Five Smart Moves When the Market Drops — and Why Doing Nothing Is One of Them

Every market drop produces the same thing: a rush to the exits by people who swore they were in it for the long haul.

I understand the impulse. When you open your brokerage app and the number has moved sharply in the wrong direction, something ancient in your brain interprets that as danger. Not financial danger — actual danger, the kind that makes your heart rate climb and your palms damp. The brain that evolved to flee predators is now managing retirement accounts, and it is not naturally good at it.

What helps, I've found, is knowing what to do before the panic arrives. Decisions made in advance — when you're calm, when the market is ordinary — are almost always better than decisions made while staring at red numbers on a Tuesday morning.

So here are five things worth doing when markets drop. They're not novel. They're not exciting. They work anyway.

Why Panic Selling Almost Always Fails

The math on panic selling is brutal. To benefit from selling during a downturn, you have to be right twice: once on the way out (selling before it falls further) and once on the way back in (buying before it recovers). Professional fund managers with teams of analysts, billions in research, and decades of experience get this wrong more often than they get it right.

The average investor who sells during a downturn doesn't time the re-entry well. They wait for certainty — for the news to turn positive, for the headlines to stop being frightening — and by the time that happens, much of the recovery has already occurred. The S&P 500's best days tend to cluster near its worst days. Miss the ten best trading days in any twenty-year period and your returns are cut roughly in half.

There is also something the financial industry calls the "behavior gap" — the gap between what an investment actually returns and what the average investor in that investment earns, because of buying high and selling low. Studies consistently find this gap runs 1–2% per year. Over thirty years, that difference is enormous.

Panic selling feels like action. It feels like protecting yourself. What it usually does is lock in a loss and guarantee you miss the recovery.

What History Actually Shows

Every bear market in American history has ended. Every single one. The question has never been whether markets recover — they always have — but when, and whether you'll still be in them when they do.

The 2008 financial crisis was the worst downturn since the Great Depression. The S&P 500 fell roughly 57% from its peak. It had fully recovered by 2013, and by 2020 it had more than tripled from the 2009 bottom. The COVID crash of March 2020 wiped out years of gains in a matter of weeks, then recovered in five months — one of the fastest reversals in market history. The dot-com crash took longer: peak to trough to recovery ran about seven years for the S&P 500, though many individual tech names never came back.

The lesson isn't that recoveries are fast. Sometimes they're not. The lesson is that broad, diversified portfolios have always rewarded patience over panic. And that the investors who most reliably come out ahead are, famously, the ones who forgot they had accounts.

Move 1: Do Nothing

This is harder than it sounds. Doing nothing during a downturn means sitting with discomfort, watching numbers fall, and trusting a plan you made when things were calm. It means not calling your broker, not moving to cash, not checking your account four times a day.

If your portfolio was built correctly for your timeline and risk tolerance, a 20% decline is not an emergency. It is the price of admission to the long-term returns that equities have historically delivered. The investor who built a diversified portfolio and did nothing during 2008, 2020, and every smaller correction in between has almost certainly done better than the one who actively managed their response to each.

Before anything else: close the app. Wait 48 hours. Let the instinct to act pass. Most of the time, the best action is the one you don't take.

Move 2: Keep Buying — or Start

If you have regular automatic contributions going into a retirement account, keep them running. This is dollar-cost averaging in its simplest form: the same dollar amount buys more shares when prices are low. A $500 monthly contribution buys twice as many shares at $50 as it does at $100. A sustained downturn is, in the arithmetic that matters, a sale.

If you have extra cash sitting in savings that you won't need for five or more years, a downturn is a reasonable time to deploy some of it — not all at once, but in tranches over several months. Not because you know where the bottom is (nobody does) but because you're buying the same businesses at lower prices.

The psychological trick here is to stop thinking in portfolio value and start thinking in shares owned. Your shares didn't disappear — only their current quoted price changed. The underlying businesses are still operating, still generating cash, still compounding.

Move 3: Rebalance

If you had a target allocation of, say, 80% stocks and 20% bonds, a significant equity downturn may have shifted that to 70/30 or 65/35. Rebalancing means selling the asset that has held up (bonds, in this scenario) and buying the one that has fallen (stocks) — which is exactly the opposite of what emotion tells you to do, and exactly what disciplines you to buy low.

Most advisors suggest rebalancing when an allocation drifts 5 percentage points or more from its target. A major downturn is often the trigger. Some platforms do this automatically; if yours doesn't, a downturn is a good time to check your allocation and adjust.

