ACCO Brands heads into its Q1 2026 results today with short sellers at their most aggressive in over a month — and options traders flipping sharply bullish, a split that makes the print worth watching closely.
The short interest story is the clearest signal this week. Shorts have rebuilt meaningfully over the past month, with short interest climbing nearly 30% in 30 days to reach 8.8% of the free float — a level not seen since early April's brief spike. The move has been steady rather than panicked: positions grew around 2.3% week-on-week, suggesting systematic accumulation rather than a single catalyst-driven push. Days to cover run at 5.9 under official FINRA data, giving the position real weight on any positive surprise. Borrowing costs, however, have moved in the opposite direction — dropping 43% over the past week to just 0.49% APR. That is close to the cheapest borrow has been all year. Availability, while not disclosed at extreme levels, remains well-supplied for new positions. The picture is one of bears adding quietly at low cost, with no squeeze pressure building.
Options positioning sharply contradicts the bearish short interest trend. The put/call ratio has collapsed to 0.019, near the 52-week floor of 0.014 and roughly 1.2 standard deviations below its 20-day average of 0.46. That is an almost purely call-dominated book — a striking contrast given that just two weeks ago the PCR was running above 0.78. The shift appears to reflect traders positioning for an upside surprise on today's Q1 print rather than hedging for downside. Whether that optimism is warranted is precisely what the earnings release will answer.
The Street has been cautiously constructive but with a dwindling conviction. The sole active coverage comes from Barrington Research, which trimmed its target to $5.00 in March from $6.00, while maintaining its Outperform rating. At the current price of $3.24, that target still implies roughly 54% upside — though the gap reflects the stock's persistent decline more than sudden analyst enthusiasm. The EV/EBITDA multiple of ~6x and a P/E of 3.7x are undemandingly cheap on paper. The EPS momentum factor scores are weak — ranking in the 8th and 19th percentiles on 90-day and 30-day windows respectively — pointing to a deteriorating estimates backdrop ahead of today. EPS surprise history ranks in the 41st percentile, roughly in line with the universe. That is not a setup that historically triggers multiple expansion even on a beat.
The institutional register offers a stabilising footnote. The Capital Management Corporation added over 1.4 million shares in Q1, the largest incremental move among the top 15 holders. Allspring and BlackRock also added modestly. Net insider activity over the past 90 days is nominally positive — approximately 199,000 net shares — though the March cluster consisted largely of equity awards followed by small tax-withholding sales from the CFO, CEO and several SVPs at $3.32. None of those trades are large enough in dollar terms to read as a directional signal on fundamentals.
History provides a sober reminder of what post-earnings moves can look like here. The most recent print — March 2026 Q4 results — sent the stock down 7.2% the following session and 17.1% over the subsequent five days. The prior comparable saw a 1.5% single-day decline with a five-day move of negative 5.1%. Both readings suggest the stock has struggled to hold ground after reporting, regardless of whether headline numbers beat or missed. Close peers had a rough week too: QUAD fell 10% on the day and nearly 8% over the week, while BCO and HNI each declined 1-4%, suggesting the broader sector remains under pressure.
The key watch tonight is whether ACCO's Q1 revenue trajectory — and any commentary on tariff exposure in its global supply chain — shifts the gap between a call-heavy options book and a steadily growing short position. That divergence is the tension the print will resolve.
