Alpha manager ratings services is a quantitative-based tool that takes into account performance through all market conditions. It covers risk-adjusted alpha, consistency of performance versus a benchmark and consistency of a manager’s performance in rising and falling markets.
Manager data on Trustnet goes back to 2000 but anyone with a three-year track record can be an alpha manager.
The ratings are rebalanced once a year in a bid to counteract periods were managers have poor months or poor quarters. Any period where there is no record of performance is treated as a flat period.
