On October 13, 2025, Moody's Corporation (MCO) closed at $473.72, down 2.14% from the prior session, following significant negative news: the SEC fined Moody's and other major credit rating agencies a total of $49 million for recordkeeping failures, and Moody's itself downgraded the U.S. credit rating to Aa1, sparking market jitters. These regulatory and macroeconomic developments triggered a sharp selloff and heightened volatility, with investor sentiment turning cautious as the stock approached key support levels. No other major company-specific news was reported, and the broader market remained flat, indicating that MCO's decline was primarily driven by these direct company events.
