Investors looked beyond the bleak outlook to welcome the aggressive investment cut, sending SK Hynix shares 1.7% higher in a bet the scale of the action would help control chip oversupply and prop up chip prices. SK Hynix said its operating profit fell to 1.66 trillion won ($1.16 billion) in the July-September quarter, from 4.2 trillion won a year earlier. The result was below analysts' expectations of a 1.87 trillion won profit, according to Refinitiv SmartEstimate. SK Hynix said its 2022 investment is expected to be at the "upper range of 10-20 trillion won ($7-14 billion)", meaning 2023 investments could fall below 10 trillion won. SK Hynix also warned of uncertainties involving its chip plants in China due to U.S. export restrictions on advanced chip equipment to China aimed at slowing Beijing's technological advances.
