Exchange-traded funds, or ETFs, are an easy way to begin investing. ETFs are fairly simple to understand and can generate impressive returns without much expense or effort. Here’s what you should know about ETFs, how they work, and how to buy them.

What is an ETF?

What is an ETF?

An exchange-traded fund, or ETF, allows investors to buy many stocks or bonds at once. Investors buy shares of ETFs, and the money is used to invest according to a certain objective. For example, if you buy an S&P 500 ETF, your money will be invested in the 500 companies in that index.

ETFs vs. mutual funds

ETFs vs. mutual funds

One common question is how ETFs differ from mutual funds since the basic principle is the same.

The key difference between these two types of investment vehicles is how you buy and sell them. Mutual funds are priced once per day, and you typically invest a set dollar amount. Mutual funds can be purchased through a brokerage or directly from the issuer, but the key point is that the transaction is not instantaneous.

On the other hand, ETFs trade just like stocks on major exchanges such as the NYSE and Nasdaq. Instead of investing a set dollar amount, you choose how many shares you want to purchase. Because they trade like stocks, ETF prices continuously fluctuate throughout the trading day, and you can buy shares of ETFs whenever the stock market is open.

ETFs vs mutual funds: ETFs allow investors to buy many stocks or bonds, are traded on an exchange, and traded whenever the stocks market is open. Mutual funds allow investors to pool money together, are bought directly from the company, and priced daily.

Understanding ETF basics

Understanding ETF basics

Before we get any further, there are a few concepts that are important to know before you buy your first ETFs.

  • Passive vs. active ETFs: There are two basic types of ETFs. Passive ETFs (also known as index funds) simply track a stock index, such as the S&P 500. Active ETFs hire portfolio managers to invest their money. The key takeaway: Passive ETFs want to match an index’s performance. Active ETFs want to beat an index’s performance.
  • Expense ratios: ETFs charge fees, known as the expense ratio. You’ll see the expense ratio listed as an annual percentage. For instance, a 1% expense ratio means that you’ll pay $10 in fees for every $1,000 you invest. All things being equal, a lower expense ratio will save you money.
  • Dividends and DRIPs: Most ETFs pay dividends. You can choose to have your ETF dividends paid to you as cash, or you can choose to have them automatically reinvested through a dividend reinvestment plan, or DRIP.

Understanding ETF taxes

Understanding ETF taxes

If you buy ETFs in a standard brokerage account (not an IRA), you should know that they could result in taxable income. Any gains you make from selling an ETF will be taxed according to capital gains tax rules, and any dividends you receive will likely be taxable as well.

Of course, if you invest in ETFs through an IRA, you won't have to worry about capital gains or dividend taxes. In a traditional IRA, money in the account is only considered taxable income after it is withdrawn, while Roth IRA investments aren't taxable at all in most cases.

How much money do you need to be able to invest in ETFs?

How much money do you need to be able to invest in ETFs?

ETFs don’t have minimum investment requirements -- at least not in the same sense that mutual funds do. However, ETFs trade on a per-share basis, so unless your broker offers the ability to buy fractional shares of stock, you’ll need at least the current price of one share to get started.

Pros and Cons of ETFs

Pros and Cons of ETFs

Advantages to investing in ETFs:

  • ETFs provide exposure to a variety of stocks, bonds, and other assets, typically at a minimal expense.
  • ETFs take the guesswork out of stock investing. They allow investors to match the market’s performance over time, which has historically been quite strong.
  • ETFs are more liquid (easy to buy and sell) than mutual funds. Online brokers make it easy to buy or sell ETFs with a simple click of the mouse.
  • It can be extremely complicated to invest in individual bonds, but a bond ETF can make the fixed-income portion of your portfolio very easy.

Potential drawbacks of ETFs:

  • Since ETFs own a diverse assortment of stocks, they don’t have quite as much return potential as buying individual stocks.
  • ETFs are often low-cost, but they aren’t free. If you buy a portfolio of individual stocks on your own, you won’t have to pay any management fees.

How to start investing in ETFs

How to start investing in ETFs

Step 1: Open a brokerage account.

You’ll need a brokerage account before you can buy or sell ETFs. The majority of online brokers now offer commission-free stock and ETF trades, so cost isn’t a major consideration. The best course of action is to compare each broker’s features and platform. If you’re a new investor, it might be a good idea to choose a broker that offers an extensive range of educational features, such as TD Ameritrade (NASDAQ:AMTD), E*Trade (NASDAQ:ETFC), or Schwab (SCHW 0.54%), but there are several other excellent brokers to choose from.

