ETF · Currency in USD · Last updated Jun 3, 2026

United States Copper Index Fund tracks the SummerHaven Copper Index Total Return, providing exposure to copper futures contracts on the COMEX exchange. The index selects one or three copper futures contracts monthly based on quantitative formulas relating to the shape of the copper futures curve.

CPER's Sharpe Ratio of 0.99 indicates that for each unit of volatility, it generates 0.99 units of excess return above the risk-free rate. The ratio is calculated using historical daily returns over the past 12 months (as of Jun 3, 2026).

Sharpe uses total volatility (standard deviation) which includes both upside and downside price movements, making it useful for comparing risk-adjusted returns across different assets.
