Below is a detailed, news‑style look at Sungrow’s stock performance, the drivers behind today’s move, and what investors are watching next.

Turnover had already reached about CNY 65 billion, implying a turnover rate around 2.1% and a market capitalisation near CNY 398 billion. ^[2]

In other words, today’s rally is an extension of a two‑day surge, with Sungrow trading back toward the upper end of its recent range and remaining one of the most actively traded stocks on the ChiNext market. ^[5]

What is driving Sungrow stock higher on 27 November 2025?

Today’s strength in Sungrow’s Class A shares appears to be supported by three main themes:

Heavy mutual‑fund and institutional positioning in the name
Aggressive margin‑financing inflows into the stock ahead of today’s session
Positive sentiment around solar and storage plays, boosted by product and sector news

Let’s unpack each of these.

1. Strong mutual‑fund demand underpins the rally

A cluster of reports from Sina Finance’s fund channel on 27 November highlight Sungrow as a core holding across a wide range of domestic public funds:

Rongtong Fund products collectively hold about 1.58 million shares of Sungrow. ^[6]
CCB Fund (Jianxin) funds hold roughly 3.01 million shares. ^[7]
Guotai Fund products hold about 2.39 million shares. ^[8]
Additional reports flag positions from Xinda Aoya, Huatai Baoxing, China Post Fund and Manulife‑branded funds, each with meaningful positions in the stock. ^[9]

All of these fund notes repeat a similar set of live‑market numbers: by around 10:00 Beijing time, Sungrow’s share price was up 5.09% to CNY 191.82, with turnover of around CNY 65 billion and a market cap near CNY 397.7 billion. ^[10]

The message for the A‑share market is clear:

Sungrow is emerging as a consensus heavyweight across China’s actively managed mutual funds, particularly in new‑energy and growth‑oriented strategies.

That level of institutional sponsorship tends to support liquidity, reduce idiosyncratic volatility, and can amplify price moves when flows into thematic funds turn positive.

2. Margin‑financing surges to the top tier of the market

Beyond long‑only funds, leveraged investors are also piling into Sungrow.

Data from StockStar and CNGold show that on 26 November:

Sungrow recorded a net margin‑financing purchase of about CNY 8.28 billion – placing it third in the entire A‑share market by net financing inflows on the day. ^[11]
Margin balance in the stock reached roughly CNY 135.17 billion, with total margin‑plus‑short balance (两融余额) at about CNY 135.57 billion. ^[12]

On the short‑selling side, Sungrow saw a net short sale of just 0.28 million shares on 26 November, a modest figure relative to its overall share turnover and suggesting that bearish positioning is limited compared with bullish leveraged bets. ^[13]

For today’s session, 21st Century Business Herald notes that Sungrow ranks among the top individual stocks on the market by turnover, alongside other high‑beta names like New Easetech and Zhongji Xuchuang. ^[14]

The combination of peak‑level margin balances and robust day‑trading activity helps to explain the sharp intraday swings within today’s CNY 183–193 range. It also means future moves could be volatile if sentiment shifts and leveraged positions start to unwind.

3. Sector tailwinds: ETFs and solar/storage momentum

Sungrow’s rally is not happening in isolation. Today’s trading shows broad interest in solar and new‑energy themes across China’s equity market:

The ChiNext New Energy ETF (159122) was up about 1.13% by midday, with Sungrow listed among its major holdings, reflecting Sungrow’s importance in the broader new‑energy index basket. ^[15]
A separate PV‑focused ETF (159857), where Sungrow accounts for over 20% of the index weight, also surged in the morning session. The underlying CSI PV Industry Index briefly climbed more than 2%, pushing the ETF toward a potential three‑day winning streak. ^[16]
At the index level, the ChiNext benchmark was up around 0.56% at midday, with more than 3,300 A‑share stocks advancing across the market. ^[17]

Because Sungrow is a top component of PV and new‑energy ETFs and a flagship name on the ChiNext board, passive and thematic ETF inflows can translate quickly into real buying pressure on the stock itself. Today’s synchronized rise in sector ETFs and Sungrow’s own share price underlines that connection.

Product news: Sungrow’s SBH storage system passes UL fire‑safety test

Away from pure market flows, Sungrow’s fundamentals also received a headline boost today.

