The increasing growth of soccer economy is delivering new challenges for prospective investors in terms of stock price volatility. Such challenges are rooted in behavioral finance and efficient market hypotheses. Given this, the aim of our paper is to test the link between sport performance and correspondent stock price for the Italian listed football clubs (Juventus, Lazio, AS Roma). Our results suggest that soccer wins are likely to have a positive impact over stock price. This impact is more pronounced for local stocks and thus the findings have policy implications for emotional investors.

Introduction: In basketball, ball possession can begin and end in many different ways, for example, ball possession may begin with an out-of-bounds, a stolen ball, a rebound etc, and may also end with a throw, a turnover or when the attack time has expired.Aim: Starting from the working hypothesis that the backboard rebounds represent an important factor in gaining ball possession, we have proposed to identify and analyze the game parameters recorded in the national basketball leagues.Material and methods: The theoretical documentation included explaining, based on specialized literature, terms related to ball possession. Also, in order to accomplish the purposes of this research, we have used statistical analysis (possession, arithmetic mean, amplitude) and graphical representation. This study focused on all teams participating in the 2019-2020 season of the National Basketball Leagues (16 men’s and 13 women’s teams).Results: Following the analysis and centralization of the game parameters from the 146 games played in the men’s league and 144 games in the women’s league, we have identified the main ways of gaining ball possession.Conclusions: Backboard rebounds represent the main way of gaining ball possession (which confirms the hypothesis).

Starting from Michael Porter's diagnosis regarding the dynamics of the competitive environment based on five forces and from the perspective of the value chain analysis in achieving the competitive advantage on a cutting edge market, this article proposes an in-depth analysis in the topic of purchasing decisions within economic organizations, whose processes need to be approached strategically in order for organizations to develop and evolve properly. Managing in a proper way the relation with the suppliers of goods, raw materials, and services will determine the costs to decrease and thus the revenues and implicitly the profit will grow, placing the entity on a good track in fighting with competition and bringing benefits for all its stakeholders. Moreover, taking into account that the environment in which organizations operate is often surrounded by uncertainty, the decisional process, especially the strategic one, is characterized by ambiguity, doubled also by the subjectivity of the human factor in decisional reasoning. In this context, choosing the right supplier according to specific selection criteria represents the most important decision of the purchasing function. Sometimes, it requests the implementation of qualitative mathematical methods such fuzzy logic, which is a powerful tool that can efficiently shape the ambiguity within decision-making process and support the organization long-term strategy and competitive market positioning.
