My mum currently has >RM700,000 to be placed in a retirement fund and investment horizon will be around 15 years or more. Vanguard's Target Retirement 2035 Fund $VTTHX has a expense ratio of only 0.14%.

Hey mate, thanks for your suggestion. Where'd you find a FD yielding 3% p.a.? Most FDs are hovering around 2%. An aggressive ETF you say. I personally have got ARKK in my personal portfolio. VTTHX consists of the total stock market (similar to VTI), total international stock market (similar to VXUS), total bond and international bond funds which I believe which adds up to provide similar risk portfolio as what you've suggested. Bonds would definitely be riskier than FD's but with what FDs are yielding now with respect to inflation, I don't think it's worth it? Returns from FDs might even go to negative territory with the inflation in Malaysia. The equity portion of VTTHX would be less riskier compared to that of if I just went with ARKK as it covers the world market. Over a long term period (15 years), the dips should smooth out. Let me know what you think. I'll be calling a few banks to inquire about Amanah Saham too. If that's available I'll probably just put all the funds in there. Any tips on attaining Amanah Saham (fixed priced fund non-bumi ASM) shares would be much appreciated.
