Micron and SK Hynix ADR (ticker: SKHY) surged over 10% in overnight trading, with Micron gaining 12.17% and SKHY rising 13.75% intraday. Wall Street analysts attributed the rally to hedge fund position liquidation in semiconductor and AI stocks reaching completion, triggering short covering and bargain hunting. The rebound occurred despite oil prices rising 2% on Houthi maritime blockade warnings and US Treasury yields climbing—conditions typically unfavorable for growth stocks.
US Stock Indices Advance Amid Geopolitical Tensions
US stock indices rose across the board in overnight trading, with the Dow Jones Industrial Average gaining 0.74%, the S&P 500 advancing 0.89%, and the Nasdaq Composite climbing 1.29%. Most of the S&P 500's 11 sectors posted gains, excluding communication services (heavily weighted toward Google and Meta) and defensive sectors. Oil prices increased approximately 2% after Yemen's Houthi rebels issued maritime blockade warnings and two tankers reportedly turned back in the Red Sea. US Treasury yields rose across both long-term and short-term maturities as geopolitical uncertainties intensified.
Semiconductor Stocks Rally on Position Unwinding
Semiconductor stocks posted sharp gains despite the unfavorable macro backdrop. Micron climbed 12.17%, SanDisk surged 14.27%, and SK Hynix's US ADR extended gains in after-hours trading following its 13.75% intraday advance. Wall Street trading desks noted that the rally was not driven by specific news released on the day, despite upcoming events such as AMD's conference "AMD Advancing AI" starting on the 22nd and Google's earnings announcement.
Wall Street Cites Historic Selloff Completion as Rebound Catalyst
UBS trading desk highlighted that momentum stock declines are entering final stages and cited opportunities for scaled buying in semiconductor stocks. Wall Street hedge funds reduced long positions in momentum stocks including semiconductors and AI to approximately 5% of total market capitalization, representing the largest selloff on record by scale. With positions significantly lightened and selling pressure exhausted, bargain hunting and short covering combined to drive rapid price rebounds. The pattern resembles market dynamics following the DeepSeek shock, where Chinese AI developments triggered short-term position adjustments followed by recovery.
Google Earnings and AMD Conference Set as Key Semiconductor Sentiment Tests
Google's earnings announcement is positioned as a critical inflection point for reinforcing Wall Street's belief that recent semiconductor stock declines stem from technical factors rather than fundamental deterioration. Investors will scrutinize whether AI investment continues to expand and whether companies can demonstrate profitability alongside increased spending. Consensus estimates for Google's parent company Alphabet project quarterly revenue of $117 billion and earnings per share of $2.88. AMD's conference "AMD Advancing AI" begins on the 22nd.
