I have 2 stocks in my portfolio A and B.A is currently at 50 dollars and B at 40 dollars. Correlation between A and B is 0. Let us say I bought the stocks today at 50 and 40 dollars. If I wish to use a Monte Carlo simulation to estimate the individual stock prices of my portfolio and the variance at the end of 1 year, what other info do I need?
If the mean of the stock A was 50, that of B was 40 , the SD of A was 5, that of B was 4(all measured over last 5 years), does that give me enough info to proceed? Do I just draw random prices from 2 log normal distributions(meanA=50,meanB=40,sigmaA=5,sigmaB=4) ,take the average of the prices and call it done?
What else do I need to consider for a basic simulation? This is for education, not profit.
