SW Shorts Retreat as Stock Drops Into Thursday's Results

Smurfit Westrock, the Dublin-domiciled containerboard giant formed from the 2024 merger of Smurfit Kappa and WestRock, reports Q3 results on Thursday with its shares down 13% over the past month to $40.33, a sharper retreat than most of its packaging peers.

The short position has moved in the opposite direction to the share price, and that contrast is the most distinctive feature of the current setup. Short interest fell 16% over the past week to 4.3% of free float, a decline that ORTEX calculates at 3.1 standard deviations below the company's typical weekly movement over the past year. Shares short peaked above 26 million in mid-October before dropping back to 22.5 million. That unwinding happened as the stock was sliding, which is unusual: short sellers reduced exposure into weakness rather than pressing the bet. The borrow market gives them no reason to rush: availability is ample at 575%, meaning roughly five shares remain available to borrow for every one already lent out, and the cost to borrow is 0.46%, well within its normal range. Nothing in the lending market points to stress.

Options positioning leans the other way. The put/call ratio of 0.27 sits slightly below its 20-day average of 0.28, meaning call activity continues to outpace puts. That relative call skew has persisted through a month of share-price declines and sits near its most call-heavy reading of the past year. The combination of short covering and call-heavy options flow suggests some investors see a floor near current levels, even as the stock has underperformed. Closest peer International Paper rose 3.3% on Wednesday, while Packaging Corp gained nearly 4% on the week. SW fell 2.7% over the same period, against a peer median of roughly plus 1.1%.

The analyst community is broadly constructive but has been trimming targets. RBC Capital cut its target to $55 from $60 earlier this month, and Truist Securities and Citigroup each moved to $54 from $57 in October, all while keeping buy-equivalent ratings. At $40.33, the stock trades at a meaningful discount to even the revised targets, and the forward PE of around 12x is close to multi-year lows. The bull case rests on containerboard pricing recovery, Latin American volume growth, and the synergy runway from the merger. The bear case points to an 8.7% year-on-year drop in corrugated volumes, weakening consumer packaging shipments, and a guided EBITDA range of $4.9 to $5.1 billion for FY25 that was already cut by $100 million from prior guidance. Margin pressure in EMEA and APAC adds further weight to that argument.

Retail attention has risen sharply ahead of the print. Wikipedia page views for Smurfit Westrock are running at a z-score of 2.8 against the company's own trailing 90-day history, the highest level of retail interest in the stock in recent months. Thursday's results will test whether the company can show any stabilisation in corrugated volumes at a price that already implies a great deal of bad news has been absorbed.
