Pension plans, endowments and wealthy families often hold all three: mutual funds, hedge funds and private equity funds. Each is a way of pooling money under a professional manager. But the three are built very differently, and those differences decide how often investors can get their money back, what the manager may do, how much investors see and how the fund is regulated.
For anyone working in operations or investor relations, these differences shape the daily work: how often the fund is valued, how redemptions are handled, and what reports investors receive. For allocators, they decide where each fund fits in a portfolio. This lesson compares the three side by side.
Three kinds of pooled fund
All three types take money from many investors, pool it, and pay a manager to invest it. Here is a quick sketch of each.
- A mutual fund is a fund offered to the general public. In the US, mutual funds are registered with the securities regulator and follow detailed rules on what they may invest in, how much they may borrow and what they must disclose. Most invest in listed shares and bonds. Investors can typically buy or sell on any business day. Many other countries have similar public funds under different names.
- A hedge fund, as Lesson 1.1 explained, is a privately offered fund with a flexible mandate. It can short, use leverage and derivatives, and trade many asset classes. It is offered only to eligible investors.
- A private equity fund, covered in PE101, is a privately offered fund that buys stakes in unlisted companies, improves them over several years and then sells them. Investors commit capital for the fund's whole life, commonly about ten years.
Hedge funds and private equity funds share a lot. Both are offered privately. Both are commonly set up as limited partnerships, with a general partner (GP) that controls the fund and limited partners (LPs) that provide the capital but do not run it. Both commonly charge a management fee plus a share of profits. The big difference between them is liquidity, which comes from the kinds of assets they hold.
A side-by-side comparison
The table below shows typical features. Real funds vary, and there are exceptions in every column.
| Feature | Mutual fund | Hedge fund | Private equity fund |
|---|---|---|---|
| Investors | The general public, often with low minimums | Eligible investors: institutions and wealthy individuals | Mostly institutions, plus wealthy individuals and family offices |
| Liquidity | Commonly daily | Commonly monthly or quarterly, with notice; sometimes a lock-up | Locked up for years; money returned as investments are sold |
| Structure | Open-ended | Open-ended | Closed-end |
| Strategy flexibility | Limited by a stated objective and by rules on leverage, shorting and concentration | Broad: shorting, leverage, derivatives, many asset classes | Focused: buying and improving private companies, often with debt at the company level |
| Fees | A management fee, usually with no performance fee | A management fee plus a performance fee on gains | A management fee plus carried interest, usually after a minimum return to investors |
| Valuation | Every business day | Commonly monthly | Commonly quarterly |
| Transparency | Regular public reports of holdings and results | Reports to the fund's own investors; detail varies by manager | Detailed quarterly reports to the fund's own investors |
| Regulation | Registered and closely regulated as public funds | Privately offered; the manager is commonly registered and reports to the regulator | Privately offered; the manager is commonly registered and reports to the regulator |
The rest of the lesson looks at the rows that matter most.
Liquidity: open-ended vs. closed-end
Liquidity is how quickly and easily an investment can be turned into cash. For a fund investor, it means how soon you can get your money back.
An open-ended fund keeps accepting new money and paying out redemptions on a regular schedule. Investors buy in (a subscription) and cash out (a redemption) at the fund's net asset value (NAV), the value of its assets minus its liabilities, divided among its units or shares. Mutual funds and hedge funds are both open-ended. The difference is how often they deal.
- A mutual fund commonly deals every business day. An investor who asks to sell today is usually paid within a few days.
- A hedge fund commonly deals monthly or quarterly. Investors must usually give a notice period, telling the fund in advance, often by weeks or months, that they want to redeem. Some funds also have a lock-up, a period after investing during which the investor cannot redeem, or can only redeem by paying a fee.
A closed-end fund raises money once and does not let investors withdraw on demand. A private equity fund is the standard example, as PE101 Lesson 2.1 explains. Investors make a capital commitment, the manager calls that money over several years, and the investors get money back only as companies are sold.
Why do hedge funds sit in the middle? It comes down to what they own and how they trade. A hedge fund may hold concentrated or leveraged positions, or assets that take time to sell. If investors could withdraw daily, a wave of redemptions could force the manager to sell at bad prices, hurting the investors who stay. Less frequent dealing, notice periods and lock-ups give the manager time to raise cash in an orderly way. Many hedge funds can also impose a gate, a limit on how much can be redeemed on one dealing date. Lesson 4.1 covers these terms in detail.
Private equity takes this logic further. Its assets are whole private companies, which can take months to sell. Daily or even quarterly redemptions would not work, so investors commit for the life of the fund.
Flexibility, fees, transparency and regulation
These four rows are linked. Funds sold to the public get more protection and less freedom. Funds sold privately to eligible investors get more freedom and less protection.
Strategy flexibility. A US mutual fund must follow the investment objective in its offering documents and the rules that apply to public funds, including limits on borrowing and on some uses of derivatives and short sales. A hedge fund's limits come mainly from its own offering documents, which are often broad. That freedom is what allows the Kessling Harbor Equity Long/Short Fund to sell short and use leverage. A private equity fund has a focused strategy set out in its partnership agreement, but within that, it takes control of companies, which neither of the others usually does.
Fees. Mutual funds usually charge only a management fee and other running costs, expressed as a percentage of assets. They rarely charge a performance fee. Hedge funds commonly charge a management fee plus a performance fee, a share of gains, usually calculated each year on the fund's NAV, including gains not yet realized. Private equity funds charge a management fee plus carried interest, a share of profits usually paid only as investments are sold and after investors have received their capital and a minimum return. So both private fund types reward the manager for results, but the timing and mechanics differ. Hedge fund fees overall have come down over time, as Lesson 1.3 notes, and Lesson 3.3 works through the calculations.
Transparency. A mutual fund publishes regular reports and lists its holdings, and anyone can see its price every day. A hedge fund reports mainly to its own investors, commonly through a monthly statement and letter. Many managers limit how much position-level detail they share, to protect their trading ideas, especially short positions. Large investors often negotiate more detail. Private equity funds give their LPs detailed quarterly reports on each company they own.
Regulation. Mutual funds themselves are registered and closely regulated. Hedge funds and private equity funds rely on being offered privately, so the funds face fewer rules. But in the US, many of their managers must register with the securities regulator as investment advisers and file regular reports. The rules are applied mainly to the manager rather than to the fund. Lesson 1.3 explains how this came about.
Where the lines blur
The three categories are useful, but the borders are not sharp.
- Some public funds follow hedge fund-style strategies, such as long/short equity, within the limits of public fund rules and with daily dealing. They are often marketed as "liquid alternatives".
- Some hedge funds hold hard-to-sell assets, such as distressed debt or private loans, and use longer lock-ups and less frequent dealing. They can start to look like private equity or private credit funds.
- Some private equity managers now offer evergreen funds, which have no fixed end date and allow periodic subscriptions and limited redemptions.
When you meet a new fund, do not rely on its label. Read its terms: who can invest, how often it deals, what it can invest in and how the manager is paid.

Key takeaways
- Mutual funds, hedge funds and private equity funds all pool investors' money, but differ in who can invest, liquidity, flexibility, fees, transparency and regulation.
- Mutual funds commonly deal daily; hedge funds are open-ended but commonly deal monthly or quarterly with notice periods and sometimes lock-ups; private equity funds are closed-end.
- Public funds get more protection and less freedom; privately offered funds get more freedom and less protection.
- Hedge funds and private equity funds both commonly charge a management fee plus a share of profits, but the timing and mechanics differ.
- Labels can mislead, so always read a fund's terms.
