In the context of performance evaluation, why might a manager need 20 to 30 years of data to statistically prove their 'skill' at the 95% confidence level?

  1. Regulatory requirements mandate a 30-year track record before a manager can be designated as 'skilled'.
  2. Market cycles typically last 30 years, and a manager must prove they can perform across a full cycle.
  3. The annual standard deviation of excess returns (tracking error) is very high relative to the typical magnitude of annual alpha.
  4. The multiple comparisons problem forces the significance threshold to become stricter over time.
