Comprehensive Analysis of Ursa Fund Management, LLC (SEC 13F) – Q3 2025

1. Portfolio Overview

Ursa Fund Management, LLC has executed a dramatic transformation of its investment portfolio during the third quarter of 2025.

2. Key Holdings

The portfolio is dominated by three major financial services positions, which together form the core of the fund's strategy:

  • Apartment Investment & Management Co (AIV): This is the flagship holding, representing a massive 53.84% of the portfolio ($40.44M). This position indicates a strong bullish stance on the residential real estate sector, specifically apartment REITs. The size of this stake suggests the fund views AIV as significantly undervalued or poised for a turnaround/acquisition.
  • Mr. Cooper Group Inc (07WA): Comprising 26.01% of the portfolio ($19.54M), this position reinforces the fund's focus on housing and mortgage finance. As a major mortgage servicer and originator, Mr. Cooper benefits from housing market activity.
  • Rocket Cos Inc (RKT): Accounting for 12.68% ($9.53M), Rocket completes the "housing trifecta." Combined with AIV and Mr. Cooper, nearly 93% of the fund is exposed to the US housing ecosystem, ranging from property ownership (AIV) to mortgage servicing and origination (07WA, RKT).
