This postgraduate thesis is focusing on the returns of growth and value stocks for the 11-year period 2013-2023, during which the Greek stock market faced significant national and global economic challenges. By conducting inivariate portfolio analysis and multiple regression analysis with the application of fixed-effects models, the question of whether value investments can indeed generate excess returns compared to growth investments is addressed.
As control variables of the analysis models, the price-to-sales per share (P/S), the price-to-earnings per share (P/E), the price-to-book value per share (P/B), the price-to-cash flow per share (P/CF), the dividend yield (DY) and market capitalization of the companies (Market value) are used. Four out of the six ratios showed positive but marginal outperformance, with the only exception being the Dividend Yield, which showed a positive outperformance of +7.34%, with statistical significance of 10%. This development can be explained by the international contraction of value premiums, which has been particularly pronounced since the global financial crisis. Interestingly, only the negative P/CF ratio showed negative statistical significance at the 10% level.
In the multiple regression analysis, the results obtained highlight the P/S and P/E ratios as statistically significant. These results have, in general, some common points with the results of Kyriazis and Christou (2013), who had conducted a similar analysis for the Greek stock market in the past. Based on the results of this study, we conclude that investing in value portfolios in the Greek Stock Exchange does not confirm the generation of excess returns.
