For many of us, it is literally a one way conversation with Greco Roman symbols. Here, we will derive formulas for European style Asian call and put options when we are taking geometric average of the underlying's price. We will put expectation and variance of the geometric average into Black's formula (generalized version), and will simplify it to obtain option formulas. And, the continuously sampled geometric average.The Black Scholes Model, also known as the Black-Scholes-Merton method, is a mathematical model for pricing option contracts. It works by estimating the variation in financial instruments. The technique relies on the assumption that prices follow a lognormal distribution. Based on this, it derives the value of an option.In the following, I will give a brief overview of the derivation of the Black-Scholes formula for pricing of European options, following the argument given by Black and Scholes (1973). This content is largely new to me, and I chose to read this paper because it seemed like a good idea to be familiar, at some level, with such an important model.CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract. Methods of proving the Black–Scholes formula for the price of an European call option fall into two categories: the bond replication method (the original one by Black and Scholes), and the call replication method (originated by Merton). if doing so would lead to a loss, S(T) K<0. The Black-Scholes formula for the price of the call option at date t= 0 prior to maturity is given by c(0) = S(0)N(d 1) e rTKN(d 2) where N(d) is the cumulative probability distribution for a variable that has a standard normal distribution with mean of zero and standard deviation ofoptions: call options and put options. Call and Put Options: Description and Payoff Diagrams A call option gives the buyer of the option the right to buy the underlying asset at a fixed price, called the strike or the exercise price, at any time prior to the expiration date of the option. The buyer pays a price for this right.Continuous-Time Models c 2009 by Martin Haugh Fall 2009 Black-Scholes and the Volatility Surface When we studied discrete-time models we used martingale pricing to derive the Black-Scholes formula for European options. It was clear, however, that we could also have used a replicating strategy argument to derive the formula.1While Black and Scholes consider the case of a long stock/short option trading strategy in their paper, a riskless portfolio can also obviously be created by dynamically hedging a short position in the underlying asset with a long position in a European call option. The Black-Scholes trading strategy synthetically replicatesratio. The derivation stipulates that in order to hedge the single option, we need to hold shares of the stock. This is the principle behind delta hedging. 1.1 Original Derivation by Black and Scholes In their paper, Black and Scholes [1] set up a portfolio that is slightly di⁄erent: it is comprised of one share and 1= shares of the option.Find Spot Price. Consider the case where the option price is changing, and you want to know how this affects the underlying stock price. This is a problem of finding S from the Black-Scholes formula given the known parameters K, σ, T, r, and C.. For example, after one month, the price of the same call option now trades at $15.04 with expiry time of two months.Now that we have the original Black-Scholes equation for an European option, we can make use of the results obtained in Section 3.2.2 to find the value of the option. Suppose the option considered is an European call option with price C(S, t). Therefore, equation (3.4.8) becomes C(S, t) = e−rf(T −t) C. 1(S, t) (3.4.11)The Black-Scholes Model M = (B,S) Assumptions of the Black-Scholes market model M = (B,S): There are no arbitrage opportunities in the class of trading strategies. It is possible to borrow or lend any amount of cash at a constant interest rate r ≥ 0. The stock price dynamics are governed by a geometric Brownian motion.We derive the Black Scholes European option price formula. We then calculate the derivatives of the option price formula (both call and put) with respect to the Black-Scholes' inputs in order to derive formulae for the Delta, Gamma, Vega, Theta, and Rho. We also give the put call parity for the price and show that all of the Greeks satisfy the parity.Every university student taking a module on finance has seen the Black-Scholes-Merton option pricing formula. It is long, ugly, and confusing. It doesn't even give an intuition for pricing options.
