Yes, we know that, the company has rarely been otherwise, and POET is not unusual in that respect, being a pre-production company.
I too have bought shares at higher prices recently, but I doubt the price decline is directly related to their cash postion, although there could be a little concern out there.
In any case, apologies if you are in fact not shorting the stock, there is a lot of selling going on, and so close to orders it seems a bit premature...at least...especiallly if you've been around as long as some of us...
