The aim of this article is to characterize the volatility of share prices of companies belonging to WIG20 and the WIG20 index itself using statistical methods. The share prices of the companies were subject to deep fluctuations in the selected time period. The correlation analysis shows a random nature of the changes. The analysis of the remaining indicators indicates sector connections of companies, i.e. share prices of companies with a similar profile are correlated with one other. The applied method of backward stepwise regression allowed to build a model to predict changes in the WIG20 index with 70% certainty.
