This article examines the
pattern of information flow between the percentage price change and
the trading volume in gold futures contracts using daily data over a
ten-year period. We employ the robust two-step procedure proposed by
Cheung and Ng (1996) to detect the causality in variance. We find
evidence of strong contemporaneous causality that is indicative of
the mixture of distribution hypothesis of information flow. We also
detect, although not as strong, lagged causality running from
percentage price change to trading volume. This indicates mild
support for sequential information flow as well directed from price
change to trading volume. This is contrary to the documented
behavior in agricultural futures and crude oil futures, where
bi-directional causality has been reported. We hypothesize that this
is probably due to the special nature of gold as a commodity and the
fact that the gold market takes on added importance when the equity
market underperforms. |
