Why are derivative warrants more expensive than options? An empirical study

Derivative warrants typically have higher prices than do otherwise identical options. Using data from the Hong Kong market during 2002-2007, we show that the price difference reflects the liquidity premium of derivative warrants over options. Newly issued derivative warrants are much more liquid than options with similar terms. As a result, long-term derivative warrants are preferred by traders who trade frequently. In spite of their higher prices, short-term returns on long-term derivative warrants are, in fact, higher than the hypothetical short-term returns on options. The differences in price and liquidity measures decline as the contracts get closer to maturity. Foster School of Business, University of Washington 2011.
