It easily lets enthusiastic investors to follow Warren Buffet’s stock portfolio. By referencing the investment portfolio of the world most famous investment master, the user can take heed and make good decision on his own stock investment. In addition, the app does list down some common investment knowledge such as key financial ratio which is used in stock valuation for user to use as daily reference. The app can serve as a mini stock investment reference on the go. This, hopefully, will assist in increasing the level of efficiency for personal finance management.
