Go ahead and try to short a penny stock any penny stock and especially a subpenny stock, it is basically impossible unless you are a MM. More so who would want to short a subpenny stock, because the risk to reward ratio is ridiculous. Yes you could make .0075 per share if the stock went to zero, but the loss potential is the sky is the limit!
The important thing is not to stop questioning. Question everything (Albert Einstein), because Fools rush in where wise men never go!