Rebalancing also enforces a kind of mechanical contrarianism. You can't panic-buy and panic-sell if a rule says you buy what's down and sell what's up.

Move 4: Harvest the Tax Loss

If you hold investments in a taxable account — not an IRA or 401(k) — a downturn creates an opportunity to sell positions at a loss, book that loss for tax purposes, and immediately reinvest in a similar (not identical, due to wash-sale rules) investment. The loss offsets capital gains elsewhere, or up to $3,000 of ordinary income per year, with excess losses carried forward.

This doesn't improve your portfolio's fundamental value — you own roughly the same exposure after the swap. But it creates a tax benefit from a paper loss you were going to sit through anyway. Done carefully, tax-loss harvesting can improve after-tax returns meaningfully over time without changing your investment thesis at all.

The wash-sale rule matters here: you can't sell an investment, claim the loss, and buy back the same investment within 30 days. Selling a total market index fund and buying an S&P 500 index fund is generally fine; selling and immediately rebuying the same fund is not.

Move 5: Review Your Plan — Not Your Portfolio

A downturn is a reasonable time to revisit your financial plan — your timeline, your goals, your actual risk tolerance. If a 20% decline is producing genuine sleep loss, your allocation may be more aggressive than you can psychologically handle, and that's worth knowing. The best allocation isn't the theoretically optimal one; it's the one you can hold through the bad years.

What's not worth reviewing: your specific stock picks. The urge during downturns is to scrutinize every position, find the weakest-looking one, and act on it. That urge produces churn and costs. Review the plan. Leave the holdings alone.

Also worth checking: your emergency fund. If a downturn is causing panic, sometimes it's because the portfolio money is money you might actually need. Three to six months of expenses in a liquid savings account removes the practical urgency from a market dip. You can afford to wait if you're not at risk of needing to sell.

The Boring Investor Advantage

There's a thought experiment in behavioral finance about which investors perform best. The answer that surfaces — sometimes cited as an actual internal study at Fidelity, though the data is disputed — is that the best-performing accounts belong to people who forgot they had them. Whether or not that specific study happened, the underlying principle is real and well-documented: less activity generally produces better outcomes for individual investors.

The most dangerous person in investing isn't the one who doesn't know enough. It's the one who knows just enough to feel confident making moves, but not enough to know which moves actually help. Markets have humbled people with PhDs in economics. The investor who reads one smart article about macro conditions and acts on it is almost certainly going to be wrong in ways they can't see.

Boring works. Low-cost index funds. Automatic contributions. Rebalancing once a year. Doing nothing during downturns. This is the strategy that the evidence consistently supports, and it requires nearly no active decision-making once it's set up.

FAQ

How long do market recoveries typically take?

It varies significantly. The COVID crash recovered in under six months. The 2008 crisis took about four to five years for the S&P 500 to reach previous highs. The dot-com crash took about seven years. The average recovery from bear markets since 1950 has been roughly two to three years. No two downturns are identical, which is part of why timing them is so difficult.

Should I move to cash if I'm close to retirement?

This is a genuine question, and the answer depends on your timeline and income needs. If you're within two years of needing to draw significantly from your portfolio, reducing equity exposure is reasonable — but that adjustment should have happened before a downturn, not during one. The standard approach is to hold one to two years of planned withdrawals in stable assets regardless of market conditions, so you're never forced to sell equities at a loss to meet expenses.

Is it better to invest a lump sum or dollar-cost average during a downturn?

Mathematically, lump-sum investing beats dollar-cost averaging about two-thirds of the time, simply because markets trend upward and money invested earlier has more time in the market. But DCA reduces the regret of putting everything in just before a further decline, and for most people the psychological benefit is worth the small theoretical cost. If DCA gets you to invest when lump-sum would lead you to wait, DCA wins.

Are there investments to avoid during a downturn?

Leveraged ETFs designed to amplify daily market moves are dangerous in volatile markets due to volatility decay — they tend to underperform their stated multiplier over time during turbulent periods. Individual stocks in distressed industries can see permanent losses, not just temporary dips. If you're adding during a downturn, broad diversification is safer than concentrated bets, even if the concentrated bet feels more exciting.

Is there ever a right time to sell during a downturn?

Yes: when your circumstances have changed, not when the market has. If you need the money within the next two to three years, that money should have already been in stable assets. If a position has become too concentrated and a downturn has exposed that risk, trimming it — even at a loss — can make sense. If you've realized your actual risk tolerance is lower than you thought, adjusting your allocation during a recovery (not the trough) is reasonable. Selling because things feel scary is almost never the right time.
