Well, right now with a stock price of around $10, their market cap is 1.93 billion. Back last year when their stock was around $30, their market cap would have probably been around 5.75 billion. That would be a rough guess of a loss of about $4 billion, or ~60% of their value in less than 12 months.
And on the basis of this they think Linux will generate 30 billion a year within 3 years?
