Should I invest through investment linked policies or robo-advisory? Are there other good options to earn passive income? What will be a good mix of portfolio? I have only worked for 2 years or so.

Forget about ILP. You can get better returns going to lower cost robo advisors.

For me, I have both.

Imo, you should always do robos or DIY first. This is due to the low fees.

I only went into an ILP, Aia Pro Achiver, as I have done the above and have spare cash lying arnd. So I support support my agent abit by putting small amount. Some might argue that ILPs are a waste of money due to high fees, but I see this as a way to spread my eggs over different mediums. I've gotten decent returns. 11% so far this year, net of fees, less than half a year. AIAPA is pure equity/investments, no insurance portion, swhy the better returns and will have lower fees.

Looking that you've only started working, your best bet is to go for growth instead of passive income. Passive income from equities would usually come from high dividend stocks that give you a range of 3-7%pa. But you see, with a low capital, 3-7%pa, you'll get peanuts.

Hence I would suggest you grow your wealth and once u have a substantial capital,, transition to dividend stocks such as reits or even use SYFE Reit.

Lemme share with you my plan. Say you are 25yo, you invest 3k lump sum and 300/month for 40yrs using ETFs/robos. At 8%pa growth, that will be arnd 900k at 65 due to compound interest. So assuming you have 900k and it appreciates at 8%pa, that's 72k. From this 72k you can take out 3k/month and you'll still have spares. So essentially, your 900k doesn't drop or it may drop slowly. Hence, passive income.

Start investing early for the compound interest effect.

Just my 2cents worth. You do you.
