Why is IREN stock tumbling today?
IREN Ltd shares fell 10.1% to $17.515, nearing their 52-week low, due to Nvidia CEO's resignation, delayed revenue targets, and Microsoft's reduced reliance on third-party neocloud providers. Analysts downgraded the stock, and broader sector pressures added to the decline.
