AT&T (T) is trading at $20.86 (-4.42%) as investors react to multiple company-specific catalysts. * Oppenheimer downgraded AT&T's stock from Outperform to Perform, citing structural threats from satellite broadband (Starlink) and skepticism regarding the company's fiber expansion strategy. * The stock is also experiencing selling pressure due to its removal from the Russell Top 50 Index, effective today, which may trigger institutional portfolio adjustments. * Lingering concerns around higher near-term leverage and the upcoming CFO transition further contribute to the cautious sentiment.
