Fund Metrics

GET/v2/funds/metrics

Returns all metrics for a fund in a single paginated response, with the latest observation per metric name.

Metric groups:

NAV: latest net asset value per share in the quoted currency
AUM: total fund assets under management, aggregated across all share classes of the fund
Cumulative returns: YTD, 1M, 3M, 6M, 1Y, 3Y, 5Y, 10Y and since inception, in percent
Annualized returns: 3Y, 5Y, 10Y and since inception, in percent
Calendar year returns: calendar_year_return_YYYY, in percent
Risk and cost metrics: volatility, Sharpe ratio, beta, alpha, information ratio, tracking error, max drawdown, TER, ongoing charges and SRI

Coverage varies by metric and fund. NAV and AUM cover most of the fund universe. Performance returns are backfilled progressively and may be unavailable for individual funds. The date field of each item states the observation date of that value.

Use fields to select specific metrics by metricId or metricName. The endpoint /v2/funds/metrics/names returns all valid metric names.
