Fujitsu Ltd, the developer of the Tokyo Stock Exchange's trading system, is still investigating causes of the bourse's worse-ever outage last week, the company's chief executive said on Monday, Trend reports citing Reuters.
“We will make utmost efforts to find the causes and prevent recurrences of such troubles,” Takahito Tokita said at a briefing on Fujitsu’s digital strategy, in his first public appearance since the TSE outage paralysed the world’s third-largest equity market.
The TSE has said the glitch was the result of a hardware problem at its “Arrowhead” trading system, and a subsequent failure to switch to a back-up. It caused the first full-day suspension since the exchange switched to all-electronic trading in 1999.
