MFA shorts rebuild as earnings loom

MFA Financial heads into Thursday's earnings print with short sellers adding positions at the fastest clip in months, while options traders have shifted notably more bullish, creating an unusual tension in the setup.

The short side is the clearest signal this week. Short interest has climbed to 6.5% of the free float, up 9.2% over the past week and 18% higher than a month ago. That is the most sustained rebuild since early October, when shorts briefly ran above this level before retreating. The ORTEX short score has moved in lockstep, rising from 48.1 on October 22 to 54.0 now, its highest reading in the recent window. Despite the short rebuild, the borrow market remains relaxed. Availability is at 246%, meaning lenders have more than twice as many shares available as are currently borrowed, well above the 52-week trough of 200% hit in early October. Cost to borrow is just 0.51%, down 42% over the past month. Shorts are adding conviction, but they are doing so cheaply and with no squeeze risk in the near term.

Options tell a strikingly different story. The put/call ratio has dropped to 0.67, below its 20-day average of 0.72, and is running near its lowest reading of the past year (the 52-week low is 0.57). That is a call-heavy posture, suggesting options traders are positioned for a pop rather than a drop into the print. The divergence between rising short interest and a bullish options skew is the most interesting tension on this stock right now.

The Street is cautious on valuation but not outright bearish. The most recent analyst action came on October 15, when Citizens trimmed its price target to $8 from $11 while keeping a Market Outperform rating. BTIG also cut its target earlier in October, to $9.50 from $10.50, again holding Buy. The mean analyst target of $13.25 implies substantial theoretical upside from the current price of $6.64, though that gap reflects the speed of the stock's decline rather than fresh Street optimism. MFA has fallen 13% in the past month. The fundamental picture explains why: the bear case centres on distributable EPS of $0.12 in Q2 badly missing consensus, while the $0.36 quarterly dividend remains uncovered. Management cut its 2026 distributable EPS guidance to $1.12 from $1.36, and book value per share slipped to $12.70. The price-to-book multiple has compressed to 0.55x. The bull case rests on credit-loss normalization into 2027, with ex-loss distributable earnings running closer to $0.35 per quarter, and the Lima One lending franchise posting $316 million in Q2 originations with improving delinquency trends on recent vintages.

Factor scores add nuance. MFA ranks in the 87th percentile on EPS surprise, meaning the company has historically beaten estimates more reliably than most of the market. The dividend score sits at the 95th percentile, an artifact of the yield rather than coverage comfort. The short-score rank is in the 17th percentile, flagging that positioning looks more aggressive than most peers. Among correlated names, the sector has broadly sold off: CIM fell 1.2% on the week, EFC dropped 3.1%, and AGNC shed 3.8%, so MFA's 1.3% weekly decline actually represents a degree of relative resilience within the group.

One mechanical footnote to the near-term calendar: ORTEX puts an 80% probability on MFA seeing a share-count reduction in the CRSP US Small index at the December 2026 Quarterly Review, with an estimated $10 million of index-tracker selling on the trade date of December 22. The rank date is December 4 and announcement is expected December 7. That is a known, modest selling overhang roughly seven weeks out.

The critical variable for the week is Thursday's earnings report. With short interest rising into the print, options leaning bullish, and two consecutive quarters of earnings disappointment fresh in investors' minds, the reaction to Q3 distributable EPS and any update to the dividend coverage trajectory will determine whether the short rebuild was well-timed or the options crowd had the read right.
