I honestly don't understand why Samsung Life and Samsung C&T stock prices are falling..

With Samsung Electronics, you can at least try to understand the price drop as disappointment selling (especially from retail investors) from those hoping for stock price increases through treasury stock cancellations rather than dividends, since they can't perform the same treasury stock cancellations that Hynix does.
But for Samsung Life and Samsung C&T, they can't just sell their Samsung Electronics stakes.
The driving force for their stock price increase is receiving high dividends and then redistributing those dividend profits to the shareholders of Samsung C&T and Samsung Life..
I honestly don't understand why they are falling...
It seems like the stock market is something that cannot be explained logically...
