How should we view the A-share market performance on March 31, 2026?

Today, I chatted with neighbors in my residential community about investing. One neighbor remarked that China’s A-share market is merely a ‘copycat’ of Wall Street. Hearing this, I felt an inexplicable sense of absurdity and irony. Don’t assume that because U.S. stocks fall, the A-share market must follow suit—and therefore conclude that the A-share market is just a lapdog trailing behind Wall Street. On the contrary, the A-share market is *extremely* idiosyncratic. I’m not saying the A-share market is particularly strong—rather, its internal logic of operation is fundamentally *unrelated* to external markets. U.S. stocks may be falling, but they clearly feature a coherent thematic driver: stocks benefiting from geopolitical conflict—especially oil & gas and chemicals. The most typical examples are oil & gas and chemical stocks, both of which have risen steadily. Here’s Occidental Petroleum: Here’s Chevron: Chemical stocks follow the same pattern. Here’s Dow Chemical: Here’s LyondellBasell: Here’s Westlake Corporation (WLK): All are foundational chemical producers focused primarily on olefin-based products. Compared with leading domestic chemical firms, these U.S. companies show no significant advantage—or disadvantage—in terms of cost structure, pricing power, or fundamental quality. In fact, most U.S. chemical stocks remain unprofitable. If you strictly assess fundamentals, these U.S. chemical enterprises are objectively *inferior* to China’s coal-chemical leaders. So what happened? Despite both markets experiencing broad declines, U.S. oil & gas and chemical stocks carved out *independent*, upward trajectories. Meanwhile, their A-share counterparts suffered losses on *both* sides—down when the market fell, and *still down* when the sector rallied elsewhere. Thus, although the U.S. market’s overall decline was deeper, it actually offered *more* profit opportunities than the A-share market. Because the U.S. market has a clear theme: energy & chemicals strong, tech weak. You don’t need to obsess over the index—you just need to latch onto that theme. But what about the A-share market? Don’t be misled by the fact that its index fell slightly less than the U.S. market’s. For an entire month, the A-share market has been wildly volatile—yet hasn’t produced *a single coherent, sustained theme*. Oil & gas stocks readily follow the broader market *down*, but refuse to rally *up* alongside it. Coal-chemical stocks surged for a few days—only to get slammed downward immediately after. Photovoltaics finally stabilized—only to suffer delayed downside. Any stock daring to lead gets ruthlessly punished. There simply isn’t a continuous, cohesive trend. Today, speculation even shifted abruptly to a one-off concept like ‘underwater high-speed rail’—pure hit-and-run trading. Right now, the A-share market cannot meaningfully be viewed as a reflection of U.S. markets. Because when external markets shine under the ‘coal-oil-gas-electricity’ narrative, the A-share market *ignores* it. U.S. oil & gas and chemical stocks rose steadily—yet A-share counterparts followed *only on the downside*, not the upside. Conversely, when external markets collapsed under the ‘AI-tech’ narrative, the A-share market stubbornly held up. Even as the Philadelphia Semiconductor Index plunged, institutional players today attempted to lift Yizhongtian—nearly pulling the ChiNext index into positive territory. This extreme individualism ultimately leaves *everyone* without profits. If you hold coal-oil-gas-electricity stocks, domestic capital simply won’t buy in: oil prices rise? The A-share sector rises only 2–3% half-heartedly; oil prices dip slightly? It immediately collapses. What about tech or semiconductors? That doesn’t work either—because while A-share tech appears relatively strong versus overseas peers, that ‘strength’ merely means it fell *less* than U.S. tech during its crash. You still lose money.

Energy stocks plummeted while chemical stocks surged! What’s the most reliable profit-making logic amid such rotational market dynamics—once understood and mastered?

The strength of this market rebound far exceeded many investors’ expectations, and overall market sentiment has clearly improved and recovered. Against this backdrop of broad-based optimism, today’s A-share market delivered a highly instructive *divergent* performance: the energy sector sharply retreated, while the previously dormant chemical sector surged逆势—creating a stark ‘ice-and-fire’ contrast that served as a practical masterclass for all investors. Such divergence is easy to understand. As external developments gradually settle—particularly with U.S. midterm election results becoming clearer and Middle East conflict risks continuing to ease—market expectations for rising international oil prices have receded. Weaker oil-price expectations weigh on the energy sector (which benefits from high oil prices), yet simultaneously deliver tangible tailwinds to the broader chemical industry—thus explaining today’s diametrically opposite price action. Reviewing this round of structural market moves, I’ve grown increasingly convinced of one core investment principle: the essence of investing lies *not* in precisely predicting market direction—but in possessing mature, adaptable response frameworks that allow us to stay diversified *regardless* of how market winds shift. A common pitfall among investors is overconcentrating positions—betting heavily on a single stock or sector. While such bets yield impressive returns during one-sided rallies, they leave investors extremely vulnerable once market style rotates or trends reverse—often resulting in total losses. Truly long-term, stable investing never pursues explosive gains from any single move; rather, it seeks *repeatable, consistently executable* returns. Balanced allocation—mixing core holdings with tactical exposures—is the essential key to navigating volatile, range-bound markets. Since this rebound began, many investors have fallen into the same operational dilemma: faced with improving market conditions, they’re unsure whether to take profits on existing positions whose underlying catalysts haven’t yet materialized—or whether to exit entirely, fearing a bear-market collapse. In fact, many here commit a conceptual error: conflating *profit-taking during a rebound* with *bear-market risk aversion*. These are two entirely independent concepts—and confusing them easily leads to counter-trend, suboptimal decisions. Profit-taking after a rebound isn’t about fearing a bear market—it’s about rational portfolio optimization for overvalued assets. ‘Selling high and locking in gains’ applies specifically to securities that have surged sharply in the short term, whose valuations are already stretched, whose fundamentals lack near-term catalysts, and whose upside momentum is unsustainable. Take the soda ash sector, for example: industry earnings show no genuine turnaround, and share prices have languished in a prolonged bottom-range consolidation—lacking any foundation for sustained strength. Swapping such positions during a rebound—reallocating capital toward higher-value opportunities—is rational portfolio rebalancing—not panic-driven top-selling. The core rationale for selling is *overvaluation and poor risk-reward*, not bearish macro sentiment. Conversely, ‘bear-market mudslides’ reflect short-term emotional contagion—not a valid reason to sell individual stocks. When entire sectors weaken, pessimism spreads rapidly, dragging down most stocks—even fundamentally sound ones. This is common in choppy, range-bound markets. Yet broad-based weakness does *not* mean every holding should be blindly liquidated. Especially for undervalued, low-position stocks whose investment thesis remains unfulfilled—they aren’t liabilities, but valuable shock absorbers in volatile markets. During bearish phases, most assets face pressure—but high-quality, undervalued names have limited downside, while their intrinsic value continues growing steadily. Once market sentiment recovers, these positions often rebound with far greater elasticity than overextended thematic stocks—delivering true ‘offensive upside and defensive resilience’.
