Markets fall. That's the deal.
As I write this, with data through July 2, 2026, the S&P 500 sits at or near an all-time high. It doesn't feel that way to most people who own stocks. The index dodged an official correction in March 2026, but the average S&P 500 member fell about 21% from its own high at some point this year, according to Charles Schwab's 2026 mid-year outlook. The headline number looked calm while the average member had already been through a fall of about a fifth. So people are asking the old questions again. How bad do declines get? How long do they last? Does the money actually come back?
This page answers those questions with a complete count rather than vibes. We took the S&P 500's full recorded history, back to January 1871, and extracted every decline of 10% or more. There are 32. For each one we measured how deep it went, how long the fall took, and how long the climb back took, all on price. Six of the crises we then measured three different ways, and on all six the answer to the two questions people care about most, how deep and how long, depends on which way you measure. The standard way, price only, ignoring dividends and inflation, says 1929 took 25.0 years to recover. With dividends reinvested and inflation removed, it took 7.2.
Here's the single most useful fact in the whole study, up front: since 1871, the market has spent 82% of all months below some previous high. Being down is not the exception. It is the normal operating condition of owning the S&P 500, and a 10% decline has arrived about every 4.9 years on average. If you internalize that one idea, everything below is detail.
What a drawdown is
Picture the market's chart as a rollercoaster track, but one that climbs over time. Every so often the track hits a new highest point. Then it drops, rattles around below that mark for a while, and eventually climbs past it to set a new record.
A drawdown is that whole round trip: the slide from a record high (the peak) down to the lowest point of the decline (the trough), then the climb back until the market closes above the old record (the recovery). The depth is the percentage lost from peak to trough. The whole time the market is below its old record, we say it is underwater.
One concrete example. On February 19, 2020, the S&P 500 set a record. It lost 33.9% of its value over the next 33 days, the fastest deep decline in the dataset. Then it turned. It took 148 more days to climb back above the February peak, which it did on August 18, 2020. Depth: −33.9%. Time underwater: 181 days, about six months, start to finish.
Here is that episode with every term labeled — this is the shape every drawdown here shares, whether it lasts six months or twenty-five years:
Why measure drawdowns instead of just returns? Because drawdowns are what you actually live through. An average annual return tells you nothing about the two years in the middle where your account was down 40% and you had to decide, every single day, not to sell. Depth and duration put a size and a length on that experience: how far the index fell, and how long it stayed below its old high.
How the numbers were built
Everything on this page comes from one reproducible computation. Here is the whole method, in plain terms:
- Data, 1871 to 1927: Robert Shiller's public S&P Composite dataset, monthly, from January 1871 (1,866 months of prices, dividends, and inflation data through June 2026). One honest caveat: Shiller's monthly prices are the average of each month's daily closes, which smooths out fast crashes and makes early declines look shallower than daily closes would. Each of the six crises measured both ways in section 9 came out shallower on monthly averages, and 1929 is worked through below.
- Data, 1928 onward: daily index closes (Yahoo Finance, ^GSPC), January 3, 1928 through July 2, 2026 (24,741 trading sessions).
- What counts as an episode: every decline of 10% or more from a record high, measured on closing prices. That yields 32 episodes.
- Lens 1, Price: the index level alone, dividends ignored. This is what every chart on TV shows.
- Lens 2, Total return (TR): the index with every dividend reinvested.
- Lens 3, Real total return: total return adjusted for inflation, meaning what your money could actually buy.
The three lenses matter because they disagree, badly, about the biggest question in market history. Section 9 shows how badly. And the monthly-averaging caveat is not hypothetical: the 1929 to 1932 collapse measures −84.76% on monthly-average prices but −86.2% on daily closes. Fast crashes lose some of their violence when you average them.
150 years underwater
This is the study's hero chart: the S&P 500's distance below its record high, every month from 1871 to 2026. You'll recognize the spikes by name (1929, 1973, 2000, 2008), but look at how little of the chart sits on the zero line.
