Dollar-Cost Averaging vs Crash Buying – Why I Prefer Consistency Over Intensity

In recent weeks, online discussions on YouTube, forums, and social media have been buzzing with one hot debate: Is disciplined dollar-cost averaging (DCA) through a regular savings plan the smarter path to building wealth, or should investors hoard cash and wait for a major market crash to “buy the dip” all at once?

Let me start by acknowledging that both strategies are solid winners in their own right. Choosing either one puts you far ahead of someone who doesn’t invest at all—leaving their savings vulnerable to long-term inflation which steadily erode the purchasing power. The real question is: Which method suits most retail investors better over the long run?

While crash buying sounds exciting—deploying a large sum at what feels like “bargain” prices—most evidence and practical experience point to disciplined DCA as the superior choice for the majority of everyday investors.

Here are five key reasons why I favour consistency over trying to time intensity.

1. Timing market crashes is extremely difficult—even for professionals

How do we define a “market crash”? Does it include modest corrections in major indices like the S&P 500 of 5%, 10%, or even 20%?

Imagine this: You spot a 10% correction and go full throttle, investing all your hoarded cash. Then the market slides another 15% (or worse). How do you feel—and what do you do—when you’re fully invested with no more capital left to deploy at those deeper lows?

Predicting the exact bottom is notoriously hard. Markets can fall further than expected, or the recovery can begin sooner than anticipated. Historical studies show that market-timing attempts (including waiting for dips) underperform simple, consistent investing most of the time. For instance, analyses of “buy the dip” strategies often reveal they miss rallies, buy too early or too late, and underperform DCA in a majority of historical scenarios (e.g., over 70% in some long-term backtests).

2. DCA reduces emotional stress and regret risk

With over 15 years of investing experience and time spent working in the industry, I’ve learned one hard truth: The theoretical side of investing is actually the simplest part. The real challenge—what separates consistent winners from the rest—lies in mastering emotions, risk management, and proper position sizing.

Crash buying demands steel nerves. You hold large cash reserves during bull markets (while everyone else’s portfolio soars) and then deploy decisively amid panic. Many investors freeze, wait too long, or mistime their entry—leading to suboptimal results.

DCA via a regular savings plan automates everything. You invest a fixed amount monthly, no matter the headlines. This removes emotion from the equation and helps you stay invested through volatility.

3. You capture more of the market's upside over time

Historical data shows that early lump-sum investing (you are in the market sooner) outperforms spreading it out in most periods—simply because markets rise more often than they fall. However, crash buying isn’t true lump-sum; it’s delayed lump-sum after waiting for a drop.

The opportunity cost of holding cash is huge: missing even a few strong months can significantly reduce long-term returns due to compounding. Disciplined DCA keeps your money working steadily, buying more units when prices dip.

4. DCA performs well in prolonged downturns

Studies indicate DCA often softens drawdowns compared to poorly timed lump sums. More importantly, crash buyers frequently miss the bottom entirely—either because the dip isn’t deep enough or fear keeps them sidelined. Consistency wins by ensuring you’re always participating.

The same principle applies beyond investing: Many areas of life reward consistency over short bursts of intensity—relationships, fitness, career growth. Investing is no different.

5. It's simpler, more sustainable, and fits real-life cash flows

Crash buying requires constant monitoring, large cash reserves, and flawless execution—unrealistic for most people who have other priorities in life or are simply too busy with their careers.

Over decades, the “set-it-and-forget-it” approach quietly compounds into serious wealth.

That’s why at FSM, our Regular Savings Plan (RSP) is one of the most popular and widely used features. You can start with as little as S$50, choose from more than 2,000 unit trusts and 300 ETFs, and enjoy 0% fees on RSPs!

Final thoughts

Both DCA and crash buying can work, but for the average retail investor, trying to time crashes introduces too much risk of human error, missed opportunities, and emotional burnout.

Disciplined dollar-cost averaging via a regular plan wins on behaviour, simplicity, and long-term probability. Markets reward time in the market far more than timing the market. Start small, stay consistent, and let compounding do the heavy lifting.

Consistency beats intensity—especially when the latter relies on predicting the unpredictable.
