2025‑11‑27 – Dosilicon Surges Beyond 15 % to a New All‑Time High

The Shanghai Stock Exchange witnessed a dramatic rally for Dosilicon Co. Ltd. (688110.SH) on the afternoon of 27 November, when the share price leapt more than 15 % and broke its historical peak. Trading volume eclipsed 5.9 billion yuan, underscoring a surge of confidence that appears to be driven by both institutional buying and a broader bullish sentiment in China’s semiconductor ecosystem.

Quantitative Performance

  • Closing price (25 Nov): 118.8 CNY
  • 52‑week high (02 Sep): 136 CNY
  • 52‑week low (05 Dec 2024): 21.9 CNY
  • Market capitalization: 43.04 billion CNY
  • Price‑earnings ratio: –254.69 (negative earnings, a common feature for high‑growth Chinese tech firms)

The 15 % jump pushed the share price above its 52‑week high, positioning Dosilicon as a breakout winner in a market that has been largely range‑bound for the past year. The volume spike of 5.9 billion yuan represents a sharp departure from the typical trading activity for a company with a market cap of this size.

Institutional Momentum

Several independent reports from the same day confirm that the rally was not an isolated incident:

  • Net buying of 3.73 billion yuan was recorded for Dosilicon in the post‑market “龙虎榜” (top‑trading list), a figure that accounts for 6.65 % of the day’s total transaction value for the stock.
  • The “中山东路” trading desk added 1.5 billion yuan in net purchases, further illustrating that active fund managers are positioning heavily for the stock.
  • A broader market‑wide analysis indicated that electronics and semiconductor sectors were among the top recipients of net inflows, with Dosilicon receiving a sizable proportion of that capital.

Macro‑Context: The “Super‑Cycle” in Memory and Storage

The rally can be read as part of a larger trend that has been unfolding over the past weeks. A separate report dated 26 November highlighted that the memory and storage industry is experiencing a “super‑cycle” of price escalation, propelled by escalating demand from artificial intelligence (AI) workloads. In this environment, Chinese firms are accelerating the adoption and supply of domestic memory chips to ensure continuity in the face of global supply constraints.

The increased visibility of Dosilicon in the “龙虎榜” is consistent with a narrative that the company is positioned to benefit from this shift. While the company’s earnings remain negative, the market appears to be pricing in a future where it will capture a larger share of the AI‑driven memory market.

Risk and Outlook

Despite the robust trading metrics, the fundamentals of Dosilicon remain uneven:

  • The negative price‑earnings ratio indicates that the company is still operating in a loss‑making phase, a scenario that is not uncommon for high‑growth Chinese semiconductor firms but warrants caution.
  • The 52‑week range, from 21.9 to 136 CNY, demonstrates a high degree of volatility; a correction could easily erase gains made on 27 November.
  • The lack of a clear earnings turnaround plan and the ongoing global geopolitical tensions in the semiconductor supply chain introduce additional uncertainty.

Nevertheless, the confluence of institutional buying, macro‑sector strength, and a favorable policy environment for domestic chip manufacturing suggests that Dosilicon could sustain momentum if it delivers incremental product and revenue milestones. Investors should monitor the company’s quarterly reports for evidence of revenue growth and cost containment.

In conclusion, Dosilicon’s 15 % surge and record‑breaking volume are emblematic of a sector in ascendance, buoyed by AI demand and a domestic push to secure supply chains. While the stock’s valuation remains speculative, the current market dynamics point to a compelling, if high‑risk, investment thesis.
