This happened before with this stock.
Over a year ago, out of the blue, the stock was bid up to over $1.50 ps. It happened quickly, with little board traffic, as if a hedge fund was simply toying with it. It eventually descended back to the pre-existing doldrums in price.
I wonder if it just didn't happen (or is still happening) again. Maybe the ceo has a rich chinese uncle who is trying to be supportive (uncle who?). Strange, really strange.
