This study proposes chief executive officer (CEO) overconfidence to be an alternative explanation to corporate cash holdings. We find positive effects of CEO overconfidence on the level of cash holdings and the value of cash, which are mainly due to the investment environments faced by firms. The positive effects of CEO overconfidence on cash holdings level and cash value are barely affected by the traditional motives of cash holdings based on trade-off and agency theories. The analysis of cash sources further explains why firms with overconfident CEOs can aggressively pursue risky investments and maintain large cash holdings at the same time. Although the prior literature indicates that overconfident CEOs tend to avoid equity issues for their capital investments, the contribution to cash savings from equity is higher than that from debt. Additional robustness tests also support our empirical findings.

In this paper, we propose a new spot-futures hedging method that determines the optimal hedge ratio by minimizing the riskiness of hedged portfolio returns, where the riskiness is measured by the index of Aumann and Serrano (2008). Unlike the risk measurements widely used in the literature, the riskiness index employed in our method satisfies monotonicity with respect to stochastic dominance. We also provide an empirical example to demonstrate how to estimate and test this optimal hedge ratio in equity data by the method-of-moments.

This study investigates the relation between IPO underwriting and subsequent lending. We find that when a bank underwrites a firm’s IPO, the bank is more likely to provide the issuer with future loans at a lower cost, compared to banks without an IPO underwriting relationship. The evidence also suggests that the underwriting banks share information surplus with the IPO firms in the post-IPO loans, supporting the cost-saving hypothesis. Overall, the evidence for the relation between prior IPO underwriting and subsequent lending supports the notion that firms can derive value from investment bank relationships.

We examine whether investors can improve their investment opportunity sets through the addition of volatility-related assets into various groupings of benchmark portfolios. By first analyzing the weekly returns of three VIX-related assets over the period 1996–2008 and then applying mean–variance spanning tests, we find that adding VIX-related assets does lead to a statistically significant enlargement of the investment opportunity set for investors. Our empirical findings are robust and have two implications. First, there is scope for the further development of financial products relating to volatility indexes. Second, hedge fund managers can utilize VIX futures contracts or VIX-squared portfolios to enhance their equity portfolio performance, as measured by the Sharpe ratio.

This study explores the influence of chief executive officer (CEO) overconfidence on acquirer bondholder wealth in mergers from 1994 to 2019. We find that CEO overconfidence benefits acquirer bondholders. Overconfident CEOs are likely to choose targets with lower return correlations rather than targets with lower risk than acquirers. We further show there is a positive wealth effect during announcement periods as well as firm risk reduction and a positive long-run bond market reaction subsequent to merger completion when overconfident acquirers merge with targets that are less correlated. Overall, the coinsurance effect dominates the liquidity effect on overconfident acquirer bondholder wealth during a merger.

Using index and financial exchange-traded funds (ETFs), this study explores the relation between funding liquidity and equity liquidity during the subprime crisis period. Our empirical results show that a higher degree of funding illiquidity leads to an increase in bid–ask spread and a reduction in both market depth and net buying imbalance. Such findings indicate that an increase in funding liquidity can improve equity liquidity, with a stronger effect for the financial ETFs than for the index ETFs. Our study provides a better overall understanding of the effect of the liquidity–supplier funding constraint during the subprime crisis period.
