Yep, that's fine.
Rebalancing always involves selling the winners and buying the losers; that's totally normal.
In your case, I wouldn't bother with an allocation to EIMI until your portfolio gets bigger, otherwise you're just going to be running up transaction costs to buy it and it won't make any appreciable difference to your portfolio returns. (There's no rule that says what kind of allocation to emerging markets you have to have, incidentally. Smaller investors can get by without any explicit allocation to EMs.)
1) Thank you for the insightful reply. So even though I don't have a bond component to rebalance with, it will still work if I just do it with shares even though they might all be related? Should I explore using cpf to purchase sti if an opportunity for rebalancing occur then?
2) May I know how much is considered big? I started with only STI for the past 3 years and have about 40k in it right now (at 1k/mth, increasing by 100 annually due to pay increment/dividends). I decided to use ibkr as I'm investing 1.2k into iwda monthly. And since ibkr has minimums of 10/mth it shouldn't rack up transaction fees if I buy iwda+eimi every month right?
3) And also since my portfolio is so skewed right now, if sti experience a correction, would I miss an opportunity to buy low since if I follow the ratio, I should theoretically just keep buying iwda+eimi until it matches the ratio?
Sorry for opening more cans of worms lol
