The CAMRADATA Independent Quantitative (IQ) scores is a ranking reflecting five statistical factors measured over a three year period. Each factor generates a statistic which is shown as a percentage or a number in the table.
To rank products, the percentile ranking of each factor is determined and an overall master score is calculated. This is a simple average of all percentile rankings for each product across all five factors. Investment products which share the same value for a factor are assigned the same percentile rank within that factor.
The highest scoring products appear at the top of the table. For presentational purposes, we apply a 'unique sort' to pick out only the best product for each manager.
