Vanguard, on their page which lists the 30 day average bid/ask spread for their various ETFs, currently has 0.02% and $0.02 as the spread for VTI:
However, if I lookup VTI on Morningstar, it has a bid/ask spread of $2.31, or 2.19%.:
Is it really true that the current bid/ask spread is over 115 times the 30-day average? Why is Morningstar's quote for the current bid/ask spread number so much larger than the 30-day average listed by Vanguard?
