Understanding the world of investment instruments can be overwhelming, particularly when it comes to mutual funds and exchange-traded funds (ETFs). Whether you’re a beginner in investing or looking to enhance your expertise, knowing the terminology is critical for making sound investing decisions.

The Best Glossary of Mutual Funds and ETFs: Everything You Need to Know

This thorough glossary defines essential terminology connected to mutual funds and ETFs, allowing you to confidently understand various financial options. From basic to complex concepts, we’ve compiled all you need to know in one accessible place.

Basic Investment Terms

Mutual Fund

Definition: An investment vehicle that combines funds from different participants to buy a diverse portfolio of stocks, bonds, or other assets that is professionally managed to achieve certain investment goals.

Fidelity Contrafund, for example, is a large-cap growth mutual fund that predominantly invests in growth-orientated companies in the United States.

Exchange-Traded Fund (ETF)

Definition: A stock exchange-traded investment fund that owns assets such as stocks, bonds, or commodities and is often meant to track the performance of an index.

SPDR S&P 500 ETF (SPY), for example, tracks the S&P 500 index’s performance.

Net Asset Value (NAV)

Definition: A fund’s per-share value is computed by dividing the total value of all assets in the portfolio minus liabilities by the number of outstanding shares.

For example, if a mutual fund has $100 million in assets, $5 million in liabilities, and 5 million outstanding shares, its net asset value is $19 per share.

Expense Ratio

Definition: The annual fee charged to shareholders by funds, represented as a percentage of assets under management, to cover operational costs, management fees, and administrative expenses.

For example, a 0.75% expenditure ratio means you’ll pay $7.50 per $1,000 invested each year.

Load

Definition: A sales charge or commission paid while purchasing (front-end load) or selling (exit load) mutual funds.

For example, a fund with a 5% front-end load will deduct $500 from a $10,000 investment before buying shares.

No-Load Fund

Definition: A mutual fund that does not charge a sales commission or load when shares are bought or sold.

For example, the Vanguard Total Stock Market Index Fund Investor Shares is a well-known no-load fund.

Fund Structure and Operations

Open-End Fund

Definition: A mutual fund that issues new shares to investors and redeems them when they sell, having no restriction on the number of shares that can be issued.

Most classic mutual funds, such as the T. Rowe Price Blue Chip Growth Fund, are open-ended.

Closed-End Fund

Definition: A fund that issues a fixed number of shares through an initial public offering and subsequently trades on stock markets, frequently at prices higher (premium) or lower (discount) than its NAV.

For example, Adams Diversified Equity Fund (ADX) is a closed-end fund that has been in operation since 1929.

Creation/Redemption Mechanism

Definition: A method peculiar to ETFs in which specialised institutional investors known as authorised participants establish or redeem big blocks of ETF shares (called creation units) directly with the fund provider.

For example, if demand for an ETF increases, authorised participants can issue extra shares by delivering the underlying basket of securities to the ETF issuer.

Creation Unit

Definition: A large block of ETF shares (usually 25,000 to 200,000) that authorised participants can issue or redeem on the primary market.

For example, an approved participant could trade a portfolio of stocks that correspond to the S&P 500 index for 50,000 shares of an S&P 500 ETF.

Investment Strategies and Types

Index Fund

Definition: A mutual fund or ETF that holds the same securities in the same amounts as a specific market index to replicate its performance.

Vanguard Total Bond Market Index Fund, for example, tracks the Bloomberg Barclays US Aggregate Bond Index.

Actively Managed Fund

Definition: A fund in which portfolio managers make precise investment decisions with the goal of outperforming a benchmark index using research, market predictions, and expert opinion.

For example, the American Funds Growth Fund of America is an actively managed fund that aims to deliver capital growth.

Passive Management

Definition: An investing strategy that seeks to mimic market returns by duplicating a specific index, which usually results in reduced costs and less frequent trading.

For example, the iShares Core S&P 500 ETF (IVV) tracks the S&P 500 index through passive management.

Smart Beta

Definition: An investing strategy that uses alternative index creation principles rather than typical market capitalisation weighting with the goal of increasing returns, lowering risk, or improving diversity.

For example, the Invesco S&P 500 Equal Weight ETF (RSP) weights each S&P 500 business equally rather than according to market capitalisation.

Sector Fund

Definition: A fund that focuses its investments on a certain industry or sector of the economy.

For example, the Fidelity Select Health Care Portfolio focuses on healthcare-related companies.

Balanced Fund

Definition: A fund that invests in a variety of asset classes, most commonly equities and bonds, in order to combine growth potential with income and risk management.

For example, the Vanguard Wellington Fund invests roughly 60 per cent in equities and 40 per cent in bonds.

Performance Metrics

Total Return

Definition: The total return on an investment stated as a percentage, comprising capital appreciation and income (dividends and interest).

For example, if a fund’s NAV rises from $10 to $11 and it distributes a $0.50 dividend, the total return is 15%.

Alpha

Definition: A measure of a fund’s performance in comparison to its benchmark, reflecting whether the fund manager added or lost value relative to the market.

For example, an alpha of 2.0 indicates that the fund exceeded its benchmark by 2 percentage points.

Beta

Definition: A measure of a fund’s volatility or systematic risk in comparison to the market, with a beta of 1.0 indicating that the fund moves with the market.

For example, a beta of 1.2 indicates that the fund will increase or fall 20% more than its benchmark index.

Tracking Error

Definition: The price differential between an index fund or ETF and the benchmark it is supposed to replicate.

For example, an S&P 500 index fund with a tracking error of 0.05% closely mirrors the index’s results.

Sharpe Ratio

Definition: A risk-adjusted return determined by dividing a fund’s excess return (above the risk-free rate) by its standard deviation.

