If I use DCA monthly, and buying ES3 and A35 alternatively. On the 12th month which I need to do re-balancing, I will see what's my ES3 and A35 ratio at that point of time and just use the money for that month to buy the laggard to bring the ratio back. Will this be a simplier approach?

Also possible. But that being said (addressing to bluetwinkle as well) I realised you will incur more transaction costs and a bit more admin time doing it monthly.
Based on books that I have read (in particular The Permanent Portfolio), it is always recommended to start a portfolio in one lump sum, rather through DCA, because when you buy the various asset classes at the same time, it will be some kind of snapshot of the portfolio, and come 6 months or 1 year later, a clearer picture can be seen as to who are the under performers (and need to buy more) or vice versa. Performance can be tracked easily as well.
During rebalance, it does not mean you still stick with the amount you started (e.g. I started off with $10,000 - $7,000 (70%) in ES3 and $3,000 (30%) in A35, and play around with this $10,000 only every 6 months or 1 year). At the rebalancing stage, you could add in and grow the capital (using same e.g., after 6 months, it has become $8,000 (80%) ES3 and $2,000 (20%) A35. I then inject in $2,000 more, and make it back to 70-30, so in total I have $12,000, and I buy another $400 for ES3, and $1,600 in A35, making it to $8,400 (70%) in ES3 and $3,600 (30%) in A35).
So, I was thinking, for both of you, maybe you could start with a lump sum first, then with the accumulated cash allocated for investment, rebalance the portfolio 6 months or 1 year later, thus saving the hassle of a monthly purchase.
Thanks. So this plan is more like saving for retirement rather than building income?
I guess my initial idea of how to do this was more like gambling on the system. It felt like one would be able to get more units.
All investment plans start with an aim, usually saving for retirement or financing your kids' education, etc.
Portfolio rebalancing is never about timing the market, but fixing a timing on when to buy in, regardless of the price and market conditions.
