Bristol-Myers Squibb Company (BMY) is currently being closely watched due to significant volatility in the Information Technology sector. After a period of consolidation, major semiconductor stocks like NVIDIA (NVDA) and Broadcom (AVGO) showed bullish patterns.

However, on October 15, the landscape changed dramatically when ASML Holdings issued disappointing guidance for 2025, causing its stock to plummet over 16%. This was the company's worst trading day since the pandemic. Other semiconductor stocks, including KLA Corporation (KLAC), Lam Research (LRCX), and Applied Materials (AMAT), also experienced substantial declines, with losses ranging from 11% to 15%.

Despite this turmoil, leading companies like NVDA, Taiwan Semiconductor Manufacturing Company (TSM), and AVGO managed to hold their ground, with losses between 2.6% and 4.5%. As a result, major semiconductor ETFs like SOXX and SMH saw a more moderate decline of around 5%. Overall, major indices fell between 0.7% and 1.4%, and the NYSE breadth remained slightly negative at -157, indicating that the selling pressure was concentrated primarily in the Information Technology, Energy, Healthcare, and Industrials sectors. The advancing volume versus declining volume on the NYSE remained neutral at 50%, reflecting a mixed market sentiment.