For example, a fund with a Sharpe ratio of 1.5 generates a higher return per unit of risk than a fund with a ratio of 1.0.

Distribution and Taxation

Capital Gains Distribution

Definition: The payment to fund shareholders of the proceeds from the sale of appreciated securities.

For example, a mutual fund that sells stocks it has held for years at a profit may distribute $2 per share in capital gains to its shareholders.

Dividend Distribution

Definition: The payout to fund shareholders of revenue from the fund’s investments, such as stock dividends or bond interest.

For example, a bond fund may pay out monthly dividends representing interest generated on its bond assets.

Tax Efficiency

Definition: A measure of how well a fund reduces taxable payouts to shareholders, usually through tactics such as low portfolio turnover or tax-loss harvesting.

ETFs, for example, are frequently more tax-efficient than mutual funds since the creation/redemption procedure reduces capital gains dividends.

Tax-Cost Ratio

Definition: The percentage of an investor’s assets that is taxed, representing the difference between pre-tax and after-tax returns.

For example, a tax-cost ratio of 0.8% indicates that an investor loses 0.8 percentage points of return each year due to taxes.

Advanced Concepts

Premium/Discount

Definition: The percentage difference between the market price of an ETF and its NAV. When the market price exceeds NAV, a premium is incurred; when the market price falls below NAV, a discount occurs.

For example, a $51 ETF with a $50 NAV has a 2% premium.

Bid-Ask Spread

Definition: The difference between the greatest price a buyer is ready to pay (bid) and the lowest price a seller is willing to accept (ask) for an exchange-traded fund.

For example, if an ETF’s bid price is $25.00 and the ask price is $25.05, the bid-ask spread is $0.05, or 0.2%.

Liquidity

Definition: The rate at which an ETF or mutual fund can be bought or sold without impacting its price.

For example, the SPDR S&P 500 ETF (SPY) is very liquid, trading millions of shares per day with narrow bid-ask spreads.

Rebalancing

Definition: The process of realigning asset weights in a portfolio in order to retain the original or targeted level of asset allocation.

For example, following a strong stock market surge, a balanced fund may sell some stocks and purchase bonds to return to its target 60/40 allocation.

Securities Lending

Definition: A process in which mutual funds and ETF providers temporarily loan stocks from their portfolios to other investors (mostly short sellers) in exchange for a fee, potentially increasing returns.

For example, an S&P 500 ETF may lend part of its Apple shares to a hedge fund, resulting in additional income for the ETF’s shareholders.

Thematic ETF

Definition: An ETF that prioritises specific investment topics, trends, or concepts over standard sector classifications.

For example, the ARK Innovation ETF (ARKK) invests in companies that are focused on disruptive innovation across several sectors.

Leveraged ETF

Definition: An ETF that leverages financial derivatives and debt to increase the returns of an underlying index or benchmark.

For example, ProShares Ultra S&P 500 (SSO) seeks to outperform the S&P 500 index on a daily basis by twofold.

Inverse ETF

Definition: An ETF that seeks to outperform the index or benchmark it tracks, usually through short selling or derivatives.

For example, ProShares Short S&P 500 (SH) seeks to offer the inverse (-1x) daily performance of the S&P 500 index.

Environmental, Social, and Governance (ESG) Fund

Definition: An investment fund that considers environmental, social, and governance concerns in addition to financial considerations.

For example, the iShares ESG Aware MSCI USA ETF (ESGU) monitors an index of US companies with beneficial ESG attributes.

Exchange-Traded Note (ETN)

Definition: An unsecured debt security that tracks an underlying index but, unlike ETFs, does not own the assets and is subject to issuer credit risk.

For example, iPath Bloomberg Commodity Index Total Return ETN follows the performance of the Bloomberg Commodity Index.

Fund of Funds

Definition: A mutual fund or exchange-traded fund that invests in other funds rather than stocks, bonds, or other securities.

For example, the Vanguard Target Retirement 2045 Fund diversifies its portfolio by investing in numerous underlying Vanguard index funds.

Distribution Yield

Definition: A fund’s revenue distributed during the previous 12 months divided by its current share price, presented as a percentage.

For example, if a fund trading at $50 per share paid out $2 in income during the previous year, its distribution yield would be 4%.

FAQs

Which is better for beginners, mutual funds or ETFs?

Mutual funds are often better for beginners who want to make regular investments without trading fees, while ETFs are ideal if you prefer lower expense ratios and the flexibility to trade throughout the day. For absolute beginners with limited capital, many mutual funds have higher minimum investments compared to ETFs, which can be purchased as single shares.

How do I know if I’m paying too much in fund fees?

Actively managed funds with an expense ratio over 1% or passive index funds over 0.5% are likely overpriced. Index ETFs with lower fees charge less than 0.1%. A 1% fee differential might diminish your portfolio worth by over 20% after 25 years.

Can I lose all my money in an ETF or mutual fund?

Standard mutual funds and ETFs seldom lose all your money, but market downturns can cause big losses. Diversified funds spread risk across several securities, making ultimate loss unlikely unless all companies fail. Leveraged ETFs and sector-specific products are more likely to lose money.

What’s the easiest way to compare similar ETFs before investing?

Comparisons of similar ETFs are easiest using expense ratios, historical performance, tracking error, and trading volume. Free comparison tools on broking platforms and financial websites provide side-by-side studies. The fund’s holdings, fees, and liquidity directly affect your returns and trading efficiency, so pay attention to them.

How often should I rebalance my portfolio of ETFs and mutual funds?

ETF and mutual fund portfolios should be rebalanced once or twice a year or when they deviate more than 5-10% from targets. Consider rebalancing when stocks reach 66% of your portfolio if your goal is 60% equities and 40% bonds. Investors may also rebalance after major market occurrences or personal milestones.
