We examine the Taiwanese IPO market for covered warrants, and impact of the warrants’ initiations on underlying stocks’ returns, systematic risk, volatility, and trading volume. The results suggest positive, and statistically significant, price and trading volume effects associated with warrant introductions. The effects are notably different for sub-samples of the first time and subsequently listed warrants. The results of Exponential Generalized Autoregressive Conditional Heteroskedastic model (EGARCH) suggest that covered warrants introduction does not change the conditional distribution of underlying stock returns.

Unlike corporate warrants, covered warrants are not issued by companies on their own stocks, and no new stocks are issued upon exercise.
