On Thursday, June 19, the main storyline in U.S. equities shifted back from geopolitical risk to AI chips. A temporary U.S.-Iran agreement was formally signed in Geneva, and three Saudi supertankers crossed the Strait of Hormuz on the same day, cooling the market’s pricing of supply-disruption risk. The positive geopolitical development offset part of the hawkish shock from the FOMC. The S&P 500 and Nasdaq reversed two consecutive days of losses, the Dow posted its third record close of the week, and the Philadelphia Semiconductor Index gained more than 6% in a single session to reach another all-time high. Energy stocks, pressured by falling oil prices, were the only clear losing group.
Indexes recovered from the FOMC setback as small caps and high-beta names led
The major indexes finished higher across the board. The S&P 500 rose 1.08% to 7,500.58, the Nasdaq advanced 1.91% to 26,517.93, the Dow gained 0.14% to 51,564.70, and the Russell 2000 led with a 2.12% rise to 2,979.77. The ranking of gains, from small caps to large caps, showed that the strongest rebound came from high-beta segments that had been hit hardest over the previous two sessions. The Dow was nearly flat by comparison, indicating that defensive and blue-chip shares did not fully participate in the move. The U.S.-Iran news had already been priced before the open, and the indexes maintained a steady upward path through the day, recovering most of the prior session’s FOMC-driven decline by the close.
Sector rotation also showed that part of the capital that had exited technology shares after the FOMC shock had not left the market entirely. It moved back into the computing-power chain once geopolitical pressure eased. Technology, consumer discretionary and industrials led the advance, while defensive assets and energy lost support. The speed of the rotation suggested that the rebound was not evenly distributed across the market, but was concentrated in the higher-elasticity areas that had been under the most pressure.
Intel drew support from the Apple foundry narrative as the semiconductor chain rallied
Early in the morning, Trump confirmed on Truth Social that Apple and Intel had reached a design and foundry cooperation arrangement. Intel will initially take on mature-node chips for iPads and older iPhone models, while Apple’s flagship products will still be supplied by TSMC. The talks had lasted more than a year. For Intel’s foundry business, the cooperation brings in a major external customer; for Apple, it diversifies dependence on TSMC. Neither company issued a formal response, and the market was pricing the directional significance of the arrangement.
The same post also said Nvidia had agreed to produce its first chips at Intel, and that Musk had committed to co-building TerraFab, described as the largest wafer fab in history. The Apple cooperation became the third piece in Intel’s foundry map. Intel closed up about 10.5% at $133.82. Apple’s planned price increase, tied to rising memory and storage chip costs, benefited the broader memory chain: SanDisk rose more than 11% and Micron gained nearly 9%. Nvidia advanced almost 3%, while the Philadelphia Semiconductor Index climbed more than 6% to a record high. Equipment, memory and computing-power names all moved higher, showing that the long-term pricing of AI capital expenditure remained intact even after the hawkish dot plot.
SpaceX fell for a second day while energy turned from winner to loser
SpaceX closed down 3.56% at $185.00, marking its second consecutive daily loss. The two-day decline reached about 8.3%. Bloomberg reported that the company was preparing to issue at least $20 billion of investment-grade dollar debt to repay a bridge loan maturing in 2027. Financing pressure, concerns over equity dilution and the hawkish FOMC shock combined to weigh on the stock in the short term. SpaceX was still up nearly 15% for the week and 37% above its IPO price from the first day of trading, but the two-day decline showed that near-term pressure had not disappeared.
Energy was the weakest of the 11 S&P sectors. WTI crude fell about 2% on the day to $74.29 per barrel, hitting a nearly three-month low. Exxon Mobil and Chevron both declined, while the Dow Jones Transportation Average fell more than 4%. The reopening of the Strait of Hormuz released the geopolitical premium that had accumulated in oil and energy shares. Earlier year-to-date gains of roughly 20% to 40% in energy stocks began to loosen, and the sector shifted quickly from this week’s strongest winner to the day’s largest loser.
Volatility retreated, while crypto showed little reaction
Macro indicators pointed to a fast recovery in risk appetite. The VIX dropped 11.06% to 16.40, meaning the fear triggered by the previous day’s FOMC message largely faded within one session. The 10-year U.S. Treasury yield edged down to around 4.445%, while the 2-year yield stayed above 4.18%. The market did not remove its pricing for a September rate increase; improved risk appetite simply suppressed volatility for the moment. Gold fell to $4,210 per ounce, silver also moved lower, and the dollar index slipped slightly while remaining elevated. According to CoinGecko, Bitcoin closed near $64,026 and Ethereum near $1,734. The crypto market showed no clear response to the geopolitical improvement, and pressure from hawkish expectations remained in place.
Next week will bring PCE data, Flash PMI and Micron’s earnings report. Micron’s guidance is viewed as the most direct signal for AI computing-power demand. In the previous quarter, guidance below expectations dragged the entire semiconductor sector sharply lower in one session. Russell Reconstitution will take effect at next Friday’s close, and mechanical rebalancing flows will sharply increase trading volume, raising small-cap volatility at that time. TechFlow’s view is that Thursday’s rebound had two supports: the U.S.-Iran signing released geopolitical premium, while chip stocks confirmed through actual gains that the AI theme was still active. The geopolitical premium was a one-off release once the agreement was signed. The chip rally had more industrial breadth, as Intel, SanDisk and Micron rose together. For SpaceX, once the $20 billion bond issuance is completed, financing pressure and dilution expectations will become a continuing drag on the share price rather than only a valuation adjustment. If next week’s PCE data again comes in above expectations, the September rate increase could move from probability to consensus; if the data softens, the market’s repricing of rate-cut expectations would accelerate quickly.
