I'm a fresh grad, new to investing here. Does it make sense for me to invest in both STI ETF and Robo-Advisors to diversify? What should the split be in terms of how much to invest?

Hello!

The purpose of diversifying is to eliminate as much as risk possible so that only market risk (risk that cannot be diversified away) remains.

With a budget of around $400, I would put it all in a robo advisor. Reason being is because i cannot ascertain how much risk i'm minimsing by getting both portfolios. On the other hand, if I use a robo adviser (Stashaway for example, which I use) I can be certain of the risk that I'm taking up through their portfolio's risk index. Do let me know if you need a referral code. Hope this helps!

I would recommend not investing in the STI as the growth is too stagnant! If you only have $350-$400 every month to invest, just put it into a robo advisor and they will help you to diversify your portfolio!

Warren Buffett recommends retail investors to just invest 90% in S&P 500 and 10% in Short-Term US Govt Bonds. If your investment horizon is long (20+ years) don’t waste time (and money) investing in the STI
