Question 1

What is options pricing and how is it calculated?

Accepted Answer

Options pricing determines the fair value of an option contract. The Black-Scholes model is the most common method, using stock price, strike price, time to expiration, volatility, risk-free rate, and dividend yield. Our calculator supports multiple pricing models including Binomial Tree and Monte Carlo simulation.

Question 2

What are the Greeks in options trading?

Accepted Answer

The Greeks measure how option prices change with various factors: Delta (price sensitivity), Gamma (delta sensitivity), Theta (time decay), Vega (volatility sensitivity), and Rho (interest rate sensitivity). Understanding Greeks is essential for options risk management.

Question 3

What is the difference between European and American options?

Accepted Answer

European options can only be exercised at expiration, while American options can be exercised at any time before expiration. American options are typically worth more due to this flexibility. Our calculator supports both styles.

Question 4

How does volatility affect options prices?

Accepted Answer

Higher volatility increases options prices because it increases the probability of the option finishing in-the-money. Vega measures this sensitivity. Volatility is a key input in options pricing models and is often the most difficult to estimate accurately.

Question 5

What is time decay (Theta)?

Accepted Answer

Time decay (Theta) measures how much an option's value decreases as time passes, all else equal. Options lose value as expiration approaches, with decay accelerating near expiration. This is why many options traders prefer shorter-term strategies.