Counted month by month on the price lens, the market was at a new high in only 18.0% of all months since 1871. It spent 82.0% of months below a prior peak, 55.8% of months in a drawdown of at least 10%, 35.1% in a drawdown of at least 20%, and 21.2%, one month in five, down 30% or more from its high.
Dividends soften this picture considerably. Count the same months on total return and the market was at a high 31.0% of the time, with only 31.0% of months in a 10%-plus drawdown. Adjust for inflation and it lands between: at a high 24.4% of months, in a 10%-plus real drawdown 42.0% of the time.
| Lens | Months at a high | Months below a high | In a ≥10% drawdown | In a ≥20% drawdown | In a ≥30% drawdown |
|---|---|---|---|---|---|
| Price only | 18.0% | 82.0% | 55.8% | 35.1% | 21.2% |
| Dividends reinvested | 31.0% | 69.0% | 31.0% | 14.6% | 9.2% |
| Dividends + inflation-adjusted | 24.4% | 75.6% | 42.0% | 26.2% | 14.0% |
Whichever lens you prefer, the conclusion holds. An investor who feels uneasy whenever the market is below its old high has signed up to feel uneasy in 82% of the months since 1871, on the price lens. The high is the anomaly.
One picture makes the proportions concrete. Take all 1,866 months since 1871 and sort each into its drawdown state on the price lens — every square below is 1% of the market's entire recorded history:
Slice the same 155 years decade by decade and the point sharpens: no decade escaped. The calmest stretch in the whole record, the 1990s, still spent 19.7% of its sessions 5% or more below a high. The 1930s and 1940s were almost entirely consumed by the 1929 hole — 92.4% and 99.9% of their observations sat more than 40% below the 1929 peak — and the 2000s spent more than half their sessions 20% or more down as the dot-com bust ran into the financial crisis.

A few things worth pulling out of the table. The deepest decline ever is 1929's −86.2%, and it also holds the record for time underwater: 25.0 years on a price basis (section 9 has a lot more to say about that number). The second-longest is one almost nobody talks about: the peak of June 1881 wasn't durably exceeded until December 1900, 19.5 years later. The fastest fall in the table is 2018's 13-day, −10.2% air pocket, and the most violent single session in the whole daily record belongs to 1987: 19 October closed −20.47%, Black Monday, inside an episode that took 101 days to reach its trough. (The fastest deep decline remains 2020's 33-day, −33.9% collapse.)
Ranked by depth, the twelve worst look like this — note how the 21st century already owns two of the top three slots:
But depth and duration are different orderings, and the difference is instructive. Re-rank the same eight worst crashes by how long they kept an investor underwater and the list scrambles: 2007, the second-deepest decline in history at −56.8%, was also the second-shortest of the eight at 5.5 years, while the −42.1% decline from the 1881 peak — barely deep enough to make the list — held investors down for 19.5 years, second only to 1929. Depth and duration rank differently. The two episodes beginning in 1881 and 1909 stayed underwater far longer than their depth alone would place them.
How long do drawdowns last?
This is the question a scared investor actually wants answered, so let's answer it the way history allows: as a lookup table. Take every completed episode since 1871, group by how deep it went, and read off the median times. (The median is the middle value — half of episodes were faster, half slower.)
| Depth of decline | Episodes | Median days, peak to trough | Median days, trough back to the old high |
|---|---|---|---|
| 10–20% | 15 | 87 | 94 |
| 20–30% | 6 | 338 | 386 |
| 30–40% | 5 | 426 | 639 |
| 40% or more | 6 | 959 | 1,638 |
Read it as a rough map, not a schedule. A garden-variety decline of 10 to 20%, a stronger correction on the ladder below, has typically been a three-month fall and a three-month climb. Unpleasant, then over. A bear market in the 20 to 30% range has typically taken about a year down and a year back. The monsters, 40% and beyond, are a different animal: a median of 959 days falling and 1,638 days (roughly four and a half years) climbing back. Note the sample sizes, though. Six episodes is thin evidence, and your particular crisis is under no obligation to be median.
