Stocks are set to end the week in the red, as both the Dow Jones Industrial Average and S&P 500 struggle to hold onto gains.

The S&P 500 is heading for its longest losing streak since February 2020, while the Dow remains relatively unchanged.

On the other hand, Broadcom has experienced a surge in its stock price, reaching all-time highs. This increase is driven by a projected 65% growth in AI-driven sales, which has pushed Broadcom's market capitalization above $1 trillion. This positive momentum has also had a positive impact on the shares of similar companies like Marvell Technology and Taiwan Semiconductor, which have risen by 8% and 4% respectively.

Despite giving up some early morning gains, the tech-heavy Nasdaq Composite, which recently achieved a record close above 20,000, is on track for a strong weekly gain. In contrast, the healthcare sector is facing challenges, particularly UnitedHealth, whose stock has dropped by over 15% following the tragic shooting of its CEO. As economic data suggests the possibility of another interest rate cut from the Federal Reserve next week, concerns about persistent inflation may lead to a more cautious approach in the coming year.
