Market cycles, corrections, crashes, and recoveries
In ninety-nine years of recorded U.S. stock market history, the market has crashed at least once a decade, sometimes more. It has also, at least once a decade, recovered fully and gone on to set new all-time highs. Every major decline in living memory — 1929, 1973, 1987, 2000, 2008, 2020, 2022 — has, with the patience required, eventually been forgotten by the index. Understanding that this is the rule, not the exception, is the single most important lesson for any investor with a horizon longer than a few years. The math is unambiguous; the discipline is hard.
A is a sustained rise of 20% or more from a recent low. A is a sustained 20%+ decline from a recent high. A is a smaller 10-20% decline. Bull markets in U.S. equities since 1950 have averaged about five years and gained roughly 175%. Bear markets have averaged about ten months and lost roughly 36%. The bullish message buried in those averages is that the upside dominates the downside in both magnitude and duration — but only for investors patient enough to wait through the bears.
On a long horizon, drawdowns are statistically inevitable. The historical record (S&P 500 since 1950) shows: a 5%+ pullback happens roughly three times per year on average; a 10%+ correction roughly once per year; a 20%+ bear market roughly once every five-to-seven years; a 30%+ severe bear roughly once a decade; a 50%+ generational drawdown (1929, 1973, 2000-2002, 2008-2009) roughly once every twenty-five-to-forty years. None of these are pathologies. They are the price of admission for the equity returns that compound over decades. An investor with a 30-year horizon should expect to see at least one 50%+ drawdown and several 30%+ drawdowns during their investing lifetime. Planning for them — psychologically and financially — is what separates the investors who hold through and the ones who get shaken out.
The shapes of the drawdowns differ. Some are slow grinds: the dot-com bust took 31 months from peak to trough (March 2000 to October 2002), losing 49%. Others are violent and brief: the COVID crash took 33 days (February to March 2020), losing 34%, before recovering to new all-time highs within five months. Recoveries also vary. The 1929 crash took 25 years to fully recover in price-only terms (without reinvested dividends); with dividends reinvested, recovery came in roughly 15 years. The 2008-09 crisis took roughly 4 years to recover. The COVID crash recovered in months. There is no single 'recovery clock.' But there is a single pattern across all of them: stocks ultimately reflect the productive capacity of the underlying businesses, which over decades grows. As long as that fact holds, drawdowns are temporary and recoveries are eventual.
The single most consequential math problem in long-horizon investing is this: from January 2003 to December 2023, $10,000 invested in the S&P 500 with dividends reinvested grew to roughly $64,000 — a CAGR of about 9.3%. If you missed only the ten best trading days in that 21-year span, your $10,000 grew to about $29,000 — less than half. Miss the best 20 days and you have $18,000. Miss the best 30 and you barely beat inflation. The best days disproportionately cluster INSIDE bear markets — the violent up-days that happen during panic, when investors who sold are still on the sidelines waiting for confirmation that 'things are stabilizing.' The empirical conclusion is uncomfortable but solid: market timing requires being right twice (when to sell, when to re-enter), and getting it wrong even slightly destroys most of your long-run return. Time IN the market beats timing OF the market. The best investors in history have all said this, in different words. They are right.
Every major crash in history was followed by a full recovery and new all-time highs. Explore the major declines and how long each took to recover. The investors who sold at the bottom locked in their losses; the investors who held through eventually saw new highs.
Bear markets are shorter and shallower than the bull markets that follow them, on average. The right takeaway is that drawdowns are common — and recoveries are too. Source: NBER recession dates, S&P 500 historical price data.
| Event | Peak-to-trough | Decline | Duration | Time to recover prior peak |
|---|---|---|---|---|
| 1973-74 Oil Crisis | Jan '73 → Oct '74 | −48% | 21 months | ~69 months |
| 1987 Black Monday | Aug '87 → Dec '87 | −34% | 4 months | ~24 months |
| Dot-com Bust | Mar '00 → Oct '02 | −49% | 31 months | ~56 months |
| Global Financial Crisis | Oct '07 → Mar '09 | −57% | 17 months | ~49 months |
| COVID Crash | Feb '20 → Mar '20 | −34% | 33 days | ~5 months |
| 2022 Inflation Bear | Jan '22 → Oct '22 | −25% | 10 months | ~14 months |
The best market days disproportionately cluster inside bear markets. Sitting out 'until things stabilize' means missing the violent up-days that drive the recovery. The math is structural and unforgiving.
Imagine investing $10,000 in an S&P 500 index fund on January 1, 2008. Within 14 months, the position would have lost about 54% by the market bottom on March 9, 2009. The headlines that month proclaimed the end of capitalism. Newspapers ran graphs of the Dow's intraday lows hourly. Bear Stearns and Lehman were memories; AIG had been seized; General Motors was bankrupt. Every instinct said sell. The investor who held received roughly a five-year wait to recover the original $10,000. By early 2013 they were whole. By 2018 they had doubled. By 2024, sixteen years from the worst possible entry point in modern history, the position was worth roughly $45,000 — a 4.5x return on capital invested at literally the worst moment available. The investor who panic-sold at the March 2009 bottom locked in a permanent ~$5,400 loss and missed the entire recovery. The lesson is not that 2008 was unique. It is that even the worst-timed lump-sum investment in modern equity history compounded into substantial wealth — provided the investor had the discipline to do nothing.

The /macro page tracks indicators historically associated with bull/bear regime shifts: yield curve inversion, unemployment trends, ISM manufacturing, the Sahm Rule recession indicator, and credit spreads. The /alan-scores page reports valuation context (CAPE, equity risk premium) that helps frame whether current prices are stretched or depressed relative to history. For the long-horizon view, every stock and ETF page reports max drawdown over rolling 5/10/20-year windows — useful for understanding the volatility you'd actually have to sit through to capture the historical return. None of these tools predict the next crash; they just provide context for how rare or unrare current conditions are. Phase 2 will swap this prose for an interactive embed of the screen itself.
Three traps collapse repeatedly. First: selling near peaks because 'the market is overvalued.' Even valid valuation concerns generate too many false signals to be the basis for a market-timing strategy; markets stay 'overvalued' for years. Second: failing to re-enter after a sale. Most investors who sell during a downturn say they'll buy back 'when things stabilize' — but stabilization is only visible in retrospect, and the violent up-days happen first. The result is buying back higher than they sold. Third: the 'cash on the sidelines' delusion. Holding cash for an extended period to wait for a crash means giving up several years of compounded equity returns. The math: cash held during a typical 20-year stretch when the market compounds at 9% earns ~1% per year; the foregone wealth on $100,000 over 20 years is roughly $370,000. The crash you're waiting for would have to drop 80%+ for the cash strategy to break even. It almost never does. The honest stance: time in the market dominates timing, by a magnitude that empirical data has confirmed for over a century.
I haven't the faintest idea as to whether stocks will be higher or lower a month — or a year — from now. What is likely, however, is that the market will move higher, perhaps substantially so, well before either sentiment or the economy turn up. So if you wait for the robins, spring will be over.
