Mainland Chinese Investors Pump the Brakes on Hong Kong Stocks as AI Options Flourish Across Markets

Southbound stock inflows decelerate as pure-play AI investment alternatives multiply

Investors from mainland China have significantly reduced their acquisitions of Hong Kong-listed equities during the current year, marking a sharp reversal from the exceptional inflow surge witnessed in 2025, according to analysis from BNP Paribas.

Cross-border purchasing through the Stock Connect mechanism has accumulated approximately US$30 billion through 2026 to date, representing a notable deceleration compared with US$180 billion achieved across the entirety of 2025, the Paris-based financial institution reported. Rather than signaling reduced confidence in Chinese assets, strategists from BNP Paribas indicated at a Wednesday media session that this moderation reflects a fundamental shift in how investors pursue exposure to the sector.

"Investors maintain optimistic sentiment regarding China's artificial intelligence trajectory," stated Jason Lui, who oversees Asia-Pacific equity and derivative strategy operations. He elaborated that "the distinguishing factor this year is that investors possess considerably more avenues through which to execute their investment thesis."

From Concentrated Bets to Diversified Exposure

The extraordinary momentum experienced throughout 2025 was predominantly fueled by the unexpected emergence and rapid ascent of AI startup DeepSeek, an event that caught market participants off guard and subsequently triggered concentrated purchasing of Hong Kong-domiciled technology corporations. The current year lacks a comparable catalyst of equivalent magnitude, while the preceding six to nine months have witnessed a substantial wave of new public listings that have broadened the spectrum of pure-play artificial intelligence investment vehicles available on both mainland and Hong Kong trading platforms.

This expanded selection has prompted a measurable repositioning of capital, with investors gravitating toward targeted positions in specific enterprises rather than maintaining broad index-level exposure. Consequently, the historical reliance on Hong Kong technology stocks functioning as surrogate instruments for capturing AI-related growth has diminished in significance.

Kenny Tang Sing-hing, chairman of the Hong Kong Institute of Financial Analysts and Professional Commentators, attributed the slowdown partially to the elevated baseline established by the prior year's exceptional performance, noting that year-over-year comparisons naturally reflect this elevated foundation.
