Structural Rigidity of Market Expectations: A Mechanism Analysis of Catalysts in Value Investing

When a company’s stock price is undervalued, management could signal to the market—‘We are undervalued’—by repurchasing shares. Yet reality often runs counter: management chooses inaction, preferring to hold cash on the balance sheet at low interest rates rather than risk share buybacks. The reason is pragmatic: if the stock price continues falling after a buyback, management faces accusations of ‘wasting shareholder capital.’ Under the logic of maximizing personal interests, inaction may merely be judged as ‘mediocre,’ whereas action—should it fail—could be branded as ‘dereliction of duty.’ This gives rise to an equilibrium of ‘passive inaction.’ And management’s inaction, in turn, supplies ‘evidence’ for the market’s pessimistic narrative—‘Look, even they don’t believe in themselves; why should we?’ III. The Self-Reinforcing Cycle of Pessimistic Equilibrium These four mechanisms do not operate in isolation; rather, they reinforce one another, forming a self-consistent, pessimistic feedback loop: Pessimistic narrative takes hold → Confirmation bias filters out positive information → Disposition effect locks investors into positions and suppresses trading volume → Herd behavior suppresses independent value judgment → Management, constrained by agency problems, chooses inaction → Signals of improving fundamentals fail to reach price → Price stagnates → This ‘confirms’ the pessimistic narrative → Pessimism intensifies further. Price itself becomes the most powerful amplifier of narrative. Stagnant price is the strongest ‘evidence’ of pessimism. Within this equilibrium, even if fundamentals have begun improving, price will remain stuck at depressed levels unless an external, sufficiently strong force breaks through the cycle. The root cause of systemic undervaluation lies not in the market’s lack of information, but in its entrapment within a structurally dysfunctional response regime. IV. Catalysts: The Sole Key to Breaking the Impasse Within this framework, the role of catalysts becomes exceptionally clear: catalysts are not providers of ‘new information,’ but rather external, coercive forces capable of piercing structural inertia. Catalysts work precisely because they operate simultaneously across four dimensions: Signal Dimension: A catalyst constitutes a high-cost signal. Take share repurchases as an example—when a sound company repurchases shares amid undervaluation, it reflects intelligent capital allocation; when a weak company does so, it amounts to deploying scarce cash to acquire overvalued assets—a value-destroying act. The same action carries vastly different cost structures for strong versus weak firms, satisfying the ‘separating condition’ of signaling theory—weak firms cannot credibly imitate it. Thus, large-scale buybacks serve as a strong signal that directly pierces information asymmetry and confirmation bias. Agency Dimension: A catalyst functions as an external mechanism constraining agency problems. When management returns cash to shareholders via special dividends or buybacks, it directly reduces discretionary free cash flow—alleviating market fears of ‘management misusing funds’—and signals willingness to relinquish control over cash in exchange for shareholder trust. This directly disrupts the ‘inaction equilibrium.’ Psychological Dimension: A catalyst serves as an external event that resets the ‘reference point.’ Events such as two consecutive quarters of earnings exceeding expectations, shifts in industry policy, or major shareholder增持 (increased holdings) break the pessimistic narrative’s anchoring on the reference point, shifting market attention from ‘this company is failing’ to ‘this company may not be as bad as assumed,’ thereby reactivating the price discovery mechanism.

Chemicals Are Next—Will the ‘Chemicals Bull Market’ Arrive?

02 Short-Term ‘Catalysts’ Reinforce the Bullish Narrative Long-term logic sets the direction; short-term events often act as the market’s ‘accelerator.’ Recently, several factors have significantly strengthened bullish sentiment. First is the impact of extreme weather. North America has recently experienced a severe cold snap, causing natural gas prices to surge over 60% in a short period. As both a key chemical feedstock and energy source, soaring natural gas prices directly raise production costs. More importantly, extreme cold may directly disrupt production facilities. The U.S. Gulf Coast—home to the vast majority of the nation’s ethylene capacity and numerous chemical plants—faces heightened risks of equipment failure, pipeline freezing, and logistics disruptions due to low temperatures, fueling market concerns about supply tightness. Such weather-driven supply-risk expectations represent a classic short-term price driver. Second is geopolitical tension providing cost support. Ongoing instability in regions such as the Middle East underpins crude oil prices. As the foundational cost input across the entire energy-chemicals system, persistently firm crude prices lift the overall cost floor for chemical products. Notably, Iran—a major source of China’s imports of methanol and ethylene glycol—has seen escalating tensions, heightening concerns over supply-chain stability and thus boosting market sentiment. The convergence of long-term narratives and short-term catalysts has effectively ignited bullish enthusiasm. 03 Market Rally Exhibits Structural Differentiation—not Broad-Based Gains A closer look reveals that this rally in the chemicals sector is not universal, but displays pronounced structural characteristics. Strong-performing subsectors typically possess distinctive strengths in their supply-demand dynamics. Take PTA and its upstream feedstock PX as examples: the core logic lies in ‘capacity mismatch.’ In 2026, no new PTA capacity is expected to come online, and only minimal new PX capacity may enter operation in the second half of the year. Meanwhile, downstream polyester capacity continues expanding. This creates a mismatch where upstream and midstream supply is constrained while downstream demand grows—providing ample room for price appreciation. The rally in synthetic rubber follows a different logic, centered more on ‘cost-driven’ and ‘supply contraction’ dynamics. Over 70% of synthetic rubber’s production cost comes from butadiene. Recently, domestic plant maintenance and increased exports have tightened butadiene supply and kept prices firm—significantly raising the cost floor for synthetic rubber. Simultaneously, synthetic rubber output declined in December last year. The confluence of rising costs and shrinking supply has driven rapid price increases. This reflects selective capital allocation under current conditions. Rather than buying the entire sector indiscriminately, the market is digging deep into subsectors with the most acute supply-demand imbalances and the sturdiest fundamental logic. This is essentially a ‘structural valuation correction’ grounded in anticipated improvements on the supply side. 04 Several Issues Warrant Attention Although the rally unfolds amid optimistic sentiment, several issues still merit close monitoring. First, the sustainability of cost-side support. The North American cold snap is a transient weather event—the impact will inevitably fade. Once temperatures normalize, natural gas prices will likely retreat, eroding the associated cost support. Crude oil prices also face complex global supply-demand dynamics, rendering their upside potential uncertain. Should cost support weaken going forward, the foundation for chemical product price increases will be tested.
