Only if you want to continue to miss the stock market rally like you have the past four years. This is a source of funds, nothing more. This company has been unable to make a profit on a consistent basis.
at current prices, w/China turning down precipitously at the margin, of course you would not touch it, but at $1.75 it might be worth a nibble. At that price it would not be quite at cash value per share, but it would be almost one dollar below net working capital per share w/no outstanding debt. At that level the risk would probably be only "dead money" as the company knows how to keep a clean Balance Sheet.
