The purpose of this research is to analyze the impact that a sample of securities blended together would have upon the variance of the expected returns of an energy and a gold-minerals portfolio. A framework based on the Markowitz model, but solved linearly, has been constructed in which the optimal weight of each security in its respective portfolio is determined in order to minimize variance given the expected portfolio returns. The data elaborated for each stock (price, return and dividend) were on an annual basis for a period of 16 years and are the basis from which the projections of both the energy and the gold-minerals portfolio expected returns were derived. The results show that the variance in both portfolios is considerable, because stocks as a group show co-movement, meaning that stocks tend to do well or poorly as a group.
