Which of the following companies focuses on software and systems for trading and financial markets?

The focus of Exegy on software and systems tailored for trading and financial markets makes it the correct choice. Exegy provides advanced market data solutions and trading technology that enable financial institutions to effectively manage complex data flows and execute trades efficiently. Their services cater specifically to the needs of traders and financial professionals, emphasizing low-latency and high-performance requirements crucial in the trading environment.

In contrast, while Oracle, Cisco, and Equinix are significant players in the technology and data management sectors, their primary focuses differ from that of Exegy. Oracle specializes in database management systems and enterprise software solutions, Cisco is known for networking and cybersecurity technologies, and Equinix offers data center services and interconnection solutions. None of these companies are primarily dedicated to the creation of trading-specific software and systems, which delineates Exegy’s niche in the financial technology landscape.
