Baidu (BIDU) experienced a significant intraday decline of 5.21% during Thursday's trading session, reflecting broader negative sentiment in the technology sector.

The sell-off appears to be driven by investor concerns over inflated valuations for artificial intelligence (AI) concept stocks, which triggered a sharp downturn in the U.S. semiconductor sector. This panic sentiment quickly spread to Asia-Pacific markets, affecting related technology and internet stocks.

While some technology stocks showed resilience in certain regional markets earlier in the session, the overarching worry about AI stock valuations created downward pressure on major AI players like Baidu throughout the trading day.
