Dilutors
If you have been trading penny stocks for some time, you’ve probably heard the term “dilution” thrown around quite a bit. Dilution hinders a stock from running and can push the price down as well. Dilution is most noticeable when a market maker shows a certain amount of shares at a specific price, but sells much more than the amount shown (soaking up size). For example, VFIN may be showing 10,000 shares for sale but actually selling hundreds of thousands. When I see a market maker who is infamous for dilution on a level 2 screen, it is a red flag. Frequent dilutors include but are not limited to VFIN, VNDM, PERT, and VERT. I view dilution on a level 2 screen the same way I view a resistance level on a chart; price levels that will be hard to break.
just an article I read occasionally, it says it's difficult to know exactly how many shares these diluters are holding.
