Shares in Seiko Group Corporation fell 11.70% on Wednesday after an earnings report triggered a stop-low trigger, local media reported. The drop came despite the company issuing an upward revision to its profit plan, which noted that the second half of the fiscal year would account for half of the total outlook.
Earnings revision failed to reassure
The stock price of watchmaker Seiko Group (8050) fell 11.0% on November 11, according to a note.com report. During trading hours, the shares dropped to the stop-low level on the Tokyo Stock Exchange. The decline occurred even though the company had revised its profit forecast upwards in its latest earnings report.
The earnings report stated that the second half of the fiscal year would be half of the total profit plan. This detail appeared in the source material as a key point of the company's guidance, yet it did not prevent the sharp sell-off.
