I'm also just starting out Yozzi. I'm keenly watching the STXINDI. If you want more local exposure you could look at the STXRESI and STX FINI. Their charts don't look as great and as stable as the STXINDI does. But if you going to buy all 3 then you might as well just buy the STX40.
For myself I'm considering STXINDI only for definite, around 75% of the portfolio and the other 25% with off shore exposure in the DBX WORLD or DBX US.
STXINDI returned 35.59% on a lump sum investment with DIVI's reinvested. That's a decent return, and many traders I guess battle to make that in a year based on what I've read.
Also go check out
www.justonelap.co.za, there's a lot of learning material and videos on there. Perhaps it will help you.
Why not just go all into the STXIND for now while you're learning?
