Can you beat the market?
You have $10,000 in the Dow Jones Industrial Average. The tape is about to start running, one trading day at a time, through a real stretch of market history. The dates are hidden, but the news headlines of the day are not. Periodically, the tape stops and shows you what the newspapers said that morning, and you decide whether to sell everything or hold on.
At the end, the dates are revealed and your result is set against the investor who never touched it. Three named panics, plus a random two-year window from anywhere between 1885 and today. Free, no sign-up, about two minutes a game.
Space pauses. S sells. B buys. Cash earns nothing.
How the game works
The Panic Tape is a market timing game built on a simple question: if you had been holding stocks through a real panic, with only the headlines to go on, would you have held strong, or sold?
Most stock market games hand you a fake portfolio and a live ticker and let you pick stocks. This one does the opposite. It gives you a single $10,000 position in the Dow Jones Industrial Average Index, a historical window you cannot identify, and the same information investors had at the time. That makes it less a trading simulator and more a test of nerve.
1. Pick a panic
The start screen offers three named scenarios and one wildcard: the Panic of 1907, the Great Crash of 1929, the 2008 financial crisis, and Random Era, which picks an unnamed two-year stretch from the full 141-year daily record. Each named scenario runs about two years, and each starts months before the panic, so you sit through the calm first. There is also a tape speed control: one trading week per second, or double that.
2. Watch the tape
The chart draws itself forward one session at a time. You see the day count and your gain or loss since the start, but not the date and not the index level. Below the chart, a ticker strip shows the last dozen daily moves. Your balance updates in real time, and one big button sits underneath it: Sell everything if you are in the market, Buy back in if you are in cash.
Orders fill at the next day’s close, never at the price on the screen. That is a small piece of realism that matters: you cannot sell at the top of a spike you are looking at.
3. Read the headlines
This is the heart of the game. When the tape reaches the morning a headline was printed, it pauses and shows you the outlet and the headline, and nothing else. Some are alarms: a trust company closing its doors, a record one-day loss, a bank seizure. Some are reassurances: a president saying the worst is over, a banker pledging a rescue, a professor declaring that stocks have reached a permanently high plateau.
Every headline is drawn from what was actually printed at the time, and they are deliberately mixed. Some alarms were followed by the worst days of the era. Some were followed by rallies. Some of the reassurances were right, and some are famous now precisely because they were wrong. You will not be able to tell which is which from the card, which is the point.
4. The reveal
When the window ends, everything unmasks: the scenario name, the dates, the Dow’s start, peak, low, and finish. Your final balance sits next to what buy-and-hold would have produced, with a one-line verdict.
Below that, the full chart shows the Dow with dates restored, your money as a dashed line, every day you spent in cash shaded, and each headline pinned to the day it appeared. The stats block tells you how many trades you made, how many days you were out of the market, how many of the period’s ten best days you missed while in cash, and how many of the ten worst you sidestepped.
Then comes the list that most players screenshot: every headline, with what the Dow did over the following month and what you did when you saw it.
5. Share your result
One button downloads a result card with your outcome, the buy-and-hold outcome, and the chart. Play it again, try another panic, or hit Random Era and take your chances with a window nobody has a name for.
The scenarios
The Panic of 1907
The tape starts in July 1906, six months after the Dow’s January 1906 peak, and runs to June 1908. There was no Federal Reserve. The first eighteen months are a slow grind lower under tight money, the insurance losses from the San Francisco earthquake, and a president publicly at war with the trusts. Then, in October 1907, the Knickerbocker Trust Company failed, call money touched 100 percent, and the only lender of last resort in the country turned out to be J. Pierpont Morgan’s library.
The window’s worst session is not in October. It is March 14, 1907, the “rich man’s panic,” when the Dow fell 8.3 percent in a day and then gained 6.7 percent the next. Holding on from July 1906 to June 1908 turned $10,000 into about $8,430, price return only, dividends explicitly excluded. The 1907 tape is the one scenario where a well-timed exit can beat holding, because the recovery had barely begun when the window closes. Whether you can find that exit with a headline in front of you is another matter.

The 1929 Crash, through 1930
The tape runs from the first session of 1929 to the last of 1930. The first nine months are the lure: the Dow rose from 300 to a peak of 381.17 on September 3, and the Federal Reserve’s warnings about speculative loans were followed by new highs. Then Babson, Fisher, Black Thursday, Black Tuesday, and the November 13 low at 198.69.
