The risk value of stocks acts as an indicator in selecting stocks to be included in a portfolio. Risk value of stock portfolios is used in selecting stock portfolio that follows investors' risk preference. This study forecast share price by using Geometric Brownian Motion and hence use the Variance Covariance to calculate Value at Risk of each stock and stock portfolio in future investment. The stock portfolios in this study are based on five sectors which are industrial-product, consumer, construction, technology, and trading and services. Thus, there are five stock portfolios that are produced for each type; Risk Averse and Risk Premium investors. Using the Value at risk of each stock portfolio, it is found that Stock portfolio from the Industrial Product Trading and Service sectors is the most suitable for Risk Averse and Risk Premium investors respectively.
