On November 17, 2025, Apple Inc. shares fell to $267.69 (-1.73%) during live trading, following news that Warren Buffett’s Berkshire Hathaway reduced its Apple holdings by about 15% in the third quarter. This move, disclosed in an SEC filing, triggered selling pressure as investors reacted to the shift by one of Apple’s largest shareholders. Additionally, Apple lost a major patent case regarding blood-oxygen sensors in its Apple Watches, resulting in a $634 million penalty. These company-specific developments are weighing on the stock, which is underperforming the broader market despite recent strong quarterly results and a generally bullish medium-term trend. The combination of Berkshire’s stake reduction and the patent ruling are the primary drivers of today’s decline, outweighing broader market volatility.
