尽管经济数据向好、美联储降息支持且股市接近高位，但美国金融市场正在经历一场微妙的转变。 彭博汇编的数据显示，本月，此前深受散户青睐的美国杠杆ETF遭遇资金流出约70亿美元，为2019年有 记录以来的最高水平。 与此同时，随着杠杆押注的平仓，数字货币市场一度蒸发约3000亿美元市值。此外，美股主要股指也结 束了连续上涨的势头。标普500指数和纳斯达克100指数均录得一个月来的首次单周下跌。 以三倍做多半导体指数的Direxion Daily Semiconductors Bull 3x Shares（SOXL）为例，尽管该基金本月 上涨了31%，但投资者仍从中撤出了超过23亿美元。 这清晰地表明，部分交易员选择在上涨时离场。 同样，旨在放大特斯拉公司股价波动的TSLL基金，也正迎来其有史以来最大的月度资金流出，规模已 达约15亿美元。 Interactive Brokers的首席策略师Steve Sosnick评论道： "活跃的交易员仍然愿意追逐快速变动的股票，但他们逢低买入和追高的兴趣确实减弱了。 我不会称之为'消化不良'，或许更像是在饕餮盛宴后的一点'食物昏迷'。" 值得注意的是，引领此次撤退的正是那些曾被 ...

野村警告，尽管AI驱动的美股牛市基础稳固且受多重利好支撑，但市场已积累显著下行风险。当前投资者过度看涨，期权市场看涨需求激增，且科技巨 头间的"循环投资"模式令人担忧。报告警告称，市场处于极端净多头和负伽马状态，一旦出现催化剂，可能因去杠杆化引发快速剧烈回调，因此现在放 弃对冲策略是危险之举。 野村证券最新分析指出，尽管人工智能驱动的美股牛市基础依然稳固，投资者仍可参与其中，但市场已积累了显著的下行风险，现在放弃对冲策略将是 危险之举。 在策略师Charlie McElligott看来， 当前市场正处于一场"AI引发的狂热"之中， 形成了一个良性循环，推动股指不断创下历史新高。这种持续的上涨正 在迫使此前持怀疑态度的投资者追高买入，进一步助推了这轮涨势。 然而，McElligott警告称，尽管对冲策略可能会拖累短期表现，但投资者"现在绝不能放弃对冲"。他指出， 市场在极端的净多头仓位、负伽马、以及潜 在的波动率挤压风险下，正面临显著的"下行凸性"（convexity to the downside），一旦出现催化剂，跌幅会因负伽马、高杠杆和拥挤多头被强制平 仓而呈指数级放大，形成越跌越快的"加速下坠"曲线。 ...

智通财经APP获悉，华尔街金融巨头美国银行的股票策略师团队建议投资者们倾向对冲策略，以防范在美股市场屡创历史新高的同时，八月份可能突然爆发 的股票市场动荡。八月历来是全球股市波动剧烈的时期，而最近几周市场却异常平静，这也令华尔街不少投资机构高呼在对冲成本低廉且低波动时期趁 机"逢高卖出"或者采取对冲策略保护投资组合收益。 "在流动性不足方面，八月往往会显露抛售獠牙。"美国银行的美洲股票衍生品研究主管尼廷·萨克塞纳表示。他回忆起自2011年以来该月出现过三次剧烈波 动导致的抛售冲击。 德意志银行统计数据显示，通常在指数上涨时买入、下跌时卖出的商品交易顾问(CTA)，目前持有的股票多头头寸处于94%分位——为2020年1月以来的最高 水平。德银指出，这既表明对股市的信心，也意味着如果市场环境变化，可能出现剧烈反转的风险会加大。 为了对冲这种抛售风险，萨克塞纳团队建议进行所谓的"W形交易"。该策略首先卖出在市场保持平稳运行时能够获利的衍生品或其他投资工具，然后利用所 得收益支付对股票突然大涨或暴跌进行更大规模下注的成本。目前，第二步对冲成本相对便宜，这也是为何华尔街策略师们建议投资者在廉价之际选择对冲 策略，因为市 ...
