Ellington Financial enters the week with an unusual combination: short interest has climbed meaningfully over the past month, yet shorts have been covering all week and the options market is the least bearish it has been in months.
The positioning picture here is more nuanced than the headline number suggests. Short interest has risen 17% over the past month to nearly 6% of the free float — a level that earns genuine attention in a mortgage REIT. But the week-on-week direction is the opposite: shorts trimmed about 6% of their position between Monday and Tuesday, pulling shares short back toward 6.38 million from a recent peak near 7.5 million at the end of July. The borrow market adds further context — cost to borrow is just 0.45%, barely above where it has been all summer, and availability is running at 428%, meaning there are roughly four shares available for every one currently borrowed. That is a loose lending market, not a stressed one. The 52-week tightest availability reading was 286%, so even at the month's most squeezed point the market was never close to stressed. Overall, the short setup looks like tactical positioning rather than a conviction bear thesis — and that conviction appears to be fading this week.
Options positioning reinforces the cautious-turning-constructive read. The put/call ratio has drifted down to 0.71, more than two standard deviations below its 20-day average of 0.74. That is the least defensive options positioning EFC has seen in months, a notable shift given the 52-week range runs as wide as 5.35 on the high end and 0.22 on the low. Calls are now meaningfully outweighing puts — unusual for a name where the put/call has run closer to 0.77 through most of July. The signal is consistent with a market that has recently grown more comfortable with the stock.
On the Street, the analyst picture is quietly improving. UBS raised its target to $14.50 from $14.00 this morning while keeping a Neutral rating — a modest but timely nudge above the stock's $13.61 close. The consensus mean target is $14.86, implying roughly 9% upside from here. BTIG downgraded EFC to Neutral back in June, but the broader analyst pool — Piper Sandler, B. Riley, KBW, and JMP among them — retains a constructive tilt with targets generally in the $14–$16 range. The valuation picture supports that read: EFC trades at just under book value (price-to-book of 0.98) and at a P/E of 6.9, with the earnings yield running at 14.5%. Factor scores flag dividend strength as an outlier — ranking in the 99th percentile — while the short score itself has been easing all week, dropping from 52.6 on August 7 to 49.4 today, a move that tracks the retreat in short interest.
Institutional ownership adds one thread worth watching. BlackRock added 1.18 million shares in its most recent report to bring its stake to 16.2% of shares outstanding, the dominant position in the register. JPMorgan Asset Management added 521,000 shares in July. The founder-linked Ellington Management Group and CIO Michael Vranos — who appears separately as a personal holder — together retain meaningful skin in the game, though Vranos has been a consistent seller at prices in the $12–$13 range over 2024, and the stock has since edged above those levels. Most recently the insider log is quiet; the last open-market purchase was Chairman Ronald Simon picking up 5,500 shares at $13.56 last September.
The next earnings date is November 6. The two most recent post-earnings reactions were both positive: the stock gained 2.5% the day after the August 7 print and added another 4% over the following five days. With shorts backing off and options traders leaning more bullish than at any point in recent months, the tone heading into the next print — and what the macro backdrop for mortgage spreads looks like by then — is what bears watching most closely.
