Hong Kong Stock Connect Expansion One Month On: Southbound Funds Snap Up Tencent and Alibaba, Bolstering Hang Seng Valuations

The Hong Kong stock Connect target adjustment has been in effect for one month, and the flow of southbound capital has shown clear structural changes. New economy heavyweights such as Tencent and Alibaba have become the core recipients of this round of incremental funds, and their support for the Hang Seng Index's valuation is gradually becoming evident.

Expanded Targets: New Economy Heavyweights See Concentrated Allocation

The latest adjustment to the Stock Connect target list took effect a month ago, bringing several new economy leaders into the fold or adjusting their weights. According to southbound shareholding records disclosed by the Hong Kong Stock Exchange, the southbound shareholding ratios of targets such as Tencent Holdings and Alibaba rose significantly in the first week after the adjustment took effect. Market analysts point out that this expansion is not merely an addition to the list but a further optimization of the Hang Seng Index's constituent structure, allowing mainland investors to participate more directly in the allocation of core assets in the new economy sector.

Looking at the specific pace of capital flows, southbound funds exhibited a clear "snap-up" characteristic in the early stages of the expansion. According to statistics from third-party data providers, in the first ten trading days after the adjustment, the net inflow of southbound funds expanded compared to the average level of the previous month, with a notable increase in the proportion of funds flowing into the information technology sector. As the two largest constituents of the Hang Seng Index, Tencent and Alibaba saw their southbound shareholdings grow at a pace that ranked among the top of all Stock Connect targets.

Valuation Support: Incremental Funds Reshape the Pricing Logic of the Hang Seng

The sustained inflow of southbound capital has had a tangible impact on the valuation system of the Hang Seng Index. Before the expansion, the Hang Seng's price-to-earnings ratio had long been below its historical median, and the valuations of some new economy leaders were even lower than their historical averages. With the concentrated buying by southbound funds, the valuation centers of these targets have shown signs of upward movement. According to Wind data, by the one-month mark of the expansion, the average P/E ratio of Hang Seng Tech Index constituents had risen compared to pre-expansion levels, but overall remained within a reasonable range.

A strategist at a major institution noted in a recent report that the pricing power of southbound funds is strengthening. In the past, the Hong Kong market was primarily dominated by international capital, and valuation fluctuations were heavily influenced by the Federal Reserve's monetary policy. As the share of mainland capital increases, Hong Kong valuations are beginning to reflect more of the risk appetite and liquidity conditions of mainland investors. This shift is particularly evident in targets like Tencent and Alibaba, where the correlation between their stock price movements and net southbound inflows has increased significantly since the expansion.

Capital Structure: Divergent Choices by Institutions and Retail Investors

From a capital structure perspective, this round of southbound buying is not driven by a single force. According to data from the Hong Kong Stock Exchange's Central Clearing and Settlement System, in the month following the expansion, institutional investors accounted for approximately 60% of the funds that bought Tencent and Alibaba through Stock Connect, with the remainder coming from retail investors. Institutional capital tended to build positions quickly in the early stages of the adjustment, while retail investors followed gradually.

Notably, southbound funds have not treated all new economy targets equally. While Tencent and Alibaba saw increased allocations, some small- and mid-cap new economy targets experienced net selling. Analysts believe this reflects that southbound funds are placing greater emphasis on liquidity and fundamental certainty after the expansion, rather than simply chasing the "new economy" label. This divergence helps optimize the efficiency of resource allocation in the Hong Kong market.

Outlook: Room for Incremental Growth and Potential Risks

Looking ahead, the supportive effect of southbound funds on the Hang Seng Index still has room to continue. On one hand, the allocation of mainland public funds, insurance capital, and other long-term funds to Hong Kong stocks remains below policy caps, leaving potential for further increases. On the other hand, as more new economy companies list in Hong Kong, the pool of Stock Connect targets is likely to expand, offering southbound funds more choices.

However, risk factors also exist. If the Federal Reserve maintains higher interest rates for a longer period, global risk appetite could be suppressed, thereby affecting Hong Kong's overall valuations. Additionally, the concentrated inflow of southbound funds could lead to overcrowded trading in some targets, and if market sentiment reverses, the pullback could be amplified. While investors focus on the opportunities brought by incremental funds, they should also be wary of the risk of overextended valuations.

In summary, as the Stock Connect expansion marks its one-month anniversary, the southbound buying spree in new economy leaders like Tencent and Alibaba has provided effective support for the Hang Seng Index's valuation. In the future, as mainland capital's voice in the Hong Kong market grows, this support is likely to spread from individual heavyweights to a broader range of sectors.