Step 2: Choose your first ETFs.

For beginners, passive index funds are generally the best way to go. Index funds are cheaper than their actively managed counterparts, and the reality is that most actively managed funds don’t beat their benchmark index over time.

With that in mind, here’s a list of ETFs, and a brief description of what each invests in, for beginners who are just starting to build their portfolios:

10 of the Best ETFs for Beginners

ETF Examples: 10 of the Best ETFs for Beginners

  1. Vanguard S&P 500 ETF (VOO 0.63%) -- Large U.S. companies
  2. Schwab U.S. Mid-Cap ETF (SCHM -0.08%) -- Midsize U.S. companies
  3. Vanguard Russell 2000 ETF (NYSEMKT:VTWO) -- Smaller U.S. companies
  4. Schwab International Equity ETF (SCHF 0.03%) -- Larger non-U.S. companies
  5. Schwab Emerging Markets Equity ETF (SCHE 0.12%) -- Companies from countries with developing economies
  6. Vanguard High-Dividend ETF (VYM 0.14%) -- Stocks that pay above-average dividends
  7. Schwab U.S. REIT ETF (SCHH 0.0%) -- Real estate investment trusts
  8. Schwab U.S. Aggregate Bond ETF (SCHZ -0.13%) -- Bonds of all different varieties and maturity lengths
  9. Vanguard Total World Bond Fund (BNDW -0.09%) -- Includes international bonds as well as U.S. bonds of various lengths and maturities.
  10. Invesco QQQ Trust (QQQ 0.95%) - Tracks the Nasdaq-100 Index, which is heavy on tech and other growth stocks.

You might notice that this list is heavy on Vanguard and Schwab. There’s a good reason for this: Both are dedicated to offering Americans access to the stock market at a minimal expense, so ETFs from both tend to be among the cheapest in the business.

Step 3: Let your ETFs do the hard work for you.

It’s important to keep in mind that ETFs are generally designed to be maintenance-free investments.

Newer investors tend to have a bad habit of checking their portfolios far too often, and making emotional, knee-jerk reactions to major market moves. In fact, the average fund investor significantly underperforms the market over time, and over-trading is the main reason. So, once you buy shares of some great ETFs, the best advice is to leave them alone and let them do what they’re intended to do: produce excellent investment growth over long periods of time.

The Motley Fool: Are ETFs good for beginner investors?

Dr. A. Seddik Meziani: ETFs are an easy way to invest. They are rightly considered an ideal entry point into the market for fledgling investors thanks to their simplicity, low upfront cost, simple fee structure, and ease of trade. Also, beyond an ETF share price, there is no minimum amount to invest, unlike for mutual funds. Any broker can turn an investor into a new ETF holder via a straightforward brokerage account. Investors can easily access the market or submarket they want to be in. It is easily done through an ETF that tracks it.

The Motley Fool: Is an ETF considered safer than an index fund to mitigate risk? Or vice versa?

Dr. A. Seddik Meziani: To be clear, many ETFs are an “index fund” in that they also track an index, just with different terms and conditions. That being said, most ETFs can be used to mitigate risk since they are generally inherently diversified via their underlying baskets of securities which offer a widening range of asset classes. Like index funds, they cannot, however, fully eliminate risk such as market risk or counterparty and credit risk inherent in an ETF structure.

The Motley Fool: Are ETFs considered safer than stocks? Why or why not?

Dr. A. Seddik Meziani: ETFs are generally considered safer to own than individual stocks because of their wide array of underlying holdings which provide the benefits of diversification. Generally, it’s safer to hold a group of stocks rather than just one stock. In other words, ETFs eliminate exposure to individual securities risk.

The Motley Fool: How do ETFs help with diversification? Is it possible to over-diversify your ETF portfolio?

Dr. A. Seddik Meziani: Diversification is a widely accepted framework for managing investments. ETFs help with diversification especially if the underlying portfolios include multiple asset classes. But like everything else, diversification also has its limits. It should be practiced in moderation. The role of diversification is to reduce investment risk. Taking it too far, however, could lead to portfolio bloat and overdiversification. It happens when the additional benefit of reducing risk via diversification begins to be outweighed by the marginal loss of the expected return. Holding more stocks simply for the sake of having more holdings and not thinking about how the risk of each additional stock balances against the risk of the existing stocks is not a good investment strategy.
