The Fidelity Global High Income Fund primarily seeks to generate returns by investing in a diverse array of income-generating instruments, including various debt securities, preferred shares, and convertible bonds. A significant portion of its portfolio is dedicated to lower-rated, higher-yielding debt issued by entities in both the United States and international markets, encompassing developing nations. Beyond these core holdings, the fund also maintains the flexibility to opportunistically invest in non-income producing assets, such as defaulted securities or ordinary common stocks.
