How do you value an option?
Options are valued using a theoretical model known as the "Black Scholes Model". The black scholes model prices options based on what are known as "Greeks", which are mathematical parameters of variables that influences the price of an option. However, this is a theoretical model because it cannot take into consideration the actual supply and demand of an option in the market and such forces does take the price of an option away from their theoretical value.
How are options priced?
Options are priced using a theoretical model known as a "Black Scholes Model". The black scholes model price options based on a set of mathematical parameters known as the "greeks" which covers the variables that influence options prices. However, this is only a theoretical model because it cannot take into consideration the actual demand and supply condition of specific options in the market. Actual demand and supply most often move the price of an option away from its theoretical value.
What is stochastic calculus?
The mathematical theory of stochastic integrals, i.e. integrals where the integrator function is over the path of a stochastic, or random, process. Brownian motion is the classical example of a stochastic process. It is widely used to model the prices of financial assets and is at the basis of Black and Scholes' theory of option pricing.
Is black better than yellow?
Yes black is better than yellow
Black Scholes Why do you think implied volatility from option prices diverge from their theoretical values?
Black-Scholes assumes the returns on prices follows a Normal (Gaussian) distribution. As the markets figured out this isn't the case, traders started demanding more money for options that were further out-of-the-money. This is called the "volatility smile".
Where can one find more information about black scholes calculator?
The black scholes calculator helps one to calculate basic Black-Scholes value for stock options. More information about the black scholes calculator can be found on the MyStockOptions website.
What are the main defects of the Black and Scholes model?
Black-Scholes makes the following assumptions (which are not valid in reality)constant volatility (not valid in the long term),efficient markets (hence no room for artbitrage),constant interest rates,log-normal returns,the option are imlicitly European and can only be exercized on their expiration dateno commission or transaction costs,and perfect market liquidity.

What kind of concept is black scholes model?
The Black Scholes model is a financial theory developed in 1973. It is used to determine the fair trading price of stock options. It's creators were Fisher Black, Robert Merton, and Myron Scholes.
Why does black scholes model only work on European options?
The black scholes equation is a boundary value problem which requires a terminal value condition (i.e. a known value at at known expiry date). As an American option can be excersised at any given time it must be modeled by a free boundary problem, which requires further analysis beyond the standard black scholes equations. You can however use Black scholes on other options eg. Asian
How do you calculate implied volatility using solver?
To calculate implied volatility using Solver, you need an options pricing model (such as Black-Scholes) and market data (including the option price, strike price, underlying asset price, risk-free rate, time to expiration, and any dividends). Build the pricing model in a spreadsheet, input the market data, and set the initial volatility value in Solver. Set the objective to match the calculated option price with the market price by changing the volatility cell. Run Solver to find the implied volatility that minimizes the difference between the calculated and market option prices.

What is black scholes model?
Black-Scholes describes the price of a financial instrument (otherwise known as a derivative) evolves over time with respect to several parameters. It is stated as a PDE (partial differential equation), but has analytical solutions (see the related link for an Excel spreadsheet with the analytical solution)
How do you explain the Black-Scholes formula?
Well...the way I'd explain it is as "the worst atrocity ever inflicted on the financial world." Which may not be specifically true, but it's not far off. Black-Scholes is a neat schoolhouse formula for determining The Proper Price To Trade Options At. Here's the problem: Black and Scholes assume there's only one risky item in an options transaction, and it's the stock. The money you use to buy it is considered riskless, and you can borrow as much as you want at a low interest rate. There are no transaction fees, and you can sell even a fraction of a share of stock. Unfortunately, none of those things are actually true. Those who believe in Black-Scholes believe you can put hard, scientifically-valid formulas to work to determine the price of something which can't actually be priced out that way, and they've cost people a LOT of money by doing it.
