Unit
- Definition: A mutual fund is a pooled investment vehicle that collects money from multiple investors and invests it in a diversified portfolio of securities such as stocks, bonds, or other assets. Each investor owns shares that represent a portion of the fund's holdings.
- Open-end vs. closed-end: Open-end funds issue and redeem shares continuously at net asset value (NAV), while closed-end funds have a fixed number of shares that trade on exchanges at market-determined prices. Most retail mutual funds are open-end.
- Net Asset Value (NAV): The per-share value of a mutual fund, calculated daily by dividing the total value of the fund's assets minus liabilities by the number of outstanding shares. NAV is the price at which investors buy and sell shares in open-end funds.
- Diversification: By pooling assets, mutual funds provide instant diversification across many securities, reducing unsystematic risk. A single fund may hold hundreds of individual positions, spreading exposure across sectors and geographies.
- Professional management: Funds are managed by professional portfolio managers who conduct research, select securities, and monitor performance. Management fees compensate these professionals and are disclosed in the fund's prospectus.
- Economies of scale: Large fund sizes allow for lower transaction costs per dollar invested, access to institutional pricing, and more efficient portfolio rebalancing. This benefits investors through lower expense ratios.
- Liquidity: Open-end funds offer daily liquidity, allowing investors to redeem shares at the next NAV. This contrasts with direct investments in individual securities that may be less liquid.
- Regulatory oversight: In the United States, mutual funds are regulated by the Securities and Exchange Commission (SEC) under the Investment Company Act of 1940. They must register, provide prospectuses, and adhere to strict disclosure requirements.
- Active vs. index funds: Actively managed funds rely on portfolio managers to pick securities in an attempt to outperform a benchmark, while index funds track a market index passively. Index funds typically have lower expense ratios because they require less research and trading activity.
- Load versus no-load funds: Load mutual funds charge a sales commission either at purchase (front-end load) or redemption (back-end load), which compensates brokers. No-load funds sell shares directly to investors without such commissions, reducing upfront costs and allowing more capital to be invested.
- Tax considerations: Mutual funds distribute capital gains and dividends to shareholders, which are taxable in non-retirement accounts. Funds that trade frequently may generate higher short-term capital gains, creating a larger tax burden. Tax-efficient funds use strategies like holding securities long-term to minimize distributions.
Regulatory Requirement
Regulation: SEC (U.S.) - Investment Company Act of 1940
