Imagine asking the world’s most successful investor which stock you should buy.
You might expect Warren Buffett to reveal a hidden gem—a little-known company poised to soar.
Instead, he keeps pointing people toward something surprisingly simple: a low-cost S&P 500 index fund.
For decades, Buffett has argued that most investors don’t need to pick winning stocks to build wealth. In fact, he believes trying to outperform the market often does more harm than good.
So why does one of history’s greatest stock pickers recommend an investment strategy that doesn’t rely on stock picking at all?
The answer reveals one of the most powerful investing lessons anyone can learn.
Buffett’s Advice Has Been Remarkably Consistent
Buffett built Berkshire Hathaway by identifying outstanding individual businesses — but his advice for everyday investors has stayed simple and steady the entire time. In his 2016 shareholder letter, he put it plainly: “My regular recommendation has been a low-cost S&P 500 index fund.” He’s repeated some version of that message at Berkshire’s annual meetings for years since.
The clearest example shows up in his own estate planning. In his 2013 letter to Berkshire shareholders, Buffett described the instructions he’d written for the trust he’d leave his wife: the large majority in a low-cost S&P 500 index fund, a smaller portion in short-term government bonds, and Vanguard specifically named as his suggested provider. This is a person who spent decades outperforming professional money managers, telling the world that for his own family’s money, a simple index fund would likely do better than most high-fee alternatives.
His reasoning comes down to something fairly unglamorous: over long stretches of time, a large majority of professionally managed funds fail to beat the broader market after fees are factored in. Rather than trying to guess which fund manager or which stock will outperform next, Buffett’s philosophy is that most people are better off simply owning the market as a whole.
Did You Know? Buffett’s advice hasn’t shifted with market trends, new technology sectors, or short-term headlines — and that consistency is arguably part of the lesson itself. The strategy isn’t designed to need constant updating.

Why the Vanguard S&P 500 ETF (VOO) Gets So Much Attention
One fund frequently associated with Buffett’s philosophy is the Vanguard S&P 500 ETF, ticker VOO. It tracks the S&P 500 Index, giving investors exposure to roughly 500 of the largest publicly traded U.S. companies across all major sectors of the economy — everything from technology and healthcare to energy and consumer staples. Its largest current holdings include Nvidia, Microsoft, Apple, Amazon, and Alphabet.
What makes VOO specifically match what Buffett describes as “low-cost” is its expense ratio: just 0.03% annually, on a fund that’s grown to more than $950 billion in assets. On a $10,000 investment, that works out to roughly $3 a year in fees. As individual companies in the index grow, shrink, or fall out of favor, the fund adjusts automatically — no investor decision-making required.
What “Low-Cost, Broad Market” Actually Looks Like
| Factor | VOO’s Approach |
|---|---|
| Expense ratio | 0.03% annually — about $3 per year on a $10,000 investment |
| Diversification | Roughly 500 large U.S. companies across all major sectors |
| Management style | Passive — the index rebalances itself automatically |
| Investor effort required | Minimal — no ongoing stock selection or active trading |
| Historical 10-year average return | Roughly 15% annualized (a historical figure, not a guarantee) |
Warning: A strong historical average return reflects a specific period in market history, not a promise of what comes next. The S&P 500 has gone through significant, sometimes prolonged downturns before, and it will again. The strategy is built on staying invested through those periods — not on avoiding them entirely.

The Power of Low Fees, Explained Simply
One of Buffett’s core investing principles boils down to a single idea: costs matter more than most people assume. Every dollar paid in ongoing management fees is a dollar that’s no longer compounding on your behalf.
Actively managed funds — those run by a manager or team trying to beat the market through stock selection — often charge meaningfully higher annual fees than broad-market index funds. A gap that looks small in a single year, say 1% versus 0.03%, can quietly erode tens of thousands of dollars in returns over several decades once that fee difference compounds alongside the investment itself.
The data behind this isn’t just theoretical, either. Over the past 10 years, more than 85% of large-cap mutual funds available to U.S. investors have underperformed the S&P 500 after fees, and that figure climbs to nearly 90% over 15-year periods, based on S&P Dow Jones Indices data.
Buffett tested this directly in 2007, betting $1 million that a simple Vanguard S&P 500 index fund would outperform a hand-picked selection of five hedge funds over the following decade. By 2017, the index fund had returned 125.8% cumulatively, while the five hedge funds returned between 2.8% and 87.7% each — none of them came close. Buffett donated his winnings to charity.
Why Simplicity Often Wins Over Active Trading
Many new investors assume that successful investing requires constant activity — watching headlines, reacting to news, buying and selling on a regular basis. Buffett’s career argues the opposite. Trading based on short-term news tends to push investors toward buying after prices have already climbed and selling during downturns, which is close to the worst possible timing in both directions.
A broad index fund encourages a different mindset almost by design. Because there’s no single stock to obsess over, the natural approach becomes long-term ownership rather than short-term reaction.
Buffett’s own long-held Berkshire positions demonstrate this in practice: the company first bought Coca-Cola stock in 1988, finished building the position by 1994 for $1.3 billion, and never sold — annual dividend income from that single holding grew from $75 million in 1994 to $704 million by 2022, with the position now worth roughly $30 billion.
Berkshire’s American Express position tells a similar story, growing from $1.3 billion invested in 1995 to a stake worth nearly $46 billion today, with dividends climbing from $41 million to $302 million annually. In both cases, the strategy was simply: buy, hold, and let time do the compounding.
Example: Sarah and Michael
Consider two investors starting with similar amounts of money. Sarah spends years chasing the latest trending tech stocks, buying and selling based on online forums and social media momentum. Some of her picks do well; others don’t, and she spends considerable time and mental energy tracking all of them. Michael, meanwhile, invests the same amount every month into a diversified S&P 500 index fund and rarely checks his account balance in between.
After twenty years, Michael likely hasn’t experienced the thrill of catching the next breakout stock. But by consistently investing, keeping his fees low, and staying out of his own way during downturns, he’s given himself a strong, low-maintenance foundation for long-term wealth — without needing to correctly predict which company would be the next big winner.
Is VOO Right for Everyone?
No investment guarantees positive returns, and VOO is no exception. Because it tracks the broader stock market, its value rises and falls with it — investors should expect volatility, including periods that qualify as bear markets or economic downturns. Historically, diversified equity markets have rewarded investors willing to stay invested over long stretches, but “historically” is doing real work in that sentence; it isn’t a guarantee for any individual investor’s specific timeline.
That’s why financial professionals generally emphasize aligning your investment strategy with your actual time horizon, financial goals, and risk tolerance — not with whatever the market did last week. Buffett’s own will instructions included a 10% allocation to short-term government bonds specifically for stability, a reminder that even his advice isn’t a single all-or-nothing formula for every situation.

