Buffett’s #1 Move Turned $10K Into $40K in 10 Years
Warren Buffett’s Simple Investment Advice That Turned $10,000 Into $40,000
The Oracle of Omaha’s Golden Rule
When Warren Buffett speaks, the investing world listens. Known as the "Oracle of Omaha," Buffett has a surprisingly simple piece of advice for regular people who want to grow their money in the stock market.
Important Point: Buffett’s top recommendation for most investors isn’t picking individual stocks—it’s buying a low-cost index fund that tracks the S&P 500.
What Is the S&P 500? (ELI5 Explanation)
Imagine a basket containing tiny pieces of the 500 biggest and most successful companies in America—companies like Apple, Microsoft, Amazon, and Google. The S&P 500 is essentially a scorecard that tracks how this entire basket performs as a group.
When you invest in an S&P 500 index fund, you’re instantly buying a small slice of all 500 companies at once.
Buffett’s Specific Pick: The Vanguard S&P 500 ETF (VOO)
Buffett specifically recommends the Vanguard S&P 500 ETF (ticker symbol: VOO). Here’s why this particular fund stands out:
Why VOO Is a Great Choice
- Proven Performance: Turned $10,000 into over $40,000 in the past 10 years (303% total return as of July 28)
- Ultra-Low Fees: Only 0.03% expense ratio (that’s just $3 per year for every $10,000 invested)
- Instant Diversification: One purchase gives you ownership in 500 leading U.S. companies
- Trusted Provider: Vanguard is famous for putting investors first with rock-bottom costs
Why Even Buffett Recommends This "Passive" Approach
You might wonder: If Buffett is such a genius stock picker, why doesn’t he tell everyone to pick stocks like he does?
The Honest Truth About Beating the Market
- Most professionals fail – Even expert fund managers with teams of analysts rarely beat the S&P 500 over long periods
- It takes serious skill and time – Successful stock picking requires deep research, emotional discipline, and constant monitoring
- Regular investors have day jobs – Most people can’t (and shouldn’t) spend 40+ hours a week analyzing companies
Important Point: Buffett admits that for non-professionals, a passive "buy and hold" strategy with index funds often works better than trying to pick winners.
How This Strategy Works in Practice
The "Set It and Forget It" Approach
- Open a brokerage account (like Vanguard, Fidelity, or Schwab)
- Buy shares of VOO (or a similar S&P 500 fund)
- Keep adding money regularly (monthly, quarterly, or whenever you can)
- Don’t panic during market drops – historically, the market always recovers
- Let compound interest work its magic over 10, 20, or 30 years
A Quick Reality Check Before You Buy
The article mentions that Motley Fool’s Stock Advisor service currently has a "10 Best Stocks" list that doesn’t include VOO. Their service has a track record of beating the S&P 500 by 4x, with famous past picks like:
- Netflix (December 2004): $1,000 → $397,081
- Nvidia (April 2005): $1,000 → $1,166,221
This doesn’t mean VOO is a bad choice—it just means there are different investing styles. Buffett’s advice is specifically for people who want a simple, proven, low-stress path.

FAQ
What exactly is an ETF?
An ETF (Exchange-Traded Fund) is like a mutual fund that trades on the stock exchange like a regular stock. You can buy and sell it throughout the day at market prices.
Is 0.03% expense ratio really that good?
Yes! That means for every $10,000 you invest, you pay only $3 per year in fees. Many funds charge 1% ($100/year) or more. Over decades, this difference saves you thousands.
What if the stock market crashes?
The S&P 500 has survived every crash in history—Great Depression, 2008 financial crisis, 2020 pandemic—and always recovered to new highs. The key is not selling during downturns.
Do I need a lot of money to start?
No! Many brokers let you buy fractional shares, so you can start with as little as $1. The important part is starting early and staying consistent.
Is this the only investment I need?
For many people, a diversified portfolio might also include international stocks and bonds. But as Buffett says, an S&P 500 fund alone is a perfectly reasonable core holding for most investors.
Final Thought: Warren Buffett—one of the greatest investors ever—says the best move for most people is also the simplest: buy a low-cost S&P 500 fund like VOO, keep adding to it, and let time do the heavy lifting.
