I have been reading this forum for a few months now and found extremely interesting topics written by people who seem to understand finance much more than I do, people like @hedgehog @1000000CHF @Bojack @nugget only to name a few.
I started investing on IB a couple months back (living in Switzerland) and I’m up to almost 20K invested in VT. The problem I have is I can’t see with what other ETF(s) I should pair it with, as I find it quite balanced as it is, and straightforward tax-wise (for a Swiss resident).
The question is in the title: how viable would it be to build a portfolio around a single ETF?
Thanks for your input,
