The growing significance of sustainability in business practices has led many companies to explore green marketing initiatives, including the use of social media to promote environmentally friendly products and practices. However, the adoption of green social media marketing (G-SMM) by Small and Medium Enterprises (SMEs) remains underexplored. This study investigates SME perceptions of G-SMM and explores the benefits, challenges, and adoption levels associated with incorporating green marketing strategies into their social media presence. The research, which uses a combination of quantitative and qualitative methods, provides valuable insights into how SMEs perceive G-SMM and the factors that influence their decision to adopt or avoid it. Findings indicate that while SMEs are generally aware of green marketing, many face barriers such as cost, lack of expertise, and concerns about its effectiveness in engaging consumers.

As traditional stock valuation methods struggle with the complexity of modern financial markets, new frameworks are required. This paper presents the RANKS multi-factor rating model, a systematic tool for identifying undervalued public companies. The methodology is based on a hybrid "quantamental" approach, blending the depth of fundamental analysis with the discipline of quantitative algorithms. The model's architecture consists of seven blocks that evaluate over 150 financial, market, and corporate metrics across a universe of 55,000 global companies. A key distinction is its integration of non-traditional data, including operational and human capital indicators, for a more comprehensive assessment. Case studies are analyzed to evaluate the model's empirical effectiveness in generating alpha, positioning it as apractical implementation of advanced active investment strategies.
