This paper examines diversification as a source of value creation and destruction in private equity (PE) funds. Previous literature has focused on the “diversification discount” in corporations. However, in PE funds, diversification might increase returns by ameliorating managerial risk aversion and facilitating knowledge sharing. I examine a sample of 1,505 PE funds and show that industry and geographic diversification can increasePE fund returns. This is likely due to knowledge sharing and learning, not merely risk reduction. Diversification can reduce returns if it spreads staff too thinly across industries or is motivated by risk aversion rather than performance bonuses.

This study highlights the link between stock return volatility, operating performance, and stock returns. Prior studies suggest that there is a ‘low volatility’ anomaly, where firms with a low stock return volatility out-perform firms with a high stock return volatility. This paper confirms that low volatility stocks earn higher returns than high volatility stocks in emerging markets and developed markets outside of North America. We also show that low volatility stocks have higher operating returns and this might explain why low volatility stocks earn higher stock returns. These results provide a partial explanation for the ‘low volatility effect’ that is independent from the existence of market anomalies or per se inefficiencies that might otherwise drive a low volatility effect. We emphasize the importance of controlling for stock return volatility when analyzing operating performance and stock performance.

This paper analyzes the role of foreign VCs in driving venture success in emerging markets. We analyze a comprehensive data set of 4753 portfolio companies from China. We test whether the presence of a foreign VC increases the likelihood that a portfolio company is successfully exited. We find that the presence of a foreign VC does not per se significantly increase the likelihood of a successful exit. However, the likelihood of a successful exit increases if the foreign VC collaborates with a joint venture (JV) partner. Further, the impact of foreign VC backing depends on the nature of the VC, with foreign VCs tending to perform better when investing in late-stage companies and when they are diversified across industries. If a foreign VC successfully exits an investment, then, compared with a domestic-VC, it prefers to exit via a M&A or secondary-buyout than via an IPO, reflecting the significant lock-up periods associated with VC-backed IPOs in China, the difficulty of achieving a foreign listing, and the difficulty listing a start-up on Chinese markets.
