Group 1 - The article introduces various common options strategies and highlights the backtesting results of a covered call strategy in the A-share market, showing significant excess returns during downtrends and sideways phases compared to holding ETFs [1] - The Shanghai Stock Exchange, Shenzhen Stock Exchange, and China Financial Futures Exchange provide various options based on broad indices and ETFs, with the trading volume of options gradually increasing, particularly the daily trading volume of the CSI 1000 options reaching around 1.9 billion [1] - Common options strategies can be categorized into single-leg strategies, spread strategies, hedging protection strategies, volatility strategies, and exotic strategies, with exotic strategies like Snowball and Vanilla gaining popularity in recent years, although options-related strategies are still relatively rare in domestic public funds [1] Group 2 - In overseas markets, covered call and hedging products are developing rapidly, with examples like RYLD and QYLD, which effectively reduce the net asset value volatility of their underlying indices [2] - The Russell 2000 index has been in a wide-ranging fluctuation since 2021, and RYLD's net asset value volatility is significantly lower than that of the index, providing a better holding experience for investors [2] - However, in trending upward markets, while covered call products can reduce volatility, their returns often lag behind the underlying index, as evidenced by QYLD's performance being significantly lower than that of the Nasdaq 100 index since 2021 [2] Group 3 - The backtesting results of the covered call strategy using existing 300ETF and 500ETF options indicate that the strategy significantly smooths the net asset value trajectory, with most performance metrics outperforming pure holding of the 300ETF, reducing the maximum drawdown from 42% to 22% [3] - During downtrends and sideways phases in the CSI 300, the covered call strategy clearly outperforms pure holding of ETFs, with better results observed in years with significant declines (2022, 2023) when using in-the-money options [3] - In years with smaller declines (2021), both in-the-money and out-of-the-money options can enhance returns, while in years with smaller gains (2025 to present), higher out-of-the-money options can boost returns; however, in years with larger gains (2020 and 2024), the covered call strategy underperforms direct ETF holdings [3]
