A study
was conducted by Arugaslan, Ed and Ajay (2007) to evaluate the risk-adjusted
performance of US mutual funds. Study employed a sample of 20 largest US-based
mutual funds for the period 1995-2004. Study used Quarterly returns for
computing the measures of return and risk. Modigliani and Modigliani (M Square)
and Sortino Ratio are used to evaluate the performance. Study identified the
performance evaluation over a five-year (2000-2004) and ten-year (1995-2004)
investment horizon. The authors concluded that funds with the highest returns
faced higher risk due to which funds lose attractiveness.
