    Abstract

    A good insight in the economic market leads to a favorable position from which we can maximize the profits of our investments. Is it possible to make such investments with regards only to the size of the companies we are considering? Numerous studies have been made on the small firm effect as an anomaly of the capital market. The effect supposedly tells us that, given the same period of time, small companies generates a higher percentage return than large companies. This contradicts the Efficient-market hypothesis, and the purpose of this research is to analyze whether this could be true, or not. The research study is made with regards to micro-size companies in the Swedish capital market during the years 2005-2014, thus, this is an extreme version of the small firm effect. A quantitative statistical analysis is used to measure the average return of three different stock portfolios; Large Cap, Small Cap and Aktietorget. Three different hypothesis are tested and the results analyzed with the help of statistical T-tests in SPSS are used. The results of the study is that there is no solid statistical proof that there is a difference in profit between the three different markets during the time period. Nor could an effect be seen during any smaller time period within the given time frame.
