Berkshire Hathaway’s stagnant stock price over the past year may be one of the clearest warning signs of a top-heavy market, according to an analysis by Rob Isbitts on Barchart. The conglomerate’s class B shares have been flat and low-volatility while the S&P 500 is dominated by a tight group of AI and semiconductor stocks, a pattern that closely resembles the lead-up to the dot-com bubble’s peak in 2000. In the late 1990s, Berkshire underperformed dramatically as capital fled value stocks for tech names, dropping roughly 50% from its 1998 peak to its early 2000 low before the Nasdaq ultimately collapsed nearly 80%. Today, nearly half of the largest U.S. companies have failed to beat a basic risk-free T-bill ETF over the last four years, signaling a quiet bear market beneath the surface. Isbitts warns that extreme index concentration has turned the S&P 500 into a momentum fund that will drag the broader market down when sentiment shifts, with non-tech sectors unlikely to provide a counterpunch.
