I have very similiar thought.
Rember the spike about a month ago or so in insider buying? There is even an article about in regards to that http://translate.google.com/translate?depth=1&hl=en&ie=UTF8&prev=_t&rurl=translate.google.ca&sl=de&tl=en&u=http://www.pinnacledigest.com/blog/pinnacle-digest/poet-technologies-tsx-venture-tech-stock-you-havent-heard
The price around that time was in $0.50 and short after that run up.
So yes, me thinks so, some of this PP was for the POET team in a lab, because they deserved it.
