In a notable portfolio move, Dennis Hong's ShawSpring Partners has liquidated its entire stake in CoStar Group (CSGP), selling off 339,080 shares. The sale had a reported value of approximately $13.68 million and previously accounted for 5.11% of the firm's reported 13F portfolio. CoStar Group is a major provider of information, analytics, and online marketplaces for the commercial and residential real estate sectors.
This trade was disclosed in a quarterly 13F filing with the SEC, which reflects positions held as of June 30, 2026. Due to the delayed nature of these reports, the transactions occurred at an unknown time during the second quarter. Earlier in 2026, CoStar faced public criticism and pressure for board changes from other activist investors, like D.E. Shaw, regarding its spending on the Homes.com business and overall stock underperformance.
