What’s the best long-term investment?

What’s the best long-term investment? Because you’re a money nerd (and a GRS reader), I hope your answer to this question was, “Stocks!” If the future is anything like the past, that’s the correct answer. History has shown that stocks are the best long-term investment — and by a wide margin.

Unfortunately, most Americans believe otherwise.

As a part of its annual Economy and Personal Finance survey (conducted during the first two weeks of April), Gallup News asked 1017 American adults, “Which of the following do you think is the best long-term investment: bonds, real estate, savings accounts or CDs, stocks or mutual funds, or gold?”

Here’s how people answered:

  • 35% of respondents said that real estate is the best-long term investment
  • 21% said that stocks or mutual funds are the best long-term investment
  • 17% said that savings accounts or certificates of deposit are the best long-term investment
  • 16% said gold is the best long-term investment
  • 8% said bonds are the best long-term investment

Americans' views on the best long-term investment

While acknowledging that past results are no guarantee of future performance — let’s take a look at why I think Americans haven’t got a clue when it comes to figuring out the best long-term investment strategy.

The Rate of Return on Everything

The August 2019 issue of The Quarterly Journal of Economics included a paper entitled “The Rate of Return on Everything, 1870-2015”. Over an astounding 74 pages of discussion, the authors attempt to analyze the long-term (145-year) rate of return on a variety of assets around the world.

The paper examines four popular investment vehicles:

  • Bills, by which the authors mean Treasury bills, are short-term government bonds. At present, these are a good proxy for the rates you can earn with a high-yield savings account. (I don’t think this is always the case, though.)
  • Bonds, which in this case refers to ten-year government bonds (such as a 10-year Treasury note).
  • Equity, which is another way to describe common stock. Here, the authors are measuring overall stock market performance.
  • Housing, including rental properties.

We’ll look at each of these in greater detail in a moment (and we’ll look at gold too), but for now let’s look at this paper’s overall findings. While the authors looked at data for many countries, I’m only going to share results for the U.S. The following table shows the rates of return for these different asset classes over three different time periods. (Remember that, for our purposes, Bills are a stand-in for savings accounts.)

Long-term returns on certain asset classes

From this table, it’s clear that equities (i.e., stocks) have been the highest return investments over long periods of time. Nothing else comes close. (Outside the U.S., this isn’t always true.)

Now, while stocks provide the best long-term returns, they also come with the greatest volatility. Here’s a a chart (Figure VII) from the paper that shows just how crazy the ride with stocks can be. (Also note how closely equities and real estate tracked each other until the Great Depression.)

Equity returns vs. real-estate returns

It’s this volatility that scares so many people away from the stock market. They’re afraid that a sharp decline can come at any time. And that’s true. But what’s also true is that a prolonged bull market can occur at anytime, as we experienced from March 2009 to February 2020! If you’re a long-term investor, you don’t give a fig about short-term market movement.

Let’s dive deeper into the long-term investment returns provided by the asset classes in the Gallup poll: real estate, stocks, savings accounts, gold, and bonds.

Real Estate (35% of Respondents)

Real estate as a long-term investment is complicated. Yes, it absolutely can be a great option, but not in the way most Americans imagine.

When you talk to the average person about investing in real estate — or when you poll them about best long-term investments — they’re probably thinking of homeownership, not rental or commercial properties. From my experience, most people think of buying a home as a path to wealth. Unfortunately, this is mostly just propaganda from the real-estate industrial complex.

During the past two decades, residential real estate has indeed provided good returns — if you’ve timed your moves right. I’ve been lucky. I’ve bought and sold at the right time, so I’ve done well during the past twenty years. But I’m sure we all know people who suffered during when the housing bubble burst in 2008. (My brother is a prime example. He lost two homes at the time.)

The past two decades have been unusual, however.

Yale economics professor Robert Shiller has become the authority on the history of home prices in the U.S. At his website, he provides a spreadsheet that shows home prices from 1890 to present. Here’s a graph from that spreadsheet.

Robert Shiller historical home price data

Historically, home prices have tended to remain relatively flat for long periods of time. Most investment pros seem to figure that residential real estate offers about a 1% annual rate of return. And, in fact, in the “Rate of Return on Everything” paper, the authors calculate that in the United States, while the real return on real estate has been been 6.10% since 1870, the return on home prices has been only 0.90%.

Wait, what?

In the paper, housing returns include two discrete components: property appreciation and rental returns. When the authors say that real estate has offered a long-term investment return of 6.10%, what they mean is:

  • Home prices have increased at an average of 0.90% over the long term, and
  • Rental income (both actual and imputed) has provided the remainder of that return.

