> If you make a salary from your job, dollar cost averaging makes more sense than saving up your salary and then lump sum investing it at some point in time.
Pedantically, many believe that this is not actually DCA.
DCA is a strategy that is a counterpoint to lump sum investing. From that perspective, the common factor required by both strategies is that you actually have a lump sum to invest.
Investing every month as you earn money, assuming you never had enough to do a lump sum isn’t considered DCA from this perspective because there was no alternative to lump sum invest.
I do adhere to this thinking, and I think it would be useful to have a term for each of these three options. Unfortunately nobody’s proposed one that’s stuck for what you’re describing, so an endless debate rages on financial subreddits whenever this comes up.
I only bring this up because whenever people talk about DCA, there is an implicit assumption that they’re discussing from the perspective of their definition of the term. The article is—I assume—using the definition I described. Because yes, saving up your money to invest in one go at the end is categorically the worst option, and silly enough a strategy that it doesn’t often warrant mention or discussion.
