Unraveling the Open: Premarket Structure and Imbalances on NYSE and AMEX
·
Feb 5
For each listed security, there is a single official opening price published by the primary listing venue. That price is the same for every market participant, regardless of where orders were placed overnight, which venue was used, or how fragmented premarket trading appeared. It does not emerge organically from early prints and it is not negotiated after the fact. It is established deliberately, through an auction designed to reconcile supply and demand into a unified starting point.
I'll continue adding new examples as they occur.
