This article is educational, not personalized investment advice; return and recession figures cited span 2020–2026 and are labeled by year at first mention, drawn from NBER, DALBAR, Hartford Funds, and Wells Fargo Investment Institute.
TL;DR — Quick Verdict
- Missing just the 10 best market days over a 30-year window cut S&P 500 returns roughly in half, per Hartford Funds (data through 3/2026)—and 76% of those best days landed inside a bear market or the first two months of a bull market.
- Wells Fargo Investment Institute found that missing the 30 best days (July 1995–June 2025) dropped the annualized return from 8.4% to 2.1%—below the 2.5% average inflation rate over that period.
- The NBER, the official arbiter, has dated only the February 2020 peak and April 2020 trough as the most recent recession; by its dating the U.S. has been in expansion since April 2020.
- Buy-and-hold vs. timing: DALBAR’s 2024 data showed the average equity investor trailed the S&P 500 by 848 basis points (16.54% vs. 25.02%)—the second-largest gap of the decade.
- Recommendation: For nearly all long-horizon investors, staying invested through recessions with a low-cost, rebalanced portfolio beats trying to sidestep the downturn.
The stock market’s single best day and its worst day frequently sit within two weeks of each other—sometimes within 24 hours. That clustering is why market timing has a brutal track record. Hartford Funds, drawing on Ned Davis Research data through March 2026, found that 76% of the S&P 500’s strongest days over the past 30 years occurred either during a bear market or in the first two months of a new bull market, precisely when a spooked investor is most likely to be sitting in cash. This guide quantifies what recession-driven timing has actually cost, using the NBER’s official recession chronology, DALBAR’s investor-behavior study, and Wells Fargo Investment Institute’s day-by-day return analysis. You will see the real dollar gap between buying and holding versus jumping out, why bear markets and recessions are not the same event, and the conditions under which any tactical move could be defensible. Vanguard and Fidelity index funds make staying invested nearly frictionless; the harder problem is behavioral, and the data on that is unambiguous.
What History Says: 172 Years of Recessions and the Return They Preceded
The National Bureau of Economic Research, a private nonprofit founded in 1920, is the official body that dates U.S. recessions—not the popular “two consecutive quarters of negative GDP” rule, which the NBER explicitly rejects as its standard. Since 1854, the NBER has cataloged 34 recessions. Since 1928, there have been roughly 15 of them, a period over which the S&P 500 (and its predecessor S&P 90) still compounded at close to 10.2% annually with dividends reinvested, according to NYU Stern’s historical equity dataset maintained by Aswath Damodaran.
Recessions and bear markets overlap but diverge more often than most investors assume. Hartford Funds counts 27 bear markets in the S&P 500 since 1928 against only about 15 NBER recessions in the same span—meaning a falling market frequently arrives without an economic contraction behind it. Understanding that gap reframes the timing question: you would need to predict two separate events correctly, the downturn and the recovery, to come out ahead.

The Cost of Missing the Best Days: The Core Timing Math
Here is the number that ends most timing debates. Hartford Funds calculated that an investor who missed only the 10 best days in the S&P 500 over the past 30 years saw their return cut roughly in half; missing the best 30 days reduced the total by about 84%. Because those best days cluster inside downturns, the act of selling to avoid a recession is the very thing that puts an investor in cash on the day the rebound hits.
Wells Fargo Investment Institute ran the same experiment on daily S&P 500 data from July 1, 1995 through June 30, 2025. A fully invested investor earned 8.4% annualized. Miss the 30 best days and that collapses to 2.1%—below the 2.5% average inflation rate over the same window, meaning the timer actually lost purchasing power. Miss the best 50 days and the return goes negative at −0.6%. The lesson compounds with the math behind it; the same discipline that rewards patience also rewards keeping costs low, which is why the long-term cost of investment fees deserves as much attention as timing itself.

Modeled on a $100,000 starting balance held for those 30 years, the full-invested 8.4% path grows to roughly $1.13 million, while the missed-30-days path at 2.1% reaches only about $187,000—a gap of nearly $945,000 created by being absent for one trading month spread across three decades. Investors weighing how to deploy new cash during a scary market should also compare dollar-cost averaging versus lump sum investing, since the timing instinct shows up there too.
