Pinned straw:
Sounds like a big step, but more details are needed to make a better assessment.
Being the early stage speculative company it is, 4DX has tended to move big on announcements like this in the past, only to steeply retreat in the months after. I have seen this movie before...
Disc.: Hold a tiny, well underwater position IRL, which I refused to exit above water on past speculative spikes like this. Woe is me!
I literally had been sitting on the sidelines for 4DX for the last month or so. Of course I miss the 40% increase!
As you say, devil will be in the details.
