Breaking into a stronger performance surge, almost 20 cm!

1. Tongding Interconnection continues to hit the daily limit, lying flat and winning comfortably. [Taogu Ba]
   Philhua, the Q-sector has strengthened accordingly, also surged 12%, eating meat!
   Yuyan New Materials is still at the Solid-State Battery Conference, see if there’s any stimulus, most likely there will still be gains.

Additionally, Shitou Head Shares exited, replaced by Guangliwei, with a slight profit.

2. Quartz sand has completely transformed from photovoltaic cycle stocks to core materials for semiconductors/AI. High-purity quartz sand is the upstream raw material for photovoltaics, fiber optics, semiconductors/Q-bus. AI computing architecture iteration makes high-end materials go from “optional” to “necessary.”
   Shiying Shares is the most core beneficiary, the only domestic company to achieve the full chain of “ore → high-purity sand → quartz products” independently, breaking import monopoly with semiconductor certification.
   Self-produced sand costs only 1/5 to 1/7 of imports, with a gross profit margin over 70%.
   Q-bus materials will be mass-produced by 2026 to position upstream of AI hardware;
   Philhua is second, already in hand, the only domestic quartz material company certified by the three major international semiconductor equipment manufacturers, with three generations of Q-bus approved by Nvidia for Rubin GPU.

3. Upstream silicon lenses for optical modules are in widespread shortage, with 800G-1.6T and even 3.2T optical modules used extensively, with a supply-demand gap exceeding 40%, and the market space in 2027 exceeding 12 billion yuan.
   Juguang Technology is the leader in silicon lenses, acquiring Swiss SMO to master the ion reaction etching technology, the global pioneer.
   Q1 optical communication revenue increased 200% year-on-year.
   Its V-groove is irreplaceable in CPO scenarios, with 36-144 channels in high-channel FAU. Traditional blade processing cannot meet the precision, so Juguang uses LIMO technology to complete multi-channel processing in one go without cumulative tolerance, and is developing detection equipment simultaneously. Customers are likely to purchase in bundles.

4. Commercial aerospace is ushering in intensive launch, recovery, and the imminent landing of SpaceX IPO, serving as major catalysts.
   Storage chips and commercial aerospace are currently the strongest directions.
   Xinwei Communications is the core leader of the sector, with many confirmed logical points that cannot be falsified.
   Electronics Blue Sky is also a key focus.
