The report I'd love to see is one that determines whether there are any unusual characteristics among outperforming fund managers that cannot be explained by chance. For example, I'd love to see: the percent of fund managers who quote Warren Buffett that outperform over five- and 10-year periods; the percent of fund managers who are significant investors in their own funds that outperform the indices over five- and 10-year periods; and so on.
