Seoul-listed Samsung slumped 12.39% to KRW 14,500 each on Friday after EToday claimed its operating deficit for the quarter would run to KRW 1 trillion ($874m).
Rivals were caught up in the sell-down, which came just a few days after DSME took a beating amid claims it is facing its own heavy deficit.
Hyundai Heavy Industries and DSME also saw their stocks reverse today.
“The recent news flow, following Daewoo Ship’s operating loss reports, is souring investor sentiment across the heavy industry,” John Yu, an analyst at NH Investment & Securities, told Bloomberg.
Samsung poured cold water of the figures being reported, telling investors it has not finished collating its accounts for the three months to the end of June.
