Money Laureate Myron Scholes developed the model of optional Black Scholes (together with Fisher Black). Describe the above model and explain the cases ???
The black schools model also known as black schools Merton model is considered to be the model of price variation. This model assumes that the price of heavily traded assets follow a geometric Brownian motion with constant drift & volatility. When applied to stock option, the model incorporates constant price variation of stock, time value of money, option’s strike price & time to option expiry.
This is considered to be one of the most important concepts of modern financial theory which was developed in 1973 by fisher black, Robert Merton & Myron scholes. This is considered to be best method for determining the price of options. It requires five important variables which include the strike price of an option, the current stock price, time to expiration, risk free rate & volatility. The model assumes that there are no transaction costs or taxes, risk free interest rate constant for all maturities, absence of riskless arbitrage opportunities etc.
Black-Scholes Formula
The Black Scholes call option formula is calculated by multiplying the stock price by the cumulative standard normal probability distribution function. Thereafter, the net present value (NPV) of the strike price multiplied by the cumulative standard normal distribution is subtracted from the resulting value of the previous calculation. In mathematical notation, C = S*N (d1) - Ke^ (-r*T)*N (d2). Conversely, the value of a put option could be calculated using the formula: P = Ke^ (-r*T)*N (-d2) - S*N (-d1). In both formulas, S is the stock price, K is the strike price, r is the risk-free interest rate and T is the time to maturity. The formula for d1 is: (ln(S/K) + (r + (annualized volatility) ^2 / 2)*T) / (annualized volatility * (T^ (0.5))). The formula for d2 is: d1 - (annualized volatility)*(T^ (0.5)).

How can i find more information about Black Schole model ( Nyron Scholes) . I Want more details about this model . More details about the cases and the describe.
Rewiew all the cases in detail (deep) of Black and Scholes Model (Formula) . A very deep discription of all assumptions of this formula.
Interpretation of the Black-Scholes model. What is the hedge ratio for a call (put) option and what is the probability that a call (put) option finishes in the money?
7. (10 pts) a In Black Scholes option pricing model explain what it means if N(d1 ) is 0.45 in terms of the movements in the stock and call option price. b. What is N(d1 ) referred to (what is the name) and what does it show? c. How many call options can you write on one share of stock if N(d1 ) is 0.5 in order to have a fully neutral hedged position?
Problem 2. You are given the following data assuming a Black-Scholes model. • S = $100 • 0 = 30% • p = 0.08 • S= 0 Suppose you sell a 95-strike put with 3 months to expiration. (i) (5 points) What is the gamma of this put option? (ii) (3 points) If the underlying were to decrease by $1 over the next short while, what effect would that have on this option's delta? (iii) (2 points) If all of...
Stable and Unstable Equilibria The black bear population model developed in the previous section is an example of a Leslie matrix. A Leslie matrix model of a population gives the rates at which individuals go from one life stage to another. In this case, we have two life stages, juvenile and adult. The diagonal entries give the fraction of the population that stays within the same life stage, while the off-diagonal entry in the top row gives the birth rate...
Describe each questions: Explain why the object-oriented database model was developed. How does the OID in the OO model differ from the primary key in the relational model? Is it possible for a superkey not to be a candidate key? Why or why not? Briefly describe the four types of binary relationships possible between an entity set A and an entity set B based on relationship cardinality. Sales Database: Customer(custId, lastName, firstName, address, phone, creditLimit) Order(orderNumber, date, total, custID) LineItem(orderNumber,...

CASE STUDY ARBITRAGE: IS THERE SUCH A THING AS A ‘FREE LUNCH’? With financial markets operating twenty-four hours a day, seven days a week throughout the world it is no surprise that there tend to be price discrepancies in the securities being traded. It is the manipulation of these discrepancies by a relatively small group of professionals that is referred to as arbitrage. Those who partake in this activity are called arbitrageurs. Arbitrage has existed in some form or another...
