This paper investigates the performance of selected mutual funds in Poland.  Specifically we examine the performance of share mutual funds and bond mutual funds by determining the inices of Sharpe, Treynor and Jensen's Alpha for each fund and for the market index WIG for the period 2004-2007.  We also examine the coefficient of variation for each fund, by category and by year.  Our results indicated that both funds performed well in 2005.  However during the other years and in the whole period, the share funds exhibited better performance than the bond funds, since the latter had mostly negative values in the three performance indices.  The performance has decreased in 2007 for both funds.
