Here's an overview of key price metrics for stocks, bonds, and futures options:
**Stock Option Price Metrics:**
1. **Theoretical Value (or Black-Scholes Model Value):** This is the estimated fair value of an option calculated using the Black-Scholes model, which takes into account the underlying stock price, strike price, time to expiration, volatility, interest rates, and dividends.
2. **Premium:** The price paid for an option contract.
3. **Bid and Ask:** The highest price a buyer is willing to pay (bid) and the lowest price a seller is willing to accept (ask) for an option contract.
4. **Volatility** (or IV - Implied Volatility): A measure of the expected volatility of the underlying stock price, which affects the option's price.
5. **Delta:** The rate of change of the option's price with respect to changes in the underlying stock price.
6. **Greeks**:
* **Delta**: measures the rate of change of the option's price with respect to changes in the underlying stock price.
* **Gamma** (or Convexity): measures the rate of change of the option's delta with respect to changes in the underlying stock price.
* **Theta**: measures the rate of change of the option's price with respect to time (time decay).
* **Vega**: measures the rate of change of the option's price with respect to changes in volatility.
7. **Moneyness**: Measures how "in-the-money" or "out-of-the-money" an option is, based on the strike price compared to the market price of the underlying stock.
**Bond Option Price Metrics:**
1. **Theoretical Value**: Estimated fair value of a bond option calculated using the Binomial model or a similar method.
2. **Maturity Date**: The final date at which the option expires or is exercised.
3. **Strike Price** (or Strike Yield): The interest rate or yield level at which the option can be exercised.
4. **Coupon or Yield**: The interest rate paid by the bond.
5. **Market Price**: The current market price of the underlying bond.
6. **Volatility**: Measures the expected changes in interest rates, which affects bond option prices.
7. **Duration**: Measures a bond's sensitivity to interest rate changes, which affects bond option prices.
**Futures Option Price Metrics:**
1. **Theoretical Value**: Estimated fair value of a futures option calculated using the Black-Scholes model or the Binomial model.
2. **Strike Price**: The price at which the futures contract can be exercised.
3. **Underlying Futures Contract**: The specific futures contract that the option is written on.
4. **Margin Requirement**: The minimum amount required to buy or sell a futures contract, such as a stock index or commodity.
5. **Volatility**: Measures the expected changes in the underlying commodity or stock index price, which affects futures option prices.
6. **Irrunizance**: Measures the sensitivity of the option to changes in the underlying futures contract price.
7. **Open Interest**: Measures the number of open futures contracts, which can affect market sentiment and option prices.
Keep in mind that these metrics may not be applicable in all situations and may overlap across different options types. It's also worth noting that some of these terms might have different names or slightly different definitions depending on the market and the context.
