Olin Corporation heads into its May 8 earnings call with short sellers broadly retreating — yet the stock keeps falling anyway.
The short interest story has moved fast. At 9.2% of free float, OLN remains meaningfully shorted, but that figure has dropped by nearly a third over the past month, from roughly 14.9 million shares short in late March to just over 10.5 million today. Borrow conditions remain loose: cost to borrow is a negligible 0.42%, and availability is ample, leaving no sign of squeeze pressure in the lending market. The put/call ratio at 0.30 is marginally above its 20-day mean of 0.29 — barely one standard deviation higher — which points to options positioning that is calm rather than defensive. The lending market and derivatives market are both saying the same thing: shorts are not pressing an aggressive bet here.
Yet the price action tells a harder story. OLN has fallen 7% in a single session and 8.5% over the past month, closing at $26.76. That decline happened even as short positions were being covered — a pattern that typically signals sellers are not just short-side traders but also longer-term holders reducing exposure. Peers have diverged sharply: DOW and WLK both fell on the day, down 5.6% and 4.6% respectively, while surged 14% on the week, suggesting OLN's weakness is only partly sector-driven.
The analyst community has been broadly constructive in the run-up, with Wells Fargo upgrading to Overweight in early April and lifting its target to $35, while Citigroup and UBS both raised targets to $30 and $29 respectively. The mean target of $26.79 now sits almost exactly at the current price — meaning the Street collectively sees little near-term upside even after a run of positive revisions. The bull case rests on an epoxy supply contract, caustic soda market tightening, and disciplined capacity management. Bears point to a deteriorating EBITDA trajectory, higher maintenance costs from a VCM turnaround, Winter Storm Fern disruptions, and margin pressure in the Winchester segment. EPS momentum rankings sit in the 4th and 5th percentiles over the past 30 and 90 days — the weakest part of the factor profile — while the EV/EBITDA multiple has compressed by about one full turn over the past month to 9.5x.
The print will test whether Olin's operational headwinds are temporary weather-and-turnaround noise, or the leading edge of a deeper margin reset in chlorine and epoxy that the collapsing EPS momentum has already begun to price in.
