As already mentioned there is an abundance of studies showing that mechanical strategies of investing in value stocks outperform the market. These studies contradict the Efficient Market Hypothesis, which in turn is a necessity in order to support an active investment approach of value investing. Also, some studies that do go further in order to investigate how to improve the value premium use financial analysis based on historical data in their research (e.g. Piotroski [2000]). On the other hand the financial analysis in these studies is not based on the fundamentals of value investing as taught by for example Benjamin Graham and Bruce Greenwald and could be considered as somewhat arbitrary. Consequently, even though these studies show how one could improve the value premium further by not only sorting stocks based on their market-to-book ratio, but other financial ratios as well, they do not provide empirical input on the more practical perspective of the value investing approach as practiced by investors around the world. By applying Greenwald’s valuation model our study is better supported by a widely recognized theoretical framework, i.e. value investing as it is thought by Benjamin Graham and used by value investors today.
