U.S. retail investors have recently increased their bullish put and inverse ETF positions, but overall they still maintain a net buying stance. Tech stocks are seeing a pullback, yet investors continue to deploy strategies at lower levels.

自 4 月以来,美股散户的交易方式出现变化。研究机构 Vanda Research 的数据显示,散户直接买入股票的力度减弱,但用于防守的看跌期权买盘明显上升。与此同时,嘉信理财的数据又显示,散户整体并未转为空头,科技股回调时仍有持续买盘。

看跌期权买盘明显增加

Vanda Research 统计显示,围绕 2026 年散户最偏好的 12 只热门股票,看跌期权买入量较第一季度接近翻倍。相关买盘占净现金买入量的比例,也从约 26% 升至 110%。

Vanda 全球股票策略师 Kaidi Meng 表示,今年散户不再像过去那样在下跌时普遍加仓,而是更倾向于在个股之间快速切换,或者在买入股票的同时配置保护性看跌期权。

反向 ETF 也成为散户重要的防守工具。自 4 月中旬以来,科技类 ETF 的交易数据表明,散户直接承担风险的意愿下降。看涨科技 ETF 的活跃度下降约 50%,看跌 ETF 的活跃度降幅约为 35%。

风险敞口收缩,但未全面转空

Meng 认为,杠杆工具和 ETF 策略更普及后,散户的风险管理方式已不同于往年。资金流向显示,对冲需求正在增加,多头风险敞口整体有所收缩。

部分分析人士认为,这种变化可能与散户在多年“逢低买入”获利后选择部分兑现有关。也有部分资金转向波动更高的投机性股票、杠杆 ETF 和预测市场。

嘉信数据仍显示净买入

嘉信理财披露,7 月市场波动加大,但平台客户仍保持净买入,买家数量超过卖家两倍。衡量客户交易活跃度的 STAX 指数从 6 月的 59.12 升至 7 月的 59.80,连续第三个月上升,并创 2022 年 1 月以来最高水平。

嘉信的研究显示,面对科技板块回调,散户更倾向于买入波动较大的热门个股,而不是继续持有走势平淡的标的。曾长期处于交易核心位置的英伟达,7 月罕见跌出 STAX 最活跃个股前五,显示短线资金正向其他高弹性股票轮动。

期权策略转向防守加布局反弹

嘉信理财首席交易和衍生品策略师 Joe Mazzola 表示,不少投资者正在卖出英伟达、美光和闪迪等 AI 概念股的看跌期权,以获取较高权利金。

除个股期权外,散户在 8 月 7 日当周也适度增持景顺 QQQ 信托的低成本看跌期权,用于对冲更广泛的科技板块下行风险。Mazzola 认为,当前组合显示出一定防守姿态,但整体对冲力度仍不算激进。

从交易结构看,部分投资者一边卖出看跌期权获取权利金,一边买入看涨期权,为后续反弹预留仓位。这意味着散户虽然提高了防守比例,但并未完全放弃对科技股和成长股继续上行的押注。
