A-share midday report: Stocks open lower and climb as tech recovers; robotics awaits returning capital

Why is short-term sentiment still mixed despite the index rebound?

On the morning of 30 October, indices opened lower and rose in choppy trading, gaining further strength toward midday as trading volume increased slightly from the previous day.
The rebound did not eliminate divergence among individual stocks: some stocks that hit their daily upper limits the previous day fell sharply, while some popular stocks trading at high levels also saw delayed declines. Cailian Press believes an afternoon improvement in sentiment will depend on whether individual stocks can reverse their declines.

Tech stocks rebounded modestly, with PCB stocks relatively strong. Jin An Guo Ji was a key stock on Cailian Press's watchlist; optical communications, chips and semiconductors largely followed the recovery.
Capital returned to robotics after divergent trading. Cailian Press continued to regard it as a leading theme and was watching whether Daye Shares could hit its daily upper limit in the afternoon and lift the sector. Commercial aerospace also recovered, with Jiangsu Technology drawing attention for reversing its previous decline.
Pharmaceutical stocks stood out, which Cailian Press attributed to a read-across from US stocks: Eli Lilly reported better-than-expected third-quarter results. Consumer stocks diverged, with baijiu stocks rising at the open, while dividend sectors such as banking fell toward midday.

Henggong Precision, a company closely followed by Cailian Press, reported robotics revenue of 173 million yuan for the first three quarters of 2026, up 1173.73% year on year and accounting for 15.20% of company revenue. Third-quarter revenue was nearly 100 million yuan, exceeding the first-half total.
The company is focusing on core components for robot reducers and precision structural components for humanoid robots. The report says ductile iron can reduce costs by 20% to 30% and weight by 20% to 30% compared with traditional forged steel, meeting the needs of reducer manufacturers.
Huatai Securities estimates that the global market for continuously cast ductile iron used in robot reducers will reach 10.935 billion yuan in 2030, of which 5.072 billion yuan will be attributable to humanoid robot reducers. This market-size estimate provides a reference for assessing material demand.
