A problem of geopolitical actor strategy quality estimation (socio-economic, military-political etc.) with a view to increasing or decreasing the assets market value is formalized and solved in the paper. Aiming to solve this problem the random process of assets market value changes is introduced as random function X(t). The geopolitical actor assets market value changes are represented as a random process and analyzed with the help of this random process's characteristics. Making use of these characteristics the quality of the geopolitical actor strategy is estimated. An illustrative example is given.
