3Y tracking error

0.09%

A positive return gap means the fund finished ahead of the index over that window. The 3Y tracking error shows how variable that monthly gap was; lower means steadier tracking. MethodologyReturn gap and tracking errorReturn gap is the fund's return minus its index over the same months, converted to a yearly rate. Tracking error is the annualised standard deviation of those monthly fund-minus-index returns. Both lines come from the manager's own chart, in the same currency and the exact index variant the fund tracks. We use month-end values so different intraday valuation times are not mistaken for tracking error.. Not investment advice.
