Why Chinese MLCC Stocks Are Surging in 2026: AI Demand, Price Spikes, and the Companies Behind the Rally

Chinese manufacturers of multilayer ceramic capacitors (MLCCs)—the tiny ceramic components often called the 'rice of electronics' because they are essential in nearly every electronic device—are riding a historic stock rally in 2026. The primary fuel is relentless global demand for artificial intelligence infrastructure, especially data center and AI server construction, which requires massive quantities of MLCCs to regulate electrical flow .

This surge is not just a stock story; it's a supply-chain phenomenon. In Shenzhen's Huaqiangbei electronics market, MLCC prices have been climbing for months, with quotes reportedly updating as frequently as every 30 minutes, and the rally has been compared to a 'gold-like' surge . Meanwhile, Japanese and South Korean MLCC leaders like Murata are shifting further upmarket into high-end AI server components, which is opening room for Chinese manufacturers to capture more mid-range and high-end orders . Goldman Sachs has characterized the cycle as the 'largest and longest' MLCC upcycle ever , and quarterly net profits at multiple Chinese MLCC firms have surged—in some cases up to 24-fold year-over-year .

Here are the three Chinese MLCC manufacturers seeing the most notable share price gains, with data reported by Iris Deng in Shenzhen on July 29, 2026 .

1. Guangdong Fenghua Advanced Technology (000636.SZ)

Guangdong Fenghua, one of China's leading producers of consumer-grade MLCCs , has been one of the hottest A-share stocks of 2026. Its share price hit the 10% daily trading limit on July 23, July 27, and again on July 29—a pattern traders call '3 days, 2 limit-ups' (三天两板) .

• Year-to-date gain: Approximately +231.76% as of mid-July, with the stock fluctuating more than 200% over 30 consecutive trading sessions .
• 52-week range: An extraordinary CNY 13.79 to CNY 84.00, highlighting the scale of the move .
• Profit: The company's H1 net profit jumped up to 80% year-over-year, and Q2 net profit was expected to increase 104%–138% quarter-over-quarter .
• Catalyst: Beyond AI demand, Samsung Electro-Mechanics' announcement of an additional US$200 million AI server MLCC order on July 23 directly boosted Fenghua and related stocks .

2. Chaozhou Three-Circle Group (300408.SZ / 6951.HK)

Chaozhou Three-Circle is a major manufacturer of MLCCs and optical communication components like ferrules and sleeves used in data centers. It has been one of the largest companies in the rally, and its stock has surged alongside its pursuit of a secondary listing in Hong Kong .

• Year-to-date gain: Surged 87% by early May 2026, and continued to climb through mid-year .
• HK IPO: Passed its HKEX listing hearing in late June 2026, seeking to raise up to US$1 billion (approximately HK$7.83 billion) to fund overseas expansion .
• Profit forecast: Forecast a sharp profit jump for the first half of 2026, with profit attributable to shareholders expected to rise 45% to 65% year-over-year, to about RMB 1.79 billion–RMB 2.04 billion .
• Stock price (HK): Closed at HK$92.45 on July 30, 2026 .

3. Suzhou GYZ Electronic Technology (688260.SH)

Suzhou GYZ Electronic Technology, while a smaller company, has delivered the most extreme percentage gains in the sector. The stock surged 20% in a single day on May 22, 2026, hitting an intraday high of CNY 72.71 .

• 52-week range: The stock's 52-week range widened dramatically, with a low around CNY 15.32–16.40 and a peak high of CNY 139.00–150.00, implying a maximum gain of over 800% from the bottom .
• Recent price: Closed at ¥100.08 on July 31, 2026, after significant volatility .
• Context: Its performance is tied to the broader MLCC theme, though it also participates in other sectors like PCB (printed circuit board) components that benefit from NVIDIA's new product cycles .

Beyond the Manufacturers: Upstream Suppliers and Broader Impact

The rally has not been limited to the MLCC manufacturers themselves. Upstream suppliers in the MLCC supply chain have also seen substantial share price gains . For example, Jiangsu Boqian New Materials, the world's second-largest supplier of MLCC nickel powder (an essential raw material), filed for its own HKEX IPO in the same week as Chaozhou Three-Circle, highlighting the depth of the capital-raising wave . In the A-share market, stocks like Yunzhuang Technology, Torch Electron, Boqian New Materials, and Sinocera Materials have all moved sharply alongside the manufacturers .

The Big Picture: Is This Sustainable?

The fundamental driver—AI server and data center construction—shows no signs of slowing, and the shift of Japanese and Korean manufacturers upmarket provides an ongoing structural opportunity for Chinese firms . However, the stock price moves have been extreme, with multiple companies issuing abnormal trading notices and shares fluctuating more than 200% in a matter of weeks . The 'largest and longest' upcycle label from Goldman Sachs acknowledges the scale of the opportunity but also signals that the cyclical nature of the semiconductor supply chain remains a risk .
