Analyst flags Berkshire Hathaway stagnation as precursor to market correction

Financial analyst Rob Isbitts has issued a warning that the stagnant performance and low volatility of Berkshire Hathaway shares may signal an impending stock market crash. Isbitts draws parallels to the pre-2000 dot-com bubble era, arguing that the current market’s extreme concentration in artificial intelligence and semiconductor stocks, alongside the neglect of traditional value assets, creates a top-heavy structure with insufficient margin for error. He suggests that nearly half of the largest US companies have failed to outperform short-term Treasury bills over the past four years, indicating a fragile market environment similar to the collapse of the Invesco QQQ Trust in the early 2000s.

Isbitts, creator of the ROAR Score, asserts that Berkshire Hathaway’s stock has been flat and low-volatility over the past 12 months, a pattern he claims mimics the pre-2000 dot-com bubble era. The article highlights that the headline S&P 500 is dominated by a tight group of AI and semiconductor heavyweights, pushing cap-weighted index concentration to terminal levels. Isbitts notes that nearly half of the largest US companies have failed to outperform a basic 1-3 Month T-Bill ETF over the last four years.

The piece references the 2000 market top, where Berkshire Hathaway dropped roughly 50% from its 1998 peak to its early 2000 low before surging back to new highs after the bubble burst. During the late 1990s, capital indiscriminately flooded into high-beta growth funds, causing traditional value assets to be liquidated to fund the tech chase. Isbitts contends that Berkshire’s underperformance indicates a market where the crowd has pushed the point spread so thin that it possesses zero margin for error.

The analyst predicts a broad downturn similar to the collapse of the Invesco QQQ Trust in the early 2000s, which fell nearly 80% over two years. He argues that the current market’s tech momentum is an optical illusion masking a localized bear market, where index concentration transforms into a momentum fund that will drag the rest of the market down when conditions shift. Unlike the dot-com era, Isbitts expects a lack of a counter-punch from non-tech sectors such as industrials, financials, and consumer staples.

This analysis emerges amidst significant market activity, including the recent debut of SpaceX on the Nasdaq in June 2026. SpaceX opened trading at $150 per share following an IPO priced at $135, valuing the company at approximately $1.77 trillion. Isbitts mentions that such mega-caps could further knock Berkshire down another peg in market weight, reinforcing the view that the headline averages are increasingly driven by a narrow band of speculative assets.
