I would say that you are wrong here. Although I get what you are trying to say but just look at it from a different perspective.
According to me, every person who has a stable income, can be low, but still stable, then he can make use of DCA strategy to his benefit.
For example: If a person is earning $500 a month, even if he saves $100 then he can start investing with that amount or even half of that.
The catch is that he will have to regularly invest that amount so that he can leverage DCA.
Regular and consistent purchases, even in small amounts, can indeed be done and are also profitable. The condition is perseverance to stay on the path and do it in the long run, and what becomes more important is to allocate a safe amount. It will help to manage the investment so that it remains protected until the desired target is achieved.
It would be better to distinguish between savings and investments. Manage our finances well first, and then we will see a safe amount for us to allocate to investments with DCA.
I guess you are talking about emergency fund here that we need to accumulate before starting to invest our money in other assets.
Yes, that is definitely mandatory to have as it will help us a lot in case of emergencies and also provides us a stress free mind knowing that we have a spare fund in case things go southwards.
Once we have accumulate that we plan to invest by DCA strategy slowly and steadily over the time to build a robust portfolio.
Set all the priorities first or paying up all the necessary necessities on which after that then this is where you would be considering on having those savings on which you can be able to make those plans when it comes to investment. It all matters about proper money management on this case on which not all might that good when it comes into this aspect but as much as possible on where you should be that mindful into the things that you've been that dealing into. You are the ones will be leading out the actions on which you would be needing up to mind off and consider whether it would be giving out that positive outcome or not. There are those times that you might be that thinking up positively but its always best that you should be that having that kind of versatility on different various conditions that you might be able to encounter.
