The Equity100 is too US-centric for me. Sure they have IEMG and EFA but how many percent of the portfolio do they make up?
I haven't done the risk analysis etc for them to present the allocation to me, but I'd hazard a guess they represent a very small percentage, and the portfolio likely goes very heavy on CSPX, QQQ and XLP.
Which brings me to my next concern. Why both QQQ AND CSPX? To me this is putting too much weights on FAANG and the usual suspects.
Also, with the Fed printing money like crazy, you'd have to consider USD devaluation in the short term. USD depreciating 10-20% against SGD could shave a significant portion off your returns.
Not saying you shouldn't invest in US market, just make sure you have appropriate exposure to other countries as well.
Anyway, just my 2 cents.
