In the morning of July 31th, Guo Dongchen, the 2012 top ten financial planner, came to the summer camp to explain the importance of due diligence in enterprise growth. Mr. Guo analyzed the points in two aspects- stock due diligence and equity due diligence. His opinion can be summarized as follows: two advantages-industry advantage and enterprise advantage; three patterns-business pattern, profit pattern, marketing pattern; four indicators-operating income, operating profit, net profit, growth rate; five structures: equity, senior executives, business, customers, suppliers. Mr. Guo patiently explained the jargon in the cases, and answered the questions one by one in details.
