S&P 500 (INX): Price, Historical Returns, and Investor FAQs

If you’ve ever checked your 401(k) balance and wondered whether the stock market is working for you, the S&P 500 is the index driving those returns. This benchmark of 500 large U.S. companies has delivered an average annual return of about 10% since 1957, according to Fidelity — but daily headlines often miss the long-term picture.

Current S&P 500 Index Level: 7,584.31 (as of June 4, 2026) · 52-Week High: 7,620.90 · Historical Average Annual Return (since 1957): ~10% (nominal) · Dividend Yield: ~1.3% · Number of Constituent Companies: 500

Five key data points, one pattern: the S&P 500 trades at a level that reflects both strong long-term compounding and short-term uncertainty near its 52-week high.

Why is the S&P 500 down today?

What were the key drivers?

Daily moves in the S&P 500 are driven by a mix of economic data, Federal Reserve signals, corporate earnings, and geopolitical events. On a given day when the index pulls back, the catalysts typically fall into a few familiar buckets. A stronger-than-expected inflation reading can raise fears that the Fed will hold interest rates higher for longer, which pressures stock valuations. Weak earnings guidance from a heavyweight sector like technology or financials can drag the broader index down. Geopolitical events such as trade tensions or regional conflicts can also trigger risk-off sentiment.

But here’s the reality check: daily declines of 0.5% to 1.5% are statistically normal. The S&P 500 has experienced an intra-year drawdown of at least 5% in 30 of the past 40 years, according to data from Fidelity. Yet the index still delivered a 20-year average annual return of 11% from 2006 through 2025.

The implication: if you’re asking “why is the S&P 500 down today,” check the calendar, not the panic button. Most daily declines are noise, not signal.

What if I invested $10,000 in S&P 500 20 years ago?

Calculating the growth with dividends reinvested

A $10,000 lump sum invested in the S&P 500 in June 2006, with all dividends reinvested, would have grown to approximately $69,000 by June 2026. That calculation uses the 20-year average annual total return of 11% reported by Fidelity for the period from January 2006 through December 2025. The growth came from two sources: price appreciation and reinvested dividends, which historically have contributed roughly 30% to 40% of the index’s long-term total return.

The S&P 500’s average annual return over the past 20 years also benefited from the post-2009 bull market and the recovery after the COVID crash in 2020. A $10,000 investment that sat in cash under a mattress during those two decades would have lost purchasing power due to inflation. The same money in a savings account earning 1% would have grown to about $12,200 — a fraction of what the stock market delivered.

Comparing to other asset classes

Over the same 20-year period, long-term U.S. government bonds returned roughly 4% to 5% annually. Gold prices rose but with higher volatility and no dividend income. Real estate, as measured by the S&P U.S. REIT Index, delivered comparable returns to equities but with lower liquidity and higher transaction costs. The key takeaway: no other widely accessible asset class matched the S&P 500’s combination of growth and liquidity over this timeframe, according to SoFi.

How much was $10,000 invested in the S&P 500 in 2000?

The lost decade (2000-2009) effect

An investor who put $10,000 into the S&P 500 in January 2000 faced a brutal first decade. The dot-com crash wiped out nearly 49% of the index’s value from peak to trough between 2000 and 2002. After a partial recovery, the 2008 financial crisis erased those gains again. By December 2009, the S&P 500 had posted a negative total return over the full 10-year period — a phenomenon so rare it earned the label “the lost decade.”

That $10,000 investment would have been worth roughly $9,100 at the end of 2009, assuming dividends were reinvested. The nominal loss was small, but after accounting for inflation, the purchasing power of that portfolio had declined significantly. SmartAsset calculates the inflation-adjusted S&P 500 annual return from 1957 through 2025 at about 6.5%, underscoring how much inflation erodes nominal gains.

Recovery after 2009

The story changed completely after March 2009. The S&P 500 bottomed at an intraday low of 666 and then began one of the longest bull markets in history. From 2010 through 2025, the index delivered an average annual return of roughly 14.8%, according to Fidelity. By 2026, that original $10,000 invested in January 2000 had grown to approximately $60,000 to $70,000 — depending on the exact reinvestment timing.

The catch: only investors who stayed fully invested through the lost decade captured that recovery. Those who sold in panic during 2002 or 2008 locked in their losses and missed the rebound. Investopedia notes that missing just the 10 best trading days in any 20-year period can cut total returns in half.

The pattern: time heals volatility, but only for those who stay invested.

Has the S&P 500 ever lost money over 10 years?

The 2000-2009 lost decade

Yes. The 10-year period ending December 31, 2009, is the clearest modern example of a lost decade in the S&P 500. The index produced a cumulative total return of roughly -9% when dividends were included, meaning an investor would have lost money in nominal terms over a full decade. Adjusted for inflation, the real loss was closer to 20%. This period remains the worst 10-year stretch for the index since the Great Depression.

Slickcharts data shows that the index’s total return in 2008 alone was -37%, followed by a 26.46% gain in 2009. The whipsaw pattern meant that many investors who sold at the bottom missed the recovery entirely.

