WCN Leads the Peer Pack on Price, While Shorts Quietly Rebuild

Waste Connections is the least shorted name in its closest peer cluster heading into Thursday's print, yet it carries more short interest than it has at any point in at least a year.

Among the sector's most correlated names, Waste Management and Casella Waste Systems both gained roughly 9% on the week, matching WCN's 7.3% advance. Republic Services added 5.9%. All four moved together, but WCN's short interest at 1.61% of the free float remains the softest absolute reading in the group, a function of the company's size and its traditionally low short base rather than any recent covering. The more notable point is that the 1.61% figure is the highest WCN has registered in over twelve months, reached through a steady grind from roughly 1.35% in mid-September.

That build in short positioning is happening in a borrow market that still offers no meaningful friction. Availability is extremely loose at over 4,600% of short interest, meaning shares to borrow are plentiful relative to the existing short book. Cost to borrow is negligible at 0.50%. Anyone wanting to add to the short has faced no practical barrier. The short score, at 31.2, has edged higher through October but remains well within the moderate range, consistent with a thesis-driven rather than crowded position.

Options positioning shifted more defensive on the final session before the print. The put/call ratio jumped to 0.34 on October 21, up from readings in the 0.27 to 0.30 range that had prevailed through most of October, and now sits nearly 1.8 standard deviations above its 20-day average of 0.26. That is the most protective reading in weeks, though still far from the extremes this stock has seen. The prior earnings reaction, from the July 2026 print, was muted: a 1% gain on the day followed by a fractional loss over the following five sessions.

The analyst picture has become more cautious in the weeks before this release. Morgan Stanley trimmed its target from $205 to $195 on October 13 while keeping an Overweight rating, and JP Morgan cut from $195 to $180 on October 8, also staying Overweight. Citigroup lowered its target to $175 on October 15, maintaining Neutral. The consensus remains constructive at a buy, with a mean target around $196, implying roughly 16% upside to the current price. The disagreement is less about direction than about what the print needs to show. The bull case centres on pricing power, with 6.6% price growth in Q2 partly offsetting volume weakness, and the prospect of further margin expansion in 2026. Bears point to a 2.6% volume decline in Q2 and headwinds from falling recycled commodity prices, which the company estimated would shave around $30 million from second-half revenue.

The print therefore tests whether pricing momentum can hold against softening volumes at a valuation that already prices in delivery: a PE of 27.6 and EV/EBITDA of 14.6, both easing modestly over the past month but still elevated relative to the company's own history. The level that would change the short-interest picture is not immediately obvious given the frictionless borrow market, but a miss on margins or a downward revision to full-year guidance would give the steady short build of the past five weeks a catalyst it has so far lacked.
