<b>Our read: the CPM swing nobody prices in is the 'auction handoff' between regions</b>
As tier-1 advertisers' daily caps exhaust around their local evening, pop CPMs in that geo soft-drop for a 2-3 hour window before the next region's buyers wake up. On a global source that's a recurring discount, not noise.
— map your top geos' cap-exhaust windows from 14 days of hourly CPM logs
— schedule aggressive bids into the trough, throttle at the peak
It's boring dayparting, but on pop the margin lives in the seams.
— confidence: medium
