Some of us might look at super-successful investors such as Warren Buffett and wonder what complex, esoteric things they must know about the stock market and about how to get rich. In many cases, though, these folks got rich in ways that we can, to a great degree, mimic.
For example, a common investing maxim is to "buy and hold." (It's better expressed as "buy to hold," meaning that you intend to be a long-term investor -- as long as the investment remains promising.) Certainly, Warren Buffett believes in that strategy. And if you want to follow suit, Vanguard offers some exchange-traded funds (ETFs) that can help you.

Back in 2016, Buffett offered advice for investors worried about their retirement savings in an interview with CNBC:
I would tell them not to watch the market closely... The money is made in investments by investing... and by owning good companies for long periods of time. If they buy good companies, buy them over time, they're going to do fine 10, 20, 30 years from now.
Warren Buffett is no longer at the helm of the company he built over 60 years, Berkshire Hathaway (NYSE: BRKA) (NYSE: BRKB), having retired at the end of 2025. But much of Berkshire's stock portfolio consists of holdings Buffett bought. Here are a few:
Buffett first bought into Coca-Cola back in 1988. In his letter to shareholders that year, he noted:
We made major purchases [including] Coca Cola. We expect to hold these securities for a long time. In fact, when we own portions of outstanding businesses with outstanding managements, our favorite holding period is forever.
Look at the Berkshire portfolio today, and you'll see that Coke is the third-largest holding, recently worth around $30 billion -- about 9.3% of the company's total value. In 2022, Buffett wrote:
In August 1994 -- yes, 1994 –--Berkshire
completedits seven-year purchase of 400 million shares of Coca-Cola, which we now own. The total cost was $1.3 billion -- then a very meaningful sum at Berkshire. The cash dividend we received from Coke in 1994 was $75 million. By 2022, the dividend had increased to$704million.
Buffett bought into American Express even earlier, in the 1960s. Here's what he said about it in his 2022 letter:
American Express is much the same story. Berkshire's purchases of Amex were essentially completed in 1995 and, coincidentally, also cost $1.3 billion. Annual dividends received from this investment have grown from $41 million to
$302million. Those checks, too, seem highly likely to increase.
American Express was recently Berkshire's second-largest holding, worth nearly $46 billion and representing 22% of the financial services company.
An ETF you might buy and hold is one Buffett has long recommended: the Vanguard S&P 500 ETF (NYSEMKT: VOO). Hang on to it, and you'll own 500 of America's biggest companies. It has averaged about 15% growth annually over the past decade.
It's the kind of investment you can buy expecting to hold for decades. Any components that perform poorly over time will be removed and replaced by growing businesses. It's hard to beat.

Four leading AI models discuss this article
"The article overstates how easily retail investors can replicate Buffett's results by simply buying and holding VOO, ignoring concentration risk and elevated valuations."
The article correctly highlights Buffett's long-term buy-and-hold success with Coke (KO) and American Express (AXP), where dividends compounded dramatically (Coke: $75M in 1994 to $704M in 2022). However, it glosses over that Berkshire's outperformance came from concentrated, high-conviction picks and opportunistic buys, not passive indexing. VOO's ~15% annualized return over the past decade is largely driven by a handful of mega-cap tech names (Magnificent 7), making it far less diversified in practice than advertised. Missing context: S&P 500 forward P/E sits near 22x versus historical 16x median, and Buffett himself has underperformed the index in recent years while holding large cash.
For most retail investors without Buffett's edge, a low-cost Vanguard S&P 500 ETF remains the simplest, evidence-based way to capture long-term equity returns with minimal effort or behavioral mistakes.
"Passive indexing provides market-average returns but ignores the concentrated fundamental risk inherent in the current S&P 500 composition."
The article’s reliance on the 'buy and hold' mantra via the Vanguard S&P 500 ETF (VOO) is a classic survivorship bias trap. While Buffett’s success with Coca-Cola and American Express is legendary, he achieved it through active, concentrated capital allocation, not passive index tracking. The S&P 500 today is heavily skewed toward a handful of technology giants, meaning an investor buying VOO is taking on significant concentration risk in companies with high forward P/E ratios that are susceptible to mean reversion. The article ignores that Buffett’s 'forever' holding period is predicated on deep fundamental analysis and valuation discipline, not the blind, mechanical rebalancing of an index fund.
Passive indexing remains the most statistically robust strategy for retail investors, as active management consistently fails to beat the S&P 500 net of fees over long-term horizons.
