The Kaplan-Meier estimator was used in the analysis of the probability of increase and decrease of prices of shares in the macrosectors. The intensity of decrease and increase of prices was assessed by means of the empirical hazard model and the proportional Cox model. Threshold values of the increase and decrease of prices were calculated on the basis of changes of the WIG index in analysed periods. Comparative analysis of these two periods was also conducted.
