Shanghai, Jan 20, 2026, 10:22 (CST) — Regular session
- Xi’an ESWIN Material Technology’s A-shares gained roughly 1.4% in morning trading
- The shift followed stronger sentiment in STAR Market chip stocks
- Traders are eyeing upcoming policy clues tied to speculation and liquidity
Shares of Xi’an ESWIN Material Technology Co., Ltd. (688783) climbed 1.38% to 27.11 yuan in Shanghai’s morning session, starting off at 26.30 yuan. The stock peaked at 27.60 yuan and dipped to 26.30 yuan during the trading period. ESWIN Material specializes in 12-inch silicon wafers—polished, epitaxial, and test types—essential for chip manufacturing. 1
The gains come amid ongoing jitters in China’s onshore market, where regulators are cracking down on fast-money trading after several sharp, theme-driven swings. The China Securities Regulatory Commission has ordered brokers to pull client-dedicated servers from exchange data centers, a direct hit on high-frequency traders who depend on speed advantages. “They do want to keep the markets focused on investment, as opposed to speculation,” said Shane Oliver, chief economist at AMP. 2
Chip-related stocks grabbed attention again Tuesday as early trading saw flows head into STAR Market semiconductor plays. A STAR Market chip ETF rose alongside its index, boosted by notable gains in chip design and storage names. Among the biggest index components are foundries and upstream materials suppliers like Shanghai Silicon Industry. 3
Beyond China, attention has turned to the memory supply chain following Micron’s announcement that it will acquire Powerchip’s P5 fab in Taiwan for $1.8 billion. The deal is set to boost DRAM wafer capacity starting in the latter half of 2027. Research firm TrendForce noted this move could increase Micron’s advanced-process DRAM output and reshape the supply landscape down the line. 4
Trading in ESWIN Material has mainly revolved around positioning instead of new company-specific news. Investors see upstream wafer stocks as a leveraged indicator of domestic fab utilization and the wider semiconductor cycle.
Wafers kick off the chipmaking process, and demand often appears steady—until it suddenly shifts. When memory and foundry clients tweak their capacity plans, wafer orders typically respond after a delay, with the market usually pricing in that risk well in advance.
Beijing is caught in a policy tug-of-war. It aims to bolster domestic supply chains but has voiced concerns about frothy, rapid-fire trading that could unsettle prices.
The downside is straightforward: if regulators clamp down more on leverage and program trading, risk appetite could evaporate fast in high-beta tech and semiconductor stocks. A slip in domestic demand or fresh pricing pressure along the wafer chain would shake sentiment first, dragging fundamentals down afterward.
Traders will keep an eye on whether the morning rally lasts into the afternoon, a frequent weak spot for momentum plays in A-shares. Liquidity tends to dry up, and stocks can gap sharply on modest volume.
Money conditions continue to play a key role behind the scenes. On Tuesday, China held its benchmark loan prime rates steady — the one-year at 3.0% and the five-year at 3.5% — shifting attention to the timing of further easing rather than its likelihood. The next rate setting is scheduled for Feb. 20. 5
