Every investor says they can handle volatility—until it actually arrives. Headlines turn negative. Portfolios drop 15 percent, 20 percent, sometimes more. Suddenly, long-term plans feel fragile and the temptation to “wait it out in cash” becomes very real.
The challenge is not predicting downturns. It is managing behaviour during them. Because history is clear: What you do during market declines has far more impact on long-term wealth than the decline itself.
Let’s assume a Canadian investor placed $10,000 into a broad-market ETF tracking a diversified North American index on January 1, 2006. For simplicity, assume an average annual return of approximately 8 percent over the following 20 years—consistent with long-term equity market averages.
If the investor stayed invested for 20 years, that $10,000 would grow to approximately $46,610 by 2026.
That growth includes:
Every one of those events felt catastrophic at the time.
Yet long-term compounding quietly continued.
Now let’s assume the investor panicked during the 2008 downturn.
Markets fell sharply. The investor sold after a 35 percent decline and moved to cash. They waited one year “for things to settle,” then reinvested.
That decision did two things:
Historically, some of the strongest market days occur shortly after steep declines. Missing even a handful of them materially reduces long-term returns.
In this scenario, instead of compounding at 8 percent for 20 years, the investor’s effective long-term return might drop closer to 6 percent due to missed recovery gains.
That same $10,000 would grow to approximately $32,070 over 20 years.
A difference of more than $14,000—on just a $10,000 starting investment.
That gap widens dramatically with larger portfolios.
Now consider the disciplined investor.
Markets fall. Instead of selling, they continue contributing annually using a dollar-cost averaging strategy.
During downturns, they buy more units at lower prices. During recoveries, those additional units compound.
If this investor adds even $2,000 per year for 20 years at an 8 percent average return, the portfolio could grow to over $100,000+.
The downturn becomes an opportunity—not a threat.
We explore this discipline in greater detail in The Power Of Dollar-Cost Averaging.
When markets fall, selling feels responsible. It feels protective. But investing legend Benjamin Graham framed volatility differently:
“The investor’s chief problem—and even his worst enemy—is likely to be himself.”
Short-term declines are emotional. Long-term wealth is mathematical. Warren Buffett put it plainly:
“The stock market is designed to transfer money from the active to the patient.”
And John C. Bogle, founder of Vanguard, reminded investors:
“Time is your friend; impulse is your enemy.”
Market declines test patience. They do not invalidate strategy.
Since 1950, the U.S. stock market has experienced:
Yet broad-market indices have trended upward over decades.
Downturns are temporary. Compounding is permanent…if uninterrupted.
If your portfolio was built based on your risk tolerance and time horizon, market declines do not change that framework.
Rebalancing—not reacting—is the appropriate move.
Down markets are when future returns are often highest.
Continuing systematic investing removes timing risk and allows lower average purchase prices.
Volatility feels worse when observed constantly. Long-term investors benefit from less frequent monitoring.
Broad-market ETFs provide:
If you are invested in globally diversified ETFs, you already own thousands of companies. A recession affects earnings temporarily, not permanently.

Research consistently shows that missing just the 10 best market days over a 20-year period can cut total returns dramatically.
The problem is that those best days often occur within weeks of the worst days.
You cannot selectively avoid downturns without also risking missing recoveries.
This is why staying invested consistently outperforms tactical exits for most investors.
Markets reward discipline, not prediction.
The investor who stays invested through downturns benefits from:
The investor who exits during fear pays a permanent price.
If you want a deeper dive into building a disciplined investing framework, the Wealth Builder Blueprint inside the Northern Nest Egg store outlines a practical system for staying invested through volatility.
For foundational reading, The Little Book of Common Sense Investing by John C. Bogle—featured in our Bookshelf—remains one of the clearest explanations of why index investing works.
A $10,000 investment held through volatility can grow significantly over 20 years. The same investment disrupted by emotional selling may underperform dramatically.
The difference is not intelligence. It is behaviour.
Market declines are uncomfortable. They are also necessary. They reset valuations, clear speculation and create future opportunity.
The long-term investor does not try to predict downturns. They prepare for them.
Stay diversified. Keep costs low. Continue contributing. Let compounding do the work.
History has consistently rewarded that approach.
