Core Insights - The article discusses the integration of a volatility timing straddle option strategy into common stock-bond asset allocation portfolios, resulting in a reduction of maximum drawdown by approximately 5% and an increase in the Calmar ratio by over 0.1 [1][2] Group 1: Volatility Timing Strategy - The article highlights that the performance of long-term option buying strategies, such as directly purchasing put protection options, has been subpar in both domestic and international markets [1] - It emphasizes that while the A-share market lacks direct trading tools based on volatility indices, investors can still construct equivalent volatility strategies using existing ETF options [1][2] - The article notes that single-leg strategies involving 300ETF options exhibit high volatility and drawdown, making them unsuitable for risk-averse allocation funds [1] Group 2: Straddle Option Strategy - The straddle strategy is found to have lower volatility and drawdown compared to single-leg strategies, with annualized volatility generally below 0.1 [2] - Selling straddle options can provide relatively stable excess returns, while buying options does not yield long-term excess returns due to high premiums and infrequent large market movements [2] - The article suggests that extreme volatility often follows periods of historically low volatility, indicating a potential "coiling" effect before significant market movements [2] Group 3: Implementation and Results - The article proposes a timing mechanism where buying straddle options is preferred when volatility drops to historically low levels (thresholds of 5%, 10%, 15%) to mitigate the risk of sudden volatility spikes [2] - The implementation of the volatility timing straddle option strategy into a common stock-bond asset allocation portfolio, allocating 10% of stock weight to the option strategy, results in a reduction of maximum drawdown from 21.4% to 13.5% and an increase in annualized return from 3.5% to 5.8% [2]

Core Viewpoint - The bond market is likely transitioning from a completed "five-wave" pattern to an adjustment wave, with historical data suggesting that the decline from the peak could be around 30%-35% of the previous gains [1][4]. Summary by Sections Wave Theory - Wave theory, proposed by Ralph Nelson Elliott, suggests that market price fluctuations follow a cyclical pattern similar to natural tides, exhibiting identifiable patterns and cycles [2]. Historical Review of Bond Market Waves - From early 2023 to early 2025, the bond market has completed a "five-wave" sequence: 1. **First Wave (March 2023 - August 2023)**: The end of redemption pressures led to a strong bond market amid weak economic expectations and asset scarcity. 2. **Second Wave (August 2023 - October 2023)**: Post-unexpected interest rate cuts, profit-taking sentiments emerged alongside local government bond supply pressures, causing market fluctuations. 3. **Third Wave (October 2023 - September 2024)**: Weak risk assets and expectations of lower interest rates fueled speculative sentiment in the bond market, despite central bank warnings about interest rate risks. 4. **Fourth Wave (Late September 2024 - October 2024)**: Multiple policies were implemented, leading to a rapid stock market rise, which pressured bond market sentiment. 5. **Fifth Wave (November 2024 - January 2025)**: Expectations of interest rate cuts and weak economic conditions drove interest rates down again [3]. Adjustment Wave Analysis - The bond market's adjustment wave began in February-March 2025, characterized by tightening liquidity and weakening institutional sentiment. Although there was a slight recovery, it did not surpass previous highs. The current bond market has formed an "M-top" pattern, with historical comparisons indicating that the first and second declines after reaching the peak typically reflect a drop of 30%-35% of prior gains [4].