How often does each kind arrive? Since 1871:
| Depth reached | Times it happened | Average years between |
|---|---|---|
| 10% or more | 32 | 4.9 |
| 20% or more | 17 | 9.1 |
| 30% or more | 11 | 14.1 |
| 50% or more | 2 | 77.7 |
A 10% decline roughly every five years. A 20% bear market roughly every nine. A 30% crash roughly every fourteen. These are not black swans. They are regular visitors that keep no timetable.
One more pattern hides in the durations: recoveries were faster after 1950. Take every episode of 15% or deeper and split the record at 1950. The six early episodes took a median of 1,112 days to recover. The fifteen since 1950: 337 days. The study measures that gap and not its cause. Though 1973 and 2000 prove "shorter" is not "short."
The severity ladder: pullbacks, corrections, and bears
Everything above counts declines of 10% or more, because those are the ones people remember. But most of what an investor actually feels, year to year, never gets that far. Traders sort declines into a standard severity ladder: a pullback is a 3 to 5% dip, a correction 5 to 10%, a stronger correction 10 to 20%, and a bear market 20% or more. So we lowered the sieve from 10% to 3% and re-ran the same episode rule (record close, then trough, then first close back above the record) on the daily closes, which start in 1928. The ladder leaves out the monthly averages before 1928, because averaging smooths fast declines, and this study did not measure how many 3% dips that smoothing hides.
The count jumps from 26 daily-era episodes to 128. Here is the full ladder:
| Tier | Count since 1928 | Arrivals per year | Median depth | Median days, peak to trough | Median days, trough to new high | Median days underwater, total |
|---|---|---|---|---|---|---|
| Pullback (3–5%) | 55 | 0.56 | −4.1% | 15 | 15 | 36 |
| Correction (5–10%) | 47 | 0.48 | −6.5% | 25 | 34 | 65 |
| Stronger correction (10–20%) | 14 | 0.14 | −13.0% | 89 | 89 | 211 |
| Bear market (≥20%) | 12 | 0.12 | −33.7% | 481 | 532 | 764 |
Daily closes, 1928 through 2026-07-02, completed episodes only for the duration medians. One episode was still open at the data end: a pullback from the June 2, 2026 record, −4.5% at its deepest so far.
The scatterplot below is the whole ladder at once — every completed episode as one dot, depth against days from peak to trough, split by tier, with each tier's medians as crosshairs:
Three things worth reading off it. First, the ladder's steps are wildly uneven: each step down roughly doubles the depth but multiplies the time underwater much faster: the median round trip runs 36 days for a pullback, 65 for a correction, 211 for a stronger correction, and 764 for a bear market. A pullback is a nuisance. A bear is a siege. Second, the sub-10% tiers are where most episodes stop: 102 of the 128 episodes (about four out of five) bottomed out before ever reaching "stronger correction" territory. So of the declines since 1928 that reached 3% from a record close, four in five stopped short of 10%, and that is the base rate anyone selling at a 3% dip in fear of a 10% decline is betting against. Third, the dots scatter widely around every crosshair. The fastest pullback needed just 3 days to bottom (June 2007), and the slowest crawled down for 81 days (August 2016). One correction found its floor in 7 days (April 1961), another took 84 (January 1992). And the 10 to 20% tier holds the fastest fall of any decline since 1928 that reached 10%, 13 days to −10.2% in early 2018, right next to a 449-day grind that started in August 1959. The tier tells you the typical script, not the one you'll get.
When does a dip become a crash?
The ladder invites the question every investor asks at −4%: is this the big one? History's answer is a funnel, and the funnel narrows fast. Of the 127 completed episodes of 3% or more, 73 (57.5%) deepened past 5%. Only 26 (20.5%) ever reached 10%. And just 12 — 9.4%, about one in eleven — became bear markets of 20% or more.
