Unless an LIC is a substantial holder in a bank (doubtful) then investors will only know if the LIC has bought or sold a portion twice a year via the half-year and full-year reports. Relying on NTA announcements is fraught with difficulty as all they show is percentage changes month to month in the Top 20 or 25 holdings. They do not show whether there have been purchases or not. External market activity can change that percentage without the LIC actually doing anything.
