In early Oct, ST had posted some comments following the CC. I asked the same question about Platinum investors.

I got a PM response from someone on the board as follows - "Platinum means investors who will buy in and be prepared to sit on the stock for 3-5 years etc, awaiting full maturity of the potential of POET (no short term investors ... exactly what we want)."

Sounds like many of us!! :)

Hope this helps.
