|SPDR Russell 2000 Low Volatility ETF|
|The investment seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of a small cap, low volatility index.
The fund employs a sampling strategy, which means that the fund is not required to purchase all of the securities represented in the index. Under normal market conditions, the fund generally invests substantially all, but at least 80%, of its total assets in the securities comprising the index. The index includes small cap U.S. equity securities and is designed to deliver exposure to low volatility. It is non-diversified.|
