AbstractThis study examines if informed trading is present in the index option
market by analyzing the KOSPI 200 options, the most actively traded derivative
product in the world. The spread decomposition model developed by Madhavan,
Richardson, and Roomans (1997) is utilized and the adverse‐selection cost
component of the spread estimated by the model is then used as a proxy for the
degree of inf... hiện toàn bộ
This paper examines whether structural breaks contain incremental information
for forecasting the volatility of copper futures. Considering structural breaks
in volatility, we develop four heterogeneous autoregressive (HAR) models based
on classical or latest HAR‐type models. Subsequently, we apply these models to
forecast volatility in the copper futures market. The empirical results reveal
that ... hiện toàn bộ
AbstractThis study investigates the relative performance of various historical
volatility estimators that incorporate daily trading range: M. Parkinson (1980),
M. Garman and M. Klass (1980), L. C. G. Rogers and S. E. Satchell (1991), and D.
Yang and Q. Zhang (2000). It is found that the range estimators all perform very
well when an asset price follows a continuous geometric Brownian motion.

AbstractIn this article we investigate the statistical properties of wholesale
electricity spot and futures prices traded on the New York Mercantile Exchange
for delivery at the California–Oregon Border. Using daily data for the years
1998 and 1999, we find that many of the characteristics of the electricity
market can be viewed to be broadly consistent with efficient markets. The
futures risk pre... hiện toàn bộ
AbstractIn the framework of encompassing regressions, the information content of
the jump/continuous components of historical volatility is assessed when implied
volatility is included as an additional regressor. The authors' empirical
application focuses on daily and intradaily data for the S&P100 and S&P500
indexes, and daily data for the associated VXO and VIX implied volatility
indexes. The re... hiện toàn bộ
AbstractThis paper focuses on the increasing competition between exchanges for
listing similar index futures contracts and the impact this has on information
dissemination between various markets. Specifically, using both the Hasbrouck
and Gonzalo–Granger methodologies for extracting the information content held in
each market, a comparison of information efficiencies between the Singapore
