Portafolios de inversión mexicanos: sustentable vs tradicional.

The objective of this paper is to compare the investment portfolios made up of assets from the traditional Mexican index S&P/BMV IPC versus the sustainable index S&P/BMV Total México ESG Index in the COVID-19 period. The results of this research, through empirical evidence, show that traditional investment portfolios are better than the sustainable in terms of the returns obtained in the study period; the methodology of three different types of investment portfolios is considered: 1. Equiweighted (arithmetic average), 2. Minimum Markowitz Variance (minimization of the variance and therefore of the risk of the portfolio, which is the standard deviation) and 3. Maximum Sharpe (maximization of the Sharpe index, an index that determines assets with returns higher than those of the reference rate). The main limitation is that normally distributed returns are assumed. The originality of the work is that a comparison is made between the traditional and sustainable Mexican index in a period of health crisis. It is concluded that the portfolios analyzed in a traditional way are better than the sustainable, for the three types of portfolios analyzed, the returns obtained were always higher.