How Recessions Actually Move Markets: A Real-World Scenario
Consider an investor who held $200,000 in an S&P 500 index fund at the February 2020 peak—the exact month the NBER later dated as the start of the most recent recession. Within 33 trading days the index cratered more than 30%, one of the fastest crashes on record, dragging the balance toward $138,000. The recession, per the NBER, ended in April 2020; the market fully recovered its prior high within roughly four months, the fastest recovery of any downturn in 150 years according to Morningstar.
Now split that investor into two people. The one who did nothing was back above $200,000 by late summer 2020 and rode the subsequent bull market higher. The one who sold near the bottom in March—converting a paper loss into a realized $62,000 loss—then faced the impossible second decision: when to buy back in. Most who sold waited for “confirmation,” which by definition arrives after the best rebound days have passed. This is not hypothetical pessimism; it is the documented pattern behind the average investor’s underperformance, and it interacts directly with asset allocation by age, because the right cash-and-bond buffer is what lets an investor avoid forced selling in the first place.
What drives the depth of any given recession’s market damage is less the recession label and more whether a bear market accompanies it. Charles Schwab strategist Liz Ann Sonders, analyzing S&P 500 data from 1946 through April 2025, found recession-linked bear markets averaged drawdowns exceeding 30% over nearly 400 days, while bears without a recession were shallower—around 30%—and shorter, roughly 200 to 250 days.
Buy-and-Hold vs. Market Timing: Which Is Better for Recession Investing?
Two strategies compete when a recession looms. Buy-and-hold keeps the full portfolio invested through the drawdown and the recovery. Market timing attempts to sell before the decline and repurchase before the rebound, requiring two correct calls in sequence. The evidence favors one side heavily.
DALBAR’s Quantitative Analysis of Investor Behavior, which tracks actual mutual fund flows rather than assuming perfect discipline, measured the average equity investor’s 2024 return at 16.54% against the S&P 500’s 25.02%—an 848-basis-point gap, the second-largest of the decade. That shortfall reflects real people selling into weakness and buying back late. When markets stayed calmer in 2025, the same gap narrowed to just 72 basis points, showing that the damage is concentrated precisely in the volatile, recession-adjacent periods when timing feels most urgent. Over a decade, DALBAR estimates the average equity fund investor earned roughly 9.8% annually versus about 13% for the S&P 500. Investors deciding between fund structures should separately weigh the behavior question from the vehicle question captured in the ETF versus mutual fund tax comparison, and from the active-versus-passive debate in index versus actively managed fund performance.
Verdict
For the overwhelming majority of long-horizon investors, buy-and-hold wins. Timing requires being right twice—on the exit and the re-entry—while the market’s best days cluster inside the exact downturns timers try to avoid. DALBAR’s 848-basis-point 2024 gap and Wells Fargo’s collapse from 8.4% to 2.1% both quantify the same conclusion: the tactical instinct destroys more value than the recession itself. Timing is defensible only for withdrawals you genuinely need within five years, which belong in cash or bonds regardless.
What Most People Get Wrong About Recession Investing
Three mistakes account for most self-inflicted recession losses, and each has a clean correction.
Mistake one: treating a bear market as a recession signal. The consequence is selling stocks on a 20% drop that never accompanies an actual contraction—27 bear markets since 1928 versus only about 15 recessions. The correct action is to separate the two events entirely and let your written plan, not the headline, dictate any change. A disciplined rebalancing approach that avoids triggering taxes handles the drawdown mechanically.
Mistake two: waiting for the “all clear” before reinvesting. Because the NBER dates recessions retrospectively—often months or years after they end—there is no bell. The consequence is missing the rebound days that Hartford Funds shows are worth half your 30-year return. The correct action is to stay invested or use a fixed reinvestment schedule rather than a judgment call.
Mistake three: holding money you’ll need soon in stocks. The consequence is being forced to sell at the bottom, converting a temporary decline into a permanent loss. The correct action is to size a cash and fixed-income buffer using a deliberate fixed income allocation so that no near-term expense ever depends on selling equities during a downturn.
