Summary · why it matters
On the morning of September 2, the A-share market fluctuated and adjusted, with the ChiNext Index briefly falling more than 2 percent. However, the aerospace and defense sector bucked the trend and strengthened. Shengnan Technology rose more than 26 percent, Beifang Changlong and Tianqin Equipment rose more than 10 percent, and Inner Mongolia First Machinery, Jianshe Industry, and Great Wall Military Industry hit the daily limit. On the news front, according to CCTV News, the US military launched a new round of strikes against targets inside Iran, and Iran retaliated by shooting down a US MQ-9 drone, escalating geopolitical tensions. AVIC Securities believes that the defense sector is still in a valuation repair window, with limited downside and upside elasticity depending on the realization of catalysts and order recovery, and holds an optimistic judgment for the second half of 2026.
