Russians trade on it. Maybe they do have an overly rosy view of the company's fortunes, I dunno -- I don't know much about their business, how sensitive it is to the conflict and sanctions.
The stock price movement is easier to reason about, I guess. By that metric they've had a worse year than Salesforce, Netflix, Uber, Google. I'd agree that the conflict isn't good for them, but "worthless" is a bit strong for my palate.
Beaten down, but not "nearly worthless", and it is traded. (Not on the NASDAQ though.)