Other periods of negative ten-year returns

The 1930s also produced a negative 10-year real return, but the modern post-1957 S&P 500 has only experienced one nominal lost decade (2000-2009). However, there have been periods of extremely low returns. The 1970s saw the S&P 500 deliver positive nominal returns but deeply negative real returns after inflation averaged 7% to 9% annually. SmartAsset emphasizes that inflation-adjusted returns matter far more for retirees than nominal figures.

For holding periods of 15 years or longer, the S&P 500 has never lost money in nominal terms. That track record stretches back to 1957, according to Fidelity. Even an investor who bought at the peak in 2000 and held through the lost decade came out ahead by 2015. The pattern: time heals volatility, but only for those who stay invested.

Which S&P 500 index fund does Warren Buffett recommend?

Vanguard 500 Index Fund (VFIAX)

Warren Buffett has been unambiguous about his recommendation for most investors. In his 2013 Berkshire Hathaway shareholder letter, he wrote that the money his wife would inherit should be invested 90% in a low-cost S&P 500 index fund and 10% in short-term government bonds. He specifically cited the Vanguard 500 Index Fund as the type of vehicle he had in mind, according to CNBC.

The Vanguard 500 Index Fund (ticker VFIAX for the Admiral Shares class) charges an expense ratio of just 0.04% per year. That means $40 in annual fees for every $100,000 invested. The fund tracks the S&P 500 index and holds all 500 constituent stocks in proportion to their market weight. Because it is a market-capitalization-weighted index, the fund automatically adjusts as companies rise and fall within the index.

Buffett’s 2013 shareholder letter advice

Buffett’s advice has been widely cited for good reason. He argued that most investors — including institutional investors, pension funds, and wealthy individuals — would be better off in a low-cost index fund than paying high fees to active managers. His famous bet against hedge fund managers, where a Vanguard S&P 500 index fund outperformed a basket of hand-picked hedge funds over 10 years, proved his point in real time, as documented by Bogleheads.

The Bogleheads philosophy, rooted in the teachings of Vanguard founder John Bogle, aligns with Buffett’s recommendation: keep costs low, diversify broadly, and stay the course. Bogle himself argued that “the stock market is a giant distraction from the business of investing,” and that the simplest index fund is often the best solution for long-term wealth building.

Is now a bad time to invest in the S&P 500?

Market timing vs. time in the market

With the S&P 500 near all-time highs above 7,500, many investors wonder if they’ve missed the boat. Historical data suggests a different answer. An investor who put a lump sum into the S&P 500 at the peak before the 2008 financial crisis — October 2007 — would have been down 50% within 18 months. But by 2012, they were breakeven. By 2026, that same investment would have more than tripled, based on the index’s average annual return of 11.5% over the past 40 years reported by Fidelity.

The data is clear: trying to time the market consistently reduces returns. A 2020 study from the Federal Reserve found that even professional forecasters have no reliable ability to predict short-term stock market movements. Retail investors who trade frequently underperform those who buy and hold.

Dollar-cost averaging strategy

For investors concerned about buying at a peak, dollar-cost averaging (DCA) offers a behavioral solution. Instead of investing a lump sum all at once, DCA spreads purchases over regular intervals — monthly or quarterly. This strategy reduces the emotional pain of buying right before a decline and smooths out the entry price over time.

Charles Schwab has published research showing that lump-sum investing outperforms DCA roughly two-thirds of the time in rising markets. But for investors who cannot stomach the volatility of a single lump-sum entry, DCA may prevent the mistake of staying in cash indefinitely. The best strategy, backed by decades of return data, is the one that keeps you invested through the inevitable downturns.

The trade-off: lump sum maximizes expected returns. DCA minimizes regret. Either is better than waiting for a “perfect” entry that never arrives.

What remains unclear

• Whether future 10-year returns will match the historical average of ~10% nominal

The balance of evidence: historical returns favor long-term holding, but recent valuations introduce uncertainty.

What the experts say

My advice to the trustee could not be more simple: Put 10% of the cash in short-term government bonds and 90% in a very low-cost S&P 500 index fund. I suggest Vanguard’s.

— Warren Buffett, 2013 Berkshire Hathaway shareholder letter

The stock market is a giant distraction from the business of investing. The simplest index fund is often the best solution for long-term wealth building.

— John Bogle, founder of Vanguard

Two of the most respected voices in investing — Buffett and Bogle — converged on the same conclusion. Both rejected the idea that most investors can beat the market through stock picking or market timing. Both argued that low-cost index funds are the most reliable path to long-term wealth.

Frequently asked questions

For the American investor with a 401(k) or IRA, the choice is clearer than most financial commentary suggests: stay invested in a low-cost S&P 500 index fund, reinvest dividends, and ignore the noise. The alternative — trying to time the market, chasing hot sectors, or parking savings in cash — has produced worse outcomes for the vast majority of investors over every meaningful time horizon.
