GTOS invests in a wide range of global fixed-income securities including corporate bonds, government debt, and mortgage- and asset-backed securities. In seeking total return, the fund may hold high-yield bonds up to 30% of the portfolio and non-USD-denominated debts capped at 20%. It aims to maintain a dollar-weighted average portfolio maturity and duration between 1-3 years to minimize volatility and sensitivity to interest rate changes.
