Hedge Fund Highlights
One notable move came from Balyasny Asset Management LP, founded by Dmitry Balyasny, which increased its Xylem position by more than 340% last quarter. The firm now holds roughly $105 million worth of shares, which may point to growing interest in Xylem’s long term water infrastructure exposure.
Another sharp increase came from Tudor Investment Corp, founded by Paul Tudor Jones, which boosted its Xylem stake by over 1,300%. While the position remains relatively small at around $6 million, the scale of the increase stands out and could indicate rising attention rather than a high conviction allocation.
Scopus Asset Management, led by Alexander Mitchell, also expanded its position by roughly 138%, bringing its holdings to about $12 million, adding to a broader pattern of selective hedge fund accumulation.
Renaissance Technologies, founded by Jim Simons, increased its Xylem stake by more than 70% to approximately $48 million. Given the firm’s systematic approach, the increase may reflect improving model signals rather than a discretionary view, and for investors this activity points to incremental support from quantitative managers.
