Private equity is one of the most powerful; and most controversial — forces in modern finance. PE firms control companies employing millions of people, manage trillions in assets, and generate returns that have historically outperformed public markets. They also load companies with debt, cut thousands of jobs, and extract fees that would make a hedge fund blush. Understanding private equity means understanding both sides of this coin.
At its simplest, private equity is the business of buying companies that aren't publicly traded on stock exchanges; or taking public companies private by buying all their outstanding shares. The word "private" refers to the ownership structure: these companies don't have publicly traded stock.
A PE firm raises a pool of capital from investors, uses that capital (plus a significant amount of borrowed money) to acquire companies, works to increase those companies' value over several years, and then sells them for a profit. The profit is split between the PE firm and its investors according to a predetermined structure.
Think of it as house flipping, but for entire companies. Buy a company that's underperforming or undervalued, renovate it (improve operations, cut costs, grow revenue), and sell it for more than you paid. The scale is different; we're talking about deals worth billions; but the concept is the same.
The leveraged buyout (LBO) is the most common type of PE deal and the one that defines the industry. Here's how it works:
The leverage is what makes PE returns so attractive (and so risky). If you buy something with 60% borrowed money and the value goes up 80%, your equity return is far higher than 80%. But if the value drops and the company can't service its debt, it can go bankrupt — and the PE firm's equity can go to zero.
PE firms operate through a specific legal and financial structure:
Private equity (PE) involves firms that raise capital from institutional investors and high-net-worth individuals to buy companies, improve their operations, and sell them for a profit — typically within 3-7 years. PE firms often use significant debt (leverage) to finance acquisitions, amplifying returns.
PE firms earn management fees (typically 2% of committed capital annually) and carried interest (typically 20% of profits above a hurdle rate). The real money is in carried interest — if a fund returns 3x on a $1 billion fund, the 20% carry on $2 billion in profits is $400 million for the general partners.
Traditional PE funds require $250K-$25M minimums and accredited investor status. However, newer options provide access: publicly traded PE firms (Blackstone, KKR, Apollo), interval funds with lower minimums ($25K), and some platforms offering PE exposure to accredited investors for $50K+. Returns aren't guaranteed to beat public markets after fees.

What Is a Hedge Fund? Strategies, Fees, and Access
Hedge funds are private investment funds that use complex strategies to generate returns. Here's how they work, the 2-and-20 fee structure.
The fee structure is the famous "2-and-20":
PE firms don't just buy companies and wait for them to appreciate. They actively work to increase value through several strategies:
A handful of firms dominate the PE landscape, and their names appear constantly in financial news:
Many of these firms are now publicly traded themselves (Blackstone, KKR, Apollo, Carlyle), which is ironic; firms that specialize in taking companies private have gone public to access more capital and provide liquidity to their founders.
The central claim of private equity is that it outperforms public stock markets over time. The data on this is real but nuanced:
This means manager selection is everything in PE. The difference between a great PE firm and a mediocre one is enormous — far larger than the difference between two stock-picking mutual funds. The problem for individual investors is that the best PE firms are usually oversubscribed and have their pick of LPs, making access difficult.
It's also worth noting that PE return calculations have been criticized. PE firms control when they mark their portfolio companies' values (since there's no public market price), which can smooth out volatility and make returns look better on a risk-adjusted basis than they might actually be.
One of PE's biggest drawbacks has always been illiquidity. When you commit capital to a PE fund, it's locked up for 10+ years. You can't sell your position on a stock exchange. But the secondary market for PE fund interests has grown dramatically, creating a partial solution.
In a secondary transaction, an existing LP sells their fund interest to another investor, often at a discount to the fund's stated net asset value (NAV). Buyers in the secondary market get access to more mature investments (past the risky early years) at potentially discounted prices. Sellers get liquidity they wouldn't otherwise have.
The PE secondary market has grown from virtually nothing two decades ago to over $100 billion in annual transaction volume. Firms like Lexington Partners, Ardian, and Coller Capital specialize in secondary transactions.
Historically, PE was exclusively for institutions and the ultra-wealthy. But several vehicles now provide some degree of retail access:

PE faces significant and often legitimate criticism. The major complaints:
Like all financial markets, PE operates in cycles. Low interest rates make leverage cheap, driving up deal activity and purchase prices. PE firms compete with each other and with strategic buyers, pushing valuations higher. Eventually, overpaying and over-leveraging lead to underperformance, funds disappoint LPs, and capital commitments slow down.
The 2020-2021 era was a PE boom — cheap debt, rising valuations, and abundant exit opportunities. The 2022-2023 period saw higher rates, fewer exits, and a significant slowdown in deal activity. This cyclicality means that the vintage year (when the fund was raised) matters enormously for PE returns.
Private equity is a major part of the financial landscape, whether you invest in it or not. PE firms own household-name companies, employ millions of people, and influence industries from healthcare to housing. Understanding how PE works helps you evaluate these companies as a consumer, employee, or investor.
If you're considering PE exposure, start by understanding the tradeoffs: potentially higher returns in exchange for illiquidity, high fees, and manager selection risk. For most individual investors, a diversified portfolio of low-cost index funds will outperform a random PE fund on a net-of-fees basis. But if you have a long time horizon, access to top-tier managers, and can tolerate illiquidity, PE can play a role in a diversified portfolio. Just go in with your eyes open about both the potential rewards and the very real costs.
