Bank Stocks Rally

Goldman achieved a new record in equity trading revenue, exceeding expectations with $4.31 billion in Q4 revenues. Both banks' strong performances contributed to lifting investor sentiment across the financial markets.

Energy Market Dynamics

In the energy sector, oil prices fell significantly, driven by easing geopolitical tensions in Iran. The price of Brent crude dropped to $63.79 per barrel, and West Texas Intermediate fell to $59.19.
