WCN Short Interest Hits One-Year High After Q3 Earnings Beat

Short sellers added positions in WCN at an unusual pace following Q3 earnings. Shares short rose 27% in a single week to 5.2 million, pushing short interest to 2.04% of free float, the highest reading in over a year. That weekly move is 2.3 standard deviations above WCN's typical one-week change over the past year.

A Crowded Week at the Options Desk

The put-call ratio reached 0.82 on October 30, against a 20-day mean of 0.44. That puts the reading 1.7 standard deviations above its recent average. Puts are running at more than double the volume of calls. Before late October, the ratio had been tracking below 0.30 for most of the prior month.

Analysts Lifted Targets; Shorts Still Added

Ten firms raised their price targets in the two days after Q3 results. UBS set the highest buy-side mark at $215, up from $200. RBC Capital moved to $221. The consensus target sits at $206.48, against a current price of $184.08. Despite that analyst response, short positions grew through the same period. The stock gained 18% over the past month before pulling back 1.4% last week.

Retail Attention Spikes

ORTEX Alt Data records a retail attention reading of 3.76 standard deviations above the company's own 90-day average as of October 31, based on English Wikipedia page views and ORTEX stock page traffic. That level of engagement sits well outside normal ranges for WCN.

Separately, the Alt Data layer shows WCN spent $330.5 million on buybacks in Q2, described as the largest Q2 buyback spend on record since 2018 and up 84,874% on the same quarter a year earlier.
