Customers of MERITZ Securities experienced difficulties in investing in U.S. stocks for about an hour due to a computer failure in the home and mobile trading system (HTS·MTS).

According to the financial investment industry on the 7th, a problem occurred where buy and sell orders were not processed properly for about 1 hour and 10 minutes after the regular U.S. market opened at 10:30 p.m. the previous night on the MERITZ Securities HTS·MTS.

MERITZ Securities stated that after recovering from the system failure, they announced that "current orders for U.S. stocks are being processed normally," and "we deeply apologize for any inconvenience caused, and related compensation measures will be promptly communicated."

MERITZ Securities is investigating the exact cause of the system failure. They also plan to prepare specific compensation measures.

However, as the system failures at MERITZ Securities have been recurring, some customers are expressing dissatisfaction. Examples include errors in U.S. stock orders in December last year, errors in calculating merger ratios for U.S. stocks in February this year, and errors in application orders in April this year.

Since November last year, MERITZ Securities has been running an event where transactions involving domestic and U.S. stocks and dollar exchanges can be conducted free of charge without commission through the Super365 account. This is part of a strategy to expand their retail business.
