Glad I am owning this at $40 average price. Mark my word. This drug will sale $4+ Billion rate + .6B current drug sale at end of year. with about 10-15% growth for next 4-5 year. Given high margin and low cost marketing, this itself worth $50-$60 Billion in market cap. (Buyout would occur around $60-$70 Billion. that equal to $250. My reasonable estimate is, once script known, it will trade around $180 (In 6 month, script trend should known). That is 30%+ upside with minimum downside. Buy as many as you can.
I think people compare TWTR with FB but it's totally different. You don't need to register to view all Tweet. I use TWTR but not register. TWTR is more closer to Social News Stream and you don't have to register user.
Also TWTR yet to optimize ADS and so revenue will continue raise even if User growth somewhat stall(unlikely).
I expect it go back to 50-60 range in 1 year and can be 100+ in 3 year.
