Short sellers are returning to OLN just as the Street is lifting its price targets — a divergence that defines the week's setup.
Short interest has climbed sharply back toward the high end of its recent range. At 10.5% of the free float as of May 12, it is up 13% on the week. That reverses a sustained de-risking: shorts had pulled back from above 13% in early April all the way to around 9.3% by early May, covering nearly a third of positions over six weeks. The week's rebuild, adding roughly 1.3 million shares in two sessions, suggests that rally — which came after Q1 earnings on May 7 — has attracted fresh bearish conviction. The stock fell 6.8% on earnings day itself, then bounced 6.2% the following session, a violent two-day swing that may have unsettled both sides. Despite the week's short rebuild, the borrow market is not pricing in meaningful stress. Cost to borrow is only 0.51%, up about 17% on the week but still a low absolute level. Availability remains comfortable, meaning there is no squeeze pressure underpinning the position rebuild — this looks like a directional bet, not a forced technical move.
Options positioning is edging in a more defensive direction, though it is not yet alarming. The put/call ratio is running at 0.31, slightly above its 20-day average and sitting around 1.6 standard deviations above the norm. The 52-week high is 0.73 — well above where it is now — so the options market is cautious rather than panicked. Combined with the short rebuild, the overall positioning picture is: bears are rebuilding exposure into post-earnings price strength, but they are not pressing the trade hard.
The analyst community, meanwhile, has moved decisively in the other direction this week. Goldman Sachs raised its target from $22 to $31 on May 12, maintaining Neutral. UBS followed on May 13 with a lift from $29 to $31, also Neutral. Morgan Stanley raised its Underweight target from $18 to $22. Truist moved from $20 to $26 on Hold. These moves follow a Wells Fargo upgrade in early April to Overweight with a $35 target. The direction of travel is clearly higher — targets have been moving up across the board since March. But the distribution matters: even after the upgrades, the consensus clusters around Neutral, with only one Overweight among the active coverage. The mean price target of $28.57 is modestly above the current $27.59, offering a thin implied upside. Morgan Stanley's $22 Underweight target, just raised from $18, sits well below the pack — the bears on the Street are still present, even if becoming a smaller minority.
The bull case centres on tightening caustic soda markets and the expected recovery in Olin's Epoxy segment from restructuring and efficiency gains. The bear case points to recession risk in Europe weighing on EDC and epoxy, along with near-term profitability pressure from higher energy costs and Winchester margin challenges. At 8.65x EV/EBITDA — down from around 10.2x thirty days ago — the valuation has compressed meaningfully, even as the stock has pulled back 4.7% over the month. The EPS surprise factor scores in the 91st percentile, suggesting the company has a strong recent history of beating estimates, but the 30-day EPS momentum rank sits at zero — the forward earnings revision picture has deteriorated sharply. That combination of strong historical delivery and weakening near-term estimates captures the ambiguity neatly.
The largest holder, Hotchkis and Wiley, added 2.6 million shares in its last reported period and holds 13.4% of the company — a substantial conviction long. Orbis Investment Management added 3.1 million shares as of its December filing, though that data is a few months stale. The ownership base is heavily value-oriented. Insider activity is dominated by awards and routine tax-related sells, with no material discretionary buying or selling in recent weeks.
The next earnings date is July 30. Between now and then, what matters most is whether the short rebuild reflects genuine conviction about the commodity cycle deteriorating further — particularly in caustic soda and epoxy — or whether it fades as it did across April, when covering dominated for nearly four straight weeks after a prior peak above 13%.
