In just 4 days, the number of investors entering and exiting Nasdaq index DCA collapsed by 17.75%, exposing the most painful truth behind DCA

On July 16, the number of investors in China participating in Nasdaq index DCA was 1,875,093;
by July 20, just a few days later, the participation count had directly fallen to 1,542,277.
In those four days alone, the number of people exiting decreased by 332,816, for an overall decline of 17.75%.

The most worth pondering point is this: during this period, the Nasdaq did not experience a systemic crash. It was neither a deep selloff of valuations like in the 2022 rate-hike cycle, nor a panicked, global wave of liquidations on a financial-crisis scale. Throughout the entire time, it was simply high-level range consolidation, combined with sentiment disturbances caused by small pullbacks in the tech sector and periodic fluctuations in the semiconductor sector.
Yet even this round of not-that-terrible, normal volatility pushed away nearly one-fifth of DCA participants. This is the most real—and most brutal—reality of DCA.

1、Everyone talks about being able to DCA long term—but the real test never comes during a rising market
When the market keeps moving up, everyone can stick with it easily. Your account’s net value keeps refreshing higher day after day, and each DCA deduction feels like a reward for the passage of time—long-termism can be said offhand.
But the turning point that truly filters people always appears when price action stalls and upward momentum slows: the sector keeps churning in and out of ranges, people around you start questioning, and after you buy, you still can’t see profits in the short term. Anxiety and the lack of patience hidden in human nature are exposed instantly. From that moment on, the vast majority waver, hesitate, and finally choose to give up and exit.

2、Most people have a fatal misconception about DCA: DCA is not the same as avoiding losses and volatility
Many people start DCA with the mistaken belief that this strategy can help them avoid losses and smooth out every fluctuation in the market.
But the core value of DCA is only to reduce the pressure of timing for ordinary investors—it cannot completely eliminate market volatility.
If you allocate to the Nasdaq, you must accept how technology stock valuations get pulled back and forth; if you participate in DCA for U.S. stocks, you must endure valuation disturbances brought by U.S. Treasury yields and Fed policy; if you bet on the AI growth track, you will inevitably have to ride the repeated swings driven by semiconductors, earnings reports, and market sentiment.
DCA is never a safe haven from investment storms. It is only a trading system that lets you keep a stable execution pace even when the market is facing waves and turbulence.

3、This time the participation count plummeted, exposing the core problem: many people can’t even accept normal fluctuations
Investors aren’t failing because they can’t withstand an extreme plunge in a bear market. They can’t even tolerate the ordinary, small-range choppiness at high levels. The root cause is that before starting DCA, they never fully clarified the underlying issues:
What is the core goal of my DCA? How long is the planned holding period? What is the maximum drawdown I can tolerate in my account? Can my daily cash flow support uninterrupted deductions for the long term? Do I only believe in long-termism when the market is rising?
If you didn’t think these through clearly in advance, DCA at the end will only become another cycle of chasing after rallies and selling under pressure: when the market is hot, you jump on board out of FOMO; during the consolidation phase, doubt grows in your heart; a small pullback leads you to clear your position and exit; then when a rebound appears later, you’re filled with regret—round after round, you never manage to hold onto your shares.

4、A reliable DCA never requires you to watch participation numbers; you only need to keep your execution rules
Truly long-term DCA investors who get results won’t pay attention to whether the number of people entering and boarding changes, or whether the crowd is still on the train. They only strictly follow the trading rules they set: deduct on fixed dates, invest a fixed amount, execute long term without arbitrary interruption, and review and optimize the plan on a regular basis.
Rules may look simple and dull, but executing them is extremely anti-human. Every day the market will present countless reasons to lure you into disrupting your plan and quitting halfway. Whether you can keep discipline is what ultimately determines the gap in returns.

5、Half of the “excess returns” earned by DCA comes from the index’s long-term rise, and half comes from outlasting the stage when others give up
The core reason long-term DCA widens the return gap is never that you’re better at analysis than others or that your predictions are more accurate. Instead, it’s that while other people leave in a rush due to short-term volatility, interrupt deductions because they lack patience, or choose to give up because they can’t see immediate gains, you still stay in the lane and execute your plan on time.
The compounding dividends over a long cycle are accumulated little by little through countless moments when other people get off the train and you choose to remain steadfast.

6、DCA is definitely not about mindlessly stubborn holding—the prerequisite is picking the right assets and matching them to your position and cash flow
Sticking to DCA doesn’t mean blindly holding with your eyes closed. There are two hard prerequisites you cannot ignore: first, choosing high-quality assets that have long-term growth vitality; second, sizing your position so it strictly matches your own risk tolerance, such that your everyday cash flow can easily cover each period’s deduction.
If you go into it with a heavy allocation from the start, and the volatility of your holdings directly affects normal life—lying awake with anxiety night after night—then that isn’t DCA. That’s you forcibly putting pressure onto your life.
For ordinary people, the right DCA state should be: when the market falls, you can add calmly; when the market rises, you should never add blindly; during sideways consolidation, keep your mind calm; and your investment actions should not interfere with the real-life rhythm at all.

7、This time the DCA participation drop is more like a mirror that reflects human nature
The data tells us clearly: most investors are not defeated by the market’s big drop—they are defeated by their own psychological expectations for short-term volatility. If they can’t even stick through a round of mild consolidation, then once they face a deeper drawdown of 20%, 30%, or even 40% in the future, choosing to abandon the position and exit is almost inevitable.

The hardest part of DCA has never been the buy operation. It’s whether, when the market keeps withholding immediate positive feedback, you are still willing to firmly believe in the long-term plan you set.
