I noticed that too. I saw the 10's on the ask and decided to check if E-Trade would allow on-line orders yet. Sadly, they are not placing trades for STAU on-line, but just after trying, the ask moved back up. I bet that was a 'teaser lot' to see whether people would get shaken. No one's getting frightened to sell though....great sign.
You gotta appreciate how stocks like this behave when they are still 'undiscovered'. Much less volatility and periodic chances of grabbing cheapies.
Go STAU!
