neurological functions of ceo investment based on varimax analysis and rotated matrix in q typology

Chief executive officers (ceo), as the central pillar directing companies at the capital market level, plays a critical role in making investment decisions to decrease agency costs and maximize shareholders’ wealth; however, their psychological attitudes and perceptions lead to different investment functions of these companies in a competitive market. accordingly, this study aimed to detect the propositional arrays of the investment functions using q analysis in order to identify the ceos’ mental typology in distinguishing investment functions. the present study was carried out with the participation of 13 ceos from tehran stock exchange companies during a one-year period (2018-2019). the study encompassed two different phases. in the first phase, content analysis was used to identify the phrase q of the ceos’ investment functions, resulting in the detection of 18 propositional arrays for the ceo's investment functions. in the second phase, q analysis was adopted to typify the ceos’ investment functions, which was based on the subjective cognition of the target population and contributed to the development of the approaches in line with the research objectives. the results confirmed the existence of three mental patterns in the ceos regarding the investment functions in the capital market. considering the concepts and content of propositional arrays, these mental patterns were ‘investment function in stock market indices’ as the first mental pattern, ‘investment function in risk control’ as the second mental pattern, ‘strategic investment function’ as the third mental pattern. the study results revealed different types of investment functions among the ceos’ of stock exchange companies and thus contributed to the development of financial theories from the perspective of ceos’ cognition. in other words, the detection of the investment functions makes the investment decisions about the companies’ stocks in the capital market more secure and the expected return on investment for shareholders and investors more analyzable.
