Looking for a reason to buy Baidu (BIDU -0.56%) today? In the video below, Fool contributor Kevin Chen fills you in on why Baidu is his top stock pick for April.

In the recent past, threats from competitor Qihoo 360 (QIHU.DL), China's slowing economy, and the economics of mobile have driven Baidu shares down. It seems like the company and its stock price may not recover anytime soon; not only does the company hover around its 52-week low, but it's been that way for several weeks now!

The reality is that, on a P/E basis, this is perhaps the best opportunity investors have had to buy Baidu in years. 

In the video below, Kevin addresses why Qihoo's growth may be slowing, and also examines overblown economic fears. Most importantly, he explains why "40 million" is the reason investors should be bullish on Baidu. Click the video to hear more about Baidu's promising long-term future.