The conditional odds are the useful part. A fresh 3% dip had a better-than-even chance (57.5%) of deepening to 5% — dips usually get at least a little worse before they die. But from −5%, only about 36% went on to −10%. The dangerous threshold is −10%: once a decline got that far, it was close to a coin flip (46.2%) whether it kept going to −20%. So the market's own base rates say: a fresh 3% dip usually deepens a little and rarely goes much further, a 10% decline is where the odds of continuing become a coin flip, and a stronger correction is the point where history stops reassuring you.
One more structural asymmetry worth seeing directly: at every tier, the median climb back took at least as long as the median fall, and the widest gap between the two medians is in bear markets. Pullbacks were symmetric (a median 15 days down, 15 back). Corrections took 25 down and 34 back. Bear markets fell for a median 481 days and needed 532 more to reclaim the old high.
One perspective stat to close the ladder: of the 24,741 trading sessions since 1928, only 5.9% ended at a record close, and 85.7% sat somewhere inside a 3%-or-deeper episode, between a peak and the day that peak was finally reclaimed. The dip is not an interruption of the market's normal business. It is the market's normal business.
A methodology note, because you will see different counts elsewhere. Our episodes are anchored to record closing highs, so the entire 1929–1954 stretch counts as one bear market. Studies that reset the peak after a partial recovery — Wall Street Courier's 1928–2023 drawdown analysis is a good example, counting 15 bear markets to our 12 — tally the 1930s and 1940s declines (1937, 1946) as separate bears, because each fell 20%+ from a local high inside that one long underwater period. Neither convention is wrong. Ours keeps every number on this page consistent with the episode table above, and it slightly understates how often declines of every size have been experienced. The same anchoring means a 4% slide that happens inside a still-open deeper episode doesn't count as a new pullback. That is why peak-reset studies report several pullbacks per year while our record-high count shows roughly one every other year.
Every year has a drawdown
Everything above measures declines from record highs, because that's the honest way to count episodes. But there's one more cut of the data, and it's the one that best explains why owning stocks feels harder than the annual-return tables suggest: what happened inside each calendar year. For every year since 1929 we took the year's worst decline from a running peak that resets each January 1. That is the standard "intra-year decline" convention, the peak-reset counting described in the methodology note above. We put it next to that same year's actual close-to-close return.
The two headline numbers pull in opposite directions, and both are true at once. Most years end well: 65 of the 97 complete years since 1929 (67.0%) finished positive on price alone. On total return the sample is longer, running from 1872 to 2025, and 73.4% of those years finished positive. And yet no year got there without a fall along the way: every calendar year in the daily record had an intra-year decline, the shallowest was −2.5% (1995, the calmest year by this measure), and the median year spent its worst moment 13.2% below its own high.
Put those together and you get this study's best single inoculation against panic. A double-digit decline at some point in the year is roughly the norm — it happened in 60 of the 97 years — and 29 of those 60 (48%) still finished the year positive anyway. Twenty-three years managed both a double-digit intra-year drawdown and a double-digit gain. 2020 is the extreme case (−33.9% at the March low, +16.3% by December), and 2023 (−10.3% dip, +24.2% finish) and 2025 (−18.9% dip, +16.4% finish) are the two most recent. The depth of the year's worst moment does carry information — positive years had a median worst decline of −9.3%, negative years −22.6% — but among years whose worst dip landed in the −10% to −20% zone, the year ended up about as often as it ended down. The study pairs each year with its own worst moment; it does not test a rule executed on the day that moment arrived. (2026, through July 2: up 9.3% for the year, with a worst dip of −9.1% — a fairly ordinary year by this lens, however strange it looked from inside.)
