The population of high-net-worth-individuals (HNWIs) in Ghana is projected to increase from 2,400 in 2015 to 4,900 by 2024. HNWIs in Ghana desire to have access to alternative investment instruments to enhance diversification and improve investment returns on their portfolios. Guided by the product-market-grid-model, the purpose of this qualitative multiple case study was to explore diversification strategies some fund managers use to improve returns for HNWIs. Twelve participants from 3 investment firms in the Greater Accra Region of Ghana, including CEOs and fund managers with more than 5 years of professional and industry experience, participated in semistructured interviews. Observations and company documents served as secondary sources of data collection. Five themes emerged from the analysis of interview and document data: investment objectives and risk appetite level, product availability, asset allocation, limited knowledge and lack of sophistication, and, performance benchmarking. Findings may be used by fund managers to combine knowledge and innovation in identifying alternative investment options for HNWIs and improving investment returns. HNWIs may use their disposable income from returns to engage in entrepreneurial activities that may create employment opportunities and improve the economic environment in Ghana.
