Burry's July 30 test: read the filings before trusting the earnings

On July 30, Michael Burry published Trading Post July 30, 2026, a short public opening followed by a subscriber-only trade sheet. He was waiting for earnings and filings from Microsoft, Meta, and other companies before publishing a longer post.

The second sentence is the useful one. Burry is not making a fresh, sweeping claim that every AI stock is worthless. He is saying that the documents behind the current earnings headlines deserve scrutiny because reported profit may not tell the whole economic story.

The post is marked paid. The public opening confirms the direction of his judgment, but not the full trade sheet, position sizes, or the evidence behind each company-specific conclusion. That distinction matters: a visible thesis is not the same thing as a fully disclosed investment case. 1

Earnings quality is the distance between a company's reported profit and the cash-generating economics that sit underneath it. A company can post an impressive earnings-per-share number while investors still need to ask how much of that result came from its operations, how much came from assumptions, and whether those assumptions are becoming more favorable.

Burry's recurring target is the accounting around the AI infrastructure boom. A CNBC background report describes his criticism of companies stretching depreciation schedules on chips and servers, which can make reported profits look smoother while pushing the expense further into the future. That is Burry's allegation and analytical lens, not an established finding about every company he mentions. 2

For a reader, the practical implication is straightforward: do not stop at the headline EPS beat. Read the cash-flow statement and the footnotes. Look for changes in depreciation assumptions, capitalized costs, stock-based compensation, or the definition of an "adjusted" result. Then ask whether management's explanation matches what the filing actually shows. Those checks do not prove a short thesis, but they can tell you whether a good-looking quarter is sturdier than its presentation.

Burry became known for betting against subprime mortgage securities before the 2008 housing crash, a trade chronicled in Michael Lewis's The Big Short. He later ran Scion Asset Management; CNBC reported that Scion's registration was terminated in November 2025. He now publishes public market commentary through Cassandra Unchained. 2

That history explains why this week's excerpt is more than a routine trading update. Burry's familiar method is to look past the market's preferred story and inspect the balance sheet, cash flows, and assumptions that make the story look profitable. In this post, the object of suspicion is not a particular ticker disclosed in public. It is the quality of the earnings material arriving with the next batch of filings.

The right takeaway is therefore a reading habit, not a trade instruction. Burry says he saw "accounting maneuvers and poor earnings quality," but the public portion does not identify a proven accounting breach, quantify a distortion, or establish that a named company will miss its next report. The original post is the place to read his complete argument, while the detailed trade sheet remains subscription-gated. 1
