Why Is Qualcomm (QCOM) Stock Price Down 7.17% Today, Sep 28? Chip-Sector Profit-Taking and 5.27% Treasury Yield Pressure QCOM

Qualcomm slid 7.17% amid broad semiconductor profit-taking and macro pressure as the U.S. 10-year yield pushed above ~5.27%, tightening financial conditions for rate-sensitive growth equities. The move appears driven more by sector-wide de-risking and "sell-the-news" dynamics after a strong Snapdragon-related rally than by new company-specific negatives. Near-term trading may track Treasury yields and chip peer performance.
