Sigma is in the 3D printing space as a quality control for printed objects. Sigma does not make 3D printers, so if GE is talking with 3D printing companies then it really does not mean anything. However if they are in talks with another 3D company that does what sigma does that is a different story.
I would like to see some news about yesterday. What the stock does on a short term basis has is not important. Whether the stock goes from 4 cents to 12 cents in not that important. In the grand scheme of things this is not important.
