DCA monthly into Syfe Equity100 and VOO on FSM?

Previously DCA-ed monthly into Stashaway 22% and Nikko STI since last July. Stashaway quite cui (XIRR = 5.21%), STI surprisingly better than what people are saying (XIRR = 17.88% inclusive of dividends) because I think I started when the price was low-ish. Anyway stopping the DCA from this month to explore better options...

​

Put in 1.5k and planning to DCA monthly into Equity100. Also planning to DCA into VOO on FSM with RSP. Should be better than the Stashaway + STI combo right? Does it make sense or am I overdiversifying?

​

Also just put in 1.5k into Syfe Select (QQQ, TAN, ICLN, ARKG, SMH, CHIQ, ESPO, VBK). Not much research done here to be very honest but just industries that I do believe will grow in the future.

​

(Using robo because easy to DCA and fractional shares and I don't need to think about conversion and can buy everything at one go. Will use other platforms if I want to buy during dips?)

​

Ok or not for low effort passive investing? Don't really have the time or brain power to do in-depth research for stock picking as of now...... If anyone has suggestions on where/how to invest my incoming bonus (~6k) that'd be great too :-)
