Purpose: The purpose of this paper is twofold: first, to fill a gap in the intellectual capital (IC) literature by providing insights into the relationship between IC and corporate performance among Arab companies and second, to challenge the validity of the Value Added Intellectual Coefficient (VAIC) as a measure of IC’s contribution to performance.Design/methodology/approach: The research sample included 100 publicly traded Arab companies selected by Forbes Middle East and ranked as top performers in terms of sales, profits, assets, and market value. The methodology included assessing the impact of IC components on company earnings, profitability, efficiency, and market performance for the period between 2011 and 2015. Research hypotheses were tested through the presentation of descriptive statistics, normality tests, correlation matrix, and multiple regression models.Findings: The research yielded ambiguous results. Earnings and profitability were significantly affected by structural and physical capital; efficiency was determined primarily by physical capital; and market performance was mainly influenced by human capital.Research limitations/implications: The main limitation of the research comes from disadvantages of VAIC as the measure of IC’s contributions to performance.Originality/value: The paper fills a void in the study of IC and corporate performance among Arab companies.
This study investigates the performance of Bitcoin as a diversifier under different constraining portfolio optimization frameworks. The study employs different constraining optimization frameworks that seek to maximize risk-adjusted returns (Sharpe ratio) of the portfolio by optimizing allocations to each asset class (asset allocation). The performance attributes are evaluated by comparing the portfolios both with and without Bitcoin under frameworks ranging from equal-weighted, risk-parity, and semi-constrained to unconstrained. This study suggests that Bitcoin, due to its exotic nature, unwavering appeal, and unknown set of drivers, could act as a diversifier in normal market conditions, and it might also have some borderline hedge to safe haven properties. The results further suggest that while Bitcoin may be a potential diversifier for a risk-seeking investor, the risk-averse investor must exercise caution by limiting their exposure to Bitcoin in their portfolios, as unnecessary exposure may increase the probability of losses in extreme market conditions.
