Analysis of Changelight (300102)'s Strong Performance: Rising Volume and Price Driven by Commercial Aerospace Concept

Changelight has recently become a market focus, the result of resonance among multiple factors.

is the most direct catalyst: on January 8, it hit the 20% daily limit-up in about 7 minutes before market close, with transaction volume reaching RMB 6.352 billion; on January 9, it hit the daily limit-up again (RMB 37.43, 20.01% gain), and transaction volume climbed to RMB 8.551 billion [1][2]. Data from the Dragon and Tiger List shows that four institutional seats bought a total of RMB 126 million, and hot money, institutions, and foreign capital all showed net buying trends, with main funds recording a single-day net inflow of over RMB 700 million [2][3].

is the core logic supporting the company’s valuation. Changelight is the only domestic enterprise capable of mass-delivering epitaxial wafers and chips of gallium arsenide solar cells for satellites. Its products have been applied to more than 20 in-orbit satellites including the G60 Qianfan Constellation, State Grid Constellation, and Satellite Network Experimental Satellite, with a market share of over 60% [4]. China plans to launch more than 13,000 low-orbit satellites from 2025 to 2030, but only less than 200 have been launched so far, creating a huge demand gap. The company has locked in market orders of over RMB 2 billion, with revenue from this business set to double to RMB 120 million in 2025 and expected to exceed RMB 500 million in 2026 [4].

provides fundamental support. According to the Q3 2025 financial report, the company achieved revenue of RMB 2.75 billion, a year-on-year increase of 65.80%; net profit of RMB 87.9496 million, a year-on-year increase of 56.01% [2][5]. Revenue from the Mini LED backlight business surged 402%, Mini RGB business grew 57% year-on-year, and the traditional RGB small-pitch display holds a market share of over 30%. The simultaneous growth of multiple business segments verifies the success of the company’s strategic transformation from a traditional LED manufacturer to a dual-driver model of ‘commercial aerospace + high-end display’.

From a technical perspective, Changelight shows a typical pattern of rising volume and price. The current price is RMB 38.89, about 13% away from the 52-week high of RMB 44.66, and is in a historical high range [0]. The 20-day moving average is at RMB 26.50, and the current price is much higher than the moving average, showing a strong bullish arrangement. In terms of trading volume, 274 million shares were traded on the day, a 137% increase compared to the average daily volume of 193 million shares in the past 20 trading days, indicating extremely active trading [0].

Looking at the gain cycle, the 5-day gain is 55.50%, 1-month gain is 47.76%, 3-month gain is 220.61%, and 1-year gain is 288.12% [0]. The short-term gain is huge, so investors need to be alert to the risk of a pullback caused by profit-taking. The daily volatility reaches 7.42%, making it a high-volatility stock with both risks and opportunities.

The company’s fundamentals are characterized by the coexistence of high growth and high valuation. The total market value is RMB 34.97 billion, and the P/E ratio is as high as 259.27x, far exceeding the industry average [0]. ROE is 3.23%, reflecting that the company is still in a period of high R&D investment; net profit margin is 4.09%, which is in an improving trend. The current ratio is 1.61, indicating good short-term solvency [0].

In terms of business structure, the company has formed four core growth drivers:

benefit from the explosive demand for satellite launches; benefits from the expansion of new application scenarios such as in-vehicle displays and AR/VR; meet the demand for next-generation 1.6T optical modules and align with the development opportunities of AI data centers; have 10G/25G products sent for sample verification, and 50G/100G products have entered the tape-out phase [2][5].

The investment logic of Changelight spans multiple high-growth tracks, forming a unique triple narrative of ‘commercial aerospace + computing infrastructure + new display’. This multi-track positioning allows the company to gain capital market attention and capital allocation in different industrial cycle stages.

From the perspective of industrial development rhythm,

is at a turning point from concept verification to large-scale constellation networking. The successful maiden flight of Zhuque-3 in December 2025 marks a substantive breakthrough in China’s commercial aerospace large-scale constellation networking technology [2]. The construction of low-orbit satellite constellations has entered an acceleration phase, and the company, as a core supplier, is expected to continue to benefit.

has spawned demand for optical interconnection in data centers, and VCSEL chips have become core components of 1.6T optical modules. Changelight’s technological breakthroughs in this field enable it to share in the high-speed growth of the AI industry chain.

The company’s strategic transformation has industry demonstration significance. The traditional LED industry is facing overcapacity and price competition pressure, and Changelight has successfully achieved a revaluation by expanding into high-end application fields. This transformation path may provide a reference for other LED enterprises.

In terms of shareholder structure and governance, Hejun Zhengde Fund has pledged not to reduce its holdings by the end of 2025, demonstrating industrial capital’s confidence in the company’s long-term development [4]. Hong Kong Securities Clearing Company Limited has newly established a position, indicating increased attention from foreign capital to the company. Chairman Li Minhua (born in the 1980s) has received an annual salary of only RMB 120,000 for two consecutive years, reflecting a pragmatic governance style [4].

is the most prominent current risk factor. The 259x P/E ratio has fully reflected the market’s optimistic expectations for the future; if actual performance falls short of expectations, there will be great pressure for valuation regression [0]. In the short term, the nearly 50% gain in one month has accumulated a large number of profit-taking positions, and a pullback caused by profit-taking may occur at any time.

also deserves attention. The market has high expectations that the company’s net profit will exceed RMB 1.5 billion in 2026, but the commercial aerospace business relies on national launch plans, and there is a possibility that progress will fall short of expectations. Risks of technological iteration and intensified industry competition also need continuous tracking.

lie in the continued fermentation of sentiment in the commercial aerospace sector. If there are subsequent catalysts such as satellite launches or constellation networking, the stock price may challenge the previous high of RMB 44.66.

come from order fulfillment and performance verification. If the 2025 annual report and 2026 Q1 report can verify the high-growth logic of the commercial aerospace business, the valuation is expected to gain support from performance digestion.

are closely related to the overall development of China’s commercial aerospace industry. If the launch plan of 13,000 low-orbit satellites is implemented as scheduled, the company, as a core supplier, will continue to benefit.

Based on a comprehensive assessment, Changelight is a

target. For investors with a higher risk appetite, they can participate moderately on the premise of setting stop-losses. For investors with a lower risk appetite, it is recommended to wait for a pullback to around the 20-day moving average before considering positioning. The current valuation has fully reflected optimistic expectations, so it is recommended to remain rational and avoid chasing high prices.

Changelight’s strong performance is the result of the superposition of four factors:

. As the absolute leader in domestic commercial aerospace gallium arsenide batteries, the company occupies a core link in the construction of low-orbit satellite constellations, and multiple business lines such as Mini LED and VCSEL are growing simultaneously, providing certain fundamental support.

: Strong resistance level at RMB 44.66 (52-week high), current price at RMB 38.89, strong support level at RMB 37.00, key support level at RMB 33.90.

: 40% probability of continued strength (continue to rise with increased volume to challenge the previous high), 45% probability of consolidation (stabilize after a short-term pullback to digest profit-taking positions), 15% probability of a deep pullback (a pullback of more than 10% due to fading sentiment).

: Performance verification in the 2025 annual report, progress of commercial aerospace order fulfillment, and business progress of VCSEL and optical communication chips.