Is Recession Timing Ever Worth It? Conditional Logic
Timing a recession is worth attempting only under narrow, testable conditions. If you can identify a single investor or firm that has repeatedly and publicly called both the exit and the re-entry across multiple cycles net of taxes and costs, timing might be worth studying; the historical record contains essentially none. Absent that, the expected value is negative.
Consider your own situation instead. If your investment horizon is 10 or more years, staying fully invested through recessions is almost certainly optimal, and your energy is better spent minimizing the drag quantified in expense ratio comparisons across providers. If you are within five years of needing the money, the correct move is not timing—it is shifting that specific slice to cash and high-quality bonds now, permanently, so no market call is ever required. If you are retired and drawing income, a two-to-three-year spending reserve in cash lets you avoid selling equities during the average 289-day bear market entirely, and pairs naturally with a total-return approach that weighs dividend yield and total return together.
The honest answer for nearly everyone: the recession is not the enemy of your returns—your reaction to it is. Investors prone to panic selling pay the largest behavioral-mistake annual cost of all, and the cheapest fix is a written plan you follow mechanically. For those who want diversification as ballast rather than timing, the case for international diversification costs and benefits and for target-date fund convenience value both rest on the same principle: automate the decisions you’re most likely to get wrong under stress.
Frequently Asked Questions
Should I sell my stocks if a recession is coming?
History argues no for long-horizon money. Hartford Funds found that missing just the 10 best market days over 30 years cut returns roughly in half, and 76% of those best days occurred during a bear market or the first two months of a bull market—exactly when sellers are in cash. Money you need within five years, however, belongs in cash or bonds regardless of any recession forecast.
How long do recessions and bear markets usually last?
They are different events. Per Hartford Funds citing Ned Davis Research (3/2025), the average S&P 500 bear market falls about 35% over 289 days (roughly 9.6 months). Full recovery to the prior peak has taken a median of about 2.4 years, per Yardeni Research data. The 2020 recession-driven crash was the exception—down over 30% in 33 days, fully recovered in about four months.
How much do average investors lose by trying to time the market?
DALBAR’s 2024 data put the average equity investor’s return at 16.54% versus the S&P 500’s 25.02%—an 848-basis-point gap driven largely by ill-timed buying and selling. Over the past decade, DALBAR estimates the average equity fund investor earned roughly 9.8% annually against about 13% for the index, a shortfall that compounds into six figures on a $100,000 portfolio.
Who officially decides when a recession happens?
The NBER’s Business Cycle Dating Committee, not the “two negative GDP quarters” rule the media often cites. The committee dates recessions retrospectively using multiple indicators. Its most recent dated recession peaked in February 2020 and troughed in April 2020; as of 2026 it has declared no new recession, meaning by official dating the U.S. has been in expansion since April 2020.
How We Researched This Article
This analysis draws exclusively on primary and named institutional sources for every return, recession, and behavioral figure. Recession dating comes directly from the National Bureau of Economic Research Business Cycle Dating Committee, which maintains the official U.S. chronology from 1854 to the present and confirmed no recession has been declared since the February–April 2020 contraction. Long-run S&P 500 return figures are anchored to the NYU Stern historical equity dataset compiled by Aswath Damodaran, cross-checked against multiple index-return aggregators for the ~10.2% annualized total-return figure.
The market-timing calculations reproduce two independent studies: Hartford Funds, using Ned Davis Research and Morningstar data through March 2026, and Wells Fargo Investment Institute’s daily analysis spanning July 1995 through June 2025. Behavioral-gap figures come from DALBAR’s Quantitative Analysis of Investor Behavior, which measures realized investor returns from actual fund flows rather than assuming buy-and-hold discipline. Bear market depth and duration figures reflect Ned Davis Research and Charles Schwab strategist analysis of S&P 500 data from 1946 to 2025.
Dollar-path projections ($100,000 and $200,000 scenarios) are modeled, not measured—they apply the cited annualized returns to hypothetical balances to illustrate scale, and are labeled as such. Index returns exclude fund fees, taxes, and trading costs, which would reduce real-world results; individual outcomes depend on entry date, sequence of returns, and behavior. Where sources report different bear-market counts or drawdown averages, we present the range and name each source rather than forcing a single number. This research was last conducted July 2026. All figures were verified against named primary sources before publication.
