Challenge   I ’m a portfolio manager . In stock market , one main problem is that people are flooded by too   much information and too many opinions . For example , when President Trump declared a trade   war towards China , ten analysts may have eleven opinions . We have more than enough data ,   such as employment rates , imports & exports , capital investment , company profits and etc , but   we still have no ability to forecast what will happen in the future .      Selection   The difficulty is that one factor may cause a series effects . Some of them have positive feedbacks   and some negative . When these effects mix , people have no ability to deal with the results . It ’s   not linear correlation . Under such circumstance , Mind Mapping is a very powerful tool for me ,   because it can visualize the complex correlations between factors and make them easier to   understand .      Application and Insight   When I use Mind Mapping in analyzing the economy , I will outline the main first tier effects . Then   I will follow each effect to generate consequent results .    As I demonstrate following , a trade war will decrease China ’s exports . In the first way , decreasing   exports will lower China ’s money supply , and then interest rate is forced to rise . In the second   way , decreasing exports will reduce Chinese companies ’ profits and solvencies . Both ways lead to   the same point , China ’s leverage . Since a large ratio of Chinese companies depends on selling   products overseas , it may cause a serious result . The bankruptcy rate in China may rise , and slow   down both global and US economy growth . Then US may or may not change the trade policy   depending on how slow growth US can stand . 

 Using Mad Mapping , I consider more factors in my analysis . It helps me clarify the complexity .   Some factors may be missed in linear analysis . But there are still some limits . The results ca n’t be 

 very accurate because it ’s impossible to know how much a company ’s profitability will affect its   solvency .      Approach   I ’m sure I will keep using Mind Mapping in my analysis as well as other areas in my life . The tool   helps me find important unknown factors and hidden relationships between known factors .    The course is very helpful to me as well . I learnt to live with failures and change my mind set to   adapt new things . Thank you very much .