The 25-year myth and the hidden 1970s
You have probably heard the scariest statistic in investing: after the 1929 crash, the market took 25 years to recover. It's the number that launched a thousand "stocks are a casino" arguments. It is true for the index price alone: no dividends, no inflation. On the same Shiller monthly data, the dividends-reinvested series recovered in 15.3 years, not 25.0. So we measured six crises three ways.
| Crisis (peak) | Price only | Dividends reinvested | Dividends + inflation-adjusted |
|---|---|---|---|
| 1929 | −84.76%, 25.0 yrs | −81.76%, 15.3 yrs | −76.8%, 7.2 yrs |
| 1973 | −43.35%, 7.5 yrs | −39.16%, 3.5 yrs | −50.06%, 12.0 yrs |
| 2000 | −43.65%, 6.7 yrs | −41.56%, 6.2 yrs | −51.76%, 12.7 yrs |
| 2007 | −50.82%, 5.4 yrs | −49.04%, 4.8 yrs | (no separate real-terms episode — see below) |
| 2020 | −19.09%, 0.6 yrs | −18.92%, 0.5 yrs | −18.86%, 0.6 yrs |
| 2022 | −20.29%, 2.0 yrs | −19.26%, 2.0 yrs | −24.5%, 2.3 yrs |
Monthly resolution (Shiller monthly averages), which is why 2020 shows about −19% here versus −33.9% on daily closes — monthly averaging smooths fast crashes, exactly the caveat from the methodology box.
Start with 1929. On price alone, an investor at the September 1929 peak waited until September 1954: the famous 25 years. But that investor was collecting dividends the whole time. Reinvest them and the wait drops to 15.3 years. Now account for the deflation of the early 1930s — every dollar bought more — and in real purchasing-power terms the 1929 investor was whole by November 1936. Seven point two years. Brutal, but a third of the legend.
Then the lenses flip on you. The bear market of 1973 and 1974 looks moderate on price: down 43.35%, recovered in 7.5 years. But price charts ignore inflation, and the 1970s are where that omission bites. In real terms the damage was −50.06% and the recovery took 12.0 years, until January 1985. The same trap hides in 2000: 6.7 years on price, but 12.7 years (until May 2013) in real terms.
That missing 2007 bar is worth sitting with. Measured in what your money could buy, with dividends reinvested, an investor at the 2000 peak did not get back to even until May 2013. The dot-com bust and the global financial crisis were one 12.7-year episode, not two. Price charts drew two valleys; a real investor lived one.
The honest summary of the three lenses: dividends cut the 1929 recovery from 25.0 years to 15.3 and 1973's from 7.5 to 3.5, took 0.6 years or less off 2000, 2007 and 2020, and none off 2022, while counting dividends and inflation together took the "mild" 1973 episode from 7.5 years on price to 12.0. A drawdown table that shows you only price, which is nearly all of them, misses both of those on the six crises measured here.
The modern era: 2020, 2022, 2025, and 2026
The last six years compressed a remarkable amount of drawdown history into a short window, and no two episodes looked alike.
2020 was the sprint: −33.9% in 33 days, then a new high 148 days after the bottom. Total time underwater, 181 days. An investor who blinked missed the whole thing. An investor who sold at the March 23 low sold 33.9% down, 148 days before the old high came back.
2022 was the grind: a 282-day slide to −25.4% as rates rose, then a 464-day climb. Two full years underwater, with no single dramatic day to point to. In my experience grinds are harder on discipline than crashes, because there's never an obvious moment of capitulation to rally from. That is a read on investor behaviour, and this study measured prices, not behaviour.
2025 was the shock: the index fell 18.9% in 48 days during the weeks of the tariff announcements, just shy of the official bear-market line, and then it was over, with a new high 80 days later. Start to finish, 128 days.
2026, so far, is the strangest of the four: nothing, officially. No 10% episode through July 2. But per Schwab's mid-year outlook, the average index member fell about 21% from its own high during the year while the index avoided even a 10% correction in March. A calm index sat above a much worse average member, which is a good reminder that the S&P 500 is a weighted average of its members rather than a summary of them.
What happened after the worst moments
Here's a question with real money attached: the market has just crossed 20% down, the news is uniformly terrible, and you have cash. What did buying that moment look like, historically?
