Shanghai, Jan 26, 2026, 07:59 (GMT+8) — Premarket
Piotech, Inc. Class A shares (688072) closed Friday at 376.03 yuan, up 3.3%, after trading between 359.22 and 376.03 yuan on roughly 6.62 million shares. The stock still sits shy of its 52-week peak at 394 yuan, ahead of Shanghai’s reopening after the weekend.
The move is significant as investors watch changes among big holders and boardroom reshuffles in China’s chip supply chain, where funding cues often trigger sharp stock moves. Piotech produces thin-film deposition tools for chip manufacturing, including PECVD and ALD machines, with most sales focused domestically.
A filing on Jan. 23 revealed National Integrated Circuit Industry Investment Fund Co trimmed its Piotech holding to 16.86% from 17.92%, offloading roughly 2.98 million shares through block trades between Jan. 13 and Jan. 22. The disclosure noted the reduction plan remains unfinished.
Shareholders will convene on Jan. 26 to vote on changes to the board, including electing Zhang Jingyi as a non-independent director following a resignation, according to meeting documents. The notice sets the meeting for 2 p.m. in Shenyang, Liaoning province.
Block trades are privately negotiated transactions outside the usual order book, typically used by big holders to shift large volumes. They help limit immediate price swings, but leave investors uncertain about how much stock remains to be sold.
That overhang carries weight for a firm entrenched in China’s crowded chip-tool sector, where wafer-fab spending shifts can quickly sway sentiment. Traders frequently look to domestic rivals like Naura Technology Group and Advanced Micro-Fabrication Equipment to gauge the sector’s mood—even without any new updates from the companies themselves.
Piotech’s stock action late last week left it vulnerable to wider shifts in mainland tech shares, particularly if risk appetite shrinks across the index.
Yet another round of selling from major holders could strain demand, especially if buyers pull back following recent gains. If chipmakers show any signs of delaying tool orders or trimming capital expenditures, equipment stocks could feel the impact fast.
On Monday, traders will zero in on whether Piotech can maintain Friday’s gains once Shanghai opens. They’ll also watch the shareholder vote results closely, along with any follow-up disclosures after the meeting. Block deal activity will be just as crucial as the headlines.
Investors are eyeing April 28 for the upcoming results, eager to get a read on orders and margins following the stock’s recent moves.
