Have you ever perused some of the stock charts of current darlings like Nvidia?   They had spikes only to fall back, and some of their believers may well have held 15+ years.  In the end, to just hold and add to that one stock would have rewarded you so much better than a 'well-diversified' portfolio.  Poet Technologies has so much potential to be one of the greats, and even in the short term - say 1-3 years - i will be most surprised if it has not moved up to a minimum of $3 and perhaps even $10.  We have already seen a doubling of the share price in really short order, and I think within a year we will be pleased with the share price.   

I have enough of the stock to sell a tiny bit if we need the money, but I plan to hold the bulk of it if I can, because I truly think it will still be rewarding holders ten years from now. 

If the stock stays down while the company keeps building its value, then it means to add more when possible.   A watched kettle never boils, so I think its better not to be so frustrated with the price today, but look to what you think it'll be a year or even three years from now.  Even Nvidia's stock chart showed so much volatility that there had to have been frustrated investors, but they are sitting pretty now.  

Management may not have done a fantastic job of pushing up the stock price, but they are doing such a great job of building a wonderful company that I don't care.  In the end, the stock price will reflect value.  It just may not do it days, weeks, or months.
