US equities shifted direction on June 19 as the geopolitical premium that had supported energy prices began to fade. The temporary agreement between the United States and Iran was formally signed in Geneva, and three Saudi supertankers crossed the Strait of Hormuz on the same day. That development offset part of the pressure created by the previous day’s hawkish FOMC shock. With the Strait of Hormuz open again, the market handed leadership back to AI-related chip stocks. The S&P 500 rose more than 1%, the Nasdaq gained nearly 2%, the Dow Jones Industrial Average closed at a fresh high for the third session this week, and the Philadelphia Semiconductor Index jumped more than 6% in a single day to another all-time high. Energy stocks moved in the opposite direction as crude oil fell, making the sector the only clear loser of the session.
Small caps and high-beta shares drive the rebound
In the major indexes, 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 order of performance, from small caps to large caps, showed a clear decline in momentum as market capitalization increased. The Dow was nearly flat by comparison, indicating that the rebound was led mainly by the high-beta names that had suffered the sharpest losses over the previous two sessions. Defensive and blue-chip shares did not follow with the same force. The US-Iran news had largely been priced before the open, and the indexes maintained a steady upward path through the day, recovering most of the losses caused by the prior FOMC-driven selloff by the close.
Intel becomes the chip-chain focus as memory stocks rally
Early in the day, 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 negotiations had been ongoing for more than a year. For Intel’s foundry business, the deal brings in one of the most important external customers; for Apple, it helps diversify dependence on TSMC. Neither company issued a formal response, and the market focused on the directional significance of the cooperation rather than a confirmed corporate statement.
The same Trump post also said that Nvidia had agreed to produce its first chips at Intel and that Elon Musk had committed to jointly building TerraFab, described in the source as the largest wafer fab in history. The Apple cooperation was presented as the third piece of Intel’s foundry map. Intel closed up about 10.5% at $133.82. Apple’s plan to raise prices because of rising memory and storage chip costs also pushed the broader memory chain higher: SanDisk rose more than 11%, Micron gained nearly 9%, and the storage supply chain moved together. Nvidia added nearly 3%, while the Philadelphia Semiconductor Index gained more than 6% to a new record high. Equipment, memory, and computing-power names all advanced, showing that the long-term pricing of AI capital expenditure remained intact after the hawkish dot plot was absorbed by the market.
SpaceX faces pressure while energy gives back geopolitical gains
SpaceX closed down 3.56% at $185.00, marking a second consecutive day of losses. Over the two sessions, the stock fell 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, combined with the hawkish FOMC shock, created a double source of pressure behind the two-day decline. Even so, SpaceX remained up nearly 15% for the week and was still 37% above its IPO price when measured from the first day of trading. The short-term pressure, however, had not yet disappeared.
Energy was the weakest among the 11 S&P 500 sectors. WTI crude fell about 2% on the day to $74.29 per barrel, a near three-month low. Exxon Mobil and Chevron both declined, and the Dow Jones Transportation Average dropped more than 4%. The reopening of Hormuz released the geopolitical premium that had supported the sector, and year-to-date gains of 20% to 40% in parts of the energy trade began to loosen. Energy moved from the week’s strongest group to its weakest. Technology, consumer discretionary, and industrials led the market instead, as funds rotated out of defensive assets and energy and back into the computing-power chain. Money that had left technology stocks after the FOMC shock partially returned once the geopolitical positive news gave traders a reason to re-enter.
Macro pricing now turns to PCE, Micron earnings and Russell rebalancing
In macro markets, the VIX fell 11.06% to 16.40, showing that the fear sparked by the FOMC decision largely faded within one day. 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 for a September rate hike; improved risk appetite merely held volatility down for the moment. Gold fell to $4,210 per ounce, silver also moved lower, and the US dollar index slipped slightly while remaining elevated. According to CoinGecko, Bitcoin closed around $64,026 and Ethereum around $1,734. The crypto market showed no clear response to the geopolitical positive news, and the pressure from hawkish rate expectations had not been lifted.
Next week’s calendar includes PCE data, Flash PMI, and Micron’s earnings. Micron’s guidance is treated in the source as the most direct gauge of AI computing demand. In the previous quarter, one weaker-than-expected guidance update had dragged the entire semiconductor sector sharply lower in a single day. Russell Reconstitution will take effect at next Friday’s close, and mechanical rebalancing flows are expected in the source to create a major increase in trading volume, with small-cap volatility rising at that time.

Chaoxiang Research framed Thursday’s rebound as standing on two legs: the US-Iran signing released the geopolitical premium, while the rally in chip stocks confirmed that the AI theme was still active. The two drivers were both valid, but the source described their durability differently. The geopolitical premium was a one-time event that was realized once the agreement was signed; if Iran reverses course later, the market response would be faster and stronger than the first time. The chip-stock logic was described as more durable. The coordinated rise in Intel, SanDisk, and Micron showed that the rally had breadth across the industry chain, and the pricing of AI capital expenditure had fundamental support. SpaceX carried a separate new variable: once the $20 billion bond issuance is completed, financing pressure and dilution expectations would become a continuing drag on the share price rather than only a valuation adjustment. The next PCE report 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 rebound would be only a pause for breath; if the data softens, the market’s repricing of rate-cut expectations would move quickly.
