Definition: "Superendowment" is a concept in finance, particularly within the field of asset management. It refers to the accumulation of assets that are not directly related to their original purpose but rather serve as collateral for other financial instruments or investments. In the context of superendowment, it often involves an investment in a specific asset class that has historically provided high returns on its underlying value. This investment could be used as a basis for creating a diversified portfolio of assets, thereby potentially generating higher returns over time
