Survivorship Bias
Many funds might liquidate or merge during a period of study. This usually occurs due to continued
poor performance by the fund. Therefore, if index returns were compared to fund returns using only
surviving funds, the comparison would be biased in favor of the fund category. These reports remove
this bias by (a) using the entire investment opportunity set, made up of all funds in that particular
category at the outset of the period, as the denominator for outperformance calculations, (b) explicitly
showing the survivorship rate in each category, and (c) constructing peer average return series for each
category based on all available funds at the outset of the period.
