For stock prices the return is randomly distributed normally and iid. The process for a stock price. Hence the stochastic process ϕtSt is the value of the portfolio ϕt at time t.

The stock price follows an Ito process with drift and diffusion terms dependent on the stock price and on time which we summarize in a single subscript. We must consider them as a collection of random variables Obviously the order is important - when you enter at time j and exit at time k you care about another random variable A collection of time indexed random variables - a stochastic process. The PE ratio or price-to-earnings ratio is the one of the most popular valuation measures used by stock market investors.

Stochastic processes are an interesting area of study and can be applied pretty everywhere a random variable is involved and need to be studied. April 20 1111AM EDT.

Using Ito formula it is straightforward to derive the below equation. This process models a stock price with time-dependent instantaneous mean rate of return αt and volatility σt. Stock Prices The original paper by Black and Scholes assumes that the price of the underlying asset is a stochastic process S t which is solves the following stochastic differential equation in the differential form.

St is the vector of security prices at time t. A stock price is currently at 40 At the end of 1 year it is considered that it will have a normal probability distribution of with mean 40 and standard deviation 10 8. 5500 000 000 At close.
