Nasdaq’s Technology Floor: Its President Takes Stock

On-line trading technology evolves at the first stock market to be based on a computer network of display screens

Nasdaq’s Technology Floor: Its President Takes Stock

Over the years, electronics technology has revolutionized virtually every securities market, most notably The Nasdaq Stock Market Inc. Nasdaq, a trademarked name, was the world's first market to handle trading not on an exchange floor but through a computer network linking display screens. But since its advent in 1971, changes in telecommunications and computer technologies have been ongoing, profound, and complex.

As a screen-based market, Nasdaq (which originally stood for National Association of Securities Dealers' Automated Quotations) has striven to stay on top of those developments. It is in the process of completing a US $180 million systems migration program--the largest single telecommunications and computer project undertaken by a U.S. stock market. The effort has involved replacing the entire Nasdaq system with a standards-based, client-server network, while moving from analog to digital network technology and upgrading the core systems to process 500 transactions a second--a rate that enables the market to handle at least a billion shares a day. With these systems, Nasdaq has the flexibility to constantly improve operational efficiency and regulatory oversight.

For more than a century, IEEE has been honoring technology pioneers with its Medal of Honor. The organization’s most prestigious award, it is given to engineers who have made exceptional contributions to or had an extraordinary career in electronics, electrical sciences, and engineering.

To celebrate the award’s long history, IEEE recently released a commemorative ebook, Over 100 Years of the IEEE Medal of Honor. The volume chronicles the innovators who have received the award since its establishment in 1917. The Medal of Honor has been awarded annually since its establishment except in 1925, 1947, 1965, and 1976.

The modern internet-connected world is often described as wired, but most core network data traffic is actually carried by optical fiber — not electric wires. Despite this, existing infrastructure still relies on many electrical signal processing components embedded inside fiber optic networks. Replacing these components with photonic devices could boost network speed, capacity, and reliability. To help realize the potential of this emerging technology, a multinational team at the Swiss Federal Institute of Technology Lausanne (EPFL) has developed a prototype of a silicon photonic phase shifter, a device that could become an essential building block for the next generation of optical fiber data networks.
