Αξιολόγηση των κινδύνων που συνδέονται με την ψυχολογία των ιδιωτών επενδυτών
In this dissertation, investigated the effect of investor sentiment in their decisions and through them on stock prices. The investigation of the above relationship was based on relevant data from the OECD (Organization for Economic Cooperation and Development) consisting mainly of indicators, which are used as proxies to the investment psychology on a period 2008-2010. After the investigation has shown that the prices of shares of new companies formed randomly in time, and do not follow the path of a particular index or a combination of indices. On the other hand, the prices of old business formed by combining the following indicators. The results of the empirical analysis showed that there are variables that affect both old and new business stock prices. Specifically, the consumer confidence index and the index of business activity affect the prices of older business rather than stock prices of the new business. Instead of the previous conclusions, neither inflation nor consumer price index affect the prices of shares in any of the two groups.
