I'm thinking that volume came out of nowhere unless I am missing something. There comes a time when someone needs to sell their stake even when they don't want to. Could be that the sale was orchestrated with a willing buyer to support the stock. Pure conjecture on my part but a little buying fuel for this one could have help create the liquidity. Traders are like dogs who chase cars sometimes. They have little interest until it starts moving then get excited.
