As a sample we use equity and hybrid funds investing on the local financial market. We calculate the annual unadjusted raw returns as well as risk adjusted returns from a single - index model and then create two portfolios: first, including all the funds which existed at the beginning of 1999 and second, consisting only of the funds which survived until 2004. The estimates are the differences in the returns between those two portfolios. We find that survivorship bias (ranging up to 30 basis points) so far is not essential for the performance of Polish mutual funds.
