6.1 Mutual Funds
Mutual funds pool money from many investors to invest in a diversified portfolio of securities. They are one of the most popular investment vehicles for individual investors, offering professional management, diversification, and liquidity.
Structure of Investment Companies
The Investment Company Act of 1940 regulates three types of investment companies:
Open-End Funds (Mutual Funds): Continuously issue and redeem shares at NAV
Closed-End Funds: Fixed number of shares; trade on exchanges
Unit Investment Trusts (UITs): Fixed, unmanaged portfolio with termination date
This section focuses on open-end mutual funds, which are the most common type.
Net Asset Value (NAV)
NAV is the price at which mutual fund shares are bought and sold. It represents the per-share value of the fund's assets.
NAV Calculation
NAV = (Total Assets - Liabilities) / Shares Outstanding
Key NAV Rules
Calculation Timing: At least once daily after market close (4:00 PM ET)
Forward Pricing: Orders received today execute at today's closing NAV
Same-Day Pricing: Orders before 4 PM get that day's NAV; after 4 PM get next day's
Example Calculation
A mutual fund has:
- Total assets: $330 million
- Liabilities: $15 million
- Outstanding shares: 10 million
NAV = ($330M - $15M) / 10M = $315M / 10M = $31.50 per share
In Practice
An investor places an order at 2:00 PM to purchase mutual fund shares. Since the order was placed before 4:00 PM, it will be executed at that day's closing NAV. The investor won't know the exact purchase price until after the market closes.

Money Market Funds: Investment Focus - Short-term debt securities. Key Feature: Seek stable $1.00 NAV
International Funds: Investment Focus - Foreign securities only. Key Feature: Currency risk
Global Funds: Investment Focus - Both U.S. and foreign. Key Feature: Geographic diversification
Target-Date Funds: Investment Focus - Asset mix adjusts over time. Key Feature: "Set and forget" retirement
Money Market Funds
Money market funds invest in short-term, high-quality debt instruments and seek to maintain a stable $1.00 NAV.
Types of Money Market Funds
Government Money Market: Investments - Treasury bills, agency securities. NAV: Fixed $1.00
Prime Money Market: Investments - Commercial paper, CDs, repos. NAV: Floating NAV (institutional)
Tax-Exempt Money Market: Investments - Short-term municipal securities. NAV: May float
2014 SEC Reforms
- Government funds: Can maintain $1.00 fixed NAV
- Institutional prime/muni funds: Must use floating NAV
- Retail prime/muni funds: Can maintain $1.00 NAV with gates/fees
On the Exam: Money market funds seek to maintain a stable NAV but are not guaranteed. Unlike FDIC-insured bank accounts, money market funds can "break the buck" (fall below $1.00), though this is rare.
Index Funds
Index funds use passive management to replicate the performance of a benchmark index.
Characteristics
- Low expense ratios: No active management costs
- Tax efficient: Low turnover means fewer capital gains distributions
- Full market exposure: Own all (or representative sample of) index constituents
- Tracking error: Small difference between fund and index returns
Common Indexes Tracked
S&P 500: 500 large-cap U.S. stocks
Dow Jones Industrial Average: 30 blue-chip stocks
Russell 2000: 2,000 small-cap stocks
Bloomberg Aggregate Bond: U.S. investment-grade bonds
MSCI EAFE: International developed markets
Management Styles
Active vs. Passive Management
Goal: Active Management - Beat the benchmark; Passive Management - Match the benchmark
Expense Ratio: Active Management - Higher (0.5%-1.5%+); Passive Management - Lower (0.03%-0.20%)
Turnover: Active Management - Higher; Passive Management - Lower
Tax Efficiency: Active Management - Lower; Passive Management - Higher
Examples: Active Management - Stock-picking funds; Passive Management - Index funds
In Practice: Studies consistently show that most actively managed funds underperform their benchmark index over long periods, especially after accounting for higher fees. This has driven massive growth in index fund assets.
Mutual Fund Distributions
Mutual funds must distribute substantially all income and realized capital gains to shareholders to maintain their tax-advantaged status.
Types of Distributions
Ordinary Dividends: Source - Interest, dividends received. Tax Treatment: Ordinary income (or qualified rates)
Capital Gains: Source - Profits from selling securities. Tax Treatment: Short-term or long-term rates
Return of Capital: Source - Distribution of investor's own capital. Tax Treatment: Tax-deferred; reduces basis
Ex-Dividend Date
On the ex-dividend date, the fund's NAV drops by the distribution amount. Buying just before the ex-date means receiving a distribution you'll owe taxes on - don't confuse this with "free money."
Key Takeaways
- Mutual funds calculate NAV once daily after market close using forward pricing
- Open-end funds continuously issue and redeem shares; closed-end funds have fixed shares
- Growth funds focus on capital appreciation; income funds focus on current income
- Index funds passively track benchmarks with low fees and high tax efficiency
- Money market funds seek stable $1.00 NAV but are not guaranteed
- All distributions reduce NAV by the distribution amount on the ex-date
