Options Basics
Understanding Options Contracts
An option gives you the right, but not the obligation, to buy or sell a stock at a set price before a set date. Think of it like a reservation: you pay a small fee now for the choice to act later. If the deal works out, you exercise the option. If it does not, you walk away and only lose the fee.
What Are Options
An option is a contract between two parties. The buyer pays a price called the premium for the right to buy or sell 100 shares of a stock at an agreed-upon price. The seller collects the premium and takes on the obligation to fulfill the contract if the buyer decides to use it.
- done_all Each contract covers 100 shares of the underlying stock
- done_all The most you can lose when buying an option is the premium you paid
- done_all Options expire on a specific date, unlike stocks which you can hold indefinitely
Calls vs Puts
There are only two types of options. A call gives you the right to buy shares at the strike price. A put gives you the right to sell shares at the strike price. You buy calls when you think a stock will go up and puts when you think it will go down or when you want to protect shares you already own.
Call Option
Right to buy 100 shares. Profitable when the stock rises above the strike price plus the premium.
Put Option
Right to sell 100 shares. Profitable when the stock falls below the strike price minus the premium.
Strike Price & Expiry
The strike price is the price at which you can buy or sell the underlying stock. The expiration date is the deadline to use that right. After expiration, the contract is worthless. Choosing the right strike and expiry means balancing cost against the probability that the stock reaches your target in time.
- done_all Closer strikes cost more but have a higher chance of profit
- done_all Further strikes are cheaper but need a bigger move to pay off
- done_all Longer expirations cost more because they give the stock more time to move
Premium & Pricing
The premium is the price you pay to buy an option. It is made up of intrinsic value, the amount the option is already worth, plus time value, the extra cost for the remaining time until expiration. Three things drive the premium higher: being closer to or past the strike price, having more time left, and higher stock volatility.
- done_all Intrinsic value exists only when the option is in the money
- done_all Time value shrinks every day and accelerates near expiration
- done_all Higher volatility means higher premiums for both calls and puts
Common Strategies
You do not need advanced strategies to use options effectively. A few straightforward approaches cover the most common goals: generating income, protecting a position, and betting on a big move.
- done_all Covered call — sell a call against shares you own to collect premium income
- done_all Protective put — buy a put on shares you own as insurance against a drop
- done_all Long straddle — buy a call and a put at the same strike to profit from a big move in either direction
