1. Baidu have had low valuation due to its stagnant growth of its core business - search engine in China, however, it enjoys a significant moat in this segment as it is the largest market share holder - therefore has network effect.
2. Baidu had been investing significantly in developing AI and autonomous driving over the past few years. Its Apollo project is as good as (if not better), than Google's Waymo. However, Apollo is valued at $1.3 billion only (3% of Baidu's market cap) due to Baidu's core business growth, and unclear roadmap of monetization of Apollo. But, Google's Waymo is valued at $30 billion. It is worth noting that only Waymo and Apollo achieved the L4 auto driving, where they begin 1000+ testing of full self driving on road. Tesla's autonomous driving had been recording data of man's driving, while Waymo and Apollo records data on full self-driving.
3. Recently, Baidu began its robotaxi test drive in Beijing, which received huge responses, had cause the stock price to break out its few months resistance level. Therefore, I believe that the break out from a technical perspective may signify huge support for Baidu in addition to its near term upward trend (typical higher lows).
4. Despite full self driving is still years before it could be full commercialised, Baidu's Apollo had also been providing smart city solutions to assist with provinces of China to solve the traffic issue. In Guangzhou, Baidu received RMB 450 million project. This may be the key monetisation way for Baidu in the next 2-3 years, which is very likely given the traffic issues have been causing waste of resources for China, thus the government is likely invest in smart transportation through Baidu. Therefore, we can expect more projects given by the government, which would be a catalyst moving forward.
5. In mid September, Baidu's management noted that re-listing in Hong Kong would gives it a higher valuation that it currently has. Therefore, we may expect a catalyst from this part.
Also, the current risk to reward ratio is worth betting on. If it breaks the current support ( breaking the low of the uptrend), then we might have to look for another entry point. However, recent pull back after break out provide a great entry point.
