Lakingspan. I am not familiar with the indicator you are using to monitor dilution. I wonder if you could explain it. It is not something I commonly watch or was really aware that it could be watched. I wonder if you are actually referring to distribution. Forgive me if I am in error. The only real way that dilution can occur is if people are exercising option grants to aquire actual stock. That is certainly a possibility.
I believe that this had nothing to do with dilution, solely more trading due to a combination of factors, day traders, short covering, & heavy buying on Monday Tuesday. Walrus
