Some models hinged on the implicit assumption that potential stakeholders look to a company's stock price as an indicator of how profitable it would be for them to make a non-stock investment in the company.Do you think this is rational?If people know that noise traders exist, should that make a difference for the type of information they ascribe to the stock price?Secondly, should corporate CEOsreallycare about the possibility that short-term stock price fluctuations might have long-term impacts on their companies?Or do you think it is more likely that CEOs care about stock price primarily because their own evaluation and compensation depends on it, and not because of any negative impacts it has on the company as a whole?
