Update 12-2: I have to say that given the circumstances YNDX is holding remarkably well. USDRUB is 54, Russia RTS is down 3% today!
YDNX is a great Russian company, dominating the internet search market in the Former Soviet Union. The company has stellar fundamentals and strong growth. But the stock suffered due to recent decline of the ruble . Russian currency has lost almost 50% since July.
Now, at 49 RUB per USD, the ruble is MASSIVELY oversold and undervalued, and further decline looks unlikely in the short-term. Which means that support for YNDX will probably hold. On the other hand, a modest appreciation for RUB will push YNDX over resistance line.
Either way this triangle is going to be resolved by year's end.
