Asian Investors Grow Optimistic on China Stocks, Equity Derivatives Become a New Choice

Chinese corporate profits grew 25.7% year-on-year in the second quarter of 2026, the fastest pace in nearly five years. However, China's stock performance throughout the same quarter actually weakened, with the CSI 300 index falling about 9% and the Star 50 technology index plunging 29%. 

This irony is what prompted Asian investors to seek new ways to bet on China's economy, and their choice fell on equity derivative instruments rather than buying stocks directly.

According to a Bloomberg report published in early September 2026, major banks such as Barclays, UBS, Bank of America, and BNP Paribas recorded a surge in client interest in bullish options and swaps tracking CSI indices — especially CSI 300, CSI 500, and CSI 1000. 

This trend aligns with a shift in Asian investor sentiment, which is growing weary of the AI theme in South Korea and Japan, two markets considered overcrowded by a single investment theme.

Key Takeaways

• Trading desks at Barclays, UBS, Bank of America, and BNP Paribas noted a surge in investor interest in bullish derivatives on China's CSI indices as an alternative AI exposure outside South Korea and Japan.
• UBS explicitly recommends CSI 500 as a way to diversify AI trade risk, while implied volatility of CSI 300 options has fallen close to the one-year average.
• Despite Chinese corporate profits growing at the fastest pace in five years (25.7% YoY), the performance of CSI 300 and Star 50 stocks weakened, reflecting investor skepticism about the sustainability of returns from China's AI investments.

Why Are Asian Investors Turning to China Stock Derivatives?

The shift is quite clear: global funds that were previously concentrated on AI stocks in South Korea and Japan are now starting to seek diversification through the Chinese market. 

Lars Naeckter, Head of Asia Pacific Equity-Derivatives Research at Bank of America, described the current conditions as "ideal" for derivative trading because investors remain cautious about market direction. He recommends a call spread strategy on CSI 1000, arguing that options are more sensible than buying stocks or futures directly when prices are favourable.

Kaanhari Singh, Head of Asia Pacific Equity-Flow Derivatives Sales at Barclays, reported similar findings. According to him, client interest in call spread strategies on China's onshore indices has been rising steadily over the past few months, with most investors positioning for gradual gains rather than a sharp rally in a short time.

UBS data even shows that in the week ending August 30, 2026, the largest derivative flows in Asia came from bullish bets on China's CSI indices — dominated by demand for long swaps on CSI 300 and CSI 500.

One driving factor: implied volatility of CSI 300 options has fallen close to the one-year average, making entry costs via options much cheaper. UBS even published a special report titled "CSI 500: A Better Way to Diversify AI Trade Risk," which explicitly positions that index as an alternative AI bet for global investors. 

Jason Lui, Head of Asia-Pacific Equity and Derivatives Strategy at BNP Paribas, added that China's stock market offers exposure that is fundamentally different from the global AI trend, because the country has its own technology ecosystem, thus providing natural diversification and a more controlled volatility profile for institutional investors.

Just as stock investors are starting to seek diversification through derivative instruments, diversifying digital asset portfolios could also be a relevant strategy in the face of market uncertainty. One initial step is to register on an OJK-licensed crypto asset trading platform such as Bittime.

Data Behind the Optimism: Profits Rise, Stocks Fall

The 25.7% profit growth in the second quarter of 2026 was actually driven significantly by AI-related companies. According to UBS Securities' breakdown, earnings of issuers on the ChiNext board rose 42%, while those on the STAR board surged 370% — far above the main market average. 

However, stock price performance did not reflect that earnings surge: CSI 300 fell about 9% and the Star 50 technology index actually collapsed 29% over the same quarter.

This divergence shows that investors are now more sceptical about whether Chinese companies' massive spending on AI infrastructure will actually generate commensurate returns, rather than just short-term euphoria.

The still-depressed property sector also weighed on overall market sentiment — China Vanke's losses widened, Kweichow Moutai's profits declined due to weakening demand, and Muyuan Foods even recorded a loss. 

This combination is why the Chinese market is said to be experiencing a "two-speed earnings recovery": some sectors soar thanks to AI and commodities themes, while others still grapple with weak domestic consumption.

Global Funds Also Rotate: From Wall Street to China's Market

This rotation trend is not just about index derivatives. Emmanuel Sharef, manager of PIMCO's flagship 60/40 Balanced Income and Growth Fund, revealed that they have reduced exposure to the "Magnificent Seven" — the seven US tech giants — citing that these companies' debt burdens have also swelled due to massive AI spending, while their profit outlook has become less clear.

Sharef believes that the next winners of the AI boom will not come from the already overcrowded US tech giants, but from the physical supply chains supporting data centre construction: Asian equipment suppliers, Chinese financial stocks, raw materials, and even the healthcare sector. 

One piece of evidence is the MSCI China Materials Index, which rose about 7.1% over the past month, driven by rising gold and copper prices — turning a sector that was a laggard this year into one of the market leaders. 

In its portfolio allocation in the Chinese market, PIMCO places its largest overweight on the financial sector, which it considers to have relatively low volatility, along with a bullish view on commodities and rare earth metals that are crucial for the technology industry.

Conclusion

The rotation of Asian investors into China stock derivatives shows a new way to invest in the AI theme without adding exposure to the already overcrowded stocks of South Korea and Japan. 

However, this optimism remains wrapped in caution — evident from the preference for using options rather than buying stocks directly, and the divergence between strong corporate profit growth and weakening index performance. 

For global investors, China offers genuine diversification from the global AI trend, but the sustainability of this optimism still depends on whether the massive spending in the technology sector truly yields commensurate results.

FAQ

What are China equity derivatives (CSI derivatives)? 

China equity derivatives are investment instruments such as options and swaps whose value tracks the movement of Chinese stock indices, such as CSI 300, CSI 500, and CSI 1000, without investors having to buy the stocks directly.

Why do investors consider South Korean and Japanese AI stocks overcrowded? 

Because global funds have become heavily concentrated on the AI theme in those two markets, their valuations are considered expensive and potential returns are increasingly limited compared to other markets.

What is CSI 500 and why is it called an AI bet alternative? 

CSI 500 is a mid-cap Chinese stock index whose technology sector weight continues to increase, so UBS considers it a way to diversify AI exposure that differs from the global AI trend.

Does rising Chinese corporate profits mean China stocks will definitely rise? 

Not necessarily. Second‑quarter 2026 data shows profits grew 25.7% but the CSI 300 and Star 50 indices actually weakened, as investors still question the sustainability of returns from massive spending in the AI sector.
