Ann: Ceasing to be a substantial holder from PTM, page-37

After browsing that document I found

You will see IMU in the top 10 with 2.4% of their portfolio.
I searched through the last year of the historical reports and don't see IMU in the 10, with the exception of Feb 2018 & Nov 2017. With seeling coinciding around that time.
I could be wrong but it appears to me that when IMU hits the top 10 or around 2.3% or 2.4% of this portfolio they sell. DYOR but I for one will be looking at the future monthly reports.
