The cancellation of trading between 5 pm and 5:30 pm means that "it can get messy for the back-office to sort out tomorrow", notes Ålandsbanken's stock exchange manager Lars Söderfjell in Di. He points out that many trades are made during the last half hour of the stock exchange's opening hours.
The technical glitch resulted in wild price fluctuations in the closing trade. Among other things, it seemed as if the share in the medical technology company Asker Healthcare soared almost 30 percent and that the steel giant SSAB plummeted over 27 percent.
Work is underway to resolve the issue and we expect to open as usual tomorrow, says a spokesperson for the stock exchange operator Nasdaq Nordic to the news agency Bloomberg.
