On June 19, US equities shifted their main focus back to the AI chip trade after the geopolitical premium faded. A temporary US-Iran agreement was formally signed in Geneva, and three Saudi supertankers crossed the Strait of Hormuz on the same day. That geopolitical relief outweighed the earlier hawkish shock from the FOMC. The S&P 500 rose more than 1%, the Nasdaq gained nearly 2%, the Dow set another record close for the third day this week, and the Philadelphia Semiconductor Index jumped more than 6% in a single session to a new all-time high. Energy stocks, by contrast, weakened as oil prices fell and became the only losing major sector of the day.
High-beta shares drove the rebound
The S&P 500 closed up 1.08% at 7,500.58, the Nasdaq rose 1.91% to 26,517.93, the Dow added 0.14% to 51,564.70, and the Russell 2000 led with a 2.12% gain to 2,979.77. The pattern of gains declined from small caps to large caps, while the Dow was almost flat. That showed the rebound was led by high-beta names that had been hit hardest over the previous two sessions, rather than by defensive or blue-chip stocks. The US-Iran news had been largely priced before the opening bell, and the indices moved steadily higher through the day, recovering most of the previous session’s FOMC-driven losses by the close.
In an overnight post on Truth Social, Trump confirmed that Apple and Intel had reached a design and foundry cooperation agreement. Intel will initially take on mature-node chips for the iPad and older iPhone models, while flagship products will still be supplied by TSMC. The talks had lasted for more than a year. For Intel’s foundry business, the agreement brings in a major external customer; for Apple, it diversifies reliance on TSMC. Neither company issued an official response, and the market priced the directional significance of the cooperation.
Intel, memory names and Nvidia lifted semiconductors
Trump said in the same post that Nvidia had agreed to produce its first chips at Intel, while Musk had pledged to jointly build TerraFab, described in the source as the largest wafer fab in history. The Apple cooperation formed a third piece in Intel’s foundry map. Intel closed up about 10.5% at $133.82. Apple was said to be preparing price increases because of higher memory and storage chip costs, helping SanDisk rise more than 11% and Micron gain nearly 9%. The broader memory supply chain benefited. Nvidia rose nearly 3%, and the Philadelphia Semiconductor Index gained more than 6% to a record high. Equipment, memory and compute-related names moved higher together, showing that the long-term pricing of AI capital spending remained intact after the hawkish dot plot was released.
SpaceX closed down 3.56% at $185.00, marking its second straight daily decline and bringing the two-day drop to about 8.3%. Bloomberg reported that the company was preparing to issue at least $20 billion of investment-grade dollar bonds to repay a bridge loan due in 2027. Concerns over potential equity dilution, together with the hawkish FOMC impact, created two layers of pressure behind the consecutive declines. SpaceX was still up nearly 15% for the week and stood 37% above its IPO-day issue price, but short-term pressure had not fully cleared.
Energy reversed from the week’s winner to the day’s loser
Energy led losses among the S&P 500’s 11 sectors. WTI crude fell about 2% in one day to $74.29 per barrel, a near three-month low. Exxon Mobil and Chevron both declined, and the Dow Jones Transportation Average fell more than 4%. With the Strait of Hormuz reopened, the geopolitical premium was released, and the earlier year-to-date gains of 20% to 40% in parts of the energy trade began to loosen. Energy moved from the biggest winner of the week to the biggest loser of the day.
Technology, consumer discretionary and industrial shares led the market higher. Capital rotated from defensive and energy positions into the compute chain. Money that had left technology shares after the FOMC shock on the prior day partly returned with the geopolitical relief. The rapid rotation indicated that this capital had not fully exited risk assets; it had been waiting for a reason to re-enter.
Macro assets, crypto and next week’s events
Volatility cooled quickly. The VIX fell 11.06% to 16.40, showing that the fear triggered by the FOMC had largely faded within a day. The 10-year US Treasury yield slipped slightly to around 4.445%, while the 2-year yield stayed above 4.18%. The market did not withdraw its pricing for a September rate hike; improved risk appetite simply suppressed volatility for the moment. Gold fell to $4,210 per ounce, silver also moved lower, and the dollar index edged down but remained elevated. CoinGecko data showed Bitcoin closing near $64,026 and Ether near $1,734. Crypto markets showed no clear response to the geopolitical relief, and pressure from hawkish expectations had not been removed. WTI closed at $74.29 per barrel, its lowest level in almost three months.
Next week will bring PCE data, Flash PMI readings and Micron earnings. Micron’s guidance is treated in the source as the most direct indicator for AI compute demand; in the previous quarter, one weaker-than-expected guidance update dragged the entire semiconductor sector down sharply in a single session. The Russell Reconstitution will take effect at next Friday’s close. Mechanical rebalancing flows will sharply increase trading volume, and small-cap volatility will rise at that time.
TechFlow’s Chaoxiang Research framed Thursday’s rebound as having two supports: the US-Iran signing released geopolitical premium, while chip stocks confirmed that the AI theme remained in place. The two drivers differ in duration. The geopolitical premium is a one-off factor once the agreement is signed, and if Iran reverses course later, the market reaction would be faster and stronger than the first one, according to the source’s framing. The chip-stock logic is more durable because the joint gains in Intel, SanDisk and Micron showed breadth across the supply chain, with fundamental support behind AI capital spending. SpaceX’s two-day decline added a new variable: once the $20 billion bond issue is completed, financing pressure and dilution expectations would become a continued drag on the share price rather than a simple valuation adjustment. PCE is the nearest test. If the data again comes in above expectations, a September rate hike would move from probability to consensus and Thursday’s rally would be only a pause; if the data softens, the market would reprice rate-cut expectations very quickly, as described by the original article.
