The results show that higher levels of human capital as captured by total labor expenditures; workforce productivity and human capital management efficiency (i.e., LEI variable) are generally associated with higher abnormal returns. The results are consistent with our research hypotheses according to which firms with higher human capital performance indicators are associated with higher portfolio performance compared to their peers with lower levels of human capital. The portfolio performance results are consistent across both measures (i.e., Treynor’s and Jensen’s) and generally across time (short-term to longer-term returns) with some noticeable convergence in the longer term time horizon (five-year returns).
