Stock Crash? Don’t Run! 5 Costly Mistakes 90% of Retail Investors Make
You open your stock app, stare at that ever-growing loss number, and feel your chest tighten. Heart pounding, tossing and turning all night, with ten thousand thoughts flashing through your mind: “I knew I should have sold first.”
This isn’t your fault. It’s a reaction that was engineered into you.
When TV news starts flashing crimson banners screaming “Thousand-Point Plunge” and “Blood in the Streets,” the average retail investor’s biological instinct kicks into full escape mode, rushing to dump their holdings at rock-bottom prices. But here’s something you may have never considered — the terrifying stock crash is precisely the greatest opportunity for ordinary people to翻身 (turn their fortunes around).
Looking back at decades of global financial history, the poor always capitulate at the deepest, most desperate bottoms, while the rich start celebrating when everyone else is panicking. Every great wealth reshuffling happens in that single most panicked moment of the market. Today’s article will fully expose this brutal truth, plus the five things the ultra-wealthy absolutely never do during a crash.

1. Don’t Let Panic Press the Sell Button for You
The first thing the ultra-wealthy absolutely never do during a market crash is blindly dump their positions and clear their portfolios based on raw panic.
Behavioral finance has a classic theory: the pain humans feel from real losses is roughly twice as intense as the pleasure from gains. When hundreds of thousands vanish from your account in an instant, your instinct screams at you to stop the bleeding and get out. But that primitive urge to escape pain immediately is exactly what’s keeping you from ever making serious money in the financial markets.
When facing massive asset shrinkage, what the truly wealthy actually care about is never the short-term price波动 (volatility). The only thing they repeatedly verify is: Has this company’s core competitive edge fundamentally changed?
Take TSMC as an example. When the global macro environment deteriorates, its stock price falls just the same. Impatient retail investors, seeing their cost basis breached, immediately assume the company is finished and sell at a loss in tears. But true veterans of the capital markets do the opposite — they calmly go on a buying spree while the market is spreading panic everywhere.
As long as the fundamentals remain strong, today’s crash is just a clearance sale. If you always let the news media lead you by the nose, panic-selling every time you see a big drop, you’ll forever be the leek getting harvested. Next time you see the Nasdaq plunge in a single day, take a deep breath first. Don’t rush to press that sell button.

2. Stopping Dollar-Cost Averaging Means Personally Killing Compound Interest
The second thing the wealthy never do is casually stop their dollar-cost averaging (DCA) program and interrupt the long-term compounding effect.
Many ordinary office workers start index investing with dreams of early financial freedom, gritting their teeth to set aside part of their salary each month to buy broad-market index ETFs on schedule. But when the market suffers a devastating crash and they watch their hard-earned savings shrink at a suffocating pace day after day, who can stay calm?
These people are overwhelmed by fear, so they decide to stop their contributions — or even redeem everything. They reason internally: “Once the market bottoms out and stabilizes, I’ll start contributing again.” Sounds so rational, so smart, right?
Wrong. This seemingly clever hedging move is exactly the biggest killer of your long-term investment plan and compound interest miracle.
The underlying logic of DCA is to buy more units with the same amount of money when the market is low. When the market is grinding through a long, painful bear market, it’s your golden window to lower your cost basis and accumulate a massive share count. If you stop contributing when prices are cheapest, the expensive筹码 (shares) you bought at bull-market highs really do become trapped positions hanging dangerously high.
Looking back at the S&P 500’s trajectory over the past twenty years, those who stubbornly kept contributing during the 2008 financial crisis saw returns over the following ten-year mega bull market that absolutely crushed those who thought they were smart and jumped off mid-way. The wealthy deeply understand that accumulating assets is a game of time — they will never casually disrupt their original cash flow plan just because of short-term paper losses.

3. Trying to Catch the Bottom Is the World’s Most Expensive Greed
The third thing the wealthy never do is arrogantly try to precisely predict the absolute historical bottom, fantasizing about squeezing out maximum profit.
Everyone has heard of the strategy “buy the dip,” so when the broader market starts pulling back, many people holding cash eagerly prepare to enter and捡便宜 (snag bargains). But those retail investors lacking real-world experience naively fantasize about buying at that exact absolute turning point — the historical low.
They stare at colorful technical charts all day, trying to use various complex indicators to precisely calculate the day the bottom appears. When the index drops 10%, they feel the chips aren’t clean enough yet, wanting to wait and see if it goes lower. When the index actually crashes 20% or even 30%, with bearish news满天飞 (raining from the sky), they get scared instead and don’t dare invest a single cent, terrified of catching a falling knife.
Then after a period of suffocating panic, the market suddenly, without warning, makes a desperate V-shaped rebound and rockets upward. These people who fantasized about精准摸底 (precisely catching the bottom) can only watch helplessly as prices skyrocket, missing even the chance to get on board. Not only do they perfectly miss the optimal bottom-positioning window, but they also endure the psychological torment of being left empty-handed for a long time.
The truly wealthy who have mastered the wealth code absolutely do not play the game of beating the market. When facing broad-based price declines, they use a staged, grid-based left-side trading strategy — pre-setting different drop zones and corresponding capital allocations, and as long as prices enter an attractive valuation range, they strictly follow their mechanical plan to invest idle funds in batches. Admitting you cannot predict the market is, paradoxically, the ultimate survival advantage.

