Study Notes
Profit Equations for Options
- Profit from buying a call option: Profit = Nc [Max(0, St - X) - C]
- Nc = Number of call contracts, St = stock price at expiration, X = exercise price, C = option premium.
- Profit from writing a call option: Profit = Max(0, St - X) + C
- Implies Nc = -1.
- Profit from buying a put option: Profit = Np [Max(0, X - St) - P]
- Np = Number of put contracts, P = option premium.
- Profit from writing a put option: Profit = Max(0, X - St) + P
- Implies Np = -1.
Strategies Based on Market Outlook
-
Bullish Strategies: Buying stock, taking a call, or writing a put.
- Aim to profit from rising stock prices.
-
Bearish Strategies: Shorting stock, writing a call, or taking a put.
- Aim to profit from declining stock prices.
Specific Options Strategies
-
Covered Call: Write a call option while owning the stock.
- Profit if St < X: Profit = Stock Price - Price Paid + Received from Call.
- Profit if St > X: Profit = Exercise Price - Price Paid + Received from Call.
-
Protective Put: Buy stock and a put option to limit losses.
- If St < X: Profit = Exercise Price - Price Paid - Premium Paid.
- If St > X: Profit = Current Stock Price - Price Paid - Premium.
Spread Strategies
-
Bull Spread: Buy and sell different call options with different exercise prices (X1 < X2).
- Profit equation: Intrinsic Value of Buying Call - Cost + Premium Received.
- Bear Spread Using Calls: Buy a call with higher exercise price and write a lower one.
- Bear Spread Using Puts: Buy put with higher exercise price and sell a lower one. Calculate max and min profits accordingly.
Straddle and Straps Strategies
-
Straddle: Buy equal amounts of calls and puts, benefiting from significant price movements in either direction.
- Max Profit: Infinite. Min Profit: Total Premium Paid.
- Straps: Buy two calls and one put. More upside exposure.
- Strips: Buy two puts and one call. More downside exposure.
European vs. American Options
- European options can only be exercised at expiration; American options can be exercised any time before expiration.
- Call intrinsic values differ based on whether they're American or European.
Time Value and Option Premiums
- Time value is the potential for the option to gain value before expiration, influenced by volatility and time remaining.
- Option Premium = Intrinsic Value + Time Value.
Minimum and Maximum Option Values
- Call option minimum varies for American and European: based on the spot price (So) or the present value of the exercise price (PV(X)).
- Put option minimum is always 0; maximum is the exercise price.
Impact of Dividends, Interest Rates, and Volatility
- Dividends impact intrinsic value, potentially decreasing call option value.
- Interest rates affect option valuations; higher rates generally lower put option values and increase call option values.
- Higher volatility increases the value of both call and put options due to increased potential for profitable outcomes.
Exercise and Profitability Expectations
- The taker of a long put or call hopes the respective exercise price exceeds the stock price or vice versa.
- The writer of a short call or put hopes the stock price remains below or above the exercise price respectively.
Trading Strategies with Mispriced Options
- Long an underpriced call option to sell stock for profit as prices rise.
- Profit from an overpriced put option by selling the option before prices decline.
Summary of Key Calculations
- Recognize critical formulas for profit based on strategies, time to expiration, exercise prices, and market conditions.
- Use intrinsic value and premiums to guide trading decisions across different options types.### Options Trading Strategies
- Selling a put option is done when the put is overpriced in the market, resulting in selling at a higher price.
- Buying a put option is done when the put is underpriced in the market, resulting in buying at a lower price.
- Selling a call option is done when the call is overpriced in the market, resulting in selling at a high price.
Common Options Trading Terms
- A call option gives the buyer the right to buy the underlying asset at a specified price.
- A put option gives the buyer the right to sell the underlying asset at a specified price.
Options Trading Positions
- A straddle involves buying a call and put option at the same time, with the same exercise price and time to expiration.
- A protective put involves buying a put option and buying shares, typically when the investor is bullish on the market.
- A covered call involves selling a call option and buying shares, typically when the investor is bearish on the market.
Advanced Options Trading Strategies
- A strap involves buying two calls and buying one put, typically when the investor is bullish on the stock.
- A strip involves buying two puts and buying one call, typically when the investor is bearish on the stock.
The Greeks
- The Greeks are factors that impact the sensitivity of an option's value.
Delta
- Delta measures the sensitivity of an option's value due to movements in the stock price.
- Delta = Change in option value / small change in stock price.
- Delta ranges from 0 to 1, with 0 indicating the option is "out of the money" and 1 indicating the option is "in the money".
Gamma
- Gamma measures the sensitivity of delta, influenced by movements in the stock price.
- Gamma is highest when the option is "at the money".
- Gamma is also higher when closer to expiration, but drops to 0 at expiration.
Vega
- Vega measures the sensitivity of an option's value due to changes in volatility.
- Vega = Change in Option Value / Change in Implied Volatility (standard deviation).
- Vega is highest when the option is "at the money".
Rho
- Rho measures the sensitivity of an option's value due to changes in the risk-free rate.
- Rho = Changes in option value / change in risk-free rate.
Theta
- Theta measures the sensitivity of an option's value due to changes in the time to expiration.
- Theta = changes in options value / changes in time to expiration.
- Theta is higher when the time to expiration is longer, and lower when the time to expiration is shorter.
