Super Micro Computer craters after auditor resigns

The stock has now given back most of the blockbuster gains it made earlier this year.

Shares of Super Micro Computer, the server-maker that’s riding the wave of the AI boom, are crumbling after a company filing revealed that Ernst & Young resigned as its auditor.

While conducting an audit of its annual report, Ernst & Young “raised questions, including about whether the Company demonstrates a commitment to integrity and ethical values consistent with” best business practices around internal controls, according to Super Micro Computer.

The stock is down more than 30% in early trading, and has now given back most of the over 300% year-to-date gain it enjoyed as of March.

Nonetheless, Super Micro said that — other than this — it didn’t have any “disagreements” with Ernst & Young, nor any “reportable events” (both terms as defined by regulations). Other than that, Mrs. Lincoln...

Per the filing, Ernst & Young sent Super Micro a letter saying, in part, that “we are resigning due to information that has recently come to our attention which has led us to no longer be able to rely on managements and the Audit Committee’s representations and to be unwilling to be associated with the financial statements prepared by management, and after concluding we can no longer provide the Audit Services in accordance with applicable law or professional obligations.”

Super Micro announced in late August that it was delaying the filing of its annual report “to complete its assessment of the design and operating effectiveness of its internal controls over financial reporting” — one day after short-seller Hindenberg Research published a scathing report alleging accounting irregularities, questionable governance, and even sanctions evasion at the company. Super Micro has still yet to file that annual report.

About a month later, The Wall Street Journal reported that the US Department of Justice was investigating the company. Both the DOJ and Hindenburg appear to be following up on allegations raised by former employee Bob Luong surrounding the firm’s accounting practices.

Chip stocks post record outperformance of software companies in never-before-seen divergence

One session in 2026 brings one thing we’ve never seen before in markets: a massive divergence between the two big parts of the technology sector.

The VanEck Semiconductor ETF absolutely trounced the iShares Expanded Tech Software ETF today, with the former gaining 3.7% leaving while the latter dropped 2.9%.

The 6.6-percentage point gap is the biggest outperformance for SMH versus IGV on record, going back to December 2011.

Since these two are both parts of a broader technology whole, it’s rare to have one up a ton while the other gets shellacked. The rolling one-year correlation of daily returns for these two ETFs was about 0.8 heading into today.

There have been only three sessions (including today) where the chip stock ETF was up at least 1.5% while the software ETF was down 1.5% or more. We’ve never seen SMH gain 2% while IGV fell 2% before Friday’s session. And there’s been only one session where the reverse happened (November 11, 2024).

The opening trading day of 2026 was phenomenal for the AI picks and shovels trade, while very poor for their more downstream peers.

How and why did this happen? Who knows really, but this looks like the kind of thing where a couple major funds decide to keep their total AI exposure stable but lean into a hardware-over-software tilt when adjusting their positioning at the start of the year, which kicks off intraday momentum that forces everyone else along for the ride.
