Private Equity (PE)

Private equity is investment in the ownership of companies whose shares do not trade on a public exchange. In its most common form it is practiced by funds that raise money from institutions and wealthy individuals, use it to buy controlling stakes in established companies, work to increase each company's value over a holding period of several years, and then sell, returning the proceeds to investors. It is distinct from venture capital, which funds young startups, and from angel investing, where an individual backs the very earliest companies. Private equity generally targets mature businesses with existing revenue and cash flow.

A defining feature is the use of leverage in the classic "buyout": the fund finances an acquisition partly with borrowed money secured against the target company itself, which magnifies returns when things go well and losses when they do not.

A private equity fund is structured as a limited partnership with a fixed life, commonly around ten years. The manager, the general partner, raises a pool of committed capital from limited partners, then draws that capital down through capital calls as it finds and closes deals, rather than holding all the cash at once. This is why a limited partner must keep committed money available: a call can arrive with little notice. As portfolio companies are sold, usually through a sale to another company, a sale to another fund, or an initial public offering, proceeds are distributed back.

The economics produce a characteristic J-curve. In the early years, management fees and deal costs are paid while investments are still being built and are carried at or near cost, so reported returns are negative. Value shows up later as companies are improved and sold, so the return line dips before it climbs. Judging a fund on its first few years is therefore misleading by design.

Fees follow the private-fund standard of roughly "2 and 20." The general partner charges an annual management fee, historically about 2 percent of committed or invested capital, and takes carried interest, typically 20 percent of the fund's profits, usually only after limited partners receive their capital back plus a preferred return, or hurdle, often around 8 percent. Carried interest is taxed as long-term capital gain when the underlying gains qualify, a treatment that has been politically contested for years but remains in place.

Access has historically required accredited-investor or qualified-purchaser status and a large minimum commitment, which kept private equity institutional. That is changing at the edges: interval funds and other registered vehicles now offer retail investors limited, more liquid exposure, and a 2026 Department of Labor proposal would make it easier for 401(k) plans to include private equity inside professionally managed options. Those routes trade some of the illiquidity for additional fees and structure.

In a leveraged buyout, the fund identifies a target company, agrees a purchase price, and finances it with a mix of the fund's equity and debt borrowed against the company. The fund then works to raise the company's value: improving margins, growing revenue, paying down debt, or combining it with other businesses. After several years it sells, and the sale proceeds first repay the debt, with what remains flowing to the fund's investors.

A hypothetical example of how leverage magnifies the outcome. A fund buys a company for $100 million using $40 million of its own equity and $60 million of debt. Over five years the company's value rises to $150 million and the debt is paid down to $40 million. The equity is now worth $150 million minus $40 million, or $110 million, against the original $40 million invested, before fees. The same 50 percent rise in company value produced a far larger percentage gain on the equity, which is the buyout math. The same leverage works in reverse: had the company's value fallen to $70 million, the equity would be worth $70 million minus the remaining debt, a steep loss.

Pros

• Access to a large universe of established companies that never trade publicly, including firms that increasingly choose to stay private.
• Active ownership can genuinely improve a business in ways a passive public shareholder cannot.
• Historically strong returns for top-quartile funds, though the dispersion is wide.

Cons

• Illiquidity: capital is committed for roughly a decade with no reliable early exit.
• Leverage magnifies losses as well as gains and adds the risk that a portfolio company cannot service its debt.
• High "2 and 20" fees consume a large share of gross return, and the average fund's edge over cheap public equity after fees is contested.
• Enormous gap between the best and worst managers, so results depend heavily on manager selection and access to top funds.
