After years of relatively smooth sailing in the stock market, U.S. investors are finding themselves in unfamiliar territory as volatility makes a sharp return. The catalyst: a sudden escalation in the conflict in Iran, which has sent ripples through global markets and rattled nerves on Wall Street. According to The Motley Fool, this geopolitical shock has pushed equity volatility to its highest levels of 2026, with the 10-year Treasury yield briefly plummeting to its lowest point since April 2025. For many, the jolt has revived anxieties not seen since the pandemic or the financial crisis before it.
But for seasoned investors—and those willing to learn from history—market pullbacks like these can offer rare opportunities. As The Motley Fool points out, since the 2008-2009 financial crisis, the market has weathered a handful of significant corrections: a 20% drop in 2018, a more than 30% plunge during the COVID-19 bear market, and the drawn-out 2022 downturn, which only resolved at the end of 2023. Each time, the market eventually rebounded, and those who kept their cool often reaped the rewards.
Still, it’s worth remembering that these recoveries haven’t always followed the same script. While large-cap stocks tend to dominate headlines—and portfolios—smaller companies frequently lead the charge during rebounds. Case in point: after the COVID-19 bear market, small caps initially fell further than the S&P 500 at their lowest point. Yet, as the recovery took hold from May to September 2020, small caps and large caps performed similarly before small caps pulled ahead for the next six months. A similar story played out after the financial crisis, with small caps outpacing their larger counterparts for two years following the 2009 market bottom.
Why do small caps often outperform in these cycles? Part of it is the so-called "risk-on" sentiment that emerges when investors sense the worst is over. As confidence returns, money flows into riskier assets, and smaller companies—more nimble and able to recover quickly—can see their fortunes reverse faster than the market’s giants. As The Motley Fool puts it, "It's easier to turn a smaller ship around."
With the latest bout of volatility, many investors are again wondering how best to position themselves for the next recovery. The temptation, according to The Motley Fool, is to chase the hottest sectors or themes—be it tech, AI, or energy—especially as last year’s tech ETFs saw massive net inflows thanks to the artificial intelligence rally. But 2026 has brought a shift: the market has pivoted away from tech and into value, dividend, and cyclical stocks like energy, industrials, and materials, which just happen to be the best performers so far this year.
“This is one of the biggest dangers of chasing specific sectors and recent performance,” the publication warns. Many investors who loaded up on tech and AI stocks are now overweight in one of the worst-performing sectors of the year, missing out on double-digit gains elsewhere. Instead, The Motley Fool advocates for a broader approach: buying the whole market on dips, rather than trying to pick individual winners or sectors.
For that, many turn to the Vanguard Total Stock Market ETF (VTI), which offers exposure to the full spectrum of American equities—large caps, mid-caps, and small caps alike. As the publication explains, "Using a total market ETF brings small-cap exposure into the equation and helps capture some of that extra upside potential. But it doesn't do so in a way that makes it an overly aggressive bet. It's a bit more of a conservative play on the recovery cycle."
There’s also a practical angle. As another The Motley Fool contributor notes, "I generally keep some cash on the sidelines in my portfolio for times just like this. Short-term disruptions can be a chance to buy successful companies at discounted prices. But I don't try to buy individual winners or even specific sectors. I like to buy the whole market on the dip and simply take advantage of lower prices."
This approach, the argument goes, lets investors sidestep the pitfalls of market timing and sector rotation, instead aligning their portfolios with the broader economic narrative. While buying the whole market may not always deliver the biggest gains, it can limit downside risk and provide the best chance to capture the rebound—especially when mid-caps and small-caps, which have underperformed in recent years, are now making an impressive comeback in 2026.
Of course, there’s no one-size-fits-all answer. Some investors prefer the more targeted approach of a small-cap ETF, such as the iShares Core S&P Small Cap ETF or the Vanguard Small-Cap ETF. These funds can offer greater return potential in isolation, but also come with higher risk. The Vanguard Total Stock Market ETF, by contrast, balances the durability and quality of large caps with the growth potential of smaller companies, making it a favored option for those seeking both stability and upside.
It’s not just theory, either. Data backs up the broad-market approach. According to The Motley Fool, their Stock Advisor service has delivered an average return of 949% as of March 8, 2026, compared to the S&P 500’s 190%—a testament to the power of disciplined, long-term investing and the benefits of riding out volatility rather than trying to outsmart it.
That said, even the experts don’t always agree on what’s best right now. As The Motley Fool notes, their analyst team recently identified what they believe are the 10 best stocks for investors to buy at the moment—and the Vanguard Total Stock Market ETF didn’t make the cut. The list included companies they believe could deliver "monster returns" in the coming years, citing past picks like Netflix and Nvidia as examples of the outsized gains possible when you get it right. But for most investors, especially those wary of the risks and uncertainties swirling around the globe, the simplicity and diversification of a total market ETF remain hard to beat.
Looking ahead, the path for U.S. equities remains uncertain. Geopolitical tensions, shifting sector leadership, and the ever-present risk of economic slowdown all loom large. Yet, as history shows, markets have a knack for bouncing back—often led by the very segments that fell the hardest. For investors willing to keep a cool head, stay diversified, and buy when others are fearful, the current volatility might just be another chapter in a long story of resilience and recovery.
In times of turbulence, the wisdom of broad exposure and patience often proves its worth, reminding investors that, even when the seas are rough, those who stay the course are often the ones who reach their destination.
