期货日报期权研究院特邀讲师刘阳在最近一场直播中直言："市场70%~80%的时间都在震荡，只想抓趋势，等于 主动放弃了大部分赚钱的机会。" 刘阳不仅戳破了"完美择时"的幻想，更带来了一套普通交易者也能上手的期权组合策略，让你在震荡行情的"垃圾 时间"里也能构建出自己的"收益护城河"。 震荡是常态 刘阳认为，市场70%~80%的时间都处于震荡状态。多数趋势交易者厌恶震荡市，但逃避就等于放弃了绝大多数的 时间价值。真正的交易高手，必须先学会与震荡行情共处，并从中找到盈利机会。 此外，刘阳表示，右侧交易追求"起爆点"，可以采用"守株待兔"策略，提前布局并忍受震荡行情，避免频繁地追 涨杀跌。 单腿买权是散户"坟墓" 直播中，刘阳对"期权的裸买方"（单腿买权）进行了非常深入的剖析。他将单腿买权比喻为"买彩票"：高盈亏 比，胜率极低，看似"亏损有限，盈利无限"，实则胜率远低于50%，对择时的能力要求极高。 对于幸存者偏差，刘阳认为，市场上仅有个别顶尖高手能通过单腿买权持续盈利。对于大多数普通交易者来说， 这无异于持续"烧钱"。 "如果你在期货市场本身都无法稳定盈利，那么单腿买权对你而言就是'雪上加霜'。"刘阳说。 蝶式策略 ...

Report Industry Investment Rating No relevant content provided. Core View of the Report The report, taking CSI 1000 index options as an example, analyzes the suitability of option spread strategies in a market scenario where the market is expected to rise in the medium to long - term and fluctuate within a range in the short - term. It introduces various option spread strategies, including vertical spread, ratio spread, horizontal spread, diagonal spread, and butterfly spread, and studies their application scenarios through historical data backtesting [3][52]. Summary by Directory 1. Option Portfolio Strategy Construction Ideas - **Non - linear Profit and Loss Structure of Options**: Options have a non - linear profit and loss structure, which provides diverse strategy choices for investors. When constructing option portfolio strategies, multi - dimensional factors such as option position PCR, implied volatility, and the direction of the underlying index should be comprehensively considered [8]. - **Option Position PCR**: As of November 28, the position PCR of CSI 1000 index options was 97.48%, at the 84.9% quantile level since 2023. The decline in position PCR since mid - November indicates a weakening of market sentiment, and the market sentiment remains unclear as the position PCR has not risen above 100% [9]. - **Implied Volatility**: As of November 28, the at - the - money implied volatility of CSI 1000 index options was 17.32%, at the 33.7% quantile level since 2023. Since the implied volatility is at a low level, there is limited room for further decline. When constructing option portfolio strategies, investors should consider holding a positive vega risk exposure [11]. - **Index Fundamental Analysis**: Policy stability of macro - demand, policy support for technological innovation, and continuous inflow of funds into the stock market form the core logic for the medium - to - long - term upward movement of the index. However, due to the risk of the AI asset investment bubble overseas and the increase in the willingness of funds to take short - term profits, the index may fluctuate within a range in the short - term [15]. 2. Introduction to Option Spread Strategies - **Vertical Spread**: It can be divided into bull spread and bear spread. Bull spread is suitable for a moderately bullish market, and bear spread is suitable for a moderately bearish market. This strategy can reduce the cost of premiums and control potential large losses [26][27]. - **Ratio Spread**: It is an asymmetric spread strategy, including bullish ratio spread and bearish ratio spread. It is suitable for investors with specific expectations for market direction or volatility, with the core logic of using option premium income and time - value decay characteristics to pursue profits while controlling risks [30]. - **Horizontal Spread**: Also known as calendar spread, it takes advantage of the asymmetry of time - value decay. It is suitable for a market environment of "price consolidation + rising volatility" and is a time - arbitrage tool in a neutral market [35]. - **Diagonal Spread**: It combines the characteristics of vertical spread and horizontal spread, aiming to profit from the difference in time - value decay and price fluctuations. It can be constructed using call or put options and is suitable for investors with a clear directional judgment on the market but who also want to control risks [37]. - **Butterfly Spread**: A three - leg combination suitable for a range - bound market. It allows investors to lock in a price range and profit when the price of the underlying asset fluctuates within a narrow range, with strictly limited risks [39]. 3. Empirical Comparison of Option Spread Strategies - For the CSI 1000 index in the range of 7000 - 7600, different spread strategies can be selected to control the risk exposure of "bottom - fishing". Through backtesting, the overall performance ranking of strategies is ratio spread > butterfly spread > bull put spread > bull call spread > horizontal spread > diagonal spread, with the diagonal spread being the only losing strategy [45][47]. - The returns of vertical spread strategies are mainly affected by delta, while those of horizontal spread strategies are mainly affected by vega and theta. During the index's rebound, vertical spread strategies perform well, while during the index's decline, horizontal spread strategies may stop losses and repair, and the butterfly spread strategy maintains a relatively stable growth [50][51]. 4. Summary The report concludes that option spread strategies are suitable for a market scenario where the market is expected to rise in the medium to long - term and fluctuate within a range in the short - term. Different strategies have different profit and loss characteristics and application scenarios. For different Delta, theta, and vega scenarios, the optimal spread strategies also vary [52].
