Quick Definition

What Is Options?
Options are financial derivatives that give the buyer the right—but not the obligation—to buy or sell an underlying asset at a predetermined price (strike price) within a specific time period.
Two Types of Options:
| Type | Right | Used For |
|---|---|---|
| Call | Buy at strike price | Bullish bets, income |
| Put | Sell at strike price | Bearish bets, protection |
Key Terms:
- Strike Price: Price at which option can be exercised
- Premium: Cost to buy the option
- Expiration: Date option expires worthless if not exercised
- In the Money (ITM): Option has intrinsic value
- Out of the Money (OTM): Option has no intrinsic value
- At the Money (ATM): Strike equals current price
Option Value Components:
- Intrinsic Value: Actual value if exercised today
- Time Value: Extra value from time remaining
- Total Premium = Intrinsic + Time Value
Basic Strategies:
| Strategy | View | Risk | Reward |
|---|---|---|---|
| Buy Call | Bullish | Premium paid | Unlimited |
| Buy Put | Bearish | Premium paid | Substantial |
| Sell Call | Neutral/Bearish | Unlimited | Premium |
| Sell Put | Bullish | Substantial | Premium |
Common Uses:
- Speculation: Leveraged bets on price direction
- Hedging: Protect portfolio from downside

- Leverage: Control more shares with less capital
