I find it just remarkable, that after all these years with POET we longs should know the games which are played. Interestingly it seems to me that the ongoing issues with the SP are not related to the institutional investors. After the recent CC the SP did not move significantly. These investors did not jump in or try to manipulate the share price. 

But after we learned about the CC, the SP rocketed. So it seems there were a lot of people on the sideline waiting, the first jumping possibly went already out, the last were somehow "burned". It could have been shorts, but most probably just the usual penny flippers.

All this should have no influence on us long term investors. I do not sell for a 30% gain, my plans are bigger.

But it is interesting who of the posters did not show up for long time, but are all of a sudden back on the party... And the party goes on!
