Options Trading Lecture Notes

Overview of Options Trading

  • Trillions of dollars traded daily on the stock market.
  • Options trading allows investors to bet on stock prices without owning shares directly.
  • A free options trading guide is available (details later).

What is Options Trading?

  • Involves buying and selling options contracts.
  • Options give the holder the right, but not the obligation, to buy or sell an underlying asset at a specific price before a specific time.
  • Similar to a voucher allowing a future purchase at today’s price.

Key Terms and Concepts

Call Option

  • Definition: Gives the holder the right to buy an asset at the strike price.
  • Example: Buying a call option for a smartphone to lock in today’s price for future purchase.
  • Scenario: Stock at $100, buy call option at $105 for a $3 premium. If stock rises to $120, exercise option for profit; if it drops, lose premium.

Put Option

  • Definition: Gives the holder the right to sell an asset at the strike price.
  • Scenario: Stock at $100, buy put option at $95 for a $3 premium. If stock drops to $80, exercise option for profit; if it rises, lose premium.

Expiration Date

  • Options become worthless if not exercised by expiration.
  • More time before expiration increases value; value decreases as expiration date approaches (time decay).

Strike Price

  • The agreed-upon price for buying/selling the asset if the option is exercised.
  • In the Money: Call option strike price below market price; put option strike price above market price.
  • Out of the Money: Call option strike price above market price; put option strike price below market price.
  • At the Money: Strike price equals market price.

Premium

  • The fee paid by the option buyer to the seller for the option contract.

The Greeks

  • Used to gauge options premiums and measure risks:
    • Delta: Sensitivity to price changes.
    • Gamma: Delta’s sensitivity to price changes.
    • Theta (Time Decay): Sensitivity to the passage of time.
    • Vega: Sensitivity to changes in volatility.
    • Rho: Sensitivity to interest rate changes.

Reasons for Trading Options

  1. Limiting Downside Risk: Maximum loss is the premium paid, unlike stock ownership.
  2. Leverage: Smaller investment can control larger stock positions, leading to potentially higher returns with capped losses.

Options Trading Strategies

Buying Calls (Long Calls)

  • Scenario: Bullish on stock expecting price increase.
  • Example: Buy a call for Rocket Corp at $55 for a $2 premium; if stock rises to $70, profit calculation: (70 - 55 - 2) = $13.

Buying Puts (Long Puts)

  • Scenario: Bearish on stock expecting price drop.
  • Example: Buy a put for Rocket Corp at $45 for a $2 premium; if stock falls to $30, profit calculation: (45 - 30 - 2) = $13.

Covered Calls

  • Selling a call option on an owned stock to generate income.
  • Example: Own Blue Sky Technologies at $100, sell call at $110 for a $3 premium; if stock stays under $110, keep premium.

Protective Puts

  • Buying a put option to protect gains on stock investments.
  • Example: Own Green Earth Innovations at $150, buy put at $140 for a $5 premium; if stock drops to $120, exercise put to limit loss.

Conclusion

  • Covered calls and protective puts balance risk and reward.
  • Covered calls generate income but might limit upside; protective puts limit losses.
