I am not positive, but I think the .25 paper (warrants) expire in the August/September 2014 time frame. I think they had a 2 year expiry for exercise. It would be good to get clarification of this by someone on this board.
If this is the case, it does not surprise me that some are being exercised now. This is not bullish or bearish sign (IMO), most cases - it is the warrant holder managing their cash flow/timing based on their personal situation.
Never a bad thing to get them out of the way as some have suggested. Upside is, POET has more $$ in the bank.
I guess i have 6 business days, including today to make good on my "$2 in March" prediction. It's still possible.....
