Investment Companies: Structure, Types, and Key Points
What is an investment company?
An investment company is a pooled-asset vehicle—organized as a corporation, trust, partnership, or LLC—that invests investors’ collective capital in securities such as stocks, bonds, and commodities. Fund sponsors manage portfolios, provide record-keeping and custody, and offer investors a way to obtain diversification and professional management.
Regulation
In the U.S., most public investment companies register with and are regulated by the Securities and Exchange Commission under the Securities Act of 1933 and the Investment Company Act of 1940. Private funds (for example, many hedge funds and private equity funds) are often exempt from those registration rules but remain subject to other securities laws and regulations.

Main types of investment companies
- Closed-end funds
- Issue a fixed number of shares that trade on exchanges.
- Share price is set by market demand and may trade at a premium or discount to the fund’s net asset value (NAV).
-
Shares are bought and sold on the secondary market and are generally not redeemable with the fund.
-
Open-end funds (mutual funds)
- Continuously issue and redeem shares; the number of outstanding shares “floats” with investor flows.
- Shares are redeemable each trading day at the fund’s NAV.
- Typically invest in liquid assets so they can meet redemptions.
-
Common fee types include management fees and 12b-1 fees.
-
Unit investment trusts (UITs)
- Sell fixed units representing a specified portfolio of securities.
- The portfolio is typically fixed and not actively managed; the trust terminates on a predetermined date and distributes assets pro rata.
- May charge creation, trustee, and other fees.
How these companies operate
Investment companies pool investor capital, allocate it according to a stated strategy, and share profits and losses proportionally among investors. They provide portfolio management, custody, accounting, and reporting services. Fees and operating expenses are taken from the fund’s assets and therefore reduce investor returns; reading a fund’s prospectus is essential to understand costs and strategy.
Key concepts
- Net Asset Value (NAV): total value of a fund’s assets minus liabilities divided by outstanding shares. Used to price open-end fund redemptions; closed-end funds can trade at NAV discounts or premiums.
- Liquidity: open-end funds typically offer daily liquidity; closed-end fund liquidity depends on secondary market activity; UITs have limited liquidity until termination.
- Leverage: some funds use leverage to amplify returns, which also increases risk.
- Investor qualifications: private funds often limit participation to accredited or otherwise qualified investors.
Private investment funds
Hedge funds, private equity, and venture capital funds commonly operate as private investment vehicles that accept capital only from accredited or institutional investors. These funds are generally exempt from Investment Company Act registration but must comply with other securities rules and disclosure requirements.

Socially responsible investing and philanthropy
Some investment companies specialize in socially responsible investing (SRI) or environmental, social, and governance (ESG) strategies that screen for or prioritize companies with positive social or environmental impact. Donor-advised funds (DAFs) are another vehicle that lets donors contribute assets for charitable purposes while retaining advisory input on investments and distributions.
Brief history
The modern mutual fund era began in the early 20th century; one early example is the Massachusetts Investors Trust, established in 1924 as an open-end mutual fund designed to give small investors access to diversified stock portfolios.

What to evaluate before investing
- Fund objective and strategy: does it match your goals and risk tolerance?
- Fees and expense ratios: management fees, 12b-1 fees, and other charges.
- Liquidity needs: how and when you can redeem or sell shares.
- Performance and track record: compare to appropriate benchmarks and peers.
- Prospectus and disclosures: holdings, risks, and fee structure.
Conclusion
Investment companies offer a practical way to access professional management and diversification across many asset types. Understanding the differences among closed-end funds, open-end (mutual) funds, and UITs—along with fees, liquidity, and regulatory status—helps investors choose suitable vehicles and assess tradeoffs between return potential and risk.
