Perhaps my thought process isn't sound enough yet as I'm still learning. For me it would be Satrix Indi or an equivalent. Perhaps CML.
However, based on what GCR and AVM has said, would tend to agree. My learning's have been to stick to tracker funds/etfs for the long term but still be nimble enough to make a judgment call on the direction of the specific industries as (s)he says. I'm guessing if you're buying a FINI type fund/etf now, you're buying on the cheap with the hope of it moving up when rates start hiking again. More units purchased for the Rand now as opposed to when they're more expensive. Yet, a STX FINI hasn't seen the type of growth the INDI has. But who knows how long you'd need to be in for before prices start rising.
If I had 2mil now or a few months back I'd be all in for a INDI as the basket of companies it holds are providing services for the general populations basic needs. Surely you can't go wrong with that?
