Hedge Funds Trade, Private Equity Buys Companies, and a Pension Is the Customer

In the usual U.S. setup, the fund has two seats. The general partner (GP) is the manager: the firm that picks trades or buys companies, hires staff, and lives with the results. The limited partner (LP) is the customer who promised the money and then mostly sits still — an endowment, a family office, an insurer, a wealthy person, or a pension trust that signed up for the fund. The restaurant version: the GP cooks; the LP paid to build the kitchen and reserved the table.

"Limited" is doing real work. An LP can lose what they promised to that fund. They typically do not owe the restaurant their house if the kitchen fails. The GP runs the operation and takes the reputation hit if the food is bad.

A giant public plan like CalPERS, a large union plan, and a university endowment are different organizations with different boards. When they put money into the same private equity or hedge fund, they occupy the same chair: customer (LP). They are not LPs when they simply hold listed stocks and bonds — that is ordinary investing, not signing up for a private fund. And the electrician or teacher whose dues or paycheck funded the plan is never that chair. They are a beneficiary. They receive a retirement check if the plan stays healthy. They do not pick the hedge fund.

GP and LP name the chairs. They do not name the job. A hedge fund and a private equity fund can share the same legal wrapper — a partnership, a management fee, a slice of profits — and still spend the decade doing different work.

A hedge fund typically trades things that already have a price: stocks, bonds, currencies, derivatives. The classic extra tool is going short — borrowing something, selling it, and hoping to buy it back cheaper later. The name comes from pairing buys with shorts. It is not a promise that the fund is safer than the market.

Holdings are often securities you could sell on a screen. That is why hedge funds sometimes offer a path back to cash after a waiting period: a monthly or quarterly window, some notice, maybe a gate if too many customers head for the door at once. The fund still calculates a NAV on those dates so new money, withdrawals, and fees have a number. That is not a 4:00 p.m. mutual-fund price you can tap from a brokerage app.

Private equity (buyouts, in the usual headline sense) buys companies, or controlling stakes in companies, that are not sitting on the public stock exchange as the main event. The fund may use loan money at the company — a leveraged buyout — then try to change how the business runs, and sell or list it years later. The scoreboard is often IRR and a multiple of money in vs. money out, not a daily ticker. Operating conversations lean on metrics such as EBITDA.

You cannot send the manager a letter and get cash next week. The asset is a chain of clinics or a software firm, not a basket of listed shares. Selling your seat to someone else (a secondary) is a different, often discounted side door — not a mutual-fund undo button. A classic fund asks for a ten-year life, often with a couple of one-year extensions. Money does not all leave the customer's account on day one. You commit a total; the manager sends capital calls when it actually buys something — like a contractor draw on a house, not a one-shot checkout.

The manager does not work for free. Two pay streams show up in almost every pitch, even when the percentages have drifted.

The management fee is rent for showing up. Hedge funds have historically charged about 2% a year of the money in the fund. Private equity often charges about 2% a year of the money customers promised during the first years (often years 1–5). After that buying window ends, that fee usually steps down to a percentage of the money still sitting in companies as those companies are sold. It pays salaries, research, and the lights. It is not a law — big customers often negotiate less.

The bonus is called carry (carried interest). It is a cut of profits, not of the rent. The folklore number is 20% of gains.

In private equity, that bonus usually does not start on the first dollar of profit. The paperwork often runs in this order:

1. Customers get their original money back.
2. Customers get a minimum return first — classically around 8% a year. That minimum is the hurdle (also called a preferred return).
3. Then the manager gets the next profit checks until they have their 20% cut of the whole profit. That step is called GP catch-up. It exists because customers just took the first 8% alone.
4. After that, any leftover profit is split the usual way: 80 cents to customers, 20 cents to the manager.

Hedge funds usually skip that PE waterfall. Their extra bonus often waits behind a high-water mark instead: no second bonus until the fund has climbed back above its last peak. The manager is not paid twice for recovering the same hole.

"2 and 20" is a nickname for that rent-plus-bonus shape. It is not a law, and it is not universal. Treat it as folklore with a real idea underneath: the manager gets paid to operate, and then gets a cut if the customer actually makes money.

A mutual fund is built around daily cash-out. These funds are built around the opposite: the manager needs time with the money.

In private equity, the customer signs a commitment — a promise of up to $X. The manager calls pieces of that promise when a deal closes. Until then, the uncalled amount is still a legal obligation, like a construction budget you have not drawn yet. Trying to yank the whole promise because markets got noisy is not how the contract works.

