Morgan Stanley has flagged Sumitomo Chemical (4005), Mitsui Chemicals (4183) and Asahi Kasei (3407) as preferred picks in the petrochemical majors group. The bank points to improving sector sentiment driven by policy moves in China and signs of naphtha cracker downsizing in South Korea, even as demand and ethylene utilization remain subdued and recovery momentum is expected to be muted.

Key Points

  • Morgan Stanley retains an attractive view on petrochemical majors, identifying Sumitomo Chemical (4005), Mitsui Chemicals (4183) and Asahi Kasei (3407) as overweight picks.
  • Improving sentiment is attributed to China's anti-involution policies and signs of naphtha cracker downsizing in South Korea, which the firm says make further downside in Asia petrochemical prices and spreads less likely.
  • Despite the positive signals, demand remains weak and ethylene utilization rates are low, with recovery momentum expected to be limited; implications touch petrochemicals, agrochemicals, pharmaceuticals and plastics markets.

Morgan Stanley continues to view the petrochemical majors as an attractive sector for investors, identifying three companies it believes offer compelling risk-reward profiles even amid persistent sector headwinds. The bank's constructive stance reflects a combination of improving market signals in Asia, low current investment activity and what it considers generally undervalued equity prices across the group.

Market backdrop

While demand conditions are still described as weak and ethylene utilization rates remain low, Morgan Stanley highlights a number of developments that have shifted sentiment. The firm's research points to China's anti-involution policies and indications of naphtha cracker downsizing in South Korea as contributors to a more encouraging overall tone in the petrochemicals complex. According to the bank, Asia petrochemical prices and spreads are unlikely to move materially lower from current levels, although the pace of recovery is not expected to be strong.

The firm also notes recent episodes of price volatility tied to developments in the Middle East. Those swings have complicated the near-term outlook, but have not, in Morgan Stanley's assessment, erased the potential for selective opportunities given low investment indicators and broadly depressed share valuations. Industry reorganization, the bank adds, appears to be gathering pace and could offer additional structural support to the sector over time.


Three preferred names

Morgan Stanley has assigned overweight ratings to three petrochemical majors it regards as attractive picks under the current market backdrop:

  • Sumitomo Chemical (4005) - The bank highlights Sumitomo Chemical's strategic emphasis on accelerating expansion in agrochemicals and IT-related businesses and views the company's resource allocation as investment-friendly. Morgan Stanley points to a V-shaped recovery in earnings at Sumitomo's pharmaceutical subsidiary as a positive element in the group thesis. The company disclosed a net loss of ¥311.8 billion for the 2023 fiscal year and has announced plans to reduce its workforce by 4,000 roles globally. After those results, Mizuho Securities revised its rating on Sumitomo from Buy to Neutral.
  • Mitsui Chemicals (4183) - Rated overweight by Morgan Stanley, Mitsui Chemicals is singled out as positioned to benefit from the gradual stabilization in the sector. The company experienced a 45.4% fall in net profit for the fiscal year ending March 2024 and has entered a partnership with Teijin to develop and commercialize biomass-derived plastics, a strategic development cited in the firm's assessment.
  • Asahi Kasei (3407) - Also rated overweight, Asahi Kasei rounds out Morgan Stanley's top trio. The bank expects the company to gain from the sector's valuation characteristics and any improvement in underlying fundamentals.

Investment thesis and caveats

Morgan Stanley's overweight recommendations reflect the view that these three companies present attractive upside potential relative to the risks currently priced into the market. The firm emphasizes that, despite weak demand and low ethylene utilization, market dynamics in Asia and signs of slower capacity additions have reduced the likelihood of further substantial downside in prices and spreads.

At the same time, the bank signals caution: recovery is expected to be limited in speed, recent geopolitical-linked price spikes have heightened volatility, and investment indicators remain suppressed. These elements underpin Morgan Stanley's selective approach - favoring companies it sees as having clearer strategic direction, valuation support and business-specific catalysts that could deliver a more favorable risk-reward outcome.


Bottom line

Morgan Stanley's analysis highlights Sumitomo Chemical, Mitsui Chemicals and Asahi Kasei as its preferred ideas within the petrochemical majors, balancing an improved sector mood against persistent demand and utilization challenges. The bank's stance is that industry reorganization and constrained investment, combined with company-specific strategic moves, could underpin a more constructive environment for select equities in the group.

Risks

  • Persistently weak demand and low ethylene utilization rates could constrain industry recovery and corporate earnings - impacting petrochemical and related downstream sectors.
  • Price volatility linked to geopolitical developments in the Middle East introduces uncertainty for petrochemical feedstock and product pricing, affecting margins across chemical producers.
  • Low investment indicators and muted recovery momentum mean that fundamental improvement may be slow, leaving equities exposed until industry reorganization or demand improves.
