Shares that are added to the OS (diluted) don't have to be added into the market (i.e. traded) in the same time frame. You could see an increase in the OS and then wait a while to see the shares traded on the market.
I watched one company a few years back that has an increase in the OS of 10 million over the span of a week. In that same week, the total volume of shares traded was only 1 million.
In the case of ABCE, the total volume allows the shares to have hit the market. Doesn't mean that is what happened.
Either 80 % of the trades were the company selling shares, or some/all of the diluted shares are yet to hit the market. IMO
