Baidu Falls, Artificial Intelligence Push In Limbo After Shake-up?

Baidu (BIDU) stock sold off Friday as analysts pondered whether its push into artificial intelligence will stall in the wake of its chief operating officer stepping down. COO Qi Lu, a former Microsoft (MSFT) executive, headed Baidu's artificial intelligence research. Baidu is just one stock to watch for artificial intelligence developments. The China-based internet search leader fell 7.4% to 259 on the stock market today, tumbling out of a buy zone. Credit Suisse downgraded Baidu to neutral on the management shake-up, announced late Thursday.
