    Over a long period of time, there has been a rich debate in the academic and financial world if active management can generate an excess return. Many experts say that the current active management strategies is nothing more than a money grab that produces large gains, for banks and investment firms, through high management fees while producing no excess value for the individuals buying their service. In short, an effective market makes it almost impossible for fund managers to produce value for their clients in the long run.

    No argument has only one side though, other experts say that active management has a role to play because not all investors are rational. This irrationality can lead to mispricing on financial assets in the marketplace and in turn lead to an ineffective market where active management can fill a much needed role. The purpose of this study is therefore to see if active management strategies can create a higher risk adjusted return, taking management fees into consideration, during times of high volatility when the uncertainty is at its peak. We studied the time period of 2003-2012 where 2008 was by far the most volatile year and in being so was the main focus point for our study.

    In trying to make as strong a case as possible we gathered 250 mutual funds continuous daily data of ten years for volatility and yield. We had trouble getting a reliable and valid result using the Sharpe ratio and the modified Sharpe ratio when we studied 2008, we used the Sharpe ratio for the ten year study but we had to use a two dimensional measurement for 2008 which focused exclusively on volatility and yield.

    The result of the study states that during 2008 we could not show a statistical significance in favor of active management in terms of excess returns when we used the Sharpe ratios. We could however observe if we looked at the frequency data, regarding volatility and yields, see that active management created a higher value for its clients than passive management during 2008. When we observed the results for the whole time period we saw that active management created a significant positive difference in yield toward passive management. The conclusion of the study is therefore that active management can generate an excess value for its investors not just in times of distress but in all market climates.
