Institutional investor

Institutional investor is a term for entities which pool money to purchase securities, real property, and other investment assets or originate loans. Institutional investors include banks, insurance companies, pensions, hedge funds, REITs, investment advisors, endowments, and mutual funds. Operating companies which invest excess capital in these types of assets may also be included in the term. Activist institutional investors may also influence corporate governance by exercising voting rights in their investments.

Roman law ignored the concept of juristic person, yet at the time the practice of private evergetism (which dates to, at least, the 4th century BC in Greece) sometimes led to the creation of revenues-producing capital which may be interpreted as an early form of charitable institution. In some African colonies in particular, part of the city's entertainment was financed by the revenue generated by shops and baking-ovens originally offered by a wealthy benefactor. In the South of Gaul, aqueducts were sometimes financed in a similar fashion.

The legal principle of juristic person might have appeared with the rise of monasteries in the early centuries of Christianity. The concept then might have been adopted by the emerging Islamic law. The waqf (charitable institution) became a cornerstone of the financing of education, waterworks, welfare and even the construction of monuments. Alongside some Christian monasteries the waqfs created in the 10th century AD are amongst the longest standing charities in the world (see for instance the Imam Reza shrine).