4. Margin Calls Are Handing Your Comeback Chips to the Grim Reaper
The fourth thing the wealthy never do is recklessly add leverage to average down, just to quickly break even.
Facing brutal loss ratios in their stock accounts, many retail investors fall into a gambler’s frenzy, wanting to win it all back in one shot. When a stock they originally liked drops from NT50, many see this as a once-in-a-lifetime翻身 (comeback) opportunity, so they take out personal credit lines or activate their broker’s margin trading function, naively thinking that doubling their capital means even a small反弹 (rebound) will immediately free them from being trapped.
But the cruelty of capital markets lies in this: when the panic of liquidity drought spreads, stocks that were already cheap can become even cheaper. If you’ve borrowed大量 (large amounts of) money to抄底 (bottom-fish) and the price keeps falling irrationally, what you face is no longer simple paper losses. The broker issues warnings when your maintenance margin ratio drops below the standard. If you can’t produce more cash to meet the margin call, your stocks will be force-liquidated.
This惨烈 (tragic) outcome of being forced to sell doesn’t just completely strip you of your only comeback chips — it also saddles you with crushing heavy debt. Wall Street has an old investment saying: “A hundredfold profit made by luck vanishes forever the moment it goes to zero just once.”
The reason the ultra-wealthy survive countless stock crashes is that they place protecting their principal and their right to survive as the absolute top priority. Every dollar they deploy into a bear market is idle cash that won’t affect their normal life — they absolutely never touch interest-bearing leverage tools. As long as you carry no pressure of being forcibly liquidated, you have sufficient底气 (confidence) and patience to ride out the winter with quality assets.

5. Don’t Let Style Drift Destroy Your Ten-Year Master Plan
The fifth thing the wealthy never do is let panic emotions sway them into casually changing their original long-term investment logic.
Many retail investors, when first entering the stock market, solemnly declare themselves坚定的长期价值投资者 (steadfast long-term value investors). They buy the S&P 500 or Nasdaq 100, with the original plan to hold for ten or even twenty years as retirement savings. But when a once-in-a-century crash truly arrives, watching TV pundits constantly amplify doomsday narratives, their convictions instantly collapse.
To seek that tiny bit of可怜 (pitiful) psychological safety, they panic-sell all their broad-market indexes at the deepest point of the crash, then dump all their remaining capital into bonds or gold and other safe-haven assets with可怜的 (pitifully low) yields. This casual changing of investment strategy during a crisis is professionally called “style drift,” and it’s the致命伤 (fatal wound) that causes ordinary people to underperform over the long term.
When you abandon your well-thought-out long-term plan because of short-term market volatility, you’ve already degenerated from an investor into a speculator. By the time the market crisis is resolved and the broader market reopens with报复性上涨 (revenge rally), your capital is still stuck in those sluggish safe-haven assets.
Top-tier investors, before buying any asset, clearly write down on paper the core reasons they’re bullish and buying. As long as the underlying macro logic supporting their buy hasn’t collapsed, no matter how wildly the stock price jumps around in the middle, they absolutely will not sell轻易 (casually). If you originally bought the Nasdaq 100 ETF because you believed in the long-term innovative power of American tech giants, then when recession worries cause the index to plunge, what you should do is carefully verify these tech giants’ R&D progress and market monopoly power. As long as their earning power remains world-class, you have absolutely no reason to change your original intention of holding for the long term.
Conclusion: Zoom Out the Time Frame and Crashes Are Just Small Bumps on the Chart
Actually, as long as you zoom out your investment time frame to ten or even twenty years, every crash and plunge is nothing more than a small wiggle on the chart.
The reason ordinary people are always harvested like fresh green韭菜 (leeks) by the market is that they always use a microscope to examine their short-term losses. But the truly smart and wealthy people use a telescope to审视 (survey) the必然趋势 (inevitable trend) of long-term upward development of human economic progress.
If you want a seat at the next super feast of wealth redistribution, what you most need to do right now is prepare充足的紧急预备金 (ample emergency reserves) ahead of time, and while the market is still狂热 (frenzied), repeatedly temper your psychological resilience and build a trading system that不会被外界噪音干扰 (won’t be disrupted by outside noise). When the entire market is wailing and screaming about the crash, I hope you can recall the content of this article and smile with confidence.
