Investors Flock to Chinese Equity Derivatives as Crowded AI Bets Spur Diversification Shift

Investors are increasingly turning to Chinese equity derivatives as a way to diversify away from the most crowded artificial intelligence trades in Asia, according to trading desks and strategists at major banks.

Barclays, UBS Group and Bank of America are among the firms seeing a surge in client interest for bullish options and swap contracts tied to China’s CSI indexes in recent weeks, Bloomberg reported. The activity reflects a broader search for alternative sources of equity returns as valuations in some of the market’s most popular global themes come under scrutiny.

UBS highlighted the CSI 500 index as an alternative AI bet for investors looking to diversify their exposure, according to a recent report cited by Bloomberg. The bank’s sales and trading desk noted on Aug. 30 that the largest weekly derivatives flow in Asia came from bullish bets on China’s CSI indexes, with multiple sizable requests for long swaps concentrated in the CSI 300 and CSI 500, along with upside option structures.

“We’ve seen growing investor interest in China A-share upside strategies in recent months,” Kaanhari Singh, Barclays’ head of Asia Pacific equity-flow derivatives sales, said in the report. “Part of this reflects investors looking to diversify sources of equity returns as questions emerge around valuations and return expectations in some of the market’s most-crowded themes globally.”

The push into China onshore stocks is driven by several factors, including ongoing capital-market reforms that support a gradual bull market, advances in self-reliant technology and an improving earnings outlook across hardware sectors, according to strategists at BNP Paribas and Bank of America cited by Bloomberg.

The growing weight of technology in Chinese indexes is also helping to attract investors as the government pushes for the industry’s self-reliance, BNP Paribas noted. Tech has become the highest-weighted sector in the CSI 300 Index, and its share has increased in the mid- and small-cap CSI 500 and CSI 1000 gauges.

“China onshore offers a very different exposure to AI due to nation’s own ecosystem,” said Jason Lui, BNP Paribas’ head of Asia-Pacific equity and derivatives strategy. “So there is a natural diversification compared to the global AI trade. Now, having that more well-contained volatility profile also encourages more medium-term asset allocation from both domestic and international institutional investors.”

Even so, traders remain cautious about China’s economic outlook and the extent of government support. The CSI 1000 Index, which rose after posting its worst monthly loss since 2016 in July, is still 16% below its May high, Bloomberg data showed. Implied volatility – a measure of options prices – has slumped back toward its one-year average, making derivative bets more attractive on a relative basis.

“It’s an ideal trade now because people are a bit on edge,” said Lars Naeckter, head of Asia Pacific equity-derivatives research at Bank of America, who recommends call spreads on the CSI 1000. “Rather than piling into cash equities or futures, options make sense, especially when pricing is in your favour. At some point, a catalyst will emerge, and it is often cheaper to be tactically proactive ahead of a move rather than reactive.”

At Barclays, the desk is seeing rising client interest in call spreads on onshore indexes, with many positioning for a gradual climb rather than a sharp rally. Outperformance trades linked to the CSI 300 and CSI 500 indexes are also compelling versus recent history, according to Singh.

In the US, a trader on Sept. 4 bought a huge block of bullish calls on the KraneShares CSI China Internet Fund, betting it would return to prices seen earlier in 2026, Bloomberg reported.

The shift toward Chinese stocks comes as investors reassess the risk-return profile of the global AI trade, which has been heavily concentrated in South Korean and Japanese stocks. The derivative flows into China’s CSI indexes offer a way to gain exposure to the technology theme through a distinct domestic ecosystem, at a time when options pricing is favorable.
