Why Baidu Stock Plunged Today
Baidu shares (NASDAQ: BIDU) fell about 11% on Tuesday after the company’s Q2 results disappointed. Baidu reported revenue of RMB 31.3B, down 4% YoY, and diluted EPS of RMB 5.74 per ADS, down 72%. Analysts expected RMB 31.95B revenue and RMB 9.84 EPS. Online marketing revenue fell 19% YoY.

Why it matters
Baidu’s revenue and EPS misses versus consensus, plus a 19% YoY decline in online marketing, likely drive the repricing. AI segment growth and higher AI cloud spend are positives but not enough to offset the magnitude of the earnings miss.
