Core Viewpoint - The article discusses the concept of "offshore fund arbitrage," emphasizing that it is not a speculative tactic but a strategy to profit from price differences or time windows in fund trading rules. Group 1: Offshore Fund Arbitrage - Offshore fund arbitrage is based on the principle of "buy low, sell high" or "earning time differences through rules," but it is important to note that there is no risk-free arbitrage [1]. - All operations must account for costs and control risks, ensuring that profits exceed costs before proceeding [1]. Group 2: LOF Fund Arbitrage - The easiest arbitrage method for individual investors involves LOF funds (Listed Open-Ended Funds), which can be traded both off-market at net value and on-market at market price [3]. - When the on-market trading price exceeds the off-market net value, a "premium arbitrage" opportunity arises, allowing investors to buy low off-market and sell high on-market for profit [3]. Group 3: Practical Steps for LOF Arbitrage - Step 1: Select targets by using tools like Jisilu to find LOF funds with a premium rate of at least 3% and a daily trading volume over 10 million, avoiding those with suspended subscriptions [4]. - Step 2: Purchase the selected LOF A shares through platforms like Alipay or Tian Tian Fund, and after confirmation (usually T+2 days), initiate a "cross-system transfer" to a brokerage [4]. - Step 3: After the transfer application is submitted, the shares will arrive in the securities account on T+2 days, and investors can sell them like stocks [5]. Group 4: Example of LOF Arbitrage - An example is provided where a certain S&P 500 LOF has a premium rate of 25.9%, with an off-market purchase net value of 1 yuan and an on-market trading price of 1.259 yuan, leading to a potential profit of approximately 0.2 yuan per 1 yuan invested after deducting fees [6]. Group 5: ETF Arbitrage - ETF arbitrage was traditionally exclusive to institutions, but individual investors can participate through offshore ETF linked funds, which invest primarily in corresponding ETFs [7]. - The core logic involves taking advantage of the lag in net value response of linked funds when ETFs are at a premium or discount [7]. Group 6: Directions for ETF Arbitrage - Premium arbitrage occurs when the on-market price of an ETF exceeds its net value, allowing for off-market purchases of linked funds, followed by redemption for profit once the net value rises [8]. - Discount arbitrage happens when the on-market price is lower than the net value, allowing for redemption of linked funds and re-purchase at a lower net value for profit [9]. Group 7: Key Considerations for Arbitrage - It is crucial to calculate costs accurately, ensuring that arbitrage profits cover all fees, as a premium rate below 3% may lead to losses [11]. - Control time risks, as the transfer and confirmation processes require time, during which market fluctuations may erode profit margins [12]. - Confirm liquidity by selecting LOF/ETF targets with high daily trading volumes to avoid difficulties in selling once transferred to the market [13]. - Adhere to rules, ensuring accounts are in the same name and that shares are in whole numbers during transfers to avoid arbitrage failures [14]. - Avoid excessive greed; new investors are advised to start with small amounts to familiarize themselves with the process before scaling up [15].

Core Viewpoint - Cross-border ETF funds, also known as "QDII ETF" funds, are investment funds established domestically that invest in overseas markets, creating arbitrage opportunities due to potential pricing discrepancies between market trading prices and net asset values [1] Group 1: Trading Mechanism of Cross-border ETF Funds - Cross-border ETF funds can be traded on the Shanghai and Shenzhen stock exchanges, allowing for both on-market trading and subscription/redemption operations [1] - The trading mechanism includes T+0 trading, enabling same-day buy and sell transactions without limits on trading frequency [2] - ETF fund shares redeemed require T+2 settlement for the funds to be available [2] Group 2: Necessary Conditions for Arbitrage - Selecting brokers that support RTGS settlement mechanisms is essential, as only a few brokers provide this support [3] - Ensuring low transaction costs is crucial to minimize friction costs, including subscription, redemption fees, and trading commissions [3] - A deep understanding of the trading mechanisms of cross-border ETF funds is necessary, and consulting with securities advisors is recommended [3] Group 3: Instant Arbitrage Strategies and Steps - Instant arbitrage can be categorized into premium arbitrage and discount arbitrage [4] - For premium arbitrage (when market price > IOPV): 1. Subscribe to cross-border ETF by following the daily published subscription list and obtaining ETF shares [5] 2. Sell the ETF shares in the secondary market at the expected market price [5] - For discount arbitrage (when market price < IOPV): 1. Buy ETF shares in the secondary market at the expected market price [5] 2. Redeem the ETF shares to receive a basket of stocks or cash, avoiding the need to sell stocks if cash is redeemed [5]
