Group 1: Overview of QDII ETF - QDII ETFs are primarily focused on Hong Kong stocks, experiencing rapid growth since 2021, with a significant increase in non-Hong Kong ETFs starting in 2023, reflecting a shift in investor interest towards overseas markets [3][12] - As of November 28, 2025, the cumulative scale of QDII ETFs reached 185.86 billion, indicating a growing trend in overseas investment opportunities [12] - The top 15 QDII ETFs by scale include products like Huaxia Hang Seng Technology ETF and Guotai Junan Nasdaq 100 ETF, with scales of 47.64 billion and 16.90 billion respectively [9][13] Group 2: Mechanism of Premium and Discount Formation - The premium formation mechanism for QDII ETFs relies on cash subscription and redemption, where the return to premium depends on the ability to arbitrage through "subscription + sale" [3][21] - High premiums often arise from disruptions in the arbitrage chain, particularly when subscription limits are imposed due to insufficient QDII quotas [27] - The expected arbitrage returns vary based on market conditions, with overlapping trading hours leading to different calculations of the indicative optimized price value (IOPV) [31][36] Group 3: Evaluation of QDII ETF Premiums - The premium rate is negatively correlated with the cost-effectiveness of QDII ETFs; for instance, when the premium rate exceeds 8%, holding the ETF for a month typically results in significant negative returns [3] - Daily subscription limits and market sentiment are significant factors influencing premium rates, with emotional factors providing long-term explanations for premium levels [3][27] - Some QDII ETFs exhibit additional premiums that cannot be easily explained by market sentiment, indicating potential inefficiencies in pricing [3][27] Group 4: Recent Developments in QDII ETFs - The number of QDII ETFs tracking new indices has been increasing, particularly those focusing on non-Hong Kong indices such as the Dow Jones Industrial Average and the S&P 500 Consumer Select Index [17] - Newly launched QDII ETFs often experience initial premiums, with the Huatai Baichuan South China Arabian ETF showing a first-day premium of 6.31% [17][18] - The overall market enthusiasm for QDII ETFs remains high, as evidenced by the sustained premium levels of newly listed products [17][18]
