Hang Seng Index jumped 30% in 2025: here are the top gainers

The Hang Seng Index had a good performance in 2025 as it jumped by 30%, outperforming other top global indices like the S&P 500, Dow Jones, and the Nasdaq 100 Index. It was trading at $25,935 on Monday, up by ~40% from its lowest level in April. This article explores some of the top reasons behind the rally and the top gainers.

Why the Hang Seng Index soared in 2025

The Hang Seng Index, which tracks the biggest companies in China, did well in 2025. First, the rally was because of the ongoing performance in the global equities market, with most indices being in the green. This includes popular indices like the German DAX, the Nasdaq 100, and the TSX Composite. 

Second, the index jumped after Donald Trump announced a trade deal with China in his bid to secure rare earth materials. He slashed tariffs from over 100% to the current 15%. 

Additionally, the index benefited from the artificial intelligence trade experienced this year. That is important as the index is made up of some of the biggest companies in the AI industry, like Tencent and Alibaba. 

The Chinese economy continued doing well, with analysts expecting it to hit the important milestone of 5%. One sign that this will happen is the soaring copper price, which hit a record high of $13,000. Copper is widely seen as the barometer for the global economy.

Top gainers in the Hang Seng in 2025

Most companies in the Hang Seng Index did well this year. China Hongqiao Group stock jumped by 181% this year and was the best-performing company in the index. This increase brought its ten-year gains to over 653% as demand for aluminium continued soaring. This is notable as it is one of the biggest players in the aluminium index.

Zijin Mining Group stock price jumped by 154% this year as the copper and gold prices continued their bull run. Gold more than doubled and moved above the key resistance level at $4,50. Silver price is nearing $80, while other metals it mines continue rising. 

SMIC, one of the biggest chip manufacturing companies in China, soared by 126% this year as the artificial intelligence boom accelerated. It has jumped by over 800% in the last decade. 

Meanwhile, the Pop Mart stock price jumped by 126%, helped by the ongoing labubu craze. However, the stock has plunged by 22% in the last three months as concerns about its demand remained. 

The other top gainers in the Hang Seng Index were companies like Innovent Biologics, Hansoh Pharmaceutical Group, JD Health, and Sino Biopharmaceutical Group. 

Some key companies in the index did well. For example, Alibaba jumped by over 78% as the company’s turnaround strategy accelerated. HSBC stock soared because of the ongoing boom in the banking sector, and as its turnaround continued. Hang Seng Bank also jumped after being acquired by HSBC. 

There were some notable laggards in the Hang Seng Index this year. Meituan’s stock price plunged by 30% this year as the price war with Alibaba and JD accelerated. Li Auto and BYD stocks dropped by double digits as concerns about the Chinese electric vehicle (EV) remained.

Investors are concerned that these companies will see waning demand after many Chinese provinces started to end the subsidies. As such, market participants worry that the companies will see slow growth during the year.

The other top laggards in the Hang Seng Index were Zhongsheng Group, JD.com, New Oriental, China Mengniu Dairy, Longfor Group, and JD Logistics.