What most retellings skip is what the tape shows next. From that November low the Dow rallied nearly 50 percent into April 1930, the President said the worst had passed, and it had not. The back half of the window carries the tariff, the drought, the Caldwell collapse, and the failure of the Bank of United States in December 1930. Holding on for the full two years turned $10,000 into about $5,360, price return only, dividends explicitly excluded. The 1932 bottom, 89 percent below the peak, was still eighteen months past the end of the tape.

The 2008 Financial Crisis, through 2009
The tape starts in July 2007, when two Bear Stearns hedge funds were declared nearly worthless and the credit markets began to seize, and runs to the end of 2009. The Dow made its record high of 14,164.53 on October 9, 2007, two months into the credit crunch. Then came a year and a half of rescues that each looked like the bottom: Bear Stearns in March, Fannie and Freddie in September, the bailout bill in October, the bank guarantees, the rate cut to zero.
The actual bottom arrived on a Monday in March 2009 with no rescue attached, at 6,547.05, 54 percent below the peak. By the end of 2009 the Dow had risen 59 percent from that low and was still a quarter below the old high. Holding on for the whole window turned $10,000 into about $7,700, price return only, dividends explicitly excluded. It took until March 2013 to get back to even on a price basis.

Random Era, 1885 to today
Random Era picks a window the same length as the named panics from anywhere in the daily Dow record, which begins in February 1885. You will not know whether you are in 1893 or 1993 until the reveal. Headlines from the game’s library appear whenever the window overlaps one, so a random run might hand you the Northern Pacific corner, the closing of the exchange in 1914, Eisenhower’s heart attack, or the flash crash, or nothing at all.
That last possibility is the honest one. Most two-year stretches of market history are unremarkable, and most of them are up. A player who has learned to sell on the first scary headline finds that the random tape rarely rewards it. If you want to invest in the past and see how you would have done, this is the mode; the reveal links each window’s worst day to its page in This Day in Stock Market History.
Time in the market vs. timing the market: what the data says
The Panic Tape is a game, but the question it asks has been studied to death, and the answers are consistent enough to be worth stating plainly.
Timing has to be right twice. Selling before a decline only pays if you also buy back before the recovery, and the two decisions are made in opposite emotional states. The first feels like relief. The second feels like walking back into a burning building. That asymmetry is why most people who get the first call right get the second one late.
Even bad timing beats waiting. Charles Schwab’s long-running study, Does Market Timing Work?, follows five hypothetical investors over 20-year windows. Perfect timing produced the best result, as it must. But the investor who simply put money in the moment it arrived finished within about 9 percent of perfect, and the investor with the worst possible timing, buying at every peak, still finished far ahead of the one who stayed in cash waiting for a better entry. Across 78 rolling 20-year periods since 1926, the rankings held in 68 of them, and investing immediately never came in last.
Missing the best days is expensive. J.P. Morgan’s annual Guide to Retirement makes the case in one table: over the 20 years to the end of 2024, an investor who missed the S&P 500’s ten best days cut their annualized return roughly in half, and one who missed the best 40 days ended with a negative annualized return (2025 edition). Wells Fargo Investment Institute finds the same shape over the 30 years to mid-2025: missing the best 30 days took the average annual return from 8.4 percent to 2.1 percent (source).
And the best days hide inside the worst stretches. The reason the best-days statistic bites is that the market’s biggest up days cluster in the same weeks as its biggest down days: seven of the S&P 500’s ten best days between 2004 and 2023 came within two weeks of its ten worst. The investor who sells into a panic is, almost by construction, out of the market for the rebound. The Panic Tape reports this directly on the reveal screen: it counts how many of the window’s ten best days you missed while sitting in cash.
The fair caveat. Those best-days figures are total-return numbers with dividends reinvested, and they have been criticized, most sharply by AQR, for being one-sided: an investor who misses the best days usually misses some of the worst days too, and a symmetric analysis is far less frightening. That is a legitimate point, and the game is built to respect it. The reveal shows worst days avoided alongside best days missed, and the game’s own figures are Dow Jones Industrial Average price returns only, dividends explicitly excluded, so they are not directly comparable to the total-return studies above. What the game adds is the part the studies cannot show: what it feels like to make the decision with the headline in front of you.
