The effects of status on the performance of portfolio diversification strategies

摘要

Purpose - This paper investigates how a firm's status moderates the performance of its investment portfolio diversification strategy. We combine the investment diversification literature with the organizational status theory, arguing that status would weaken the benefits of a specialist strategy in their niche industry of investments while strengthening the positive consequences of a generalist strategy across various industries. Design/methodology/approach - We collected our data using the Securities Data Company (SDC) Platinum VentureXpert database. A fixed-effects spline regression analysis for 2,201 US venture capital firms between 1969 and 2016 was used to test for a nonlinear relationship between the level of portfolio diversification and firm performance. Findings - We found that status differences exist in the performance of a specialist strategy but not in that of a generalist strategy. Our results indicate that portfolio specialization in fewer number of industries has little impact on low-status firms, whereas high-status firms suffer significantly lower IPO success rates. In contrast, above-median portfolio diversification was found to be beneficial to both high- and low-status firms. Originality/value - We specifically identify the impact of status on the performance of investment diversification strategies, an area of research which has received little attention. Further, our findings provide some practical implications for managers making investment decisions between specialist and generalist investment strategies, given their status within the market. Implications for understanding the roles of firm status in portfolio diversification strategies are discussed.
