ETF Metrics

get

https://api.bavest.co/v2/etfs/metrics

Returns a paginated list of all ETF metrics — performance, risk, volatility,
and fund characteristics — with full lineage/traceability.

Metric groups:

Returns: 1M, 3M, YTD, 1Y, 3Y, 5Y, 10Y; annualized 5Y; since inception
(cumulative and annualized)
Risk (security & category): beta, alpha, sharpe ratio, treynor ratio,
R-squared, standard deviation, mean annual return (1Y/3Y/5Y/10Y)
Volatility: YTD, 1Y, 3Y, 5Y, 10Y
Risk indicators: SRI (price-based, 1-7), SRRI (document-based, 1-7)
Fund: tracking error, net management fee
Dividends: dividend_yield (trailing 12-month distributions / latest close,
percent; 0.0 for accumulating share classes)

Pass trace=true to include computation lineage (formula, inputs, explanation)
for each metric.

Check each metric's date for freshness. latestDate is the newest date across metrics and does not mean every metric (including AUM) is current.
