Can you please expand on what is your concern?
Maybe that’s for a different discussion, I am skeptical of them allowing rebalancing however many times one likes with no cost, there has to be a cost somewhere…
I know we use the term “index funds” to refer to mutual funds here, but my understanding is that mutual funds do their trading daily, after market closure (among the reasons Bogle preferred them to ETFs). My point is tangential, as we’re talking about when VIAC/Finpension are doing THEIR trading, which is once weekly. I still wonder if they could lock in the price for any sell/buy order for the day it was submitted, as buying 1 week later could work out badly too (though by a smaller % than selling as stocks ride the elevator down and take the stairs up!).