What Canadian Investors Should Know
Since Elionyx’s audience spans both U.S. and Canadian readers, it’s worth addressing this directly: Canadian investors can purchase U.S.-listed ETFs like VOO through most major brokerage platforms, including Canadian discount brokerages that offer U.S. dollar trading accounts. However, a few Canada-specific factors are worth understanding before doing so:
- Currency conversion costs. Buying a U.S.-listed ETF with Canadian dollars typically involves a conversion fee, and holding the position long-term means your returns are affected by CAD/USD exchange rate movements, not just the fund’s own performance.
- Withholding tax on U.S. dividends. U.S. dividend income paid to Canadian investors is generally subject to a 15% U.S. withholding tax, though this can often be reduced or recovered depending on the account type — registered accounts like RRSPs are typically treated differently than TFSAs or non-registered accounts under the Canada-U.S. tax treaty.
- Canadian-listed alternatives. Some Canadian investors prefer Canadian-listed ETFs that track the S&P 500 or provide similar U.S. market exposure, which can simplify currency handling and, in some cases, tax treatment — though they may carry a slightly different fee structure.
None of this makes U.S.-listed ETFs like VOO off-limits for Canadian investors — plenty hold them directly — but it’s worth understanding how currency, tax treaty rules, and account type fit into your broader financial plan before deciding between a U.S.-listed and Canadian-listed option.
The Core Lessons Every Investor Can Take From This
You don’t have to predict the next market winner. You don’t need to trade every week, and you don’t need to react to every financial headline that crosses your feed. Buffett’s decades-long message really comes down to a short list of habits:
- Invest consistently, on a regular schedule, rather than trying to time entry points
- Keep investment costs low, and actually check the expense ratio before choosing a fund
- Stay diversified rather than concentrating in a handful of individual stocks
- Think in years and decades, not weeks and months
- Avoid emotional decision-making, especially during downturns
None of these principles are complicated. What makes them hard in practice is that they require patience and discipline in a media environment built to reward the opposite — constant activity, hot takes, and reacting to whatever moved yesterday.
Frequently Asked Questions
What is VOO? VOO is Vanguard’s ETF that tracks the S&P 500 Index, giving investors broad exposure to roughly 500 of the largest U.S. companies through a single low-cost fund.
Why does Warren Buffett recommend index funds instead of picking individual stocks for most investors? Because a large majority of actively managed funds fail to outperform the broader market after fees over long time periods — over 85% of large-cap mutual funds underperformed the S&P 500 over the past decade.
Can beginners invest in VOO? Many beginner investors use broad-market ETFs like VOO because they offer instant diversification without requiring individual stock research. Whether it’s the right fit depends on your personal financial goals, time horizon, and risk tolerance.
Does Buffett personally own VOO? Buffett has consistently recommended low-cost S&P 500 index investing for individual investors, and specifically instructed his own estate to be invested this way. It’s worth distinguishing between his personal, hands-on investment strategy through Berkshire Hathaway and his general advice for everyday individual investors, which are two different things.
Can Canadian investors buy VOO? Yes, through most major brokerage platforms that support U.S.-listed securities, though currency conversion costs and U.S. dividend withholding tax rules are worth understanding first, and some investors may prefer a Canadian-listed alternative for simplicity.
Does a low-cost index fund guarantee good returns? No. Past performance, including any historical average return figures, does not guarantee future results. The S&P 500 has experienced significant downturns before and will again — the strategy relies on staying invested through volatility, not avoiding it.
Is it better to invest a lump sum or invest gradually over time? Both approaches — investing a lump sum immediately or spreading contributions out on a regular schedule (dollar-cost averaging) — have historical merit depending on market conditions and personal comfort with risk. Many long-term investors use regular, automatic contributions specifically to reduce the emotional pressure of trying to time the market.
Final Thoughts
One of the more valuable investing lessons Warren Buffett has ever offered isn’t about finding a hidden stock before anyone else does. It’s about recognizing that successful long-term investing doesn’t have to be complicated, expensive, or constantly managed.
For many investors, consistently contributing to a diversified, low-cost index fund may prove more effective over time than chasing trends or trying to outguess professional money managers — not because it’s exciting, but because patience, discipline, and low costs tend to compound quietly in the background while headlines move on to the next thing.
