This page summarizes the ZT holdings changes quarter over quarter among those 13F filers that have reported for
the 3/31/2023 period, comparing share count change from 12/31/2022 to 3/31/2023.
Share count is compared over these two periods to provide an indication of whether ZT is being accumulated or
sold by institutions that file their holdings via 13F filings (and as always, when considering this data it is important to be mindful of the
long only reporting requirement).
