Mauser96 you're absolutely wright.
investors in AMAVF are mostly private investors, and the longs/shorts are mostly in the hands of professional investors, and there is a lot of manipulation.
The professional investors are in ARCM.
In Europe there is more understanding about what Arcam does, what the position is in the market, partnerships, support from the European Commission, etc.
And don't forget, the majority of the international financial power will not be happy when a small European company in the 3DP sector is going sky-high when companies like DDD and SSYS are losing interest from the international investors because they have a long way to go in making any money.
By the way, I believe EOS, SLM Solutions Group, and Concept laser will be the winners in metal printing, SSYS in plastics offcourse...
Time, time will tell.
In time all manipulation will pay for the truth.
