Black-Scholes and Binomial Models
There are different variables that usually impact the pricing options. This paper will be based on the attributes of the two widely accepted models that are used for pricing options; Black-Scholes and the Binomial Models. These two models are based on the same theoretical assumptions and foundations like risk neutral valuation and geometric price Brownian motion theory of stock price behavior.
Option pricing theory has become among the most powerful tools in commerce and finance. The famous Black-Scholes equation is an effective model that is used for option pricing. It was named after those who pioneered it; Black, Scholes and Merton who brought it up in 1973 and won a Nobel Prize economics in 19097 for discovering it. When we look at it mathematically we can say that it is a final value problem for a second order parabolic equation. In this case an option is a contract which gives the owner the right and not duty to purchase (call option) or sell (put option) an asset which in most cases is stock or parcel of...
Capital Asset Pricing Model and Arbitrage Pricing Theory: Capital Asset Pricing Model (CAPM) is an arithmetical theory that describes the relationship between risk and return in a balanced market. The Capital Assets Pricing Model was autonomously and simultaneously developed by William Sharpe, Jan Mossin, and John Litner. The researches of these founders were published in three different and highly respected journal articles between 1964 and 1966. Since its inception, the model
Finance There are three different models that can be used to estimate a company's cost of capital. Basically, each of these three is used to estimate the cost of equity. The cost of debt is usually calculated on the basis of the current weighted average of the yield to maturity on the company's debt. Thus, it is the cost of equity that must be calculated. The cost of equity reflects the
Black-Scholes Option Pricing Model was developed in the 1970s as a way to generate a legitimate and accurate valuation model for stock prices based on specific circumstances in the market and the stock options. It is the creation of economists Myron Scholes and Fischer Black who aimed to better forecast call options at various times within the option life cycle (PBS, 2000). According to the research, "this work involved calculating
The CAPM is useful to investors from two standpoints -- time value of money and the risk associated with the money invested. The time value of money is revealed by the free rate risk and represents the compensation investors will receive for having invested their money in the respective share, for a specific period of time. The risk of the investment is revealed by the second part of the
Finance Assessing WalMart Cost of Equity Cost of Equity Using CAPM To calculate the cost of equity using the capital asset pricing model (CAPM), the equation requires collection of some data regarding the firm and the market. The equation tells us what data is needed, the equation is cost of equity = RF + ?(RM - RF). RF is the risk free rate, RM is the return on a market portfolio, and ?
Capital Asset Pricing Model (CAPM) Basically, a diversifiable risk can be taken to be that risk which is largely limited to a given sector or security. On the other hand, a risk which affects the entire assets or liabilities class is referred to as an un-diversifiable risk. While it is possible to eliminate or reduce a diversifiable risk through diversification, the same cannot be utilized when it comes to the elimination
