According to CoinMeta, today there was an intensification of selling in AI stocks worldwide, with U.S. semiconductor stocks declining for the sixth consecutive day. This selling signal indicates a significant shift in market sentiment, as rising interest rates threaten an infrastructure spending boom that could be even larger than America's historical railway expansion. South Korean KOSPI stocks fell by 6%, while Japanese Kioxia stocks tumbled 13%. Stocks in the memory and storage sector also saw substantial declines: Western Digital ($WDC) fell 6.5%, Seagate ($STX) fell 6.1%, SK Samsung Electronics (HKEX: 000660) fell 4.8%, Micron ($MU) fell 4.7%, and Sandisk ($SNDK) fell 4.1%. Blackstone Group also downgraded its rating on U.S. stocks to "neutral," warning of the volatility associated with AI. Investors are questioning whether large-scale AI investments can justify their high valuations.
