Why It Moved

A stock does not move because news is simply good or bad. It moves when new information changes the assumptions already reflected in the price.
THE READING ORDER

Expectation → new fact → estimate change → repricing

Each case separates verified company facts from interpretation. It explains a historical mechanism; it is not a recommendation about the security today.
