# Option theory in valuation

The rapid growth of interest in option theory is probably due to the abundance of relevant applications in the financial marketplace. The precision of the option valuation models relies primarily on preference-free, enforceable arbitrage conditions.

First, these arbitrage conditions are reviewed, and the related partial equilibrium hedging models are discussed. Next, the more general equilibrium, non-hedging models are briefly surveyed.

## Option Valuation: Theory and Empirical Evidence

Then, the differences in options on equity, debt, currency, and futures are mentioned, along with other applications of option theory.

Most of the empirical work testing the arbitrage boundaries has been related to equities, where the market data originated.

Furthermore, valuation of natural resources companies also pose similar challenges. What if? Traditional valuation methods e. In the case of the natural resources company if its exploration is successful, then substantial profits will be generated and the company will be quite valuable; if not, again, it will be not so valuable; probably not even viable.

Empirical tests of the boundaries and tests comparing various option models are reviewed for options on a variety of underlying assets. The estimation problems most relevant to option pricing are also discussed.

There are Cablevision bonds, due inthat have been traded from toand the variance in ln monthly price s for these bonds is 0. The correlation between stock price and bond price changes has been 0. In most such investments, there is a cost associated with developing the resource, and the difference between the value of the asset extracted and the cost of the development is the profit to the owner of the resource.

Option pricing theory uses variables stock price, exercise price, volatility, interest rate, time to expiration to theoretically value an option. Essentially, it provides an estimation of an option's fair value which traders incorporate into their strategies to maximize profits. Some commonly used models to value options are Black-Scholesbinomial option pricingand Monte-Carlo simulation. Understanding Option Pricing Theory The primary goal of option pricing theory is to calculate the probability that an option will be exercised, or be in-the-money ITMat expiration. Underlying asset price stock priceexercise pricevolatilityinterest rateand time to expiration, which is the number of days between the calculation date and the option's exercise date, are commonly used variables that are input into mathematical models to derive an option's theoretical fair value.
