In Sweden most people are keeping their savings in ordinary saving account without any interest return. In this study two investment strategies have been examined; Graham Screener and Net Nets strategy. Investigating which of these performs better on the different Swedish stock markets. The subgroups that have been investigated are Large Cap, Mid Cap and Small Cap. The focus of this study is to find out which strategy yields the highest return with risk taken into consideration. After testing the strategies over a 15-year time period the study concluded that the Graham Screener strategy is to prefer over Net Nets strategy. The results also gave a hint that the market efficiency theory could be questioned according to the calculations in this study.

This study shows how the two investment strategies Net-nets and magic formula performs on the Swedish stock markets subgroups Small, Mid and Large Cap. Also, with the intention to see which of these two strategies suits the private investors on the Swedish stock market and see which gave the highest rate of return. The results after a 15-year long time period showed us that Magic Formula was the one to be preferred on the Swedish stock market much due to the incompatibility of Net-nets on the Swedish stock market. Mainly because of the small sample of compatibility companies that suited the Net-nets instructions. Magic Formula was therefore able to yield a higher rate of return on all the subgroups compared to Net-nets and gave us the conclusion that it performs best on the Mid Cap on the Swedish stock market.

This study examines the Swedish Stock Exchange during the time period of 1998-2016. Where the purpose is to investigate and compare five different investment strategies to see if these investment strategies can create excess return on their investments, after adjustment for risk. The investment strategies can be found on the internet, and be used after purchasing a smaller amount of money, therefore the results can be applied to all investors independent on their level of experience. The results for the different investment strategies are not clear, the different tests give mixed results which leaves four of five hypotheses unanswered. However, there is one strategy that can be rejected, it cannot beat the market, which is the Net-Nets strategy. In general, one could thus say that the investment strategies can create higher return compared to the market, but that these returns are random. Therefore, it requires a longer time period for the investor as well as higher risk, since one never knows when this large return will be given.
