Fidelity New Markets Income Fund 

The fund's primary strategy involves dedicating a minimum of 80% of its total assets to securities issued by entities in emerging market economies. These are specifically defined as countries possessing emerging stock markets (per MSCI's classification), nations categorized by the World Bank as having low- to middle-income economies, or other markets exhibiting similar developing characteristics. Furthermore, its investments extend to other holdings that share an economic connection with these global emerging markets. Notably, this fund is structured as a non-diversified portfolio.
