Core Viewpoint - The article discusses various arbitrage strategies available for Exchange-Traded Funds (ETFs), emphasizing the importance of selecting strategies based on individual investment research capabilities and risk tolerance. Group 1: Arbitrage Strategies - There are three popular arbitrage strategies for ETFs: discount arbitrage, intraday swing arbitrage, and event arbitrage [1] - Discount arbitrage involves exploiting the price difference between the primary market (creation/redemption) and the secondary market (trading price) of ETFs [2] - Premium arbitrage occurs when the secondary market price exceeds the net asset value, allowing investors to buy underlying stocks and create ETF shares for profit [4] Group 2: Discount and Premium Calculation - The discount rate is calculated as (real-time reference net value - market price) / real-time reference net value, and arbitrage is feasible when the discount rate exceeds transaction costs [3] - The premium rate is calculated as (market price - real-time reference net value) / real-time reference net value, and arbitrage is feasible when the premium rate exceeds transaction costs [4] Group 3: Operational Considerations - Executing discount and premium arbitrage requires a high level of programmatic trading capabilities to quickly capture price discrepancies and perform large-scale creation/redemption operations [5] - Investors should select ETFs with more pronounced premium/discount effects and smaller tracking errors for better arbitrage opportunities [5] - The process involves comparing secondary market prices with real-time reference net values, calculating expected arbitrage returns, and executing trades accordingly [6]

Core Viewpoint - The recent ETF investment frenzy labeled as "arbitrage" is cooling down, with significant losses for investors who participated in the "信创" ETF arbitrage movement as the ETFs have collectively dropped below their pre-suspension levels [1][4] Group 1: ETF Investment Dynamics - The announcement of a merger between 海光信息 and 中科曙光 led to a surge in interest for the "信创" ETFs, which are linked to these stocks, as investors anticipated potential gains upon their resumption of trading [2][3] - From May 26 to June 9, the "信创" ETFs saw a massive inflow of funds totaling 71.7 billion yuan, with some ETFs experiencing over 20-fold increases in their share volumes [3][4] - Following the resumption of trading on June 10, the "信创" ETFs were collectively sold off, resulting in declines ranging from 2.5% to 3.8% [3][4] Group 2: Risks and Limitations of ETF Arbitrage - Investors attempting to leverage the "信创" ETFs for gains faced multiple risks, including the dilution of returns due to increased ETF scale and changes in redemption rules that may disadvantage original holders [5][9] - The significant increase in ETF scale during the suspension of the stocks led to a dilution of the stocks' weight in the ETFs, reducing their potential contribution to returns upon resumption [7][11] - The shift in redemption rules from "allowed" to "mandatory" cash substitutes for the suspended stocks limited investors' ability to execute arbitrage strategies effectively [8][10] Group 3: Controversy Over Fund Management Practices - A debate has emerged regarding whether the redemption rules implemented by certain fund managers have harmed the interests of original ETF holders, as the influx of new capital diluted their potential returns [9][11] - Fund managers, such as 国泰基金, have faced scrutiny for their decisions to adjust redemption limits and rules, which some argue may have encouraged arbitrage and further diluted original holders' interests [10][11] - The outcome of this ETF arbitrage episode raises questions about how fund managers can better balance the interests of new and existing investors in future scenarios [11]

Group 3: Operational Challenges in ETF Arbitrage - The operational challenges for ETF arbitrage were highlighted, as the presence of suspended stocks complicates the redemption process, potentially leading to cash instead of stock for those stocks marked as "must" in the cash alternative section [9][10]. - The ETFs' performance is also influenced by the volatility of other constituent stocks, which can affect the overall ETF price, especially in premium situations where the price may already reflect some arbitrage potential [10]. Group 4: Future Outlook - Despite the recent pullback in the 信创 sector, several institutions remain optimistic, citing the ongoing AI Agent trend and the acceleration of commercialization as drivers for a potential annual tech rally [11]. - The 信创 industry is expected to continue evolving towards "technology complementary integration" and "ecosystem construction," indicating a robust outlook for the sector [11].

Group 3: ETF Dynamics - The significant drop in ETF prices is attributed to arbitrage activities, where funds that anticipated the rise in individual stocks sold off ETF shares to lock in profits after the stocks' price increases [4][10]. - During the suspension period before the merger announcement, the assets under management of related ETFs surged, with some increasing nearly sevenfold, which diluted the impact of the individual stocks' price increases on the ETF's net asset value [4][8].
