I've followed and invested in HAT since Jan 07 - looking at what's happened, I decided I would have to trade this stock, so sold a good chunk on the recent news. At the moment, the downside risk seems higher than the possibility of a move higher, so I have reduced my investment and will buy back if the price falls. Don't like this cycnical investing, but I have to protect myself, however good the discovery.
Hope it does go higher soon, though.
