there is hardly any short interest- and most brokerages don't allow short under $5-- scottstrade, for instance, which is the one I use doesn't allow it.
Also, the volume is miniscle, so any shorting done in a day-- say 50K shares, would only be $200K AND even that volume of shorting would strongly move the stock to the negative.
Again, this is not a shorting stock for the volume and price is too small.
What this stock is is a cash cow for the main stockholders and us outsiders are here simply to buy the hype and it'll prove to be worthless.
Look up the patents that they hold--- go to the US Patent Office and type it in. Especially look up the patents filed in the past by the chief scientist.
Also, look up the CEO's past. And what he did with his previous company. This is the SAME.
You can make money with the stock, but only if you buy low-- like it's coming to $3.5 again likely shortly and within a month or two to $5 and back again.
