This is not a story about how Apple is doing extremely well.
It is a story about how bad the Russian economy is.
Russia's economy is being driven into the ground by two significant forces.
The first is your average bad economic forecast due to Russia's economy being tied to oil when oil is at an all time low combined with serious international sanctions that are destroying the value of the Ruble.
The more important problem is what is referred to in the article as PUTINISM and an epidemic of highly fraudulent Tunneling.
Putinism is the practice in Russia of nationalizing (ie, the government taking it by force) or ruining a business because Putin wanted to.
Recently a company called Yukos was seized after its leader fell out of favor with Putin and right after that another major company's creator has been imprisoned after also falling out of grace with Putin.
Tunneling is selling company assets at unreasonably high or low prices as a way of robbing that company. The company ownership takes a loss on the sale or purchase of the assets while the people who orchestrated it walk off with all the money. It is highly unethical and totally illegal except, apparently, in Russia.
You can see how practices like that would make a person think twice about how much their stock certificates are actually worth and why a Russian company that is supposed to have 100 billion in assets might have a much lower total stock value.
