I'll try to explain the mess below - this is the monthly share volume report and it doesn't like to be cut and paste into IHub
Let's just take NITE (MM) the first number 5mil 531thou is for the month of May, the 2nd number is for April and the last number of 25,678,915 is year to date. The rest doesn't really matter but if you scroll through the list you will NOT find AABA. They are new.
Your conclusion is your own - just noting a fact.
