In recent times, the landscape of investing has seen a stark divergence between the performance of stocks on the mainland Chinese markets (A-shares) and those listed in Hong Kong (H-shares). The scenario has raised eyebrows among financial analysts and investors alike, particularly given the structural challenges and taxation issues that have plagued the Hong Kong stock market. Despite the allure of high dividend stocks, mainland investors find themselves in a quandary due to a lack of favorable economic conditions and the burdensome tax implications associated with the Hong Kong stock market.

Starting in January 2024, both A-shares and H-shares witnessed dismal performances. For instance, on January 17, the Shanghai Composite Index fell a staggering 2.1%, while the Hang Seng Index experienced a more severe plunge of 3.7%. This downturn can be interpreted not just as an economic indicator but also as a reflection of rising investor anxiety amid a broad range of macroeconomic concerns. A shift towards lower valuations has been noted in the A-share sector, particularly among high-dividend stocks, with the Shenzhen Component Index displaying significant strength amidst the overall downtrend, revealing an 8% drop from its end-of-year closing value. Comparatively, the Shanghai index exhibited a more modest decline of 5%.

Meanwhile, the Hang Seng Index's trajectory has not been as favorable. The backdrop of a 10% decrease underscores the challenges faced by the Hong Kong listings, whereby even state-owned enterprises characterized by low valuations and high dividends saw an 11% slump. The severity of this underperformance indicates a notable divergence in investor sentiment between the mainland and Hong Kong markets, marking the symptoms of a fractured financial ecosystem.

The prevailing adverse conditions have adversely impacted the valuations of numerous quality companies, contributing to a negative wealth effect and undermining overall societal confidence. Clearly, there is a pressing need for regulatory interventions aimed at addressing market pain points and initiating reforms that could catalyze recovery. With high dividend strategies fulfilling a critical demand for safer investments, the ramifications of declining market indices cannot be understated.

Notably, by December 2023, the Consumer Price Index (CPI) indicated a year-on-year decrease of 0.3%, revealing early signs of deflation. During this time, market interest rates began a downward trend, leading to the ten-year treasury yield plummeting to historic lows, teasing a figure around 2.5%. In an environment where secure, higher-yielding assets remain elusive, many investors have funneled their resources into conventional sectors such as coal and banking that offer reliable dividends. This transition is one of the key elements explaining why the Shanghai index outperformed the Shenzhen component index at the start of the year.

Reflecting upon this transition, one notable case is China Shenhua Energy's A-shares, which surged from 31.35 yuan at the end of 2023 to 34.14 yuan by mid-January—a notable rise of 8.9%. Even after this substantial increase, China Shenhua’s dividend yield maintains an attractive 7.5%. However, this upward trend is not mirrored in the Hong Kong territories, where dividend stocks are suffering from an entirely different set of issues. For example, the stock of the Industrial and Commercial Bank of China displayed a contrasting narrative. The A-shares increased from 4.68 yuan to 4.84 yuan over the same timeframe, supported by a yield of over 6.2%. In stark contrast, its H-share counterpart decreased from 3.82 HKD to 3.55 HKD, presenting a substantial discount to its A-share listing.

The apparent inability for these undervalued, high-dividend stocks to thrive in Hong Kong raises critical questions about the future efficacy of the stock-connect model. Since 2022, numerous factors have compounded investor hesitance regarding investments, including worsening Sino-U.S. relations and rising interest rates in the American economy. Consequently, Western investors have fled from Chinese equities, a trend corroborated by reports from well-regarded financial entities. As of the third quarter of 2023, approximately 127 billion USD had exited from Chinese stocks due to overseas funds, adding more pressure to an already beleaguered marketplace.

Nevertheless, the outflow of international capital has carved out opportunities for domestic investors. Local mainland and Hong Kong-based funds have stepped in significantly to cushion the market from the brunt of foreign capital withdrawal. This influx can be quantitated, with southbound capital numbered at over 700 billion HKD since 2022. As of November 2023, daily trading volume attributed to southbound purchases constituted around 30% of total turnover in Hong Kong's stock markets.

However, despite a rise in domestic holdings and the proportion of stocks held through the Hong Kong Stock Connect, mainland investors are still confronting formidable challenges. The burden of dividend taxes has emerged as a predominant barrier discouraging many from embracing high-yield assets. The current structure grants mainland individual investors a tax burden ranging well beyond local norms when participating via the Stock Connect initiative. Specifically, corporate dividends received from red-chip enterprises incur two taxation events—30% withheld tax by corporations followed by an additional personal income tax of 20%, amounting effectively to a staggering total of 28% tax on dividends.

In stark contrast, local investors in Hong Kong do not confront dividend taxes on local listings, contributing to a disparity that has left many Chinese investors in a lurch. Despite the appeal of dividend-rich assets such as China National Offshore Oil Corporation, valued at just 13.18 HKD with a dividend yield hitting 10.2%, the A-share counterpart lists much higher at 20.66 yuan—a discrepancy of nearly 41.4% between the two markets. This lack of tax disparity adds to the conundrum for investors seeking stability and security through dividends, which further complicates the investment landscape.

In the wake of these trends, it is imperative for the Chinese financial authorities to take note. For individuals investing via the Stock Connect, the scenario is disheartening: they neither benefit from tax exemptions promoted by existing policies nor gain from preferential conditions extended towards individual investors in local markets. Consequently, taxpayers are facing dividend taxation exposure considerably higher than their Hong Kong or mainland A-share counterparts.

Urgent measures need to be advocated between the Central Clearing and Settlement System and the Central Securities Depository. Enhancing operational efficiency in dividend taxation and collectively striving toward unified investor records would decrease instances of double taxation on dividends, fostering a more straightforward investment horizon.

Moreover, the authorities must extend preferential taxation terms similar to those enjoyed by A-share investors to their counterparts within the Stock Connect framework. Bridging this policy gap could provide fundamental support in recalibrating dividend flows back into the Hong Kong markets, solidifying its role and status within the international financial landscape, particularly as it seeks to recover from earlier setbacks.

As we move forward, understanding the intricate dynamics of taxation and market sentiment will be paramount. With fluctuations impacting market stability, a focus on reformation will not only benefit individual investors but also enhance the collective health of the financial ecosystem, vital for the sustained success of both the Chinese and Hong Kong markets.
