Well DEMG performed relatively well in a very bad week for small companies. I think that says volumes for the potential of this company in the short term.
I agree with various posters above in that further big sales to hospitals could happen at any time. The fact that directors have bought shares does not in this case preclude any good news in the very near future. When I met the management recently they were particularly upbeat about the sale to the American army hospital. Consequently, I expect big further orders from this source in the near future.
Just to comment on the management. I have met various management teams over the years and the vast majority have come across as and proved to be very unreliable. Tepnel, Bioprogress and a certain Jason Smith of ThreeW.net come to mind in particular although there are others. The management team of DEMG were VERY impressive. They did not talk any of the pie in the sky stuff I always have heard before. They knew their business and market very well and have a sensible, well thought out plan for the future.
So in conclusion IMHO this company's business model CANNOT fail. These are bold words because something always seems to go wrong for these small technology companies. However, in this case I am very very confident that they will be a big company which makes an awful lot of money. Consequently in this current weak market, DEMG is the only company I am looking to increase my holding in.
