How to search for under-valued stocks?

I think most of the people are recommending you some stocks with lower PE rate such as 133, HSBC would be one of them. In fact, you should compare with other same business nature company like PetroChina Co., Ltd. (857) and Exxon, 875's PE rate now is just 19.xx but considerly very low when compare to 1919 or even Alibaba which is talking about 250~300%, right? But when compare to Exxon, 857 is considerly high, but it's high is not without reason, since the publication of A stocks in China, and 857 is became the highest value and biggest Petro company in the world, we could understand what why it's PE rate is higher than her competitors and which is acceptable.

U can buy some investment magazine, most of them have many recommendations over there.

Hope can solve ur query. ^ ^

PE will change as the company release it's financial report, therefore it is important to research it's background.
