Stronger won to test chip, display firms' Q3 profitability

The strengthening Korean won is reducing third-quarter earnings estimates for major electronics firms like Samsung Electronics and SK hynix, as their dollar-denominated revenues shrink when converted to won. Brokerages have cut profit forecasts, with Samsung's consensus operating profit dropping 9% and SK hynix's falling 6.7% in recent weeks. Both companies have warned of significant profit reductions due to exchange rate fluctuations.
