The SPDR Portfolio S&P 500 ETF (SPLG) closed up 0.85% at $71.12 on January 28, 2025, as the S&P 500 Index rose 0.92% to 6067.70, driven by a rebound in technology stocks. The recovery followed a sharp sell-off on Monday, triggered by concerns over a new AI model from Chinese startup DeepSeek. Nvidia, a key player in the AI sector, surged 8.8% after losing nearly 17% the previous day, marking its largest single-day loss in market value. This rebound was part of a broader recovery in tech stocks, with Apple, Microsoft, and Meta Platforms all posting gains. Investors are also anticipating earnings reports from major tech firms and the Federal Reserve's interest rate decision later this week.
