This paper analyzes the franchise value change information of state-owned commercial bank. The franchise value change information shows that the franchise value of state-owned Commercial Bank is descending. Along with the descending of the franchise value, state-owned commercial bank strengthens its high risk investment motive when it chooses its investment strategy. State-owned commercial bank tends to run the high risk of investing securities because its investment variety is very sparse. Based on the theoretical principle of how to control securities investment risk, this paper proposes some countermeasures and suggestions that state-owned commercial bank strengthen the control of its securities investment risk in order to perfect its investment strategy.展开更多

The financial market is composed of a risk-free asset and a risk asset with an uncertain price process described by an uncertain differential equation. An optimization problem is assumed that its objective is a nonlinear function of decision variable. By deriving the equation of optimality, an analytical solution is obtained for the optimal delay investment strategy, and the optimal delay value function. Finally, an economic analysis and numerical sensitivity analysis are conducted to evaluate the research results.展开更多
