Stock Crash: SK Hynix plunges 57% from peak in four months, loses nearly $700 billion in value

Investors should watch for upcoming earnings reports and broader trends in global semiconductor demand. A recovery in the AI sector or signs of stabilizing memory chip prices could influence the stock's next major move.
