BIDU is trading at 3.1% down now at $118.33 after a recent analyst downgrade to 'sell' by Wall Street Zen on October 18, 2025, which has weighed on investor sentiment[3]. There are no new company-specific catalysts today, with the only recent announcement being Baidu's scheduled Q3 earnings release on November 18, 2025[1][2][5]. The broader market is mixed, but BIDU's decline is notably sharper than major indices, suggesting the downgrade and lack of near-term positive news are driving today's drop.
