GKOS Holdings Changes image
This page summarizes the GKOS holdings changes quarter over quarter among those 13F filers that have reported for the 12/31/2019 period, comparing share count change from 9/30/2019 to 12/31/2019. Share count is compared over these two periods to provide an indication of whether GKOS 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).
