A bull market's here — keep DCA-ing?

Q: It's up so much — should I keep investing?

A: Yes. And that "yes" was answered for you by the DCA method from the very start.

What's the first principle of DCA? Giving up market timing. The reason you chose DCA is precisely that you (and almost everyone) can't reliably judge whether now is high or low, whether to buy or wait. You handed that judgment to a fixed discipline — buy on schedule, regardless of price.

So when "it's too high now, hold off" pops into your head in a bull market, what is that? It's the timing impulse coming back. You're trying to pick up again the very judgment you'd decided to abandon. If you think you can judge "it's too high now," then logically you should also trust yourself to judge "it was too low before" — but if you truly had that ability, you shouldn't have chosen DCA in the first place; you'd just time it. Admitting you can't time well, then DCA-ing right through a bull market — that's DCA's internal consistency.

Q: Then aren't I buying at the top?

A: You will indeed buy relatively expensive chips in a bull market; no denying that. But look closely at what DCA actually does across bull and bear.

Because you buy a fixed amount, when the price is high the same money naturally buys fewer units; when the price is low it naturally buys more. This is DCA's automatic mechanism: it inherently has you buy less when it's expensive and more when it's cheap. So yes, you buy high in a bull market, but the quantity was always small; the thing that contributed your large pile of cheap chips was those bear-market days nobody dared to buy.

So the worry about "buying the top in a bull market" is, in fact, automatically diluted by half by DCA's mechanism. You aren't dumping a big sum at the peak; you're just putting in your usual fixed share, and that share buys very little at high prices. Stretch the whole journey out and your average cost is spread across purchases at both ends of bull and bear — far less dire than it looks when you stare at the current high price.

Q: Is there a smarter way?

A: There are two that both count as reasonable, but let me be clear first: they're approaches "better suited to certain people," not "more advanced, makes more money." Don't come at them in a "found the winning trick" mindset.

The first is called mechanically continue: treat bull and bear the same, invest the fixed amount on schedule, think about nothing, adjust nothing. This is the purest DCA. Its virtue is zero decisions and zero emotion — you'll never agonize over a misjudgment, because you made no judgment at all.

The second is called staged profit-taking: you keep DCA-ing as usual, but at the same time, in the bull market, you sell a small portion of your holding in stages by rules set in advance. Note — this is "trim a bit by rule while still investing," not "stop investing to bet on the top." For how exactly to make profit-taking rule-based and how many stages to use, I've written a whole piece on whether DCA should take profit, so I won't expand here.

These two share one premise worth pulling out on its own: neither is predicting the top. Mechanically continuing ignores the top entirely; staged profit-taking only trims bit by bit at preset steps, not betting "this is the very top, sell it all." The moment you start thinking "I can spot whether this is a top, so I'll liquidate at this instant," what you're doing is neither mechanical continuation nor staged trimming — it's a return to pure market timing, the very thing DCA cured you of. The "smarter way," if it's smart at all, is smart only in "replacing judgment with rules," not in "judging more accurately."

Q: Mechanically continue, or take staged profit — which?

A: Depends on what kind of person you are, and whether your money has a clear destination.

If you're the type who gets carried away the moment you start operating manually — sell a little and you want to sell more, watch it keep rising and you regret it, can't help doing more and more — then I'd urge you to honestly pick mechanically continue. For you, any opening for "flexible operation" is dangerous, because it will slowly drag you back into chasing pumps and dumping on drops. Mechanically continuing looks dumb, but it protects exactly the line you're most likely to lose.

If you're the type with strong discipline and a clear plan for the money — say you'd long intended to lock in a portion of this rally for some life goal — then staged profit-taking suits you. It lets you keep accumulating long-term while converting part of the paper gains into money you can actually use, and because it's staged and rule-based, you won't fall into the back-and-forth of "sold too early, sold too late."

Both are fine; the key isn't which you pick, but whether, having picked, you can avoid letting the bull market's emotions rewrite it. The worst case is: you meant to mechanically continue, but as it climbs you can't resist starting to sell and add chaotically; or you set staged profit-taking rules, then in a rush of excitement throw the rules away and liquidate on feel. Whichever you choose, don't change horses midstream.

Q: What's the single worst thing to do in a bull market?

A: Adding leverage, or going all-in with a big sum to chase the rally. These are the two genuinely fatal things in a bull market — ten thousand times worse than "buying high."

The most seductive thing about a bull market is that it makes you feel "this time is different, it'll just keep going up," so your nerve grows and grows. Some start borrowing and using leverage to amplify returns several times; some take the money they'd saved up for staged investing and dump it all in to chase. Both moves tear down DCA's biggest moat with your own hands — "I'm using spare money, I can outlast it, I won't get liquidated."

Remember the public fact mentioned earlier: this market has gone through 70–80% drawdowns historically. The more violently a bull market rises, the more room there often is to fall afterward. Under leverage, a drop of that magnitude is enough to liquidate you at the very bottom and wipe out your capital; going all-in, you stake your whole net worth on the single judgment that "it'll keep rising." Both revive, at the bull market's peak, the gambling instinct DCA worked so hard to cure. For why leverage conflicts utterly with DCA's philosophy, I unpack it in the 5 common DCA mistakes.

Q: So what exactly should I do right now?

A: Most likely — change nothing, keep investing on the original plan.

That answer is boring, but it's right. What you need to do in a bull market isn't to think up some clever operation, but to hold to the plan you set while calm. Amount unchanged, rhythm unchanged, invest when you should. If you'd set staged profit-taking rules before, execute by the rules; if you hadn't, just mechanically continue — that's perfectly fine.

The real test DCA gives you in a bull market isn't "will I buy expensive," but "can I rein in my greed." A bear market tests whether you can withstand fear; a bull market tests whether you can suppress greed — hold both ends and only then has DCA truly run its course in you.

FAQ

Should I keep DCA-ing in a bull market?

Yes. DCA is a strategy that gives up market timing by design; in a bull market you keep buying on schedule, the same money simply buys fewer chips. Stopping DCA means picking timing judgment back up — and timing is exactly what you chose DCA because you couldn't do well.

Won't DCA in a bull market mean buying at the top?

You'll buy relatively expensive chips, but DCA buys less in a bull market and more in a bear market, averaging out cost through discipline over the long run. The fear of buying high is still a wish to time the market, and DCA's premise is admitting you can't call the top.

Should I take profit in a bull market?

You can, but it should be a pre-written, rule-based staged trim, not an ad-hoc gut-feel liquidation. Mechanically continuing to buy and rule-based staged profit-taking are both reasonable; the key is not being driven by emotion.
