The State Street DoubleLine Short Duration Total Return Tactical ETF is an actively managed fund designed to maximize current income. It targets short-duration fixed income, maintaining a dollar-weighted average effective duration between one and three years. The ETF's strategy involves combining both traditional and non-traditional fixed income asset classes, employing active sector allocation and careful security selection to achieve its income objective. Furthermore, the fund seeks to outperform its benchmark by identifying and capitalizing on undervalued opportunities within the bond market, including investments in asset classes not typically covered by the index, such as high yield bonds and emerging markets debt.