We found every first time each episode crossed 20% down (17 times since 1871) and 30% down (11 times), then measured total return (dividends reinvested) from that day forward.
| After first crossing… | 1 year later (median) | 3 years | 5 years | 10 years |
|---|---|---|---|---|
| −20% (17 times) | +11.3% | +33.5% | +48.1% | +105.5% |
| −30% (11 times) | +18.1% | +46.3% | +81.2% | +150.6% |
The medians are strongly positive at every horizon, and the deeper cross had the higher median at all four horizons: at 10 years, +150.6% from a −30% cross against +105.5% from a −20% cross. The share of positive outcomes followed that order at 1 and 3 years, but not at 5. From a −20% cross, 64.7% of the 1-year outcomes were positive, 82.4% of 3-year outcomes, 93.8% of 5-year outcomes, and 10 years out, all 15 completed cases were positive. From −30%: 72.7% positive at 1 year, 90.9% at 3 years and again at 5, and every completed 10-year case positive.
Inflation-adjusted, the story softens but survives: the median real total return 10 years after a −20% cross was +69.9%, with 93.3% of cases positive.
Two honest qualifiers before anyone gets excited. First, these are medians around wide outcomes: the 1-year outcome was positive in only 64.7% of the 17 cases, and buying the first −20% cross in 1929 meant riding down much further before any of those gains arrived. Second, "100% positive at 10 years" is a statement about 15 historical cases in one market, not a law of nature. Section 13 is about exactly that.
The cost of panicking, computed
Every drawdown produces the same tug-of-war in an investor's head: this time it won't come back. So we priced the panic. The simulation is simple and deliberately unflattering to the seller: an investor holds the index, sells everything the day the episode first closes 20% down, and buys back in on the day the market recovers its old high — the moment "it's safe again." Their opponent simply holds. Dividends reinvested for both. The wealth math itself runs on monthly data: the crossing and recovery dates are each mapped to the following monthly total-return observation, so the dollar figures below are a monthly-resolution approximation of the day-based story just told.
Across the 17 episodes with a −20% cross and a completed recovery, the median result: the panic seller ends the episode with 71.3% of the holder's wealth. Sell scared, buy back comforted, and the typical single episode costs you about three dollars of every ten. Everything the market gained between the bottom and the old high happened while you were out.
The worst case was, of course, 1929: a seller who bailed at −20% and waited for the (price) recovery kept just 15.6% of what the holder had.
And if someone had repeated the panic-sell playbook at every one of the 17 opportunities since 1871? Compounding all 17 episodes together leaves 0.018% of the holder's wealth (about $2 of every $10,000). Treat that number as an illustration, not a forecast: no real person panic-sells identically for a century and a half. But the direction of the arithmetic is the point. The strategy of leaving during declines and returning at new highs systematically sells low and buys high, and it compounds against you every single time. Selling by rule instead of by fear is a different thing entirely. We tested one of the oldest examples in 40 in, 20 out: the hedge fund trend strategy still in use today.
The mirror image is what buying through the decline looked like, so we ran that test through the deepest decline in this record: invest $100 every month, starting at the exact monthly peak in September 1929, straight through the Great Depression, dividends reinvested.
The result still surprises me, and I built the test. The steady buyer first touched break-even in March 1930, a blip during a bear-market rally that was quickly gone again. The durable answer: from April 1935 on, the plan was above water for good, while the market itself was still deep in the worst drawdown ever recorded. Adjusted for inflation, the durable break-even came in September 1942. The index price, remember, didn't reclaim its 1929 peak until September 1954. The monthly buys kept going all the way down a decline that reached −84.76% on monthly prices, and with dividends reinvested the whole plan was back to even for good two decades before the index got there. The crash was the worst thing that ever happened to a 1929 lump-sum investor. The one who kept buying through the same collapse was above water for good by April 1935. If you want the strategy comparison rather than the history, we've put steady buying head-to-head against timing rules in Dollar Cost Averaging vs Moving Averages.
