CORONEL-BRIZIO, H.F. e HERNANDEZ-MONTOYA, A.R.. Asymptotic behavior of the daily increment distribution of the IPC, the mexican stock market index. Rev. mex. fis. [online]. 2005, vol.51, n.1, pp.27-31. ISSN 0035-001X.
In this work, a statistical analysis of the distribution of daily fluctuations of the IPC, the Mexican Stock Market Index is presented. A sample of the IPC covering the 13-year period 04/19/1990 - 08/21/2003 was analyzed and the cumulative probability distribution of its daily logarithmic variations studied. Results show that the cumulative distribution function for extreme variations, can be described by a Pareto-Levy model with shape parameters α= 3.634 ± 0.272 and α= 3.540 ± 0.278 for its positive and negative tails, respectively. This result is consistent with previous studies, where it has been found that 2.5 < α < 4 for other financial markets worldwide.
