Imho AMD itself needs to have a theory, which underpins their signing of the deal. For my clueless self, that investors have various theories and we don't know what they are is ok-ish, but that AMD has a theory but keeps it secret yet it gets the result of stock rise... is fishy.
Everyone is going in circles making suppositions and estimations based on who knows what. That can't be healty, can it? There used to be requirements that publicly listed companies act with some level of transparency, and those requirements existed for a reason. I guess. I am certainly no expert in finance.
