A Year of Extremes Highlights the Power of Passive Strategies
2025 was not a normal year for stocks. Nvidia (NASDAQ:NVDA | NVDA Price Prediction), the AI leader that dominated returns in prior years, has posted a solid but relatively modest gain of around 41% — a “bad” year by its recent standards. Yet standout performers emerged elsewhere: SanDisk (NASDAQ:SNDK), spun off from Western Digital (NASDAQ:WDC) earlier in the year, became the top S&P 500 stock, soaring almost 600% since its February IPO. Caterpillar (NYSE:CAT) delivered its strongest annual performance in recent memory, rising about 60%. These gains pushed the benchmark index to repeated record highs, and as the year draws to a close, it is up nearly 20% with dividends reinvested.
However, the path was far from smooth. Major disruptions tested investor resolve, although the market repeatedly recovered. For most individuals, timing these swings is difficult, if not impossible. Panic selling during dips often means missing out on the subsequent rebound, while chasing winners risks buying high.
An index fund tracking the S&P 500, such as the SPDR S&P 500 ETF Trust (NYSEARCA:SPY), captured the full upside without requiring constant decisions. This hands-off approach delivered strong results amid volatility, reinforcing why index investing remains the best strategy for most.
The Rollercoaster That Was 2025
The year began on a strong note, extending the 2024 bull market with optimism around the economy’s strength, but volatility struck early and often.
In April, President Trump’s announcement of sweeping tariffs on “Liberation Day” triggered a sharp market reaction. The S&P 500 plunged 12% in the days following, with multi-day drops marking the worst short-term losses since the 2020 pandemic crash. Fears of inflation and trade disruptions dominated headlines. By April 9, tariffs were paused for most countries (except China), allowing a swift recovery. The index turned positive for the year by mid-May and fully reclaimed losses by late June.
October brought another shock: a crypto flash crash on October 10 liquidated over $19 billion in positions, spilling into equities and amplifying risk-off sentiment. Broader concerns, including AI spending debates and policy uncertainty, contributed to periodic pullbacks throughout the year.
Each time, stocks rebounded. The S&P 500 hit multiple record highs in the second half, and is on track to close out December at all-time levels. This pattern — sharp declines followed by higher highs — underscored the market’s resilience but also the emotional toll on active traders.
Why Set-and-Forget Wins for Peace of Mind
These repeated shocks led many investors to sell during perceived crises, only to watch recoveries unfold. Those who exited missed gains or re-entered at higher prices, eroding portfolio returns.
In contrast, a buy-and-hold approach with the SPDR S&P 500 ETF Trust avoided these pitfalls. The S&P 500 delivered total returns (including dividends) of 19% for 2025. While not matching outliers like SanDisk’s extraordinary run or Nvidia’s 41% gain, it provided consistent exposure to the market’s upward march.
Even Nvidia faced pressure: tariff fears caused a temporary 15% plunge, shaking out many individual investors. Staying invested in a broad index eliminated the need to predict such moves. SPDR, as the largest and most liquid S&P 500 ETF, offers low costs and precise tracking. Alternatives like Vanguard S&P 500 Trust (NYSEARCA:VOO) or iShares Core S&P 500 ETF (NYSEARCA:IVV) work similarly, but SPDR’s liquidity makes it a top choice.
The Perils of Stock-Picking
Buy-and-hold can succeed with individual stocks, but risks are higher. iRobot, for example, struggled after its blocked acquisition by Amazon (NASDAQ:AMZN) in 2024, filed for Chapter 11 bankruptcy two weeks ago. It started off 2025 hopeful, but tariffs on imports from Vietnam added $23 million in costs, exacerbating competition from lower-priced rivals. Shares collapsed over 80% after its filing and wiping out equity holders, highlighting the risk of sticking with individual stocks.
Key Takeaway
Index investing spreads risk across hundreds of companies. A bankruptcy like iRobot’s has minimal impact on the S&P 500, while winners like SanDisk and Caterpillar offset laggards and dividends compound quietly.
2025’s volatility — tariff crashes, crypto winters, and recoveries — proved that timing the market is unreliable. Broad exposure through the SPDR S&P 500 ETF Trust captured gains without the stress. In a year of extremes and records, passive indexing delivered reliable results, making the strongest case yet for most investors.
