1. Report Industry Investment Rating The report does not provide an overall investment rating for the options market. However, it offers rating criteria for different types of bonds: - **Interest - rate bonds**: Based on the net price change of interest - rate bonds within 3 months after the report date. Ratings include "Overweight" (interest risk decreases, net price has upward potential), "Neutral" (interest risk is stable, net price has minor fluctuations), and "Underweight" (interest risk increases, net price has downward potential) [93]. - **Credit bonds**: Based on the net price change of credit bonds within 3 months after the report date. Ratings include "Overweight" (credit risk decreases, net price has upward potential), "Neutral" (credit risk is stable, net price has minor fluctuations), and "Underweight" (credit risk increases, net price has downward potential) [94]. - **Convertible bonds**: Based on the price change of convertible bonds relative to the CSI Convertible Bond Index within 3 months after the report date. Ratings include "Overweight" (convertible bonds outperform the CSI Convertible Bond Index), "Neutral" (convertible bonds perform in line with the CSI Convertible Bond Index), and "Underweight" (convertible bonds underperform the CSI Convertible Bond Index) [95]. 2. Core View of the Report In a volatile market environment, options, with the natural advantage of separating rights and obligations, can provide opportunities to seek excess returns while controlling risks. Attention should be paid to the effect of expanding the investment boundary brought by options and related investment portfolios [1]. 3. Summary by Relevant Catalogs 3.1 Option Overview - **Option Definition and Key Elements**: An option contract is a standardized or non - standardized contract that allows the buyer the right to buy or sell an agreed underlying asset (including futures contracts) at a specific price in the future. Key elements include the underlying asset, right type, exercise price, and expiration date. Options are "right" certificates rather than "ownership" certificates, and the transaction is the transfer of rights and obligations, not the transfer of real - asset ownership [1][19]. - **Classification of Domestic Options**: Chinese options can be divided into on - exchange options and over - the - counter (OTC) options. OTC options are mostly non - standardized and are usually customized between institutional investors, and individual investors generally cannot participate. On - exchange options can be further divided into two categories: ETF options based on securities accounts with ETFs as underlying assets, mainly listed on the Shanghai and Shenzhen Stock Exchanges; and options based on futures accounts, including stock index options listed on the China Financial Futures Exchange and commodity options listed on various commodity exchanges [1][24]. - **Advantages and Disadvantages of Option Investment**: Advantages include the separation of rights and obligations, which can improve capital use efficiency; the separation of risk and return, which can prevent extreme price - fluctuation risks; and the ability to combine with basic products to enrich investment strategies. Disadvantages include the potential for the time value of options to be wasted, the influence of volatility on option value, and the requirement for both correct direction and timing in option investment [2][3] 3.2 Option Pricing and Greek Values - **BS Formula for Option Pricing**: The Black - Scholes (BS) model is the theoretical basis for pricing European options globally. In reality, since the volatility of the underlying asset in the future cannot be observed, the concept of implied volatility is introduced, which is a core factor affecting option prices [32][33]. - **Delta**: Measures the change in option price caused by a 1 - unit change in the price of the underlying asset. It reflects the linear sensitivity of the option price to the price of the underlying asset. It is mainly used to linearly reflect the impact of small - scale price changes of the underlying asset on the option price and can be used to construct investment portfolios to hedge risks [34][36]. - **Gamma**: The second - order partial derivative of the option price with respect to the price of the underlying asset. It measures the change in Delta caused by a 1 - unit change in the price of the underlying asset. It is mainly used to prevent extreme price - fluctuation risks [38][39]. - **Theta**: Measures the change in option price caused by a 1 - unit reduction in the remaining time. The time value of an option is constantly decreasing, so Theta is always negative. It represents the cost for the buyer and the income for the seller [41][42]. - **Vega**: Measures the relationship between a 1 - unit change in the volatility of the underlying asset and the change in option price. Vega is always positive, indicating a positive correlation between option price and volatility. Implied volatility can be used as a warning indicator of potential risks [43][50]. - **Rho**: Measures the change in option price caused by a 1 - unit change in the risk - free interest rate. In the ideal conditions defined by the BS formula, the Rho of a call option is positive, and that of a put option is negative. However, for commodity options, the situation may be different [55]. 3.3 Option Trading Strategy Analysis - **Single - Option Trading Strategy**: Buying a call/put option indicates a bullish/bearish view, while selling a call/put option indicates a non - bullish/non - bearish view. Buying options can control risks while building positions. Options may have a higher leverage ratio than futures, showing both safety and risk. For investment, options close to at - the - money should be selected; for speculation, relatively out - of - the - money options are preferred. Option investment is more suitable for short - term trading [7][68]. - **Multi - Option Portfolio Strategy**: By using two or more options to construct an investment portfolio, investors can qualitatively express bullish/bearish views and quantitatively describe the degree of bullishness/bearishness. For example, a bull call spread can express a moderately bullish view, and a bear put spread can express a moderately bearish view. For assets in a long - term sideways state, investors can construct volatility portfolios through double - opening (double - buying or double - selling) strategies. The timing of opening positions is the key to the profitability of double - opening strategies [74][86]. - **Option and Spot Portfolio Strategy**: Options can be combined with spot assets to control risk exposure and achieve conditional risk hedging. Buying spot and put options can form a protective put portfolio, and buying spot and selling call options can form a covered call portfolio. The choice of hedging ratio is crucial [87][90].
