This article presents the results of applying statistical tests to verify the distribution of market returns on common stocks of four large Russian blue-chip companies. The conformity of the market return distribution to the normal law was assessed using the Pearson and Shapiro — Wilk tests. Returns over a monthly interval are characterized by a normal distribution. Among the statistical indicators of the companies studied, the data from PAO Tatneft proved to be the most significant.
