Rocket Cos (RKT) is a crowded U.S. equity short, with rising borrow costs and squeeze risk tied to rate and M&A catalysts.

Rocket Companies (formerly Quicken Loans), an on-line mortgage lender, is currently one of the most heavily crowded single-name US equity shorts.

Short Interest % Float has climbed from 13% in January to over 40% today, as fundamental shorts crowd into the bearish bet of “higher for longer interest rates” narrative, a headwind for the US housing market. Event-driven funds have joined the crowd as RKT is the acquirer of two pending acquisitions (RDFN & COOP) due to close this year.

SI Utilization hovering near 98%, and financing fees rising above 15%, both signaling limited stock loan availability and elevated demand, which is typical of crowded shorts.

With S3 Squeeze and Crowded Scores at 100 and 92.5 respectively, RKT should be closely monitored for potential short squeeze rallies on the back of any positive news catalyst.
