State Street SPDR Portfolio Treasury ETF (SPTB) Sharpe Ratio: 0.93

ETF · Currency in USD · Last updated Jun 23, 2026

The SPDR® Portfolio Treasury ETF seeks to provide investment results that, before fees and expenses, correspond generally to the price and yield performance of the Bloomberg U.S. Treasury Index, offering low-cost exposure to U.S. Treasuries with remaining maturities of one year or greater.

SPTB's Sharpe Ratio of 0.93 indicates that for each unit of volatility, it generates 0.93 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 23, 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. For how to read this number and when it can mislead, see Sharpe Ratio Explained.