So, rental real estate can provide excellent long-term returns, although those returns are generally not as high as the returns you could enjoy in the stock market. But homeownership? Historically, homeownership is not a profitable long-term investment strategy. Yet when we return to the Gallup poll in which 35% of Americans believe that real estate is currently the best long-term investment strategy, homeownership is probably what they’re talking about.

There are plenty of reasons to own, but wealth isn’t one of them.

Stocks and Mutual Funds (21% of Respondents)

While I’m pleased that 21% of respondents in the Gallup survey believe that stocks and mutual funds are the best long-term investment right now, I’m also disappointed that this number is so low.

Over and over and over again, the data has shown the same thing: If you’re investing for the future, stocks are the best choice. This is especially true after the market has dropped.

I know market downturns can be scary, but here’s the thing: Volatility is one of the fundamental features of stocks. On average, the stock market returns 10% per year (around 7% when adjusted for inflation). But average is not normal.

Recent history is typical. The following table shows the annual return for the S&P 500 over the past twenty years (not including dividends):

S&P 500 annual returns

The S&P 500 earned an average annualized return of 6.06% for the twenty-year period ending in 2019. But zero of these years generated stock market returns close to the average for that time span. (2007 came closest to average with a return of 3.53% — still more than 2.50% off the average.)

Short-term market movements aren’t an accurate indicator of long-term performance. What a stock or fund did last year doesn’t tell you much about what it’ll do during the next decade. The “Return on Everything” paper found that stocks enjoyed average long-term returns of about 9% after inflation. Other academic studies put this number at closer to 7%. Whichever number you use, the long-term returns on stocks are still higher than any of the other options in the Gallup poll.

It’s important to note that when I’m talking about the long-term returns on stocks and mutual funds, I’m talking about the returns of the market as a whole. Individual stocks can experience radically different fates. Fortunately, index funds effectively allow you to own the entire market, which means you don’t have to worry about picking the “right” stocks. For more info, see our guide on how to invest.

Savings Accounts and Certificates of Deposit (17% of Respondents)

There’s not much to say about the long-term performance of investments that come with a fixed rate of return. Generally speaking, what you see is what you get.

If you take out a five-year certificate of deposit at a 1.60% APY — which is a current “good” rate — then you’re going to earn 1.6% on your money every year. It’s a sure thing. Unfortunately, it’s also about the same as the current rate of inflation, which means that you’re real return is effectively zero. You’re not gaining anything, but you’re not losing anything either.

As you know, savings accounts usually offer lower rates than CDs. According to the FDIC, the current national average for savings accounts is 0.07%. (Their data shows the current national average for a five-year CD is 0.58%.) If you use a high-yield online savings account, you can find interest rates close to what you’d earn on a certificate of deposit.

Here, for instance, are a couple of current top offers:

So, CDs and savings accounts don’t offer very high returns right now. In fact, interest rates have been low for a decade. Looking at historical interest rate data, deposit accounts have never made sense for long-term investing. And the only time they make sense for short-term investing is during periods of high inflation. (These accounts always make sense for an emergency fund or an opportunity fund, though.)

Going back to the Gallup poll, 17% of Americans believe that savings accounts and CDs are currently the best long-term investments. Let me make a (not-so) bold prediction: These folks are wrong. Sticking your money in savings is like treading water. You won’t drown, but you’re not going to get anywhere either.

Gold (16% of Respondents)

Last week, I shared a rant about why investing in gold isn’t a smart long-term plan. Because this article isn’t actually about gold, today I’ll be brief.

You’ll note that the academic paper I cited earlier — the one with the info about the rates of return for “everything” — didn’t include gold or other precious metals. Do you know why? Because despite what some people will tell you, investing in gold is a lousy long-term strategy.

In his book Stocks for the Long Run, finance professor Jeremy Siegel breaks out the long-term performance of a variety of asset classes. His conclusions are similar to (but not the same) as those in the “Return on Everything” paper. Siegel found that between 1871 and 2012, gold provided a real return of 1.0%. Since 1946, that return has been 2.0%.

Can gold outperform stocks over the short term? Yes, absolutely! According to Siegel, gold provided an 11.8% real return between 2000 and 2012. Stocks appreciated only 0.3% during that span. But since 2012? Well, the price of gold hasn’t increased at all while the S&P 500 has more than doubled. (More on this at the end of the article.)

Let’s return to the Gallup poll that inspired this article. Is gold the best long-term investment right now? Apparently 16% of Americans believe so. I find this foolish.

