Pre-Market Caution Ahead of CPI Data Drags Down US Stocks, S&P 500 Holds Ultra-Tight Range, Storage Sector Strengthens Against the Trend, SK Hynix Surges Over 4%

August 12th, according to BIT (bit.com) market data. Ahead of today's CPI data release, the market remained cautious, with all three major U.S. stock indexes closing in the red. The Nasdaq fell by 0.6%, the Dow Jones fell by 0.34%, and the S&P 500 fell by 0.32%. The S&P 500 has maintained an extremely narrow intraday trading range for the fourth consecutive trading day, presenting a "calm market, price oscillation" scenario. Large-cap tech stocks weakened for the second consecutive day, with the seven tech giants dragging down the indexes. The Nasdaq 100 Index closed hovering above the 50-day moving average.

Within the AI sector, there was a clear internal differentiation. Software infrastructure and optical networking saw sector rotation, while AI semiconductor stocks saw a slight increase, but the gains fell short of the market's expectations for the $500 billion financing framework. Previously, Nvidia teamed up with six Wall Street financial giants including Blackstone and Goldman Sachs to establish a $500 billion financing platform for AI infrastructure development. The news failed to impress the market and instead triggered concerns about "circular financing." Google fell by 3.84%, marking its largest single-day decline in nearly six months. Oracle dropped by 3.71%, Cloudflare by 1.20%, and Amazon by 2.09%.

The U.S. stock storage sector saw gains, with SK Hynix surging over 4%, SanDisk and Seagate Technology up over 2%, and Micron up by 0.87%.
