GROWTH OF ALGORITHMIC TRADING IMPACT ON MARKET DATA

Interactive Data is organising a panel discussion

London: 14 February 2005 - ComStock Europe, part of Interactive Data (NYSE: IDC) and a leading provider of real-time global market data, will be holding a panel discussion on the growth of algorithmic trading and its impact on market data on 2 November in London.

Algorithmic trading, whilst not new, is a fast-growing phenomenon in Europe . The rise of hedge funds, combined with the general move towards electronic markets and regulatory pressure for increased transparency and cost efficiency, is contributing to the growth of new trading models. Predictions show that the volume of total algorithmic trading could double in the US through 2006. How will such growth impact the market data industry?

Integration of market data to algorithmic trading applications is vital. And one of the biggest challenges is to manage the rapid growth of data volumes coming from the exchanges and other sources.

Will more datafeeds mean less terminals and therefore less people - or just a change of role? How can multiple datafeeds be managed effectively? And how will the industry cope with such a growth in data needs - more instruments, wider coverage and lower latency?

The panel discussion, which will be chaired by Octavio Marenzi, founder and CEO of Celent, will also look at the market data components relevant to algorithmic trading: the role of real-time pricing, news and static data - not forgetting the data required by the industry to meet new regulations.

The panellists will comprise Gabriella Stern of Dow Jones Newswires, Wendy Morgan of the London Stock Exchange, Eli Lederman of Morgan Stanley, and a leading hedge fund participant.

Those attending will include market data managers, business analysts and consultants, hedge fund players, software and technology vendors, as well as operations and IT managers.
