The average spread (difference between buy and sell prices) for Dutch shares narrowed by between 19% and 40%, leading immediately to lower costs for all investors. Mid-caps and small caps traded with a liquidity provider had significantly tighter spreads than shares traded without liquidity providers.
This information was revealed during an initial analysis conducted by Euronext following the introduction of Euronext's cross-border trading system at the Amsterdam market in October 2001, when the exchanges of Amsterdam, Brussels and Paris were united on a single trading platform based on NSC technology.
Investors and traders are expected to reap the full benefits of the new system after Euronext's clearing and settlement systems are also integrated.
