CNBC's Jim Cramer warned Thursday that the semiconductor sector has morphed into a "casino of emotions," pointing out that "insanely good TSMC numbers mean nothing" to a market suddenly fixated on the massive U.S. market debut of South Korean memory giant SK Hynix.

His comments followed a surprising drop in Taiwan Semiconductor Manufacturing Co.

Ltd.

(NYSE:TSM) stock despite a blockbuster earnings report.

The SK Hynix 'Casino' Effect According to Cramer, the irrational downward pressure on TSMC is deeply tied to the broader emotional volatility reshaping the chip sector following the U.S. listing of SK Hynix.
