I speculate that someone had a market order to sell VTI at the end of the day this past Friday 11/23 that was executed after hours with someone's bid for $71.60
This was just interesting, for me, to see that the days trading volume of nearly 800k shares pushed the price up 1.3% and that was almost wiped out by the sale of a single lot of 100 shares
Buyer, and seller, beware
