8: The Black-Scholes Model - University of Sydney

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.

Thus 2 : 3 = 2 x 2 : 3 x 2 = 4 : 6 = 4 6: 2 2 = 2 : 3 If a = b, the ratio a : b is known as ratio of equality. If a > b, then ratio a : b is known as ratio of greater inequality i.e. 7 : 4 And for a < b, ratio a : b will be the ratio of Lesser inequality i.e. 4 : 7.