At the moment I write this, gold is selling for $1714.62 an ounce. This isn’t a record price, but it’s high. (Gold’s nominal peak price was $1889.70 per ounce on 22 August 2011. Gold’s inflation-adjusted high was about $2500 per ounce back in 1973.) I find it difficult to believe — impossible, really — that buying gold near its peak is a smart long-term play, especially given its history of low returns over long time spans. If these 16% of Americans are buying gold as a long-term investment, I suspect they’re going to be sorely disappointed.

Gold can have uses in an investment portfolio. Long-term growth isn’t one of them.

Bonds (8% of Respondents)

Humble bonds brought up last place in the Gallup poll of best long-term investments. Only 8% of Americans chose them as the best place to put money for the long run. Honestly, I can’t argue with this result — and that’s not simply because I don’t know a lot about bonds!

At the moment, if you were to purchase a 30-year U.S. government bond, it’d pay you a fixed rate of 2%. A ten-year bond would pay 1.5%.

Obviously, these rates are slightly better than you could achieve with a high-yield savings account. They’re about double the long-term average for home price appreciation. And they’re about the same long-term return you’d expect from gold.

That’s not always the case, of course.

The “Rate of Return on Everything” paper found that bonds yield long-term inflation-adjusted returns of just under three percent per year. (Since 1980, bonds have achieved returns averaging 5.90%, which is slightly better than rental properties during that timespan.)

Jeremy Siegel’s bond numbers are similar. He shows they earned an average of 3.0% per year between 1871 and 2012. He says that since 1926, bonds have yielded an average of 2.6%. Since 2000, that return is 6.5%.

But for now? Today? Bonds aren’t a great option.

The Best Long-Term Investment

To its credit, Gallup seems to be aware that their poll doesn’t reflect the actual value of long-term investments; it simply reflects the attitudes of the people they surveyed.

In August 2011, Gallup published results of a similar poll. At that time, a shocking 34% of people said that gold was the best long-term investment. Only 17% believed that stocks were the best long-term investment.

2011 survey about the best long-term investment

“Men, seniors, middle-income Americans, and Republicans are more enamored with gold,” Gallup wrote at the time. “That one in three Americans see gold as the best long-term investment may indicate a bubble in the value of this precious metal — something that may be corroborated if gold continues to plunge.”

In fact, gold was entering a bubble during 2011. (And it appears to be entering one now.) Here’s a little table I whipped up to compare the values of each investment in the Gallup survey — now and in 2011. (The table is a little goofy since there’s no consistent unit of measure, but you get what I’m going for.)

Changes in value since 2011

So, in the 8-1/2 years since Gallup noted the goldbugs were out in force:

  • The price of gold has essentially remained unchanged. (In reality, it dropped sharply in 2013, but has been climbing for the past eighteen months.)
  • Real estate has done well since August 2011. Home prices in the U.S. have increased by an average of 50%. (This is abnormal, though, and makes me worried that we’re once again in a housing bubble.)
  • The S&P 500 has jumped by 141% in the past 8-1/2 years. You might argue we’re in a stock bubble too, and I’d buy that argument. But still: This is nearly triple the return of housing.
  • Meanwhile, if you’d purchased a 5-year CD or a 10-year Treasury bill, your rates would have been locked in at 1.47% and 3.14%, respectively.
  • So, how have the five investment types in the Gallup poll performed over 8-1/2 years?

    Stocks were the clear winner. Real estate came second, bonds were third, and savings accounts were fourth. Gold — the runaway “best long-term investment” answer in August 2011 — was the worst possible choice. If you had bought gold as a long-term investment in 2011, you would have actually lost purchasing power in the interim due to erosion from inflation.

    Now, I realize that 8-1/2 years isn’t really long-term. It’s sort of medium-term. Twenty years or thirty years is long-term. But, if anything, I expect that in 2031, we’ll be able to look back and see that these results become even more pronounced. Gold will still be treading water — because that’s what it does — and stocks will have gained even more.

    What about Bitcoin and other cryptocurrencies? Well, cryptocurrencies are not investment vehicles — or shouldn’t be. They’re currencies, mediums of exchange. (And they’re barely even that.) If you put money into Bitcoin in attempt to earn a profit, you’re not investing. You’re speculating. You may indeed experience gains, and that’s great. But don’t fool yourself that what you’ve done qualifies as investing.

    Here’s the bottom line on this Gallup poll: Generally speaking, Americans have no idea which is the best long-term investment because they don’t understand history and they don’t understand investing.

    Surveys like this are more like thermometers. They reveal the current “temperature” of whatever’s being surveyed (investment options, in this case). They don’t actually provide factual information that you should act on. Just because more than one-third of Americans believe that real estate is the best way to investment money long term, that doesn’t mean they’re right.