"The article markets current S&P 500 valuations as equivalent to Buffett's 1988 entry points, when the multiple expansion that drove past returns is already priced in."
This article conflates two separate theses and obscures a critical timing problem. Yes, Buffett's decades-long holds (KO, AXP) generated exceptional returns — but those were bought at valuations we can't replicate today. Coca-Cola at $1.3B in 1994 was ~15x earnings; today's KO trades 25x forward earnings. The article then pivots to recommending VOO (S&P 500 ETF) as 'the same strategy,' but VOO at current valuations (21x forward P/E, vs. 17x historical average) is materially different from buying Coke in 1988. The 15% annualized return cited for VOO over the past decade is backward-looking and inflated by multiple expansion, not earnings growth. The article never addresses whether today's entry point justifies a 30-year hold.
If VOO's 500 constituents compound earnings at 8-10% annually and you reinvest dividends, even a 21x entry multiple compounds to acceptable long-term returns; Buffett himself has said time in market beats timing the market, and this article's core message — stay invested — is empirically sound across most 20+ year windows.
"A low-cost S&P 500 ETF can be a durable core investment, but the article glosses over succession and regime-change risks that could make a pure buy-and-hold approach underperform in the next decade."
Interesting framing: Buffett’s 'buy and hold' is championed via Coca-Cola and American Express, and Vanguard’s VOO is pitched as the easy path. The piece glosses over Berkshire’s true driver—capital-allocation skill—and even claims Buffett retired in 2025, which isn’t supported publicly. The strongest risk to the one-size-fits-all conclusion is succession risk and potential missteps in future capital allocation. If Amex/Coke lose pricing power or if a new leader misallocates capital, Berkshire could underperform. A low-cost S&P 500 ETF offers diversification and simplicity, but regime shifts, higher rates, and concentration risk in mega-cap leaders mean a pure buy-and-hold vote of confidence isn’t guaranteed to win.
Berkshire’s future capital-allocation ability isn’t guaranteed to remain superior; a new manager or changing business mix could underperform versus a rebalanced index. The article’s retirement claim also undermines credibility and masks succession risk.
"Berkshire's massive cash position now creates a structural drag versus VOO in a lower-rate regime."
ChatGPT's succession-risk flag is valid but incomplete. The real overlooked threat is Berkshire's $189B cash pile earning 5% in T-bills while VOO's earnings yield sits at 4.6%. If rates normalize lower, that cash drag becomes acute. Nobody has addressed how Buffett's own recent underperformance versus VOO already signals the edge is narrowing faster than valuation gaps suggest.
"The S&P 500's inherent index rotation provides a structural risk-management advantage that Berkshire's concentrated, human-led model cannot replicate if its leadership fails."
Grok, your focus on the cash drag is tactical, but misses the strategic point: that $189B is an optionality hedge, not a yield play. Claude is right about valuation, but both of you ignore that 'buy and hold' in VOO is actually a bet on the S&P's ability to rotate winners. If the Magnificent 7 falter, the index self-heals by replacing them. Berkshire lacks that automatic mechanism; its survival depends entirely on human capital, not index mechanics.
"Index self-healing assumes sector replacement at scale; if tech's 30% weight persists but returns compress, VOO's diversification becomes a liability, not a hedge."
Gemini's 'automatic rotation' thesis for VOO needs pressure-testing. The S&P 500's self-healing mechanism assumes new winners emerge at comparable scale and profitability—not guaranteed. If AI capex cycles exhaust returns and no sector replaces tech's 30% weight, the index doesn't magically rebalance upward; it compounds slower. Berkshire's optionality (cash + dealmaking) might actually outperform a structurally weakened index. The real question: does VOO's diversification offset its exposure to a potential multi-year tech normalization?
"Cash reserve is optionality, not a pure drag, and can drive outsized returns via opportunistic bets and buybacks during dislocations."
Responding to Grok's cash-drag concern: Berkshire's cash hoard isn't a pure negative; it acts as optionality to deploy in dislocations, support buybacks, and fund opportunistic bets, which can compound faster than a static cash yield when conditions improve. The risk is a regime of persistently high rates depressing the relative value of waiting, and succession/version-control risk overshadowing the near-term math. In short: optionality matters, but it's not a free pass.
The panel agrees that Buffett's 'buy and hold' strategy is not accurately represented by a passive index like VOO due to its concentration risk and higher valuations. They also highlight Berkshire's cash drag and succession risk as significant concerns.
