Market Commentary July 27: Indices Edge Up on Mixed Signals, Building Materials Lead
Daily Perspective
On July 27, the three major A-share indices rose in a volatile session, with the building materials and conglomerates sectors leading gains. Trading volume saw a modest increase from the previous day. Overseas, Trump announced a pause in military action against Iran to create room for negotiations. Domestically, industrial enterprise profits for June continued to grow solidly. These three factors—a de-escalation signal in geopolitical risk, rapid growth in industrial profits, and breakthroughs in domestic computing power industry—formed the day's positive backdrop. In the short term, the easing of external pressures could help repair market risk appetite, while improving industrial profit data provides fundamental support. However, the volatility of geopolitical situations and the gradual nature of market sentiment repair mean short-term fluctuations may persist. Looking medium-term, as external uncertainties are absorbed, the market is expected to revert to a structural, fundamentally-driven trend, with potential rotation between tech-growth and dividend-paying sectors. Key future catalysts include the policy tone from the late-month Politburo meeting and further geopolitical developments, with the medium-term structural outlook remaining positive.
Market Drivers
US says it pauses military strikes on Iran. Reports yesterday indicated that the US Ambassador to the UN stated President Trump has paused military operations against Iran to allow more room for diplomatic talks. This followed 13 consecutive nights of US airstrikes. Trump's move signals a willingness to create space for diplomacy, while also acknowledging that further airstrikes would be ineffective without a major ground operation. Trump later told media that dialogue between the US and Iran continues, noting Iran is "serious this time," but also threatening that military action could be "escalated to a higher level" at any time. Analysis: This represents a phased de-escalation signal in the US-Iran conflict. The easing of geopolitical risk is beneficial for a global risk appetite recovery, positively supporting overall A-share sentiment. It could also help alleviate cost pressures on export-oriented manufacturing and downstream industries previously squeezed by high oil prices. However, the threat of escalation remains, meaning geopolitical uncertainty is not fully resolved.
January-June industrial enterprise profits rise 18.7%. Data from the National Bureau of Statistics showed that from January to June, industrial enterprises above a designated size achieved total profits of 3,947.99 billion yuan, up 18.7% year-on-year. Operating revenue was 69.26 trillion yuan, up 6.5% year-on-year, with an operating margin of 5.70%, an increase of 0.59 percentage points. By sector, mining profits grew 33.5%, and manufacturing grew 20.1%. Among major industries, non-ferrous metal smelting and processing profits surged 99.4%, computer, communication, and other electronic equipment manufacturing grew 96.9%, and chemical raw materials and products manufacturing grew 67.8%. In June alone, profits grew 15.1% year-on-year. Analysis: First-half industrial profit growth was strong, accelerating 3.2 percentage points from Q1, confirming a sustained recovery trend. High-tech manufacturing and resource sectors led the growth, but there was significant divergence along the supply chain—mining profits grew 33.5%, manufacturing 20.1%, while electricity and heat power fell 4.2%. Auto manufacturing fell 19.5% and ferrous metal smelting fell 25.0%, reflecting ongoing demand and cost pressures in some mid-to-downstream sectors. Overall, the industrial fundamentals are sound and supportive of the A-share market.
Central bank announces four overnight reverse repo operations. The People's Bank of China announced that it will conduct overnight reverse repo operations on July 29, 30, 31, and August 3, using a fixed rate and quantity-based bidding method, with a total injection of 2.1 trillion yuan. On July 27, the central bank had already conducted a 7-day reverse repo operation of 325.5 billion yuan at an interest rate of 1.40%. The frequency of these overnight operations is double that of the end of June, and the central bank provided advance notice earlier than usual. Analysis: The central bank's early announcement of large-scale overnight reverse repo operations, totaling 2.1 trillion yuan, sends a clear signal of liquidity stability. The doubling of operation frequency compared to end-June and the early communication indicate a more proactive liquidity management approach. This move helps smooth month-end liquidity fluctuations and keeps short-term rates stable around the policy rate. The ample liquidity environment provides a favorable funding backdrop for the A-share market, aiding sentiment stability and supporting the continuation of valuation repair.
