Baidu slid from a $82.60 open to roughly $78.23, with no recovery attempt holding through regular trading hours.

A 5.3% decline erased better than $1 billion from Baidu's $21.5 billion market value in a single day, the kind of reset that changes how institutional investors size positions.

The $78 level is now the number to watch: a close below it removes a price floor that has drawn buyers in recent sessions and opens the door to further downside pressure. A close above $78 would suggest the selling found a natural limit.

Baidu carries meaningful exposure to both China's search advertising market and the competitive AI landscape, so a move of this size signals shifting sentiment about either business line, or both. Keep an eye on the volume behind the decline for evidence of seller conviction.
