I know this my be hard, and I often don't practice what I preach (as is often the case with my residents and students lol) but I think the best course of action right now is not to react to the SP on a daily basis (or better yet not check it- at least not as much).
Nothing has changed with the technology and potential, in fact in the past year some major players have joined the company and POET took a different path - IMO a better path. One can only expect this major direction change would initially result in a selloff as shareholders expecting results from the original pathway cut ties from frustration. Unfortunate for them as I believe the current path will yield greater results.
Go and enjoy the holidays! As well as a potential huge return in 2016 on POET as I truly believe we have a major player involved helping us bring this to the market and secrecy is a must - our retail shares are peanuts compared to what may come.
