Ya, no one knows when the shoe will drop and POET announces the sales, or even if they will be able to sell their product, although that seems highly likely at this point.
Shorting a stock is fraught with peril, especially a stock like this that is pre-revenue (outside of Denselight's contributions) and expected (hoped?) to announce some relatively soon.
Big kahunas on anyone that chooses to short POET, especially since the downside, at these prices, is minimal.
I too would be surprised if the shorts increased substantially on the next report.
