Warren Buffett: even 'the village idiot' can be an investing pro — use his dead-easy playbook to secure your retirement

Warren Buffett has spent more than eight decades investing in the stock market. But his advice for everyday investors is surprisingly simple.

And it comes down to one core belief: don’t bet against U.S. markets.

Top Picks

“America has been a wonderful place to invest money,” Buffett told CNBC’s Becky Quick (1) in a July 2026 interview.

When he bought his first stock in 1942, the Dow Jones Industrial Average had just crossed 100. On Nov. 10, 2026, it closed (2) at 52,231.89 — more than 524 times higher, without counting reinvested dividends. Those are huge gains, but the Oracle of Omaha doesn’t think it’s anything special.

“The village idiot could have made it,” Buffett joked with CNBC.

He was making the point that investors didn’t need to be stock-picking geniuses to benefit from America’s long-term economic growth.

In his 2018 letter to Berkshire Hathaway shareholders (3), Buffett showed off more of his math. A hypothetical $114.75 invested in a no-fee S&P 500 index fund in 1942 would have grown to $606,811 by January 2019, with dividends reinvested.

So why make investing harder than it needs to be? Chasing hot stocks and constantly buying and selling can get in the way of building wealth over time.

Here’s how to put Buffett’s simple philosophy to work for your retirement.

Own a broad piece of American business

Buffett has made billions identifying individual companies with strong businesses and staying invested in them. But he doesn’t expect the average investor to spend their days researching stocks and analyzing corporate balance sheets.

“My regular recommendation has been a low-cost S&P 500 index fund,” Buffett wrote in his 2016 letter to shareholders (4).

That’s likely a much easier starting point for most people because an index fund gives you exposure to a collection of companies with a single investment, rather than requiring you to pick individual winners. If you think America will still be humming along in 30 years, then an index fund tracking the S&P 500 could be a relatively safe, or at least safer, investment.

The Securities and Exchange Commission (SEC) says this kind of diversification can reduce portfolio risk (5), although it can’t eliminate losses. Popular options include the Vanguard S&P 500 ETF (NYSEARCA: VOO) and the iShares Core S&P 500 ETF (NYSEARCA: IVV).

If you prefer the hands-off, tech-forward approach to building wealth, Vanguard’s Digital Advisor puts the investing expertise of one of the world’s largest asset managers right at your fingertips.

It takes the guesswork out of investing by building a personalized portfolio for you using Vanguard’s well-known low-cost ETFs and mutual funds — then keeps things running smoothly with automatic rebalancing.

The platform also offers guidance on saving for retirement and lets you set additional goals as your life evolves. It can even help you think through debt repayment strategies, potentially freeing up more cash to invest toward your long-term plans.

With a minimum investment of just $100, it’s an easy way to get started with professionally guided investing.

For every $10,000 in an all-index portfolio, you’ll pay approximately $15 to $16 per year.*

You can even test-drive the Vanguard experience with no advisory fees for the first 90 days.

*All investing is subject to risk, including the possible loss of the money you invest.

Starting with smaller investments

You don’t need thousands of dollars sitting in a savings account before you can start investing. ETFs have made it easier for people to get exposure to the stock market, even if they’re starting with relatively small amounts.

If you’re looking to get into set-and-forget investing, you can get started with Acorns, an app that automatically invests your spare change.

How it works is simple: Just sign up and link your debit or credit cards. Then, every time you buy something, Acorns rounds up the total to the nearest dollar. This turns a morning coffee for $3.25 into a 75-cent investment in your future.

From here, that money goes into a diversified portfolio of ETFs that you can tailor to your risk tolerance. Along with big names like the Vanguard S&P 500 ETF, Acorns also sets you up to invest in specific sectors of the economy through custom portfolios. This includes areas like heavy industry, energy, consumer staples and utilities.

Then, once you’re comfortable with your round-ups, you can supercharge your savings with recurring monthly deposits. And if you sign up today with a $5 recurring deposit, Acorns will add a $20 bonus to help you begin your investment journey.

Understand what you own

For Buffett, a stock represents a share of an actual business. He looks for companies that can keep generating strong returns over the long term. In other words, the Oracle looks for companies that make something.

If you’re picking individual stocks, start by understanding how a company makes money, what sets it apart from competitors and whether it’s carrying too much debt. And don’t overlook the price you’re paying. Even a good company can be a bad investment if the stock is overpriced.

If that seems like a lot to handle, Moby offers expert research and recommendations to help you identify strong, long-term investments backed by research from former hedge fund analysts.

In four years, and across almost 400 stock picks, Moby says its recommendations have beaten the S&P 500 by almost 12% on average (although past performance cannot guarantee future results). Moby also offers a 30-day money-back guarantee.

Moby’s team spends hundreds of hours sifting through financial news and data to provide you with stock and crypto reports delivered straight to you. Their research keeps you up-to-the-minute on market shifts and can help you reduce the guesswork behind choosing stocks and ETFs.

What’s more, their reports are easy to understand for beginners, so you can become a smarter investor in just five minutes.

Get personalized advice

A low-cost index fund may be a good place to start, but your investment mix should reflect where you are in life. Your age, retirement plans, income needs and tolerance for risk all help determine how much to keep in stocks, bonds and cash.

According to the SEC (6), investors with shorter time horizons may prefer less volatile investments than those who have decades to recover from a downturn.

As retirement gets closer, you’ll also have to think about how to turn those savings into income, manage your tax bill and make your money last.

If you have a portfolio of $250,000 or more, platforms like WiserAdvisor can connect you with vetted professionals who specialize in this kind of planning.

Simply answer a few questions about your savings, retirement timeline and overall investment portfolio. From there, WiserAdvisor reviews its network to match you — for free — with up to three vetted, reputable advisors aligned with your specific needs.
