On Thursday, June 19, the main theme in US equities shifted back from geopolitical risk to AI chips. The US-Iran interim agreement was formally signed in Geneva, and three Saudi supertankers crossed the Strait of Hormuz on the same day. With the passage through Hormuz reopened, crude oil prices retreated and the geopolitical premium that had recently supported energy and haven trades faded. The hawkish impact from the FOMC was pushed into the background by the geopolitical news: the S&P 500, Nasdaq and Russell 2000 all rebounded, the Dow Jones Industrial Average closed at a new high for the third day this week, and the Philadelphia Semiconductor Index jumped more than 6% in a single session to set another record high.
High-beta stocks led the rebound
By the close, the S&P 500 was up 1.08% at 7,500.58, the Nasdaq gained 1.91% to 26,517.93, the Dow rose 0.14% to 51,564.70, and the Russell 2000 led the major indexes with a 2.12% advance to 2,979.77. The pattern of returns moved from stronger gains in small caps to smaller gains in large caps, while the Dow was almost flat. That distribution showed that the rebound was mainly driven by the high-beta names that had fallen the most over the previous two sessions, while defensive and blue-chip stocks did not keep pace. The US-Iran news had already been largely priced in before the opening bell, and the indexes moved steadily higher through the day, recovering most of the losses triggered by the prior day’s FOMC shock.
Macro assets also reflected a rapid easing of stress. The VIX dropped 11.06% to 16.40, meaning the fear sparked by the FOMC a day earlier largely faded within one session. The 10-year US Treasury yield edged down to around 4.445%, while the 2-year yield stayed above 4.18%. The market did not withdraw its pricing of a September rate hike; improved risk appetite simply held volatility in check for the moment. Gold fell to $4,210 per ounce, silver also declined, and the US dollar index eased slightly while remaining elevated. In crypto, CoinGecko data showed Bitcoin closing around $64,026 and Ether around $1,734. The crypto market did not show a strong reaction to the geopolitical relief, and the pressure from hawkish expectations remained in place. WTI crude settled at $74.29 per barrel, marking a near three-month low.
Intel’s Apple deal lifted the broader chip chain
In the early morning, Donald Trump confirmed on Truth Social that Apple and Intel had reached a design and foundry cooperation agreement. Under the arrangement described in the post, Intel will initially take on mature-process chips for iPads and older iPhone models, while Apple’s flagship products will continue to be supplied by TSMC. The talks had been underway for more than a year. For Intel, the foundry business gained its most important external customer; for Apple, the partnership diversifies reliance on TSMC. Neither company issued a formal response, so the market was trading the directional significance of the agreement rather than a company announcement.
The same Truth Social post also said Nvidia had agreed to produce its first chips at Intel, while Elon Musk had committed to jointly building TerraFab, described in the source as the largest wafer fab in history. The Apple partnership became the third piece in Intel’s foundry map. Intel closed up about 10.5% at $133.82. Apple’s planned price increase due to higher memory and storage chip costs also lifted the memory supply chain: SanDisk rose more than 11%, Micron gained nearly 9%, and the broader storage chain advanced together. Nvidia added close to 3%, and the Philadelphia Semiconductor Index rose more than 6% to a new historical high. Gains extended from equipment to storage to compute, showing that the long-term AI capital expenditure trade remained supported even after the hawkish dot plot had landed.
SpaceX remained under pressure while energy reversed lower
At the other end of the stock move, SpaceX closed down 3.56% at $185.00, marking a second consecutive 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. The financing pressure from that bond issue, concerns over equity dilution and the hawkish FOMC impact together formed the two sources of pressure behind the back-to-back declines. Even so, SpaceX was still up nearly 15% for the week and, measured from the first day of its IPO, remained 37% above its offer price. The short-term pressure, however, had not yet cleared.
Energy was the weakest of the 11 S&P 500 sectors. WTI crude fell about 2% in the session to $74.29 per barrel, Exxon Mobil and Chevron both declined, and the Dow Jones Transportation Average dropped more than 4%. With the Strait of Hormuz reopened, the geopolitical premium embedded in oil and energy equities was released. The two- to four-tenths year-to-date gains previously seen in energy-related assets began to loosen, turning the sector from the week’s biggest winner into the day’s biggest loser. Technology, consumer discretionary and industrials led the market, showing a rotation of capital away from defensive and energy trades and back toward the compute chain. Funds that had left technology shares after the FOMC shock partly returned once the geopolitical relief trade was in place.
PCE, Flash PMI and Micron earnings come next
The next sequence of events will include PCE data, Flash PMI and Micron’s earnings report next week. In the original TechFlow analysis, Micron’s guidance was described as the most direct wind vane for AI compute demand. In the previous quarter, one guidance update that came in below expectations dragged the entire semiconductor sector sharply lower in a single session. The Russell Reconstitution will also take effect at next Friday’s close. Mechanical rebalancing flows are set to drive a large increase in trading volume, and small-cap volatility will rise at that time.
The original article, written by Chaoxiang Research, framed Thursday’s rebound as standing on two legs: the US-Iran signing released the geopolitical premium, while the chip stocks confirmed through actual gains that the AI theme was still intact. Both lines of logic held, but their time horizons were different. The geopolitical premium was treated as a one-off release once the agreement was signed; if Iran reverses course later, the market response would be faster and stronger than the first reaction. The chip-stock logic was more durable, because the linked rise in Intel, SanDisk and Micron showed that the session had breadth across the industrial chain. The two-day decline in SpaceX introduced a new variable: if the $20 billion bond issuance is completed, financing pressure and dilution expectations will become a continuing drag on the share price rather than a simple valuation adjustment. Next week’s PCE data is the closest test. If the data again comes in above expectations, the September rate hike moves from probability to consensus and Thursday’s rebound becomes only a pause for breath. If the data weakens, the market will reprice rate-cut expectations at a faster speed.
