Yes, BIG difference between March and now for STAU. Then there were still too many unanswered questions about overall viability, sales, the future, etc. Therefore it was treated more like any other few tick momo play. As a result of that trading action though, since then it was able to put in a double bottom at .0002 on its own steam not at .0001, which I called out here a few weeks ago.
Now there is real skin on them bones and a real buy and hold 'em has emerged. All that means is accum will continue and at some point this will be a true penny stock on its own steam.
Relative to a penny or multi-pennies given what is known at this time, all the way up through subs, STAU will still be considered cheap and will be a good actual investment for the future imvho.
