Citi's Quant Team this week identified Ecovyst (NYSE:ECVT), RPM International (NYSE:RPM) and Linde (NASDAQ:LIN) as the most crowded long positions within its chemicals coverage, according to a positioning analysis released by the firm. The crowding composite used in the analysis incorporates five distinct factors - most crowded factor, relative historical valuation, short interest ratio, sentiment and macro exposure - to gauge investor positioning.
Among polyethylene producers, Dow (NYSE:DOW) and Westlake (NYSE:WLK) advanced during the week. Citi's note attributes those moves to lower short interest and improved sentiment amid rising US-Iran tensions. In Dow's case, the company also raised its second-quarter 2026 EBITDA guidance, citing stable demand for polyethylene.
Despite some names attracting long interest, Citi reports that average long crowding across its chemicals coverage declined by roughly 3% week-over-week. By contrast, average short crowding increased by approximately 5% over the same interval.
On the short side, PPG Industries (NYSE:PPG), Sherwin-Williams (NYSE:SHW) and Eastman Chemical (NYSE:EMN) are now listed as the most crowded shorts in Citi's coverage universe. The list of most debated names - determined by the sum of long and short composite scores - includes Axalta Coating Systems (NYSE:AXTA), Sherwin-Williams and Linde.
Looking at changes in investor positioning over the past month, Citi notes that several stocks moved toward greater bullishness. Axalta, Dow, H.B. Fuller (NYSE:FUL), Huntsman (NYSE:HUN), RPM and Westlake showed positive change in long crowding alongside negative change in short crowding, reflecting increased net long positioning.
However, Citi also highlights that a majority of the companies it covers across chemical sub-sectors currently sit in a more bearish camp, characterized by negative long crowding change and positive short crowding change.
In the bank's latest screening exercises, RPM and Sherwin-Williams surfaced as attractive large-cap oversold names. By contrast, FMC (NYSE:FMC) screened as a less attractive large-cap crowded short. Citi continues to carry Buy ratings on both Axalta and Sherwin-Williams.
Contextual notes - The composite methodology and the weekly changes in crowding metrics highlight where investor positions are concentrated and where sentiment and short interest shifts are affecting relative positioning within the chemicals sector. The findings show a mix of concentrated long exposure in select names, pockets of buying in polyethylene producers, and increased short-side concentration among paint and specialty chemical names.
