RE:SUDDEN STRONG BUYING IN NANOYes, it's definitely there. Some times these "chunky" moments are just some single eager buyer. I'm now seeing it also come in from House 1 (anonymous), again taking shares at the ask right up to $3.75 now.
As retail, we are at the bottom of the food chain of knowing what might be going on. But through the trades, you can definitely see the footprints of those higher up the food-chain. It's these sudden changes in the stock's "personality"..the way it trades, that often signify something..in this case something positive, is now out there.
I'll look for further confirmation here in the buying, but I'm definitely liking what I'm suddenly seeing.
