In the world of global investing, the narrative often revolves around the tech giants of China, with names like Alibaba, Tencent, and DeepSeek dominating headlines. But what many investors overlook is the profound influence of 'Old China' on the country's core domestic equity benchmarks. These state-owned banks, energy giants, and insurers form the backbone of China's economy, and their dominance in the CSI 300 and FTSE China A50 indexes is a testament to their enduring importance. In this article, I'll delve into the reasons behind this divide and explore the implications for investors. Personally, I find this topic particularly fascinating because it challenges the conventional wisdom that China's stock market performance mirrors the fortunes of its global technology names. What makes this especially intriguing is the structural economic reasons behind the dominance of 'Old China' in mainland equity indices, despite the rise of Alibaba, Tencent, and AI stocks. From my perspective, understanding this divide is crucial for investors seeking real exposure to China's domestic equity market. The CSI 300 and FTSE China A50 indexes, both market-capitalization-weighted, offer a window into the tangible economy, with the financial sector accounting for a significant share. The top ten largest CSI 300 companies by weight are a who's who of state-owned institutions, including the Industrial and Commercial Bank of China (ICBC), PetroChina, and Ping An Insurance. These companies, not the technology platforms dominating Western headlines, are the true drivers of China's economy and, by extension, its stock market. One thing that immediately stands out is the misconception that China's stock-market performance mirrors the fortunes of its global technology names. What many people don't realize is that Alibaba and Tencent are not listed on mainland A-share exchanges, and their dominance is felt primarily in offshore markets. This raises a deeper question: How do investors navigate the divide between the offshore and onshore markets in China? In my opinion, the answer lies in understanding the structural income advantage of onshore equities, particularly in the energy and financial sectors, which offer attractive dividend yields. This, combined with the regulatory evolution and the central government's focus on energy security and grid capacity, provides long-term revenue visibility for state-owned companies. If you take a step back and think about it, the dominance of 'Old China' in mainland equity indices is not just a reflection of the country's economic structure but also a testament to the resilience and stability of its state-owned institutions. The financial sector, in particular, plays a pivotal role, with the Big Four state banks functioning as instruments of industrial policy. This is a critical detail that investors should be aware of, as it highlights the importance of state-owned banks in China's economic landscape. In conclusion, the dominance of 'Old China' in mainland equity indices is a fascinating and complex phenomenon. It is a reflection of the country's economic structure, the resilience of its state-owned institutions, and the regulatory environment. For investors, this means that understanding 'Old China' is not just a nice-to-have but a necessity. It is the market, and those who ignore it do so at their own peril.
