Berkshire Hathaway's Class B shares have formed a 'Death Cross,' a technical pattern where the 50-day moving average falls below the 200-day moving average, often signaling potential for a major sell-off. This development comes amid investor concerns following Warren Buffett's retirement announcement in May, with the company's stock significantly underperforming the S&P 500 since then. The stock's lag is pronounced, having risen only about 5% since May while the S&P 500 has surged over 35%. This underperformance highlights market hesitancy and the fading of the 'Buffett premium.' The company is sitting on a massive cash pile of $344 billion, which underscores a cautious approach but also a struggle to find lucrative investment opportunities. The market is now closely watching how successor Greg Abel will navigate this new era for the conglomerate.
