pippin15: A good idea would be to see if the descrease in price of CDPR's shares has something to do with Cyberpunk itself or not. Sometimes these decreases are completely normal.
Phasmid: Yep. Releases and good news tend to be priced in to share prices already, and are often used for profit taking. The example I gave in another thread was AMD, pretty much non stop good news in all their financial statements but their share price drops after each one because the good news is already priced in.
Of course the prices fluctuate around news, but I don't think it's that common for an established company to lose 40% of the value with good news..
It's interesting to note that the share value started crashing on fourth of December, which is a few days before the reviews came out. Also on fourth of December, a certain Kicinski dumped nearly half a million shares.
