Exchange Regulation ("JPX-R") and Tokyo Stock Exchange, Inc.
("TSE") decided to apply artificial intelligence (AI) to market
surveillance operations to detect such misconduct as market manipulation.
Deployment of AI to market surveillance operations will commence today.
In surveillance operations of the TSE market for monitoring and preventing
unfair trading, a broad range of orders that are likely to involve unfair
trading are first identified by surveillance systems based on certain criteria.
Surveillance personnel then conduct preliminary investigations to analyze the
trading situation surrounding such orders.
these preliminary investigations, surveillance personnel determine the
possibility of unfair trading before conducting detailed investigations and
report to the Securities Exchange Surveillance Commission.
JPX-R and TSE will be deploying two AI technologies: NEC Corporation’s
"NEC Advanced Analytics - RAPID machine learning" and Hitachi, Ltd.’s
"Hitachi AI Technology/H". These technologies have been supplied with
a store of knowledge previously used in operations by surveillance personnel to
evaluate irregularities in trade activity for preliminary investigations.
The deployed AI technology enables surveillance personnel to finish preliminary
investigations more quickly and focus on detailed investigations. While the
final decision on conducting such investigations will continue to be made by
surveillance personnel, this initiative facilitates even more in-depth and
detailed investigations and is expected to improve their market monitoring
functions, thereby protecting the fairness and credibility of the TSE market.
Japan Exchange Group, Inc. remains committed to offering better markets by
proactively utilizing AI alongside other new technologies.
