Group 2: Impact on A-Share Valuation - The current A-H share premium index is at a historical low, with some leading companies' H shares trading at a premium, indicating potential for A-share valuation recovery through arbitrage and value investment mechanisms [2]. - The valuation logic for growth stocks is shifting towards "technical barriers," with the Hong Kong market placing greater emphasis on R&D investment and technological advantages, promoting a transition in the A-share market from valuation-driven to growth-driven [2]. Group 3: Effects on the Hong Kong Market - The listing surge is reshaping liquidity in the Hong Kong market, with southbound capital becoming a dominant force and a rise in growth-oriented investment styles [2]. - Southbound capital inflows and trading proportions have reached historical highs, indicating a shift in market structure from a focus on high-dividend sectors to technology and consumer-driven sectors [2].