In a hedge fund, a lockup is the period when withdrawals are off the table. After that, you may still only exit on certain dates, and a gate can slow the line if too many customers leave together. That is the paint-is-wet rule: the manager agreed to a strategy that breaks if everyone sprints for the door on the same Tuesday.

A pension is not a third flavor of hedge fund. It is a pool with a job: pay retirees. The common U.S. design here is a defined-benefit plan. The plan promises a paycheck in retirement (a formula, not a brokerage login). That is a different contract from a 401(k), where the worker owns an account and picks funds inside it.

Trustees and staff — often with consultants — decide how that pool is invested. A large slice still sits in public stocks and bonds, where the plan is just another big holder, not an LP. Another sleeve, labeled alternatives on the slide, can include private equity, hedge funds, private credit, real estate, and infrastructure. There the plan trust is shopping as a customer (or as a co-investor next to the manager). It is not competing as a product on the same shelf.

Many union pensions are not one company's plan. They cover workers at many employers in the same trade — construction, trucking, groceries — so an electrician can move from contractor to contractor and stay in the same pension. The 1947 Taft-Hartley Act is why that structure is legal: employers can pay into a shared trust, but the board that runs it has to be split — half union trustees, half employer trustees. Neither side runs it alone. That jointly trusteed, multiemployer setup is the Taft-Hartley pattern. Public plans covering teachers, firefighters, or city workers sit in a sibling role, often with bigger checks. In both cases, when the trust puts money into a private equity or hedge fund, the trust is the LP on the papers. The member paying dues or contributing through payroll is a beneficiary of that trust, not an LP in the private fund. Not every local's plan writes those checks — size, how well funded the plan is, and how fast it needs cash all matter — but the large ones that do sit in the same customer chair as endowments.

University endowments and sovereign wealth funds sit in that same customer chair, usually with even longer horizons. They are not this chapter's thesis. They are proof that "who writes the check" is a role, not a brand name.

Retail here means a person buying through a brokerage app, with a prospectus and a sell button. The door is not closed because someone failed a personality test. It is closed because these private funds do not work like a mutual fund, and U.S. law treats a fund sold to the public more strictly.

An ordinary mutual fund you can buy in a brokerage account (an open-end fund under the Investment Company Act of 1940) has extra rules. It has to spread its bets, limit borrowed money, and usually let you cash out the same day. You cannot honestly promise daily cash-out if the money is locked inside a company for seven years. So classic private equity and hedge funds stay private. They do not sell to the public at large. They only take investors the rules treat as able to wait and able to lose the money. Other products under that same 1940 Act — closed-end funds, interval funds, and business development companies (BDCs) — are cousins. They are not the private partnership a pension signed.

A classic private equity or hedge fund stays private by using an exemption from those 1940 Act public-fund rules. Two exemptions show up over and over. They are different clubs. A third rule comes from a different law entirely. People mash all three together. The table is the un-mash.

Marketing blurbs flatten this into "you have to be rich." The forms ask three different questions. Mixing them is how explainers go wrong.

• Accredited investor is the Regulation D test: may a seller legally offer you the private deal?
• Qualified client is a different test: may a registered manager take a bonus cut of profits (not just a flat fee), often on smaller 3(c)(1) funds?
• Qualified purchaser is the 3(c)(7) test: may you own a piece of the big private fund?

Passing a test is a wristband. It is not a seat.

The same customer chair shows up in nearby products. Pensions write those checks too. Naming them keeps the map honest without turning this into an encyclopedia.

You are not locked out of every business that smells like private markets. The honest line is: you are usually not sitting in the pension's seat in the private fund the pension bought.

You can buy stock in a listed alternatives firm (the management company). You can buy shares of a listed business development company (BDC) — a registered vehicle that can lend to or take stakes in smaller companies, often with a ticker you can trade. Some interval funds are registered products that offer scheduled buybacks of a slice of shares, not daily cash-out. A few 401(k) target-date products now add a thin private-markets sleeve. Those are real products with their own fees, discounts, and cash-out rules. They are not the pension trust's seat in the private partnership, not the side-by-side co-invests, and not the fee break the giant check negotiated.

The screenshot below is a real Robinhood quote page for a listed BDC. The green Trade button is the sidewalk window: you can buy a ticker. That button does not sign you up for the manager's private fund.

Private equity sends cash in lumps, not a smooth line. That is why IRR shows up on every big-customer report — and why the True Annualized Return calculator is the public-markets cousin of that question. Everyday compounding still uses CAGR and the Compound Interest calculator. When someone is talking about a buyout company's operations, they still run through EBITDA. None of that replaces the seating chart. It is what the people in those chairs argue about after the money is already in.
