignment process?
An investor holds a European-style index call option that is currently in-the-money with two weeks until expiration. The investor wants to capture the profit immediately. What can they do?
Protective Put
The SIE covers a few basic strategies where an option is paired with a stock position to manage risk. The one it asks about most is the protective put (called a married put when the stock and put are bought together).
The setup is simple: long stock plus a long put. The investor owns the shares and buys a put on them as insurance. If the stock drops, the put gains value and offsets the loss on the shares; if the stock keeps rising, the put simply expires and the shares run free. Compared with a covered call, which caps the upside at the call strike, the protective put keeps all of the upside. The cost is the premium paid for the put, which is just the price of the insurance.
For a protective put with stock cost S, put strike K, and premium P:
- Maximum gain: unlimited, the stock can rise indefinitely while the put expires worthless.
- Maximum loss: (S − K) + P, the put floors the effective sale price at the strike, so the worst case is the drop from purchase price to strike plus the premium paid.
- Breakeven: S + P, the stock has to rise just enough to recover the premium.
For example, buy 100 shares of XYZ at $50 and a 45-strike put for a $2 premium. The most you can lose is ($50 − $45) + $2 = $7 a share, or $700, no matter how far XYZ falls, while everything above your $52 breakeven is yours to keep.
Chapter Essentials
An option is the right, not the obligation, to buy (a call) or sell (a put) at the strike. Buying a call or selling a put is bullish; buying a put or selling a call is bearish. The premium splits into intrinsic value (the in-the-money amount) and time value (everything else, which decays to zero by expiration).
The four positions each have a fixed max gain, max loss, and breakeven, with "Call Up, Put Down" setting the breakeven (strike plus premium for calls, strike minus premium for puts), and a long call and a naked call holding the two unlimited outcomes. Writing covered limits risk; writing naked does not. The OCC guarantees every listed contract and assigns writers at random, and a protective put (long stock plus long put) buys downside insurance while keeping the upside.
The reliable options gotchas:
• Match the view to the position. Bullish means long call or short put; bearish means long put or short call. A bearish investor buys a put.
• Call up, put down. A call's breakeven is strike plus premium; a put's is strike minus premium. A $60 call bought for $4 breaks even at $64, with a max loss of the $400 premium.
• Intrinsic value is never negative. A put's intrinsic value is strike minus market, so a 45 put with the stock at $42 has $3 of intrinsic value; the rest of the premium is time value.
• Naked calls have unlimited loss. A covered call (long stock plus short call) is limited risk; an uncovered call is the one with unlimited downside.
• The OCC is always the answer to "who guarantees listed options?" It also assigns writers randomly and auto-exercises any option in-the-money by $0.01 or more at expiration (exercise by exception).
• European means expiration only. A European-style option cannot be exercised early; to capture a gain before expiration, the holder sells the option in the market instead.
• Protective put keeps the upside. Long stock plus a long put caps the loss at (stock cost − strike) + premium while leaving the upside open, unlike a covered call.
Calls, puts, max gain, max loss, breakeven, just the options concepts FINRA tests, nothing more.
