Technically, we shouldn't be looking at the addition of a new CEO as an event to directly increase the SP. A big name stepping into the CEO position helps bring more awareness to POET and the technology - this is always a good thing. Additionally, you can also assume that someone with a great reputation wouldn't take the CEO role unless they believed in the technology and saw significant potential ... This should add some investor confidence. All of these things will indirectly help make POET stronger but may not necessarily have huge short-term influences on the SP.
