What are better investment options to AIA Pro Achiever for someone with limited investment knowledge, no time to monitor funds, looking at 10-15 years investment horizon, targeting returns of 5%?

just do a pure investment and avoid insurance companies investment plans if possible. it's true, fees are the worst. now it may seem like it's a good deal but tbh your money shouldn't be held up just bc you want to terminate early.. anyway you can start an account with poems for little to no charge and if you're worried about monitoring the funds, i suggest you pick a diversified portfolio of different industries you are comfortable with and at least know what the heck is it about. if all come to nought, just save up, cash is king haha you can top up your cpf or you can buy lump sum retirement plan which has pretty good returns depending on what is your needs. trust me, it sucks when you put money into whatever and years after, it's still depreciating, you are better off saving that money lols

Forget ILPs or unit trusts, as fees are horrendous and performance of funds can be uninspiring. If you just want a hands off investment method with minimum input on your end, look into what Andrew Hallam discussed in his book millionaire teacher - couch potato strategy. Basically a blend of a world Etf, local stock Etf and a bond Etf. Rebalance every quarter or so. Believe this book is available at the library. Have a good at reading it. Alternatively, have a look at robo advisories as well. These can potentially meet your targeted return with much lower fees compared to what ILPs charge. Hope this helps
