Privata småsparares påverkan på Aktieprisvolatilitet

: En empirisk studie av smallcap-bolag

Abstract

In the following study both financial and ownership data have been gathered regarding companies listed on the Swedish OMX Stockholm Small-cap list to determine whether the fraction of small private investors have an significant impact on volatility. The reason is because volatility has a central role within the stock market making it an important variable. Previous theories suggest that a number of different variables that affect the volatility, where small private investors are one of them. Our regression model proves that the fraction of small private investors indeed have a significant effect on volatility. Our results also suggest that the company’s earnings divided by its total assets is a variable which alters the volatility. Multiple variables which were suggested by theories to have an impact on volatility could not be proven to be true, one of these variables were institutional owners.
