Navigating Market Volatility with Confidence

Volatility is the price of admission

Markets do not move in a straight line, and they never have. The U.S. stock market has delivered strong long-term returns precisely because it asks investors to endure stomach-churning drops along the way. On average, stocks experience a correction of 10 percent or more about once a year, and a bear market, a decline of 20 percent or more, every few years. None of that is a malfunction. It is the cost of the returns that build wealth over time. The investors who do well are not the ones who avoid volatility. They are the ones who learn to sit through it.

The mistake that costs more than any crash

The greatest threat to your returns is usually not the market. It is your own reaction to it. When prices fall, the instinct to sell and stop the pain is overpowering, but acting on it locks in losses and, just as damaging, leaves you on the sidelines for the recovery. Morningstar’s annual Mind the Gap study, which compares the returns investors actually earn with the returns of the funds they own, has repeatedly found that the average investor gives up roughly one percentage point a year to poorly timed buying and selling. DALBAR’s long-running research on investor behavior reaches the same uncomfortable conclusion.

The math of recoveries is unforgiving to the impatient. A large share of the market’s best days arrive within days or weeks of the worst ones, often in the middle of a panic. An investor who sells to “wait for clarity” almost always misses those rebounds, because clarity never arrives until prices have already climbed back.

What the last few downturns actually taught us

Recent history offers vivid lessons. In March 2020, as the pandemic took hold, the S&P 500 fell roughly 34 percent in about a month. It felt like the floor had dropped out. Yet the market recovered its losses within months and went on to new highs. Investors who sold in the panic faced an agonizing choice about when to get back in, and many waited too long.

In 2022, both stocks and bonds fell together as inflation surged and interest rates climbed, an unusually painful year that punished the traditional balanced portfolio. Again, the investors who stayed the course recovered, while those who fled to cash often locked in their losses and missed the rebound that followed. The pattern repeats across every downturn on record: the decline feels permanent in the moment, and in hindsight it was a chapter, not the end of the story.

Rebalancing: selling high and buying low on purpose

If reacting emotionally is the problem, having a rule is the solution. Rebalancing is the disciplined practice of returning your portfolio to its target mix. Say you aim for 60 percent stocks and 40 percent bonds. After a strong run, stocks might grow to 70 percent of the portfolio, so you sell some stocks and buy bonds to get back to 60. After a crash, the reverse: you sell some bonds and buy stocks while they are cheap.

Rebalancing forces you to do the very thing your emotions resist, buying low and selling high, without having to predict anything. It is best done on a schedule, once a year, or when your mix drifts past a set threshold, so the decision is mechanical rather than emotional. A simple rebalancing rule has rescued more portfolios than any market forecast ever has.

A plan you wrote down beats a feeling

The simplest defense against panic is a decision made before the panic arrives. Writing down a short investment policy, your target mix, how often you rebalance, and what you will and will not do in a downturn, gives your calm self a way to overrule your frightened self. Automating contributions helps for the same reason: when you invest the same amount every month no matter the headlines, a falling market quietly buys you more shares, and the decision is already made. It also helps to check your accounts less often. The investor who looks once a quarter sees a long climb with occasional dips. The one who checks five times a day sees a roller coaster and feels every lurch. The market is identical in both cases. Only the experience, and the temptation to do something rash, is different.

Why the order of returns matters near retirement

Volatility is an abstraction when you are 40 and adding to your accounts every month. A market drop just means your contributions buy shares on sale. But the picture changes as you approach and enter retirement, because now you are withdrawing rather than adding. A steep decline in the first few years of retirement, while you are selling shares to fund spending, can do lasting damage even if average returns over your retirement are perfectly fine. Planners call this sequence of returns risk.

The defenses are practical. Keep one to two years of spending in cash so you are never forced to sell stocks in a slump. Hold high-quality bonds to draw from during downturns. Be willing to trim spending modestly in a bad year. This is the logic behind a bucket approach to retirement income, covered in Designing Smart Retirement Income Buckets. The structure turns a frightening market into a survivable one.

Why fee-only works when markets get loud

In a downturn, the most valuable thing an advisor can do is often nothing at all: keep you invested, rebalance on schedule, and talk you off the ledge. That counsel earns no commission and sells no product. An advisor paid through commissions, by contrast, may have an incentive to recommend a trade or a new product precisely when staying put is the right call.

You cannot control the market, and you cannot predict it. What you can control is your plan, your costs, your asset mix, and your own behavior when fear is loudest. Build a portfolio you can live with through a 30 percent drop, write down your rules before you need them, and let time do the work. Confidence in volatile markets does not come from certainty about the future. It comes from a plan sturdy enough that the future does not have to cooperate.
