Are we looking at the same stock? I am confused where this data is coming from. What I see is stock slightly higher than it was week ago, fell compared to day ago, and the change is 1-2%, way less than you 50% fall claim.
"$120 price target" is a prediction about the price in some near-ish term time range.
As I understood the message, the GP post stated their predicted price for Adobe, and the target price for the options they purchased, not any change in price that has already occurred.
