Casella Waste Rallies 12% as Options Sentiment Flips Bullish

CWST enters July with its sharpest one-week gain in recent memory — up 12.5% to $96.97 — while options traders have abruptly pivoted from defensive to bullish positioning, creating the week's most interesting tension heading into a late-July earnings report.

The options shift is striking. The put/call ratio has collapsed to 0.92, now running well below its 20-day average of 1.25 — more than 1.3 standard deviations beneath normal. For context, the ratio sat above 1.55 as recently as early June. That's a rapid rotation away from downside hedging toward call exposure, coinciding almost exactly with the stock's re-rating higher. Borrow conditions reinforce the benign tone: availability is running at a healthy 217%, meaning there is roughly twice as much stock available to borrow as there is currently borrowed — well within normal range and near the top of its 52-week band. Cost to borrow ticked up about 8% on the week to 0.58%, but that level is historically low. The lending market offers no squeeze pressure.

Short interest is elevated but not extreme. At 7.4% of free float — around 4.6 million shares — it is a meaningful position, and it rose roughly 10% over the past month before easing back slightly this week. With days-to-cover at 7.6 per the latest FINRA fortnightly read, a sustained rally could create some covering pressure, but the loose availability profile suggests no panic in the borrow market yet. Short positioning looks more like a structural hedge than a conviction bear bet.

The Street is broadly positive, though not without reservations. The consensus leans bullish, with UBS maintaining a Buy and a $122 target — trimmed last week from $130. Barclays upgraded to Overweight in early May. JPMorgan sits at Neutral with a $110 target. The mean price target across the group is $111.20, implying modest upside from current levels at $96.97. The bull case rests on CWST's diversified Northeast franchise across collection, recycling, organics, and landfill — a model that generates resilient cash flows in a largely non-discretionary industry. Bears point to economic sensitivity in New England, fuel and commodity price exposure, and a valuation profile that leaves little room for error: the trailing P/E is above 65x and EV/EBITDA sits near 13x. The 30-day forward EPS momentum factor ranks in the 92nd percentile — an encouraging recent trend — but the 90-day reading has fallen to just the 15th percentile, suggesting the improvement is still early-stage. The ORTEX short score sits at 60.5, near the upper end of its recent range but not at a level that signals acute short-side pressure.

Institutional ownership is stable and skewed toward passive holders. BlackRock holds 14.2% of shares, with a near-flat recent change. Capital Research and Vanguard each hold around 4-7%. Wellington trimmed by roughly 95,000 shares in Q1, while Goldman added about 137,000 — a modest divergence within an otherwise quiet ownership picture. The founder family — John and Douglas Casella — together hold around 1.75% of shares outstanding, with no recent changes. Insider activity has been one-directional: President Ned Coletta sold approximately $1.1 million in shares across three transactions in late May, and a cluster of executives including the CEO, CFO, COO, and General Counsel all sold small positions in mid-March. Net insider value sold over the past 90 days is approximately $3.1 million — modest relative to market cap but consistently in one direction.

Recent earnings history adds a layer of interest. The last three prints produced next-day gains of 2.2%, 9.0%, and 11.2%, with five-day moves of 6.8%, 7.8%, and 9.4% respectively — a notably consistent pattern of positive post-earnings momentum. The next scheduled release is July 30. With the stock already up 18% over the past month and options traders now leaning toward calls rather than puts, the dynamic heading into that print — whether the rally compresses the post-earnings upside or sets the stage for another leg — is the central question worth tracking over the coming weeks.
