Notifying Investors in Time - A Mobile Information System Approach

Within the non-institutional investment sector, private investors are usually not able to monitor all new public available information which might have significant impact on their portfolio value. This scenario might be a promising domain for mobile push information services. In order to prove these potential capabilities, this paper examines short term security price reactions following new information available to the capital market. After identifying determinants of the observed price effects and effect delays, a suitable mobile push infrastructure is introduced, which can provide an investor notification in time. It is shown how personalized combined mobile push/pull services can provide a reasonable proportion of sending portfolio relevant information immediately and reducing the level of user-intrusiveness to a manageable dimension.
