ACO.X enters its Q1 2026 earnings release — confirmed for May 6 — with the most striking development of the past month happening on the short side: a sharp and sudden exit by bears.
Short interest dropped nearly 29% in a single week. At the start of April, roughly 1.12 million shares were on loan. By April 21, that number had fallen to 796,000 — where it has stayed flat since. SI % of free float now reads less than 0.8%, a level too low to characterise as a meaningful bearish position. What makes the move worth noting is its speed: a drop of that magnitude in less than a week signals deliberate unwinding rather than a gradual drift. Whether that reflects covering ahead of earnings, a position-size limit being hit, or simply reduced conviction against a utility trading near all-time highs is impossible to determine from the data alone. What it does confirm is that the stock is no longer a high-conviction short candidate for those who held it through March.
The borrow market corroborates that picture. Availability is extremely loose — the lending pool is essentially wide open relative to the positions outstanding. Cost to borrow has doubled over the past month, now running at 1.88%, but in absolute terms that is still cheap. It has been volatile intraday — swinging between 0.81% and 3.66% across April — but there is no sign of a squeeze in the making. The ORTEX short score of 32.7 has also fallen away, dropping from around 35 at mid-April to its current level, reflecting both the lower SI and the softening short signal.
The Street is cautious in tone rather than pessimistic. The consensus price target is C$68.86, barely above the April 28 close of C$68.42 — implying just 0.6% upside on analyst numbers. That tight gap reflects a stock that has largely been re-rated: ATCO is up over 20% year-to-date, and the mean price target has been left behind by the rally. The PE sits at 14.1x and EV/EBITDA at 8.8x, both stable over the past week. The forward earnings yield reads 7.1%. On factor scores, the dividend rank stands out — a 94th-percentile reading — consistent with the media coverage this week, which has repeatedly flagged ATCO as a top Canadian dividend pick. The 12-month forward EPS growth rank at the 85th percentile suggests the market sees a durable earnings profile ahead, though the EPS surprise rank at the 5th percentile is a reminder the company has not been known for beating quarterly estimates.
The insider picture adds a mild note of caution. The 90-day net insider flow shows roughly 59,600 shares sold in net terms, with a total value near C$2.9 million. The largest single transaction was the Chief Administration Officer selling just over 47,000 shares at C$65.59 on March 5 — a notable-sized disposal. A divisional president and a senior vice president both added smaller sales through March. None of these are blockbuster in size relative to ATCO's float, and all trade significance scores are modest (2-3 out of 10), but the directional read is uniformly one way. The dominant shareholder, Sentgraf Enterprises Ltd., holds a controlling 34.2% stake and has not moved. Among institutional names, RBC Global Asset Management added 512,700 shares as of March 31, and BlackRock added 214,000 — providing a useful offset to the insider selling in terms of institutional conviction.
With Q1 results confirmed for May 6, the prior two earnings releases produced muted same-day moves: +0.84% in February and +3.96% in the prior comparable quarter. A stock sitting near its consensus target, up 20% YTD, with insiders selling modestly and short sellers already having cut their bets, sets up a situation where the next print is less about whether ATCO can grow and more about whether management can justify the premium the market has already assigned.
