[Problem] To enable simulations in which the proportions constituting a portfolio of financial products such as shares held by a user are changed, to be easily performed. [Solution] A user terminal uses portfolio information received from a system server to display a portfolio screen 21 including a portfolio graph 30. The portfolio graph 30 is provided with: diagram sections 31-35 for shares of companies A to E which retain arc dimensions corresponding to the appraised values of trading-name shares (the shares of companies A to E) held by a user; and a cash diagram section 36 which retains an arc dimension corresponding to the amount of money in an account of the user. Boundary lines (such as the company-A-shares boundary line 31a) at clockwise-side ends of the diagram sections 31-35 for shares of companies A to E serve as holding amount indicators, and are capable of being moved by user operations. Clockwise movement operations are treated as buying operations, and anticlockwise movement operations are treated as selling operations. |
