A Survey on natural persons and corporate person-hoods' investment behavior in Tehran Stock Exchange, in time of sanctions (with concentration on strategic investment in uncertainty)

In recent years, Iran has been subject to severe international sanctions. Sanctions have caused additional ambiguity and uncertainty that can change investor behavior. The extant research considers recent scientific strategic investment theories in uncertainty, and considers how investors use this method in current conditions of Tehran stock exchange, in order to determine how much these theories are applied in investment decisions. It is noteworthy that studying recent scientific research on strategic investment in uncertainty reveals that prospect theory; cumulative prospect theory, real option theory, and behavioral finance (which are psychologically and behaviorally correlated to one another) are considered as basics of new strategic investment in uncertainty. In the present research,
Spearman and linear regression are used for analyzing the research hypotheses. A single sample t test is used to describe investors’ behaviors, and independent two-sample t test is
used to compare natural persons’ society and corporate personhoods’ society. Despite the research results indicating that investors find the investing environment replete with uncertainties, the impact of the uncertainty on investors’ approach to learning and applying new strategic investment methods, while controlling for behavioral biases, is not proven.
