Abstract：
Derivative warrants typically have prices higher than those otherwise identical options.
Using data from the Hong Kong market during 2002-2006, we show that this
di_erence reects the liquidity premium of derivative warrants over options. Newly
issued derivative warrants are much more liquid than options of similar terms. As a
result, longer-term derivative warrants are preferred by traders who trade frequently.
In spite of higher prices, short-term returns on longer-term derivative warrants are, in
fact, slightly higher than the hypothetical short-term returns on options. On the other
hand, derivative warrants near expiration are less liquid, more thinly traded, and no
more expensive than options of similar terms.
