The number of shares sold at higher volume last fe

The number of shares sold at higher volume last few weeks adds up to something around $100k to $300k depending on what chunks you count. Was not dilution. This is approximately what 3 firms selling off 15M shares each adds up to. We're either at the end of that, or some silent shark has exited for sweeter waters. Given when it started, I think it was the firm's because decision was instant and mechanical. But still a mystery.
