Core Viewpoint - The article discusses the contrasting performances of A-shares and Hong Kong stocks, highlighting that A-shares have outperformed since July, while Hong Kong stocks have lagged behind due to fundamental issues, liquidity constraints, and low valuation premiums [2][6][26]. Market Performance Overview - The market performance in 2023 can be divided into three phases: 1. January to March: Hong Kong stocks outperformed, driven by AI and technology sectors 2. April to June: U.S. stocks led the market, with Chinese stocks recovering but not reaching previous highs 3. July to present: A-shares surged due to liquidity-driven tech trends, while Hong Kong and U.S. stocks remained volatile at high levels [2][6]. Reasons for Hong Kong's Underperformance - Hong Kong stocks have underperformed due to three main factors: 1. **Fundamentals**: Earnings growth expectations for Hong Kong stocks have been downgraded, contrasting with improvements in A-shares 2. **Liquidity**: The rise in Hibor rates indicates tightening liquidity in Hong Kong 3. **Valuation**: The AH premium has decreased, reducing the attractiveness of Hong Kong stocks [6][18][24]. Earnings Growth Analysis - Hong Kong's net profit growth for the first half of 2023 was 4.2%, while A-shares saw a lower growth of 2.8%. However, A-shares are expected to improve in 2024, while Hong Kong's earnings growth is projected to decline [7][11]. - The earnings per share (EPS) growth forecast for the Hang Seng Index for 2025 has been downgraded to -2.7%, indicating potential negative growth in the second half of the year [11][12]. Liquidity Conditions - Since mid-August, liquidity in Hong Kong has tightened significantly, with Hibor rates spiking to 4.6% before stabilizing around 2.5%. This contrasts with the active liquidity environment in A-shares, where trading volumes have increased significantly [18][23]. Valuation Insights - The AH premium has fallen below 125%, reducing the appeal of Hong Kong stocks for mainland investors due to tax implications. This has contributed to the recent underperformance of Hong Kong stocks [24][26]. Investment Strategy Recommendations - Investors are advised to focus on A-shares if they believe in the continuation of liquidity-driven trends, while those concerned about sustainability may find more stable opportunities in Hong Kong stocks, particularly in sectors with favorable structural dynamics [29][38]. - Key sectors to watch in Hong Kong include pharmaceuticals, technology hardware, non-bank financials, and consumer electronics, which are expected to show higher earnings growth and stability [38][40]. Conclusion on Market Dynamics - The article concludes that while A-shares are currently leading, there is potential for Hong Kong stocks to benefit from structural improvements, especially if the liquidity environment changes. However, the overall market dynamics suggest that structural opportunities will remain more significant than index performance [26][38].
