COPT Defense Short Interest Jumps 23% in a Week

Short sellers have built their largest position in CDP in over a year, adding roughly 1.9 million shares in a single week to push short interest to just under 9% of the free float. That weekly increase of nearly 23% sits approximately 2.2 standard deviations above the company's typical weekly move, making it one of the more abrupt short-side accumulations in the stock's recent history.

The borrow market tells a straightforward story: plenty of room remains for additional shorts. Availability runs at 976%, meaning roughly nine shares are available to lend for every one already borrowed, well above the 52-week tightest reading of 433%. Cost to borrow is negligible at 0.40%, barely changed over the past week. The lending market has placed no friction in front of whoever built this position.

The options market, however, is leaning the other way. The put/call ratio has dropped to 0.60, more than one standard deviation below its 20-day average of 0.86, and sits closer to the 52-week low of 0.24 than the high of 2.25. That skew toward calls reflects more interest in upside exposure than downside protection, a contrast with the short-side activity in the underlying shares.

Analyst opinion has drifted cautiously positive over recent months, with several targets lifted after the last quarterly print. Evercore ISI trimmed its target from $43 to $41 in September while holding an Outperform rating. The consensus target of $39.75 implies roughly 16% above the current price of $34.25. The bull case rests on the company's defense-focused portfolio, where roughly 35% of leases run directly with the U.S. government, retention runs at 82.5%, and key campuses operate near full occupancy. Bears point to the structural lag between defense appropriations and actual leasing demand, typically 12 to 18 months, and a 5.9x levered balance sheet that leaves the company exposed if government tenants slow their commitments.

The stock added 2.3% on Thursday and is up about 1.2% over the past week, slightly behind the median one-week gain of 3.0% among its closest office REIT peers, which include BXP and VNO, both up roughly 5% on the week. Today's quarterly report will test whether the leasing pipeline has kept pace with the aggressive short position built in the run-up.
