Possibly, but the key variable is "How many shares did HDSN accumulate in the sub penny level?" We will never know.
Also, HDSN normally induces selling. He bidwhacks, thus causing sellers to jump in front, bid whacking him, and lowering the ask. Then once enough sellers have joined him, he pulls back and lets others sell. He preserves his shares for further drop downs. I've noticed this time and time again. He sells only enough to stop upward momentum, then drops back as others sell.
