Shorts have no idea as to which type of stock DDD is ?
This is very unusual stock. This is disruptive technology. In last 3 years, pps went 20 times. In next 3 years pps can again go 20 times from present value. Very soon, most of manufacturing (which is 50 Trillion world market) will be done by 3D. Any items made in Millions (i.e. Car, etc) can still be made by traditional manufacturing. However, any Custom item/order or any items manufactures in hundreds or even thousands will be made by 3D.
