Market Overview

On 7 January 2026, the Shanghai Composite Index opened slightly higher and maintained a positive trend throughout the trading day, reflecting a broader market lift across the three major A‑share indices. The Shenzhen Component Index and the ChiNext Index also opened in the green, recording gains of 0.28 % and 0.36 % respectively.

The daily market movement was supported by a strong performance in the semiconductor sector, particularly within the memory‑chip and advanced packaging segments. The overall electronics industry advanced by 1.25 %, with a net outflow of 3.915 billion yuan in institutional money. While the sector attracted limited capital, 218 constituent stocks received net inflows, most notably North‑Capital Technology, Nanda Optoelectronics, and Changchun Technology.

Semiconductor Highlights

The memory‑chip theme dominated the morning session. Several names achieved significant intraday gains, including:

  • Prune Co., Ltd. – 20‑centimeter daily limit (20 cm) and a 3‑day consecutive limit climb.
  • Jiangbo Long – >10 % intraday rise.
  • Shannon Chip Creation – strong positive momentum.
  • Deminli and Zhao Yi Xian – also posted sizable gains.

These moves were part of a broader rally in the storage‑chip segment, which benefitted from positive sentiment surrounding upcoming consumer‑electronics events such as CES 2026 and the announcement of new AI‑chip platforms by industry leaders.

In contrast, the electronics sector experienced a net outflow of 3.915 billion yuan. Despite this, 38 individual stocks received net inflows exceeding 100 million yuan, with North‑Capital Technology leading the list (13.85 billion yuan) followed by Nanda Optoelectronics (8.71 billion yuan) and Changchun Technology (6.71 billion yuan). Among the outflow side, 35 stocks saw net outflows over 100 million yuan, the largest being Luxshare Precision (1.765 billion yuan), Victory Technology (1.215 billion yuan), and Industrial Fortune Link (898 million yuan).
