ETF vs mutual fund vs individual stock

Investors can hold the stock market through three main vehicles: individual stocks, mutual funds and exchange-traded funds (ETFs). All three give you exposure to company profits, but they differ in how they trade, what they cost, how they are taxed and how much work they leave to you. None is better in every situation. Each makes different trade-offs.

The three vehicles in brief

• Individual stock. You buy shares of one company and own a piece of that business (see what is a stock). Your results depend on that company alone.
• Mutual fund. A pool of investors' money run by a manager and invested in many securities. You buy and sell shares of the fund directly with the fund company, usually through a broker, at a price set once a day.
• ETF. A fund that also holds a basket of securities, but whose shares trade on an exchange throughout the day (see what is an ETF).

Side-by-side comparison

Details vary by fund and provider, so read each fund's prospectus and fee table.

Costs

An individual stock has no ongoing management fee, though trading costs such as the bid-ask spread apply. Funds charge an annual expense ratio, a percentage of assets deducted from the fund. Some mutual funds also charge sales commissions, called loads, or ongoing distribution fees; many ETFs and no-load mutual funds do not.

Example (illustrative numbers)

You invest $10,000 in three ways:

A $70 yearly gap looks small, but fees come out every year and reduce the base on which future growth compounds. An active fund needs to earn back its higher fee through better performance just to keep pace, and published comparisons of active funds with their benchmarks have repeatedly found that a majority trail over long periods. The single stock carries no fund fee but takes on company-specific risk.

Taxes

In a taxable account:

• Stocks. You owe capital gains tax when you sell at a profit, and dividends are taxed as they are paid. You choose when to sell.
• Mutual funds. When managers sell holdings at a gain, the fund passes those gains to investors, who owe tax even if they did not sell any fund shares.
• ETFs. The in-kind creation and redemption process lets many ETFs avoid selling holdings, so they often distribute fewer capital gains, although this depends on the fund.

Inside tax-advantaged retirement accounts these differences matter less. Rules differ by country and change over time. See capital gains and dividend tax basics.

Diversification and risk

A single stock can fall 50% or more on bad news about one company. A fund holding hundreds of stocks is much less exposed to one company's failure, but it is still fully exposed to a market decline. Diversification reduces company-specific risk, not market risk (see diversification explained). Concentrated funds, such as a single-sector ETF or a narrow mutual fund, give you less diversification than a broad one.

Which trade-offs matter most

Think about what you want from your money:

• Control and learning. Individual stocks give you full control over what you own, and they reward research, but they need time and tolerance for big swings in single positions.
• Convenience and spread of risk. Funds hand the choice of holdings to an index or a manager. They suit people who want broad exposure without picking companies.
• Trading flexibility. If you want to trade during the day or use limit orders, an ETF or stock fits. A mutual fund trades only at the daily price.
• Automatic investing. Mutual funds have long allowed automatic, fixed-dollar purchases, and many brokers now offer similar features for stocks and ETFs through fractional shares.

Many people use a mix, for example a broad fund for the core of a portfolio and a few individual stocks. How to divide money among assets is covered in asset allocation.

Common mistakes and limits

• Assuming funds are always safer. A fund focused on a narrow theme can be riskier than a diversified set of individual stocks.
• Overlooking overlap. Owning several funds, plus individual stocks, can leave you holding the same big companies several times.
• Ignoring the whole cost. Compare the expense ratio, trading spread, sales loads and taxes.
• Picking by recent returns. Last year's best fund or stock is no guarantee of the next year.

Where to see it on StocksXray

StocksXray focuses on individual S&P 500 stocks. If you choose to own single companies, the scanner and stock pages such as Microsoft's give you a starting point for research. If you prefer funds, the same company data can show you what is inside the index they track.

Key takeaways

• Stocks, mutual funds and ETFs differ mainly in diversification, fees, trading style and tax treatment.
• ETFs trade all day like stocks; mutual funds transact once daily at NAV.
• Funds charge an annual expense ratio; individual stocks do not, but concentrate risk.
• Funds spread company-specific risk but not market risk.
• The right mix depends on your goals, time and temperament.
