After making researches of world literature about the above - mentioned phenomenon, some hypothesis were revised. The linear regression of Jensen model was used for comparison the value of above the average rate of return on the only one ETF for WIG20 index which is traded on the Warsaw Stock Exchange with those received on the index. On its results it was concluded that ETF does not provide any positive excess returns over its benchmark. Lack of market timing skills was showed on the basis of model proposed by Treynor and Mazuy. Tracking errors estimate for ETF and WIG20 were presented with usage of three methods.
