Bear Market

The Philadelphia Semiconductor Index closed at 11,674 today. Down 20.3% from its late-June record of 14,655. That crosses the line. Bear market.

Twenty-five days ago, the SOX hit an all-time high. AI demand was insatiable. Memory prices were surging. SK Hynix raised $26.5 billion in the largest foreign IPO in U.S. history. The narrative was unanimous: compute demand has no ceiling.

One group disagreed. Not with words — with filings.

The Scoreboard

AMAT closed at $529.66 today. Down 5.57% on the session. Down 28% from its all-time high of $739. Both of Dickerson's sales are deeply validated. Neither was programmatic.

The Distinction That Matters

We audited every major AI-hardware insider sale in June. The finding: roughly $340 million in discretionary selling versus $374,000 in discretionary buying. A 900-to-1 ratio.

But not all selling is created equal. Jensen Huang sold $226 million of NVIDIA shares on a 10b5-1 plan filed in March 2025. He would have sold at any price. That's the noise floor.

Gary Dickerson sold $104.7 million of Applied Materials shares in two waves — $49.2M at $590, then $55.5M at $735 two weeks later. Both transactions coded "S" with no 10b5-1 notation. He chose those prices. He chose those days. And he sold the second time the exact week the SOX peaked.

That distinction — mechanical versus discretionary — is the difference between data and signal. Every 10b5-1 sale in the complex executed on schedule regardless of price. Dickerson waited for a price, then acted. Twice.

$3.3 Trillion

That's how much semiconductor market value has evaporated since June 22. The SOX is down 11% this week alone — its worst weekly rout since the April 2025 tariff meltdown. Marvell, ARM, and Intel have each plunged more than 30% from their peaks.

Today's trigger was Moonshot's Kimi K3 — a 2.8-trillion-parameter open-weight model from China that benchmarks claim rivals the best U.S. systems. Traders are calling it a new DeepSeek moment. Whether those benchmarks hold up under independent testing is an open question.

What isn't open: the AI capex sustainability debate that the discretionary sellers were implicitly answering when they filed their Form 4s.

TSM reported a 77% earnings gain this week. Stock fell. ASML posted strong results. Stock fell. The fundamentals were never the problem. The valuation of those fundamentals was. And the insiders who sold discretionarily at the peak were pricing that gap before the market was.

What the Filings Said

This is the third post in our AI-hardware insider arc. "500 to 1" documented the ratio. "Not on Autopilot" separated the signal from the noise floor. This post is simpler: the bear market happened. The discretionary sellers were right.

Across the eleven largest AI-hardware names in June, 63 insider sales totaling $155.6 million versus one purchase of $374,000 — a single AVGO director buying into a post-earnings dip. The complex has now lost a fifth of its value. The only insider who bought is the only one who's underwater.

The signal was in the filings. It always is.
