Explained: Why Samsung shares tanked 8% while rival SK Hynix traded higher on Monday

Samsung Electronics shares fell 8% after its record $79 billion shareholder-return plan disappointed investors. The company plans to return 90 trillion won to 110 trillion won this year, including 30 trillion won in Q3 cash dividends. While the payout is five times its 2020 record, analysts said it fell short of expectations and lacked clarity on buybacks.
