Core Notes (Read like a checklist)

Built at true SIE level: definition + intuition + common traps. Open each section.
1) What an Option Is must know
  • An option is a derivative contract based on an underlying asset such as a stock or index.
  • A call gives the buyer the right to buy the underlying at the strike price before or at expiration.
  • A put gives the buyer the right to sell the underlying at the strike price before or at expiration.
  • The buyer (holder) has a right. The seller (writer) has an obligation if assigned.
Fast memory line: Call = right to buy • Put = right to sell
2) Contract Size, Premium, and Basic Terms numbers
  • Most listed equity option contracts normally represent 100 shares of the underlying stock.
  • The premium is the option price quoted per share, but the total cash amount is usually premium × 100.
  • The main contract terms are underlying, strike price, expiration date, and premium.
Mini example: A premium of $3.20 usually means $320 for one standard equity contract.
3) Long vs Short Options Positions core language
  • Long call: bullish position; buyer wants the stock price to rise.
  • Long put: bearish or protective position; buyer benefits if the stock falls.
  • Short call: seller collects premium but may face large risk if the stock rises sharply.
  • Short put: seller collects premium but may have to buy the stock at the strike if assigned.
Exam shortcut: Long means you bought the option. Short means you wrote / sold the option.
4) The Four Inputs Students Must Read First practical
  • Underlying: which stock or index the option is based on.
  • Strike price: the contract price for buying or selling the underlying.
  • Expiration date: the last date or period the contract remains alive.
  • Premium: the market price of the option contract.
Read any option quote in this order:
Underlying → Call or Put → Strike → Expiration → Premium
5) Moneyness: ITM, ATM, OTM must know
  • A call is in the money when the stock price is above the strike price.
  • A put is in the money when the stock price is below the strike price.
  • At the money means stock price is about equal to strike price.
  • Out of the money means the option has no intrinsic value right now.
Fast memory line: Calls like up. Puts like down.
6) Intrinsic Value vs Time Value big concept
  • Intrinsic value is the amount the option is in the money.
  • Time value is the extra premium above intrinsic value, reflecting time remaining and uncertainty.
  • As expiration gets closer, options generally lose time value; this is often called time decay.
Call intrinsic value
max(Stock − Strike, 0)
Put intrinsic value
max(Strike − Stock, 0)
7) Break-Even and Basic Profit Logic formula basics
  • For a long call, break-even at expiration is strike + premium.
  • For a long put, break-even at expiration is strike − premium.
  • For a buyer of an option, the maximum loss is generally the premium paid.
  • A long call has substantial upside if the stock rises. A long put gains as the stock falls, but the stock cannot fall below zero.
Common trap: Students often confuse payoff with profit. Profit must account for the premium paid.
8) Exercise, Assignment, American vs European test favorite
  • Exercise is the holder using the option right.
  • Assignment is the writer being required to perform the contract obligation.
  • American-style options can generally be exercised any time up to expiration.
  • European-style options can generally be exercised only at expiration.
  • Equity options usually involve stock delivery; many index options are cash-settled.
Fast memory line: Holder exercises. Writer gets assigned.
9) Equity Options vs Index Options recognition
  • Equity options are tied to individual stocks and often settle with shares.
  • Index options are tied to a market index and are commonly cash-settled.
  • The SIE outline expects students to recognize the difference, not to master advanced pricing.
Simple contrast: Equity option → single company exposure. Index option → broad market or sector exposure.
10) Two Basic Strategies the SIE Loves important
  • Covered call: own the stock and sell a call against it. Often viewed as a conservative income strategy.
  • Protective put: own the stock and buy a put for downside protection.
  • The SIE often tests whether a strategy is mainly for income, protection, or speculation.
Covered call
Stock ownership + call sale
Goal: income, limited downside cushion, capped upside
Protective put
Stock ownership + put purchase
Goal: downside protection
11) Leverage, Risk, and Options Approval regulatory basics
  • Options provide leverage, meaning a relatively small premium can control a larger exposure.
  • Leverage can magnify gains, but it can also magnify losses and make losses happen quickly.
  • Brokerage firms must approve customers for options trading, and options customers receive the Options Disclosure Document (ODD).
  • Approval can differ by strategy level; basic purchases of calls and puts may be approved before more complex strategies.
SIE-level point: Know that options trading needs specific approval and comes with special disclosure requirements.
12) What the SIE Usually Wants — and What It Usually Does Not scope
  • The SIE expects basic option vocabulary, position recognition, simple break-even logic, and basic strategies.
  • The SIE does not usually require deep work with Black-Scholes, binomial trees, advanced Greeks, or professional trading models.
Good study target: Be able to explain calls, puts, strike, premium, expiration, ITM/OTM, covered call, protective put, exercise, and assignment in plain English.
13) High-Frequency Options Exam Traps read twice
  • Call buyer has the right to buy; put buyer has the right to sell.
  • Seller / writer has the obligation, not the buyer.
  • Long means bought; short means wrote / sold.
  • Calls are in the money when stock is above strike; puts are in the money when stock is below strike.
  • Buyer’s maximum loss is generally the premium paid.
  • Covered call is not the same as naked call.
  • Exercise and assignment are opposite sides of the same contract event.
Practice technique: After answering a question, say aloud: “Who has the right? Who has the obligation?” That catches many mistakes.
