Clean Harbors heads into its July 29 Q2 earnings report with the Street freshly bullish and short sellers barely engaged — but an options market running cooler than usual and a cluster of insider sales just one week ago.
The most immediate catalyst is analyst action. BMO Capital's Devin Dodge raised his price target on CLH to $342 from $340 on July 8, maintaining an Outperform rating — a small move numerically but notable for its timing, arriving three weeks before results. That action fits a broader pattern of upgrades that has characterised 2026 so far. Following the Q1 print in early May, a wave of firms lifted targets: TD Cowen to $335, Needham to $325, Baird to $350, and Oppenheimer to $316, all while holding positive ratings. The consensus mean target now sits at $326, roughly 9% above the current price of $297.93. Bulls point to the company's raised full-year outlook, steady hazardous waste volumes, and PFAS remediation as a longer-term growth runway. Bears focus on the Safety-Kleen Sustainability Solutions segment, where margins are under pressure and declining base oil prices are squeezing the re-refining business — a headwind that could weigh on the Q2 mix.
Short positioning offers almost no story here. Short interest is just 2.3% of free float — up about 14% over the past month in share terms, but still well within a range that signals little conviction from the bearish side. Borrowing CLH costs next to nothing at 0.43% annualised, and the lending pool is effectively unlimited: availability remains at its maximum measurable level, with over 52 million shares available to borrow relative to a short position of around 1.2 million. The ORTEX short score sits at 31.7, drifting only marginally higher over the past two weeks — a reading that places CLH firmly in the low-pressure zone. Overall, the lending market describes a stock that bears are not chasing.
Options positioning aligns with the low-conviction short picture, though it has shifted subtly. The put/call ratio has eased to 0.74, now slightly below its 20-day average of 0.79 — a modest move toward calls, not a pronounced defensive tilt. That compares to a 52-week high PCR of nearly 4.0, putting the current reading in perspective: the market was far more defensively positioned at points earlier in the year. The z-score of -0.36 flags nothing unusual. Taken together, the options and lending markets describe an investor base that is neither aggressively hedged nor particularly excited about a near-term squeeze.
What does stand out is the coordinated insider selling on July 1. Seven executives filed sales on the same day, including CEO Eric Gerstenberg, CFO Eric Dugas, Founder and Executive Chairman Alan McKim, and President Rebecca Underwood, all at $290.74. The transactions were small in dollar terms — Gerstenberg sold $164k, McKim $390k — and the trade significance scores are minimal, consistent with programmatic or tax-driven selling rather than a directional statement. Net of all activity over the past 90 days, insiders are actually slight net buyers in share terms, reflecting a small purchase by Director Karyn Polito in May. The pattern looks routine rather than alarming, but the simultaneous filings are worth flagging ahead of a print.
The valuation backdrop is not stretched but is no longer cheap. The P/E sits near 33.5x and EV/EBITDA at 13.8x, both edging higher over the past week and month as the stock has recovered from its May post-earnings drop of nearly 10%. Factor scores offer a mixed read: forward EPS growth ranks in the 82nd percentile universe-wide, and the EPS surprise rank is 71st — solid fundamental quality. The dividend score (29th percentile) reflects the company's non-dividend status; the last regular dividend payment was in 2007. Peers had a stronger week: WM rose 6.2% and WCN gained 3.5%, while CLH was essentially flat at -0.3% — a relative underperformance heading into what should be a clean setup.
What to watch on July 29 is the Safety-Kleen margin trajectory and whether management updates the full-year EBITDA range — those two items, more than the top-line number, will determine whether the Street's steady stream of target upgrades continues or stalls.