The real cost of panic selling
Panic selling is not a character flaw. It is a predictable response to loss, and the research on who does it, and what happens next, is more useful than the lectures.
Who freaks out. A 2022 study by researchers at MIT, When Do Investors Freak Out?, examined 653,455 brokerage accounts from 2003 to 2015 and defined a panic sale as liquidating 90 percent or more of an account’s equities within a month. Panic sellers were disproportionately male, over 45, married, and, tellingly, more likely to rate their own investing knowledge as excellent. Panic selling is a confident person’s mistake.
Most panic sellers stay out. The same study found that 30.9 percent of investors who panic-sold never returned to risky assets at all. Of those who did come back, most did so within six months, which in a typical recovery is after the sharpest part of the rebound. The MIT authors’ conclusion is the one The Panic Tape is built around: the damage from panic selling comes less from the sale than from the failure to get back in.
Panic is rarer than it looks. During the COVID crash of early 2020, fewer than one in two hundred Vanguard households moved to an all-cash portfolio (Vanguard research). The median panicker was in their mid-50s with more than a decade of investing experience. Headlines about mass panic are usually about the loud minority; the quiet majority held.
What the game measures. The Panic Tape does not tell you whether you should sell during a crash. It records what happened when you did: the days in cash, the best days missed, and the gap between your result and the investor who did nothing. Over the named panics, the pattern is the one the studies describe. Selling on the frightening headline is easy. Buying back on the reassuring one, when the reassuring one might be Hoover in May 1930, is the part almost nobody gets right.
Frequently asked questions
Is The Panic Tape free? Yes. There is no sign-up, no account, and nothing to download. It runs in your browser on a phone or a computer.
What data does the game use? Daily closing values of the Dow Jones Industrial Average from February 1885 to the present, from Samuel H. Williamson’s series at MeasuringWorth. All figures are price return only, dividends explicitly excluded. For dates before October 1, 1928, the Dow was a 12-stock or 20-stock index, and MeasuringWorth’s spliced series is used.
Are the headlines real? They are drawn from what newspapers of the time printed, shown with the outlet and dated to the morning a reader would first have seen them. Wording has been condensed in some cases to fit the card. None are invented, and none are shown out of order.
Why are the dates hidden? Because everyone knows what happens in October 1929. Hiding the dates and the index level means you are reacting to the shape of the tape and the headlines, which is all anyone had at the time.
Does cash earn interest in the game? No. Cash earns nothing, which slightly favors staying invested. Real cash would have earned a short-term rate, sometimes a meaningful one, as in 1907 or 1981. A future version may add it.
Can you actually beat buy-and-hold in the game? Yes, and in the 1907 scenario it is not even hard, because the window ends before the recovery is complete. The harder question, which the game asks on the reveal screen, is whether you could do it twice. Across the full 1885-to-present record, most two-year windows end higher than they start, and a player who sells reflexively on alarms will lose to holding far more often than not.
What does “missed the best days” mean? The game ranks every trading day in the window by its one-day percentage move. If you were in cash on one of the ten largest up days, you missed it. The reveal also shows how many of the ten worst days you avoided, so you can judge the trade-off yourself.
Is this a stock market simulator? Not in the usual sense. Simulators like paper-trading platforms let you pick stocks with fake money against a live market. The Panic Tape gives you one position in the Dow and one decision, sell or hold, inside a real historical crash. It is closer to a behavioral finance exercise than a trading game.
Is time in the market really better than timing the market? For almost everyone, yes, and the reason is less about returns than about the two decisions timing requires. See the section above for the Schwab, J.P. Morgan, and MIT findings, and the AQR caveat.
Can I use this in a classroom? Yes. See the note for teachers below.
For teachers and classrooms
The Panic Tape works as a financial literacy exercise for high school and college students because it isolates one decision and shows its consequences in two minutes. A simple lesson plan: have students play the 1929 scenario without discussion, then compare result cards; then read the headline list together and ask which ones they sold on and why; then play Random Era. The second round is usually where the lesson lands, because the random tape rarely rewards the reflex the first round taught.
Each scenario can be linked directly (?panic=1907, ?panic=1929, ?panic=2008) so students all play the same window. No accounts are needed and no data is collected.
