突发：纳斯达克100指数ETF（QQQ）的空头持仓量已升至约8200万股，创2023年3月以来最高水平。

过去几周，QQQ的空头持仓量激增1800万股，增幅高达28%。

今年以来，QQQ的空头持仓量几乎翻了一倍。

与此同时，标普500指数ETF（SPY）的空头持仓量却呈现相反趋势。自今年3月以来，SPY的空头持仓减少了3000万股，目前降至约9200万股，接近至少五年来的最低水平。

作为对比，在2022年美股熊市期间：

- QQQ空头持仓峰值：约9000万股

- SPY空头持仓峰值：约1.8亿股

这意味着，目前QQQ的空头持仓规模已经接近2022年熊市期间的峰值，而SPY的空头持仓却处于历史较低水平。

当前市场对科技股的做空力度非常高。

美股大数据 StockWe.com解读：这一变化表明，空头仓位正在明显向纳斯达克100指数集中，科技股面临更大的对冲和看空压力。不过，空头持仓增加并不必然意味着科技股即将暴跌，因为其中也可能包含机构的组合对冲及套利交易。如果后续科技股财报超出预期，大量空头仓位反而可能成为空头回补行情（Short Squeeze）的推动因素。

Short interest in the Nasdaq 100 ETF, QQQ is up to ~82 million shares, its highest since March 2023.

Over the last several weeks, this figure has surged +18 million shares, or +28%.

Year-to-date, short interest in QQQ has nearly doubled.

Meanwhile, short interest in the S&P 500 ETF, SPY, has declined -30 million shares since March, to ~92 million shares, near its lowest in at least 5 years.

By comparison, during the 2022 bear market, short interest peaked at ~90 million shares for QQQ and ~180 million shares for SPY

Short interest in tech is very high right now.
