No short in his right mind would touch Axion because the potential downside on the stock price is capped at $0.50 but the upside potential on the stock is unlimited. It would be a real suckers bet for a short at this price.
What most investors don't take the time to study is volume trends over time. In calendar 2009, total trading volume was 7.2 million shares. In calendar 2010 the total volume was 22 million shares. The YTD total for calendar 2011 is 50.8 million shares. There's not enough market volatility to attract day trader types, so it looks like the bulk of the buying has been coming from investors who have a "stick it in a drawer for a couple years" strategy. If that's the case, and it's admittedly a big IF, then the pool of willing sellers is looking a lot like a puddle. Once it dries up completely the stock price will have to move to a level where the buyers over the last 18 months become willing sellers. Dry powder is always a good thing to have, but waiting until the puddle is completely dry carries its own risks that the price will run away from you.
