Who owns WGS?

212 tracked 13F filers

212 tracked 13F filers disclose a position in WGS as of the latest SEC 13F filings, a combined $1.8B in reported value. Holders and values reflect the 13F filers Arkolith currently tracks, not the entire institutional universe. Counts and totals are a floor, not the full institutional ownership.

All quarters use one ordinary-share-equivalent series. Historical ADS are converted at 2 ADS = 1 ordinary share. Expand a row for the exact calculation; the residual is not classified as a trade.
3 source-reported value rows are withheld because the reported units do not agree with same-security peers. Share counts remain visible and unchanged.
