That may well be his way of providing the market with a statement. And if so I would think that statement is "I am sorry that people do not understand the significance of what we have announced on the dielectric optical interposer but I do and the company’s share price is not reflecting the value of the technology.

In addition as stated earlier I am anticipating financials to be reported in March which would point to the window closing for insider buying ahead of that reporting.

Is there other news in the pipeline? Maybe. I would anticipate that they are talking to customers and potentially deals are being negotiated which would not be difficult to understand based on the success of the dielectric at this relatively early stage. POET is on record as to their desire to commercialize the technology under partnerships. If they are in talks they would still be allowed to buy up until those talks reach a point of firmness where they expect deals to close. At that point in time they would no longer be allowed to buy. 

Bottom line is any way to look at this it is a good sign for shareholders.
