Why Is Cipher (CIFR) Stock Down 8.70% Today, Sep 9? Data Center Rally Cools as Higher Oil and Yields Trigger Profit-Taking

Cipher Digital (CIFR) slid 8.7% as profit-taking followed a recent rally and a broader risk-off tape emerged alongside $100+ Brent and higher U.S. yields. The move appears driven by positioning and macro-sensitive equity de-risking rather than new company-specific negatives, keeping short-term trading focused on whether the selloff stabilizes or extends as AI/data-center momentum cools.
