The Philadelphia Semiconductor Index fell for an eighth consecutive trading day, its longest losing streak since 2008. Memory stocks bore the brunt: SanDisk, Western Digital, and SK Hynix ADRs each dropped more than 6% in a day, while Micron fell 5.6%. In eight trading days, the sector lost nearly $2 trillion in market value. Several financial media outlets pointed to three factors: growing concern over high-yield debt financing at CoreWeave, a more than 3% one-day jump in international oil prices that lifted inflation expectations, and slower-than-expected revenue growth at AI giants.
More interesting was how trading extended into the weekend. Binance’s USDT-margined perpetual stock contracts trade 24/7 and track the corresponding share prices, so sentiment continued to play out on Saturday: the semiconductor inverse ETF contract $SOXS rose 2.3% in a day, with about 120 million U in trading volume—the highest of all stock contracts. The memory-sector contract $WDC was down around 2.4%, extending the weakness seen in U.S. stocks on Friday. Binance’s largest single liquidation in the past 24 hours happened to be a short position in the SOXS contract, worth about 7.3 million U—both bulls and bears had put big money on the line.
My take: The surge in volume for inverse contracts looks more like hedgers using the weekend window to insure their AI hardware exposure than confirmation of a trend reversal. Oil prices are a new variable this time around; if they keep rising, rate expectations could in turn weigh on high-valuation sectors. One reminder: inverse ETF contracts like $SOXS come with threefold leverage, which magnifies volatility by the same factor, so it’s best to keep positions small.
