Active Strategies, Randomness and Ability in Investment Fund’s Performance Evaluation: a Behavioral Approach

This paper follows one main purpose: approaching classical models from a behavioral point of view. And two secondary objectives: First, providing behaviorally based tools to study efficiency in investment funds markets. Second, proposing a new methodological approach in order to disentangle randomness from ability in investment fund’s performance.

We reach two main theoretical proposals:
To set the fourth order moment of our Sharpe’s ratio differences based indicator as a market efficiency measure.
To take the statistical comparison of the probability distribution of the fund’s Net selectivity with a N (0, σ p ) distribution, as an indicator of luck/skill in investment funds performance measurement.
In order to illustrate these proposals, we take a randomly chosen sample of investment funds investing in four sectors: energy, financial, industrial and technology. We analyze: First, the cross sectional level of activity/efficiency in the market. And second, whether the individual results of each fund are ability or randomness caused.
