The "inflection point" is probably Denselight for now as it is that subsidiary that will drive revenue and open up the doors for POET's technology over the longer term. EBITDA positive is what the roadmap said for Denselight and this is the year (2017) for Denselight to meet that expectation. The latest price rise may actually just be related to that as the market monitors the progress of Denselight. Of course, POET can add positive momentum (fuel to the fire) as they are ready to release any news proving POET technologies advancement towards commercialization. 

Sorry to hear about the passing of your dog, lumenge (mackwheaton).
