Market Activity on 2026‑07‑03

During the trading session on 3 July 2026, Defu Technology experienced a gain of more than 8 %, placing it among the best performers in the Chinese equities market that day. The rally was part of a broader surge in the defense‑technology sector, where several stocks reached record highs. Notable peers that day included:

  • Best Science – up more than 10 %
  • Keixiang Shares – up more than 10 %
  • Longda Shares – up more than 10 %
  • Feiwo Technology – up more than 10 %
  • Hangfa Technology, Chengchang Technology, and Feilong Shares – all hit the daily limit (涨停)

The momentum was attributed to expectations that the 15‑year “十五五” defence planning and the approaching 2027 centenary of the armed forces will increase order certainty and expand defence spending and export opportunities.

Sector‑Specific Drivers

Defense‑Technology Expansion

Analysts from Kaishuan Securities predict that the 15‑year defence plan and the 2027 centenary will create a favorable environment for commercial aerospace, unmanned aircraft, stealth materials, and missile and ground‑unmanned equipment. The sector benefits from equipment upgrades and increased consumable demand, and geopolitical tensions are expected to sustain defence spending growth.

Copper‑Foil / Copper‑Plated Board Theme

In a separate market movement, copper‑foil and copper‑plated board stocks rebounded. Defu Technology was among the leading gains, joining peers such as NuoDe Shares, FangBang Shares, ShengYi Technology, HongHe Technology, BaoDing Technology, and HaiXing Shares. The rally followed a notable limit‑up by NuoDe Shares, suggesting that supply chain concerns in the battery and semiconductor sectors may be easing.

Impact of Apple’s Production Plans

Apple’s recent announcement to increase its foldable iPhone production target to approximately 10 million units has intensified demand for components across the supply chain. While Defu Technology’s primary products are not explicitly linked to Apple, the broader market for copper‑foil and related materials could benefit from the heightened component demand, potentially supporting future revenue growth for firms in this segment.

Battery‑Sector Dynamics

The battery sector remains volatile. On 1 July 2026, the battery ETF HuiTianFu (159796) fell by 2 %. Defu Technology’s shares rose more than 7 % during the same session, reflecting sectoral optimism around upstream chemical and material providers. In contrast, major battery manufacturers such as SunPower Energy and others experienced sharp declines, highlighting the differentiated impact of policy concerns (e.g., proposed restrictions on foreign inverters) on the upstream versus downstream segments of the battery supply chain.

Summary of Trading Performance

  • Closing Price (2026‑06‑30): 155.02 CNY
  • 52‑Week High: 178.88 CNY
  • 52‑Week Low: 23.33 CNY

  • Performance on 2026‑07‑03: Gain > 8 % in a session marked by defensive‑sector strength and a copper‑foil rebound

Defu Technology’s recent gains are supported by favourable sector dynamics in defence technology and copper‑foil manufacturing, alongside broader market enthusiasm for supply‑chain components tied to emerging consumer electronics demand.
