Daiwa Securities SMBC has become the third securities firm in two months to make a trading error on the Tokyo Stock Exchange, suffering losses of about ¥300m (€2.2m) from wrongly-inputted information.

Daiwa SMBC, a joint venture between Daiwa Securities Group and Sumitomo Mitsui Financial Group, offered 25,000 shares in Sumitomo after an employee wrote the wrong ticker and company name on an order.
