Disclosure: I am long BIDU.
Summary
- Baidu will maintain its leading position in PC search and extend its leadership into the mobile search business.
- Mobile payments, map services, online video and app distribution will be key revenue and earnings growth drivers in coming years.
- Stock is trading at a 40% discount to fair value; ramping margins could be a long-term catalyst.
Baidu's (BIDU) core search engine business is expected to continue delivering solid revenue growth over the next several years, largely driven by China's rising Internet user base. Baidu recently entered the mobile segment by providing mobile payments, map services, online video and apps. These initiatives are not yet generating meaningful revenue, but I believe they will become long-term revenue growth drivers on the back of rising demand for mobile services.
Even with Baidu shares up more than 80% over the last 12 months, the stock is still trading at a substantial discount to its Internet peers. I believe this is unjustified given the company's robust growth, ramping margins and wide economic moat. Taking these factors into account, I believe Baidu is one of the best investment opportunities of 2014.
Business Overview
Baidu is the dominant Chinese search engine, with over 70% market share, and the second-largest search engine in the world behind Google (GOOG,GOOGL). The Baidu.com website is the most trafficked website in China, and the "Baidu" brand is ranked as the most valuable Internet brand in China. The company generates revenues primarily from pay-for-performance advertising ("P4P"). Its P4P platform helps connect millions of Internet search users to its more than 753,000 marketing customers who pay it a fee based on click-throughs for priority placement of their links in the search results. Baidu was founded in 2000, and listed on the Nasdaq in 2005.
Baidu Benefits From a Tremendous Network Effect
Baidu is the dominant Internet search engine in China, with over 70% search market share as of 1Q14. Some investors have been concerned that Baidu will eventually lose its market share advantage to competitors such as Qihoo 360 (QIHU) and Sogou (including Soso). Although rising competition is a risk one should consider, I still believe Baidu will remain the dominant Chinese search engine going forward, because the company benefits from a tremendous "network effect."

Baidu ended 2013 with more than 753,000 marketing customers, making it the largest Internet search engine in China by some distance. This customer base has grown at an impressive 41% per annum between 2003 and 2013, and will likely continue growing at double-digit rates for the foreseeable future. More customers have led to more information on Baidu's online platforms, and consequently, attract more search engine users. This creates a self-reinforcing network effect that is very difficult for its competitors to replicate, since it takes a fairly long time for other companies to achieve a user base of similar size. Moreover, millions of Internet users rely on Baidu's dominant online platform to connect with each other and share information and knowledge. It is highly unlikely for users to give up the massive network and information source by switching away from Baidu.
I believe the increasing Internet penetration in China will help widen Baidu's economic moat over time. First-time Internet users are more likely to choose Baidu as their preferred search engine, simply due to the fact that it is probably the one they are most familiar with. In my opinion, this gives Baidu an enormous competitive advantage. The Internet penetration rate in China has increased steadily from 6% in 2003 to just below 46% in 2013. However, this penetration rate is still low compared to developed countries. The Unites States, for example, has a penetration rate of nearly 80%. Over the long term, the growth in the number of Internet users in China will contribute toward the growth in the number of Baidu users. I believe this will further strengthen the company's network effect and widen its economic moat.

Mobile Business Will Be a Long-Term Growth Driver
The number of mobile Internet users in China has grown at 47% per annum between 2007 and 2013, and reached 500 million by the end of 2013. Still, considering China has a population of over 1.3 billion, this represents a mobile Internet penetration rate of only 37%. Although, with the continued rapid adoption of mobile devices in China, the number of mobile Internet users is likely to see further growth in coming years.

I believe Baidu is the strongest-positioned to benefit from the fast-growing mobile search market. According to the 2013 survey on "Internet User Search Behavior" by CNNIC, over 89% of mobile Internet users in China picked Baidu as their favorite mobile search engine, dwarfing its main competitors Qihoo 360 and Sogou (including Soso). This suggests that Baidu's mobile search will eventually achieve success similar to its PC search business.
