TOKYO -- The Tokyo Stock Exchange was the target of criticism Thursday for failing to disclose information and leaving retail investors in the dark after a system failure caused the bourse to shut down an entire day of trading for the first time.
The exchange first detected a hardware malfunction just after 7 a.m., and contacted brokerages at 8:01 a.m. to ask them to refrain from sending orders. But an overall trading halt was not announced to the broader public until about 8:39 a.m., and even then the news appeared only on the TSE website.
