中国商品期权卖权策略优化思路

1. Report Industry Investment Rating No information regarding the report industry investment rating is provided in the content. 2. Report's Core View The report focuses on the optimization of short strategies for China commodity options, analyzing the performance of different option - selling strategies, exploring directional and timing optimizations, and examining the impact of volatility environments on these strategies. It aims to find better investment opportunities and improve the win - rate of option - selling strategies through various optimization methods [7][12][45]. 3. Summary by Relevant Catalogs 3.1 Backtesting of Short Strategies - Performance of Short Put Options: In different gold price scenarios (rally, decline, and range - bounded move), the short put option can earn normal returns in rallies and range - bounded moves but may experience significant drawdowns in declines. In the past year, long - term holding of short put options on gold has shown good results, but protection against sharp declines is needed [7]. - Directional Optimization of Short Put Options: By using moving - average (MA) for directional timing (opening positions when the short MA crosses above the long MA and closing otherwise), the strategy has achieved better results in the past year, with a 50% increase in annualized return compared to standalone puts and about a 2% reduction in drawdown [12]. - Problems with Short Call Options: In the first half of 2025, the continuous and sharp rise in gold prices led to significant drawdowns in short call option strategies. Backtesting results from 2020.1 - 2025.5 show an annualized return of - 11.87% and a maximum drawdown of - 67.62% [19]. - Directional Timing Optimization of Short Call Options: When the 10 - day moving average crosses above the 20 - day moving average, closing short option positions can effectively avoid large drawdowns, reducing drawdowns by about 70%. After hedging, the annualized return of AU improved from - 11.87% to - 0.81%, and the maximum drawdown decreased from - 67.62% to - 20.93% [24]. - Impact of Volatility on Short Straddle Strategy: The short straddle strategy can earn income in range - bounded markets but incurs losses in rallies and declines. It has good long - term returns but faces recent drawdowns due to higher volatility [31]. - Timing Optimization of Short Straddle Strategy: The short straddle strategy with price - movement timing optimization has an annualized return of 6.05%, a maximum drawdown of - 9.97%, a win - rate of 60.21%, and a trade frequency of 1051 times, which is better than the non - optimized short straddle strategy [36]. 3.2 Volatility Environment Analysis - Implied Volatility of Commodity Options - Outlook: The implied volatility of commodity options tends to spike rapidly and decline slowly. This is due to market asymmetry, where sellers suppress IV in range - bounded markets, and when events occur, IV surges due to increased hedging and speculative demand, and then gradually declines as the market stabilizes [45]. - Implied Volatility of Commodity Options - Example of Copper: The short straddle strategy for copper options can continuously obtain time value at the Theta end and has a better holding experience as IV downtrends usually last longer. However, it needs to avoid the "double - kill" of Vega and Gamma caused by short - term IV spikes. The report aims to improve the win - rate by filtering short - straddle environments through volatility statistical features [50]. - Review of Short Straddle Environments in Commodity Options: Using a 20 - day rolling window to group implied volatility into 10 levels, the weekly performance of short straddle strategies for most commodities shows a "U - shape", performing better at low or high volatility levels and weaker at mid - range volatility. The preferred put - selling ranges are the 20 - day low (below 0.2 percentile) or 20 - day high (above 0.8 percentile), and short - straddling in these ranges for selected 10 commodities can optimize win - rates and payoff ratios [63][68]. - Example of Lithium Carbonate Options: When the implied volatility of lithium carbonate options retreats from highs and the option market activity is weak, it is suitable to deploy short option strategies [73].
