'The Big Short' investor Michael Burry Wednesday said the stock market's unusually long stretch without a broad-based selloff is a warning sign that a reversal could be building beneath the surface.

Historic Streak Of Market Calm Burry shared a CNBC report on X that referenced his Substack post, in which he cited research from BTIG technical strategist Jonathan Krinsky showing Wednesday marked the 182nd consecutive trading session without at least 80% of New York Stock Exchange volume declining.

"That sort of technical factor on its own is easy to ignore," Burry said in his blog, adding that he has written about fundamental reasons for such a streak since November 2025.

Krinsky said every year for the past 30 years has had at least five such sessions, so a 2026 without one would be the first in at least three decades.

Stock market tranquility is almost unprecedented.
