STXT aims for maximum returns by investing in a diverse portfolio of debt securities, with a focus on residential and commercial mortgage-related securities, and mortgage loans. The fund has the flexibility to invest in bonds of any quality, maturity or origin, though foreign investments will typically be denominated in US dollars. The fund allocates up to 30% of its assets to high-yield securities and up to 15% to less liquid investments. On average, the portfolio duration aims to vary between two and nine years. Advisers for the fund utilize fundamental research and individual security analysis. Investment decisions are based on factors such as fiscal conditions, market liquidity, geopolitical risks, and collateral quality. The strategy aims to minimize the risk to the investor principal by focusing on underpriced assets.