On 27 November 2025, Sungrow announced via PR Newswire that its SBH residential battery‑storage series has passed the world’s first residential fire test by UL Solutions, an important safety and certification milestone for home energy‑storage systems. ^[18]

While the detailed technical parameters are aimed at engineers and installers, the investor takeaway is straightforward:

UL Solutions is one of the most recognised safety‑testing bodies globally.
Being first to pass a new residential fire‑safety test gives Sungrow a marketing edge with distributors, utilities and end‑customers concerned about fire risks in lithium‑battery installations.
The SBH line targets residential and small‑commercial markets, areas Sungrow has been aggressively expanding in Europe, Australia and the Americas, according to its global news flow and corporate communications. ^[19]

In an environment where energy‑storage safety standards are tightening, especially in developed markets, such an achievement can support higher sales volumes, ease permitting and potentially justify pricing power for premium systems. The timing of today’s stock surge makes it likely that traders are at least partly reacting to the positive optics of this certification.

What does Sungrow actually do?

For readers discovering the stock through today’s move, Sungrow is more than a pure‑play solar inverter maker.

According to company disclosures and third‑party data:

Sungrow researches, develops, manufactures and services new‑energy power equipment, including photovoltaic inverters, wind‑power converters, energy‑storage systems, EV drive systems, charging equipment, hydrogen‑energy equipment and floating PV solutions. ^[20]
Its revenue mix is highly skewed toward storage and solar. Recent fund reports citing company data show:
- Energy‑storage systems: ~40.9% of main business revenue
- PV inverters and other power‑conversion equipment: ~35.2%
- New‑energy project investment and development: ~19.3%
- Other business: ~2.9%
- Power‑plant electricity generation: ~1.8% ^[21]
Headquartered in Hefei, Anhui province, the company operates globally across China, Europe, the Americas, Asia‑Pacific, the Middle East and Africa. ^[22]

Sungrow is listed on the ChiNext market of the Shenzhen Stock Exchange, which is a NASDAQ‑style board for high‑growth, high‑tech A‑share companies. ^[23]

Fundamentals snapshot: revenue, earnings and balance sheet

Based on data compiled by LSEG and reported by Reuters, Sungrow’s recent fundamental performance has been robust: ^[24]

Revenue (2024): about CNY 77.9 billion, up from CNY 72.3 billion in 2023 and CNY 40.3 billion in 2022
Net income (2024): roughly CNY 11.0 billion, up from CNY 9.4 billion in 2023 and CNY 3.6 billion in 2022
Total assets (2024): about CNY 115.1 billion
Total debt (2024): around CNY 15.6 billion, with total liabilities near CNY 78.2 billion

Local‑market quote services indicate a trailing price‑earnings ratio around the high‑20s for Sungrow’s A‑shares, reflecting investors’ willingness to pay a premium for high‑growth new‑energy leaders. ^[25]

Combined with the approximate 130% share‑price gain over the last year, Sungrow’s current valuation embeds strong expectations for continued growth in solar, storage and related solutions. ^[26]

Key risks and issues for Sungrow Class A shareholders

Despite today’s positive sentiment, investors watching Sungrow’s Class A stock should also consider several risk factors:

Valuation risk
With the stock trading near the upper end of its 52‑week range and at a premium multiple to the broader A‑share market, any slowdown in earnings growth, policy disappointment or sector correction could trigger sharp pullbacks, especially given the elevated level of margin financing. ^[27]
Policy and subsidy exposure
Sungrow operates in sectors heavily influenced by Chinese and global energy policies, including grid‑connection rules, renewable subsidies and storage‑safety standards. Regulatory changes can boost or compress margins quickly.
Competition in solar and storage
The company competes with other Chinese and global manufacturers of PV inverters and battery‑storage systems. Pricing pressure, technological disruption or shifts in customer preference (for example, toward alternative chemistries or competitors’ platforms) could impact Sungrow’s market share. ^[28]
Global expansion execution
Sungrow’s growth story increasingly depends on international markets. While certifications like today’s UL fire‑test milestone help, the firm still faces execution risk around local regulations, supply‑chain complexity and geopolitical issues.
Leverage and liquidity dynamics
High margin balances and concentrated institutional ownership can be a double‑edged sword: they support liquidity on the way up, but can also accelerate drawdowns if large funds or leveraged traders reduce positions.

Bottom line: what today’s move could mean for Sungrow investors

On 27 November 2025, Sungrow Power Supply’s Class A shares are delivering a notable outperformance versus the broader Chinese market, powered by:

Strong mutual‑fund positioning and ETF exposure,
Surging margin‑financing inflows, and
A timely product‑safety milestone in its SBH residential storage line.

The stock remains a flagship name for investors seeking exposure to China’s solar and energy‑storage boom, with solid recent earnings growth and a business mix heavily concentrated in high‑growth segments.

At the same time, rich valuations, sector cyclicality, policy sensitivity and leveraged positioning mean that Sungrow’s Class A shares are likely to stay volatile. Today’s rally underlines the market’s enthusiasm for leading renewable‑energy names—but also highlights why risk management and time horizon are crucial considerations.
