U.S. stock index futures diverge as the semiconductor sector faces pressure for a second consecutive day

U.S. stock index futures showed mixed performance on Thursday as the trend of investors pulling out from semiconductor stocks continued into a second trading day. The market has shifted focus from the initial relief rally following the U.S. midterm elections to evaluating the potential impact of Democratic control of Congress. Concerns that full Democratic control might lead to strengthened regulation of U.S. data centers—and thus drag down semiconductor demand—continued to weigh on chipmakers and storage chip stocks. Additionally, disappointing market reactions to earnings reports from Arm and Qualcomm further intensified the selling pressure. However, traders cautioned that the overall market movement should not be interpreted as a fundamental shift in investor preference. JPMorgan's equity derivatives team believes that this sector rotation is driven more by market position adjustments than by a true change in fundamentals. In a report, JPMorgan’s Christina Jones stated that they have yet to see clients broadly rotate into other sectors or chase previously underperforming stocks. In her view, genuine fund rotation has been limited to the technology, media, and telecommunications sectors. Jones also pointed out that investors are showing a clear preference for holding high-quality large-cap stocks, particularly companies with clear access to financing and substantial computing power resources, such as some mega-cap technology firms.
