New investors may focus on different signals compared to seasoned traders.
Key Highlights
In early May 2026, Michael Burry shared his latest market assessment with his more than 200,000 Substack subscribers. The investor, known for correctly calling the 2008 housing crisis, wrote that “the market has jumped the shark” and warned that “the end of… this… is nigh.”
Burry drew a striking parallel between today’s concentrated rally and the dot-com era. He pointed out that the top 10 stocks by market capitalization have surged 784% over the past year, compared to the 622% peak gain seen in the months before the dot-com bubble burst. The comparison centers on the Philadelphia Semiconductor Index (SOX), which has been a key driver of recent tech outperformance.
To back his bearish view, Burry has reportedly taken a significant leveraged short position using January 2027 put options on the semiconductor ETF SOXX. This move signals a concentrated bet against the chip sector, which has powered much of the broader market’s advance. The S&P 500 and tech-heavy Nasdaq Composite continue to notch fresh records, yet Burry’s warning suggests a sharp revaluation may lie ahead.
The source article, published by Yahoo Finance on Monday, May 18, 2026, did not disclose the exact size of Burry’s position or specific strike prices. The Substack post has since generated widespread attention, with many market participants debating whether the current rally has indeed outpaced historic extremes.

Expert Insights
Burry’s warning arrives at a time when market breadth has been narrow, with a handful of mega-cap names driving the bulk of index gains. His comparison to the pre-dot-com era suggests that extreme price appreciation among leading stocks may not be sustainable. The 784% surge for the top 10 stocks over one year is historically extraordinary, and the fact that it surpasses the 622% peak before the 2000 crash is a data point that many long-only investors may want to consider.
The use of long-dated put options on SOXX indicates Burry is positioning for a multi-year unwind in semiconductor stocks, rather than a tactical hedge. If the chip sector continues to rally in the near term, his position could face time decay, but the 2027 expiry provides room for the thesis to play out. This approach contrasts with short-term bearish bets and suggests a conviction that the semiconductor rally has reached an unsustainable extreme.
For investors, the key takeaway is not to assume the market will follow the same path as the dot-com bust, but to recognize that periods of extreme concentration and momentum often end with sharp revaluations. The absence of a catalyst does not eliminate the risk. Burry’s historical analogy serves as a reminder that when market leadership becomes too narrow, the broader index may become vulnerable to a correction. Investors may want to reassess portfolio concentration, particularly in high-multiple tech and semiconductor names, and consider whether their risk exposure aligns with their long-term objectives.
