演講主題:

(1) Stock Price Crashes and Equity Lending Market Conditions: Evidence from Lending Fees and Fee Risk

(2) Does Short-selling Threat Discipline Managers in Mergers and Acquisitions Decisions?

講題摘要:

(1)

  We find that stock price crash risk is positively related to lagged equity lending fee and fee risk. This relation is stronger for stocks with larger prior returns, consistent with bubble-like crashes due to poor lending market conditions. We also find stronger results for the stocks with lower absolute earnings surprises, lower short interests, and higher information uncertainty. Our findings are robust to alternative measures of crash risk and lending market conditions. Last, the results hold when adopting a difference-in-differences methodology based on the Reg-SHO Pilot Program and a fuzzy regression-discontinuity design based on Russell Index reconstitution, mitigating endogeneity concerns.

(2)

  We explore the disciplining effect of short-selling threat, proxied by the value of shares available for short sellers to borrow, on merger and acquisition (M&A) decisions. Our results indicate that acquiring firms with more stock lending supply have higher announcement returns. We also find a stronger disciplining effect when managers’ personal wealth is more linked to the stock price and when the firm is more likely to be the target of a hostile takeover. To rule out alternative explanations and mitigate endogeneity concerns, we adopt two instrumental variable approaches and find similar results. Consistent with our argument, the difference-in-difference analysis shows that the disciplining effect is stronger for firms with fewer short-sale constraints. In addition, the disciplinary effect exists only for non-financial-constrained firms and non-all-cash M&A deals, and we find that the short-selling threat improves firm value and profitability in general.
