Options trading

Options are derivatives that give the right (not obligation, for the buyer) to buy or sell an underlying asset at a set strike price by expiration. They are used for leverage, hedging, income, and expressing views on direction or volatility. This section points you to book notes and to a concise summary and tips.

Core Concepts (Quick Reference)

Definitions

• Call: Right to buy the underlying at the strike by expiration. Bullish view; max loss = premium; upside potentially unlimited.

• Put: Right to sell the underlying at the strike by expiration. Bearish view or hedge; max loss = premium; max gain when underlying → 0.

• Strike: Price at which the option can be exercised. Expiration: Date after which the option expires. Premium: Price paid/received (intrinsic + time value).

• ITM / ATM / OTM: In-the-money (call: underlying > strike; put: underlying < strike). At-the-money ≈ strike. Out-of-the-money = opposite of ITM.

The Greeks

Greek	Meaning	Practical use
Delta	Sensitivity to underlying price	Direction exposure; approx. hedge ratio
Gamma	Rate of change of delta	Acceleration of P< risk for short options
Theta	Time decay per day	Long options lose; short options gain
Vega	Sensitivity to implied volatility	Long options gain when IV rises; short lose

Implied Volatility (IV)

• IV is the volatility implied by option prices. High IV = expensive options (good to sell premium, costly to buy). Low IV = cheap options (good to buy). Compare to historical volatility and your view.

• IV crush: After events (e.g. earnings), IV often drops. Long options can lose value even with a favorable stock move.

Basic Strategy Types

• Directional: Long call (bullish), long put (bearish), bull/bear spreads. Limited risk; defined reward for spreads.

• Income / neutral: Covered call, cash-secured put, iron condor, credit spreads. Collect premium; define max loss.

• Volatility: Long straddle/strangle (profit from big move); short straddle/strangle or iron condor (profit from range). Risk varies—short vol can be very risky.

• Hedging: Protective put (limit downside on stock); collar (cap upside and downside).
