What was the rationale behind Endowus’s fund selection and what are the plans in the near future?

They chose to select funds with a relatively low annual total expense ratio (fund fee) of 0.43% to 0.64%. But add their stated annual Endowus management fee and you'll end up mostly well above 1% per year of costs, when the company itself states: "When you look at the math, a difference of just 1% in fees is equivalent to over 240% of lost returns after 30 years."

You can see easily that they did not select the best products for the customer, when you look at the annualized 10 year performance of their 'very aggressive' portfolio, which is is given as 7.36% per year. Compare this to the annual 10 y performance of the Vanguard Total World Stock ETF (VT) of currently 8.57% for an annual fee of only 0.08% (with the depreciation of the SGD versus USD not even calculated in).​​​
