Results present significant positive abnormal returns and trading volumes before the announcement of a warrant's issuance, and the effect is stronger when the hedging demand is larger. Moreover, a significantly positive relationship exists between stock return volatility and the price elasticity of hedging demand. Finally, we observe a significantly negative price effect upon the underlying stock after a call warrant has expired in-the-money due to the liquidation of hedging portfolios. ? 2014 Elsevier B.V. |