Japan, the UK, and survivorship bias
Everything above has a hidden assumption baked in, and an honest study has to say it out loud: all of it is measured on the S&P 500, one market with a perfect recovery record in this sample. Nothing in these 155 years of data says another country's index, or the next 155 years of this one, will do the same. "The market always came back" is the record of all 32 qualifying episodes in this one index, not a measured property of equities, and this study did not test how much of that record comes from measuring the index that lasted.
Two sourced comparisons show what the same chart looks like elsewhere.
Japan. The Nikkei 225 closed at an all-time high of 38,915.87 on December 29, 1989. It did not close above that level again until February 22, 2024 — about 34.1 years underwater. An entire working career, start to retirement, inside a single drawdown. That happened in the world's then-second-largest economy, not a frontier market.
The UK. The British market fell about 73% from its May 1972 peak to its December 1974 trough (Monevator; Wikipedia reports the same −73% for the FT 30), and per Wikipedia it did not return to that nominal level until May 1987 — about 15.0 years underwater. The recovery then lasted only months before the October 1987 crash arrived.
So when this page says every S&P 500 decline of 10% or more recovered (and all 32 did), read it precisely. It means: in this one market, all 32 declines of 10% or more since 1871 were reclaimed by July 2, 2026, usually far faster than the folklore claims. It does not mean any one country's index, over any one investor's horizon, is guaranteed to come back. That distinction is an argument for global diversification, and it's the reason the forward-return tables in section 11 describe history rather than promise a floor. If you want the practical version of that argument, we've written a primer on tactical asset allocation: investing across asset classes without market predictions.
Key takeaways
- Being underwater is the market's normal state: 82% of all months since 1871 were spent below a prior high, and only 18% at a new one (price basis). A 10% decline has arrived about every 4.9 years, a 20% bear about every 9.1.
- The deeper the decline, the longer its median fall and its median climb back, in every depth bucket of the completed episodes since 1871. Median 10 to 20% declines resolved in about three months down and three back, while 40%+ collapses took a median of 959 days down and 1,638 back. Recoveries have sped up: median 337 days since 1950, versus 1,112 before.
- Below the 10% line, dips are constant and quick. Since 1928 there were 55 pullbacks (3–5%, median 15 days down and 15 back) and 47 corrections (5–10%, median 25 down and 34 back) — about four of every five declines of 3%+ never reached 10%, and only 5.9% of all daily sessions were record closes.
- Every calendar year had a drawdown — the shallowest since 1928 was 1995's −2.5%, and the median year dipped 13.2% below its own high — yet 67% of those 97 years finished positive on price, and 73.4% of the longer total-return record running 1872 to 2025 finished positive. Of the 60 years with a double-digit intra-year decline, 48% still ended the year up.
- Escalation is rare but non-linear. Of 127 completed 3%+ dips, 57.5% deepened past 5%, 20.5% reached 10%, and 9.4% became bears — but once a decline hit −10%, it was nearly a coin flip (46.2%) whether it went to −20%.
- The 25-year Depression recovery is the price-only answer. With dividends reinvested it was 15.3 years, and in real purchasing power 7.2. The same math cuts the other way in inflationary eras: 1973 was 12.0 real years and 2000 was 12.7, and in real terms the 2000s were one continuous drawdown with no separate 2007 episode.
- Ten years after the first −20% and −30% crossings, every completed case was positive. The median 10-year total return was +105.5% after a −20% cross and +150.6% after a −30% cross. Shorter horizons were less reliable: 1 year after a −20% cross, only 64.7% of cases were positive.
- Panic had a price tag: the median −20% panic-seller who bought back at recovery kept 71.3% of the holder's wealth, and 1929's seller kept 15.6%. Meanwhile $100/month started at the 1929 peak was durably above water by April 1935.
- All of this is the winner's history. Japan spent about 34.1 years underwater from 1989; the UK fell about 73% in 1972–74. The S&P's perfect recovery record describes the S&P, not a law of markets.
