The SPDR Portfolio S&P 500 ETF (SPLG) closed at $69.72 on January 15, 2025, up 1.81%, as the S&P 500 index surged 1.83% to 5949.91, driven by easing inflation concerns and robust earnings from major financial institutions. The December CPI report showed core inflation rising by 3.2%, slightly below the expected 3.3%, alleviating fears of aggressive Federal Reserve rate hikes. This data, coupled with strong Q4 earnings from banks like Goldman Sachs and Wells Fargo, which exceeded expectations, bolstered investor confidence. The financial sector led the rally, with significant gains in stocks such as Citigroup and Wells Fargo, both up over 7%. Additionally, the decline in Treasury yields, with the 10-year note dropping to 4.66%, further supported growth stocks. The positive sentiment was reflected in the S&P 500 futures, which rose 1.5% to 5,972, indicating strong market optimism.
