核心观点
- 2025年股市抛售：这次抛售由两个阶段组成，先是科技股领跌的缓慢下跌，然后是“解放日”关税冲击引发的剧烈、广泛下跌。这种抛售的特点介于2020年的崩盘和2022年的缓慢下跌之间。
- 对冲策略表现：在抛售期间， Vanilla期权对冲策略（如SPX看跌期权）表现良好，尤其是在短期到期的情况下。VIX期货/期权对冲策略在抛售的第二阶段表现良好。趋势跟踪策略（CTAs）表现最差，因为多个资产类别出现了突然的趋势反转。短期对冲策略提供了更好的性价比。
- “抛售象限”分析：研报提出了“抛售象限”框架，将抛售分为凸型崩盘、缓慢下跌、技术性狂热和温和修正四种类型。大多数高效、低成本的系统性对冲策略针对的是凸型崩盘，这使得其他象限的管理更加困难。
- 可靠性和可保留性：可靠的对冲策略（如合成看跌期权和日历领圈）虽然成本高，但仍然很难获得。研报介绍了SPX看跌期权的“获利了结”机制，可以提高对冲策略的可保留性，尤其是在市场快速反弹的情况下。
- “凸型抛售”的价值：对于更严重的凸型市场抛售，在平静的市场中被低估的资产上寻找低成本对冲策略是有价值的，因为这些资产在系统性冲击期间会变得非常敏感。
关键数据和研究结论
- SPX跌幅：2025年2月至4月，SPX跌幅约为20%，其中2月至3月下跌了约10%，4月至5月下跌了约10%。
- VIX波动率：在抛售的第二阶段，VIX波动率大幅上涨，但随后迅速回落。
- 对冲策略表现：SPX vanilla option hedges, especially short-dated, delivered strongest performance across both legs of the selloff. 'Vanilla' VIX futures & options-based hedges also did well, though their gains were largely accrued in the second, more abrupt selloff. But, as usual, vanilla hedges were quick to give back gains in the rebound. In contrast, convex hedges, e.g. DCON, IDMO, struggled in the grind-lower phase, had modest returns vs. history but were more effective in retaining gains. Meanwhile, trend-following strategies (CTAs) were the weakest performers, hit by sharp and sudden reversals across multiple asset classes.
- DOP策略：SPX grind lower (DOP) hedge was particularly efficient during the Feb/Mar leg, outperforming among all the hedges we track. Designed for slow, sustained drawdowns without a proportionate rise in volatility, it has historically delivered strong protection when most convex hedges faltered.
- 获利了结机制：添加获利了结机制可以提高SPX看跌期权的可保留性，尤其是在市场快速反弹的情况下。
