Perception Studies While stock surveillance will enable you to gauge the success of your meetings with the investment community on both a quantitative and qualitative level (why they bought/sold and how much was bought/sold), the perception study generated by InvestorCom will provide more in-depth qualitative reasoning. Street perceptions - as determined by conversations with buy- side and sell- side analysts - will be delivered in a presentation to senior management (with the actual interview transcripts included as well) helping to design the most effective investor presentations going forward.
