Frequently asked questions
What is the Black-Scholes model?
A mathematical model developed by Fischer Black and Myron Scholes to calculate the theoretical price of options based on underlying asset price, volatility, time, and interest rates.
How accurate are Black-Scholes calculations?
The model provides good theoretical estimates but assumes constant volatility and interest rates. Real market conditions may cause actual prices to differ from calculated values.
What's the difference between call and put prices?
Call options give the right to buy at strike price, while puts give the right to sell. Their prices vary inversely with underlying asset movements.
