Report Summary Core View - The report provides a daily update on volatility data including implied volatility indices, historical volatility, and their spread trends for various financial and commodity options as of September 30, 2025. It also presents the percentile rankings of implied volatility and volatility spread [2]. Details from Different Sections Volatility Index and Spread - Financial option implied volatility indices show the 30 - day implied volatility (IV) trend as of the previous trading day. Commodity option implied volatility indices are calculated by weighting the IV of the two - strike options around the at - the - money option of the main contract, reflecting the IV trend of the main contract. The difference between the IV index and historical volatility (HV) indicates the relative level of IV to HV [2]. Implied Volatility and Historical Volatility Graph - Graphs display the IV, HV, and IV - HV spread for multiple options including 300 Index, 50ETF, 1000 Index, 500ETF, and various commodity options such as silver, gold, soybean meal, corn, etc. [3]. Implied Volatility and Volatility Spread Percentile Rankings - Implied volatility percentile represents the current IV level of a variety in history. A high percentile means the current IV is high, while a low percentile means it is low. The volatility spread is the difference between the implied volatility index and historical volatility. The report shows the percentile rankings of implied volatility and historical volatility for different options like 50ETF, 300 Index, PTA, etc. [4][5]

Group 1: Explanation of Volatility Metrics - Financial option implied volatility index reflects the 30 - day implied volatility (IV) trend as of the previous trading day. Commodity option implied volatility index is obtained by weighting the IV of the upper and lower two - strike options of the at - the - money option of the main contract month, showing the IV change trend of the main contract [2] - The difference between the IV index and historical volatility (HV) indicates the relative level of IV to HV. A larger difference means IV is relatively higher than HV, and a smaller difference means IV is relatively lower [2] Group 2: Volatility Data Visualization - There are charts showing the IV, HV, and IV - HV differences of various financial and commodity options, including 300 - stock index, 50ETF, 1000 - stock index, 500ETF, and many commodity options like silver, gold, soybean meal, etc [3] Group 3: Implied Volatility and Historical Volatility Quantiles - Implied volatility quantiles represent the current IV level of a variety in history. High quantiles mean the current IV is high, and low quantiles mean it is low. The data shows the implied and historical volatility quantiles of different options such as 50ETF, PTA, 300 - stock index, etc [4][5]

Group 1: Common Option Structures - The three common option structures—Snowball, Phoenix, and Fixed Coupon Notes (FCN)—are essentially barrier options, with specific characteristics regarding cash flow and risk exposure [2][3]. - The classic Snowball structure allows for cash flow only at maturity or upon knock-out, while the Phoenix structure enables monthly cash flow as long as the price is above the knock-in line [2]. - FCN provides fixed coupon payments regardless of price movements during the holding period, making it attractive for conservative investors due to a significantly lower probability of knock-in [2]. Group 2: Profit and Loss Scenarios - In scenarios without knock-in, all three structures yield similar returns, with higher coupon structures being more favorable [3]. - In cases where knock-in occurs but knock-out does not, Snowball and FCN can still yield returns, while Phoenix's cash flow is affected by the knock-in event [3]. - If knock-in occurs and the asset price is below the exercise price at maturity, losses may occur, with Snowball being the most adversely affected due to no cash flow during the holding period [3]. Group 3: Risk and Return Dynamics - The risk-return relationship indicates that Phoenix typically offers lower coupons than Snowball, while FCN generally has the lowest coupon rates [4]. Group 4: Market Timing Considerations - Proper market timing is essential, as no option structure guarantees profit in all market conditions [5]. Group 5: Delta and Volatility Analysis - All three structures maintain a positive Delta, indicating a bullish stance on the underlying asset, and are more suitable for moderate upward or sideways markets [7]. - The expected volatility is positively correlated with coupon rates, as higher volatility increases the likelihood of reaching knock-in conditions [8]. - The structures tend to be short volatility in most scenarios, making high volatility periods favorable for entry [10]. Group 6: Selection of Underlying Assets - The choice of underlying assets significantly impacts the performance of the structured products, with the China Securities 500 Index being identified as a suitable candidate due to its risk-return profile [14][16]. - The analysis of daily return distributions shows that the Hang Seng Tech Index has the lowest probability of extreme negative returns, making it a favorable option [14][15]. Group 7: Historical Backtesting and Timing Strategies - Historical backtesting indicates that FCN can effectively mitigate knock-in losses, making it a lower-risk option compared to Snowball [16]. - Rational timing strategies suggest that selecting more aggressive structures during low-risk periods and conservative structures during higher-risk periods can optimize returns [16]. Group 8: Structural Variations and Adjustments - The flexibility in setting barriers allows for various structural adjustments to balance risk and return, such as eliminating knock-in features or adjusting the knock-out thresholds [19].
