What is the purpose of Black-Scholes option pricing model?
Definition: Black-Scholes is a pricing model used to determine the fair price or theoretical value for a call or a put option based on six variables such as volatility, type of option, underlying stock price, time, strike price, and risk-free rate.
Why can the equity be priced as a call option?
Equity can be thought of as a call option on the company’s assets with a strike equal to the face value of the debt. This is true because of the concept of limited liability. Limited liability reduces the risk of loss for equity investors if the firm is valued less than the value of the outstanding debt.
Which valuation approach uses option pricing models?

Why does volatility increase price?
An increase in the volatility of the stock increases the value of the call options and also of the put option. This rule applies to call options and to put options. Higher volatility means higher upside risk or higher downside risk. When there is downside risk, the buyer of the call option will forego the premium.
How good is the Black-Scholes model?
