As I suspected, several large sellers have dumped all their shares at the market price (laitaan) regardless of the price.
The third-largest owner, Varma Mutual Pension Insurance Company, has disappeared from the lists entirely. Previous holding: 238,517 shares.
The fifth-largest owner has also disappeared, Danske Invest Finnish Equity Fund. Previous holding: 179,251 shares.
Säästöpankki Fonder has also halved its holding, with 112,588 shares remaining.
Twin Engine Oy and Petri Kajaani have also emptied their holdings, totaling 133,288 shares.
If this isn’t “blood running in the streets,” when major owners sell their shares at market price regardless of price or value, I don’t know what is. 
The big sellers are starting to run out of shares to sell, which is positive for the future as the selling pressure eases! 
EDIT: Trading volume so far today is ~25 thousand shares, and someone seems to have an iceberg order at a price of €1.27; I’m guessing the seller is Säästöpankki Fonder, clearing out the rest of their holdings.
