PORT Holdings Changes image
This page summarizes the PORT holdings changes quarter over quarter among those 13F filers that have reported for the 12/31/2023 period, comparing share count change from 9/30/2023 to 12/31/2023. Share count is compared over these two periods to provide an indication of whether PORT 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).
