This study evaluates the performance of Growth and Value Stock Investment Strategies and investigates the relative performance of these two types of stocks in Denmark and Finland. The research compares the historical returns and consequences of investing in value and growth stocks and examines the factors that drive their performance. The research questions focus on whether there is a significant difference in performance between value stocks portfolios and growth stocks portfolios. The study uses a deductive approach and a quantitative research design to analyze numerical data collected mainly from Thomson Reuters Eikon Datastream. Microsoft Excel and SPSS Statistics were the main tools used to form samples to process and analyze the data. The samples consist of listed stocks on the Danish and Finnish stock markets, and the portfolios are divided based on their Price-to-Book ratios and Price-To-Earnings ratios. The evaluated years are divided into four sub-periods to reflect different economic conditions. The findings suggest that there were significant differences in the performance of value and growth portfolios in the Finnish market during specific sub-periods, while in Denmark, there were no significant differences in returns between portfolios consisting of value stocks and portfolios consisting of growth stocks in all sub-periods, except for sub-period 3. The performance of the portfolios may be affected by factors such as interest rates, financial distress, and economic conditions in various sectors of the economy. The study's results can provide investors with insights into the relative performance of growth and value stocks and help them make informed decisions about stock allocation when forming portfolios, enhancing their investment strategies.
