Section 5.1 — Overview of Options
🧩 What is an Option?
An option is a contract between two parties: a buyer and a seller (writer).
It gives the buyer the right, but not the obligation, to buy or sell a specific security at a set price (the strike price) before a set date (expiration).
Options are derivative securities — their value is derived from the price of an underlying asset (like a stock).
1. ⚖️ Types of Options:
Call Option: Right to buy the underlying security at the strike price.
Put Option: Right to sell the underlying security at the strike price.
2. 🏛 Regulator:
The Options Clearing Corporation (OCC) regulates and standardizes all exchange-traded option contracts — ensuring they’re easily tradable.
🧮 Key Terms
Term / Meaning
Strike Price / The price at which the underlying security can be bought or sold.
Expiration / Date the contract ends (standard options expire on the third Friday of the month at 11:59 PM).
Premium / Price of the option (paid by the buyer, received by the seller).
Contract Size / 1 contract = 100 shares of the underlying security.
Underlying Security / The stock or asset the option is based on.
🧍♂️ The Buyer (“Long,” “Holder,” or “Owner”):
Pays the premium.
Has rights (not obligations).
Can exercise the contract (buy or sell depending on call or put).
Will only exercise when it’s profitable (makes economic sense).
Opening Buy: When a buyer first purchases the contract.
Closing Sale: When the buyer sells the contract later.
🧍♀️ The Seller (“Short” or “Writer”):
Receives the premium.
Has an obligation if the buyer exercises.
Opening Sale: When the seller writes the contract.
Closing Purchase: When the seller buys it back to close their position.
