What Is Private Equity?

By James Kwak

Recently, a lot of the political debate has been about whether private equity—and by extension Mitt Romney—is good or bad. The argument on one side is that private equity firms are vultures who destroy firms to make money; on the other, that private equity is just capitalism at work, creates value, and creates jobs.

A private equity firm is an asset management company. It creates investment funds that raise most of their money from outside investors (pension funds, insurance companies, rich people, etc.), and then manages those funds. As opposed to a mutual fund, however, instead of buying individual stocks, these funds usually make large investments either in private companies or in public companies that they “take private” (more on that in a minute). While mutual funds and most hedge funds try to make money by guessing where securities prices will go in the future, private equity funds try to make money by taking control of companies and actively managing them. (There is a bit of a spectrum here, since mutual funds and hedge funds can exercise pressure on company management and private equity funds do take minority positions, but that’s the ideal-typical distinction.)
