Samsung printed the biggest quarter in its history. Revenue surged. Memory demand exploded. Every number was up massively from a year ago. And the stock fell 7% in Seoul. In New York, Micron dropped 7%. KLA, Marvell, Broadcom, AMD — all down. The semiconductor ETF lost 5% for the third time in eight sessions. The bar is too high. Even blowout results can't clear it. Meanwhile, Iran attacked a Qatari oil tanker near the Strait of Hormuz — during the Supreme Leader's funeral — and the U.S. responded by revoking the waiver that had allowed Iran to sell oil. Brent crude jumped 2.4%. WTI spiked to $70. The two forces that powered the Dow to 53,000 — falling chip costs and falling oil — both reversed on the same day. The Dow hit a new intraday high this morning. By the close it was down 131 points. The S&P lost half a percent. The Nasdaq dropped 1.2%. SpaceX joined the Nasdaq-100 before the open and had a front-row seat to the wreck.
The Close
Ugly reversal. The Dow touched a new all-time high in the first hour, then gave it all back and closed down 131 points. The S&P fell 0.5%. The Nasdaq dropped 1.2%. Only 41% of U.S. stocks advanced. The morning started green — then Samsung's sell-the-news reaction hit U.S. chips, and the Iran tanker attack pushed oil higher, and the combination turned a record-chasing open into a red close.

SpaceX's first day in the Nasdaq-100 was a non-event. The stock rose 1% to $158.77. Most of the $4.3 billion in forced passive buying from index funds had already happened by Monday's close and Tuesday's open — the funds front-ran the rebalance. By the time the bell rang, there was nothing left to buy. The stock entered the blue-chip index 28% below its $219 peak and 18% above its $135 IPO price. It outperformed the Nasdaq on a day the index fell 1.2%, but that's a low bar. We previewed this day for two weeks. The answer is: the inclusion was priced in.
Samsung's preliminary Q2 numbers were enormous by any historical standard. Revenue was up sharply. Memory demand from AI data centers was strong across the board. But the stock fell 7% in Seoul because the expectations heading in were even bigger. The KOSPI dropped with it. By the time U.S. markets opened, the chip selloff was already baked. Micron lost 7% — its fifth down day in six. The semiconductor ETF fell 5%. Mike Bailey at FBB Capital Partners summed it up: "Expectations are up, and fundamentals are struggling to meet these sky-high demands."
Iran attacked a Qatari oil tanker near the Strait of Hormuz. The strike happened during the funeral processions for Ayatollah Khamenei — while hundreds of thousands packed Tehran's streets. Bloomberg reported that the U.S. responded by revoking the waiver that had allowed Iran to sell oil at market prices since the ceasefire. That waiver was part of the June 17 MOU. Pulling it means Iran's oil revenue gets cut off again. Brent jumped 2.4% to $73.75. WTI rose 2.3% to $70.13. Shell hiked its gas production guidance on the same day. The oil story that had been "falling, falling, falling" for two weeks just hit a speed bump.
Vertex announced a $10 billion deal to buy Crinetics Pharmaceuticals — the stock jumped 99%. JPMorgan raised Apple's price target to $345. But the gains in health care and energy couldn't offset the damage in tech.
What The Market Is Pricing In
When a stock runs up for months on the promise of great earnings, and then the great earnings arrive and the stock drops — the market is telling you that the good news was already in the price. Everyone who wanted to buy had already bought. The report didn't disappoint. The expectations did. On Wall Street they call it sell the news. It's one of the oldest patterns in the book: the stock runs before the event, then falls when the event happens, even if the news is good. Samsung just gave you a textbook case.
Here's the chain. Micron blew out earnings on June 25. The stock surged 17%. Memory was the hottest trade on the planet. Samsung's Q2 report was the next shoe — if Samsung confirmed Micron's demand story, the chip rally would extend. Samsung confirmed it. Revenue up. Memory demand strong. AI everywhere. And the stock fell 7%. Micron fell 7%. The semiconductor ETF fell 5%. The confirmation didn't matter because the price had already captured the confirmation. That's the signal: the chip trade has moved from "buy the earnings" to "sell the news." The marginal buyer is gone.
Then Iran reminded everyone that the oil story isn't over. Attacking a Qatari tanker during the funeral — and drawing a U.S. response that revokes the oil waiver — reintroduces a risk the market had spent two weeks removing. WTI was at $67 on Wednesday. It's at $70 today. If the waiver stays revoked and Iran loses its ability to sell oil, the inflation math changes. The June CPI that was supposed to show falling energy costs may not fall as far as the market expected.
Samsung beat every estimate, the stock fell 7%, and the U.S. revoked Iran's oil sales waiver on the same afternoon — and the market is telling you that the two trades that carried the Dow to 53,000 (falling chip costs and falling oil) both hit a wall today. The chip trade is selling great news. The oil trade is repricing geopolitical risk. If both persist — if Micron and Samsung keep falling despite strong results, and if oil keeps climbing because the Iran deal is fraying — the Dow gives back its gains and the inflation story stops improving.
I watched Cisco report the best quarter in its history in February 2000. The stock barely moved. Everyone already owned it. The expectations were in the price. The stock peaked two weeks later and fell 80% over the next two years. I'm not saying Samsung is Cisco. The demand is real. The revenue is real. But when the best quarter in history gets sold, the trade is crowded and the next move is down — at least until the expectations reset.
What's Next
Three things I'm watching this week:
01 — Does the oil waiver stay revoked?
Bloomberg reported the U.S. pulled Iran's oil sales waiver Tuesday. If the revocation holds, Iran loses its main economic incentive to negotiate. Oil goes back to $75 and the inflation math worsens. If it's a warning shot — pulled for a few days to punish the tanker attack, then reinstated — oil falls back and the deal survives. Watch whether the State Department confirms or walks back the Bloomberg report by Wednesday morning. The waiver is the economic backbone of the MOU. Without it, the deal loses its structure.
02 — FOMC minutes Wednesday July 8 at 2 PM
The minutes from the June 17 meeting arrive tomorrow. The market has moved far since that meeting: NFP at 57,000, ISM prices falling, Warsh softening. But if the minutes show broad consensus around hiking — not just nine dots but a unified committee — the "bad news is good news" trade from last week reverses, because it means the Fed's default is still to tighten, and today's oil spike gives them more reason to do it. If the minutes show a narrow majority with Warsh cautious and several officials favoring a hold, the market exhales.
03 — Samsung's full report and chip demand guidance
Today's Samsung number was preliminary. The full Q2 report arrives in two to three weeks with segment detail, margins, and forward guidance. If Samsung guides above expectations for the second half — citing continued AI memory demand — the sell-the-news reaction is temporary and the chips bottom. If the guide is cautious — if Samsung signals that memory pricing is peaking or that data center orders are plateauing — the selloff extends and the SOX index heads for a full correction. The preliminary number told you demand was strong. The guidance will tell you if it stays that way.
The best chip quarter of the year just got sold. Iran attacked a tanker during a funeral. Oil spiked. The oil waiver got pulled. And the two trades that defined the summer — falling chip costs and falling oil — both reversed on the same afternoon. Tomorrow the Fed's words from three weeks ago land in a market that looks nothing like the one that heard them. The second half just got harder.

That's it for today. See you tomorrow after the close.
