Analysis of Performance of the Warsaw Stock Exchange Companies from Finance Macrosector in Periods of Crisis

Abstract

The aim of the article is the assessment of response to a crisis situation for companies belonging to the macrosector of finance in comparison with other sectors on the Warsaw Stock Exchange. The survival analysis methods were applied. The authors analysed the periods of decrease and of the subsequent increase in share prices during the crisis of 2008–2009 and the bear market of 2011. The Kaplan–Meier estimator of the survival function made possible to assess the probability of decrease and of subsequent increase in the share prices. The similarity of the survival curves was investigated using the log-rank test. The Cox regression model was used to determine the intensity of the decrease and increase in share prices. The analysis made possible to assess and compare the performance of the financial sectors against the background of other sectors in both periods.
