TechFlowPost’s selected market column, written by Chaoxiang Research, described Thursday, June 19, as a session in which the main US equity narrative moved back from geopolitics to AI chips. After the US-Iran interim agreement was formally signed in Geneva, three Saudi supertankers crossed the Strait of Hormuz on the same day. The reopening of Hormuz helped offset the hawkish shock from the FOMC. The S&P 500 rose more than 1%, the Nasdaq gained nearly 2%, the Dow set a new closing high for the third day this week, and the Philadelphia Semiconductor Index climbed more than 6% in a single session to another all-time high. Energy stocks moved in the opposite direction as crude oil prices fell, making the sector the only major loser of the day.
Small Caps and High-Beta Stocks Led the Recovery
The S&P 500 closed up 1.08% at 7,500.58. The Nasdaq rose 1.91% to 26,517.93, while the Dow advanced only 0.14% to 51,564.70. The Russell 2000 led the major indexes with a 2.12% gain to 2,979.77. The pattern of gains, strongest in small caps and weaker in large-cap blue chips, showed that the rebound was mainly driven by higher-beta names that had suffered the most during the previous two sessions. Defensive and blue-chip segments did not keep pace. According to the article, the US-Iran news had already been largely priced before the open, and the indexes then moved steadily higher through the session, recovering most of the losses triggered by the prior day’s FOMC impact.
In single-stock news, Trump confirmed early in the morning on Truth Social that Apple and Intel had reached a design and foundry partnership. Under the arrangement described in the post, Intel would initially take on mature-node chips for iPads and older iPhones, while flagship products would continue to be supplied by TSMC. The talks had lasted more than one year. For Intel’s foundry business, the deal brought in a major external customer; for Apple, it diversified dependence on TSMC. Neither company had issued a formal response, so the market was pricing the directional significance of the partnership rather than confirmed operating details. In the same post, Trump also said Nvidia had agreed to produce its first chips at Intel, and Musk had committed to jointly building TerraFab, described as the largest wafer fab in history. The Apple cooperation therefore became the third piece of Intel’s foundry map.
Semiconductors Rose Across the Chain, While SpaceX Fell for a Second Day
Intel closed up about 10.5% at $133.82. Apple’s plan to raise prices because of higher memory and storage chip costs also lifted the memory supply chain: SanDisk rose more than 11%, Micron gained nearly 9%, and related names benefited together. Nvidia advanced close to 3%. The Philadelphia Semiconductor Index rose more than 6% to a record high, with strength across equipment, memory, and computing power. The article argued that the long-term logic behind AI capital expenditure remained intact even after the hawkish dot plot, and the day’s move had breadth across the industry chain rather than being limited to one leading stock.
SpaceX closed down 3.56% at $185.00, its second straight daily decline. Across the two sessions, the stock fell about 8.3%. Bloomberg reported that day that the company was preparing to issue at least $20 billion of investment-grade US dollar bonds to repay a bridge loan maturing in 2027. Concerns over equity dilution, combined with the hawkish FOMC shock, created two layers of pressure behind the two-day slide. Even so, SpaceX was still up nearly 15% for the week and 37% above its IPO-day issue price, though the article said short-term pressure had not yet disappeared.
Energy Gave Back the Geopolitical Premium
Energy was the worst-performing sector among the 11 S&P 500 sectors. WTI crude fell about 2% in a single session to $74.29 per barrel, a nearly three-month low. Exxon Mobil and Chevron declined together, while the Dow Transports Index dropped more than 4%. The reopening of Hormuz released the geopolitical premium that had previously supported oil and energy equities. Earlier year-to-date gains of 20% to 40% in the sector began to loosen, and energy shifted from this week’s biggest winner to the biggest loser. Technology, consumer discretionary, and industrials led on the upside, showing capital rotation away from defensive and energy positions and back into the computing-power chain. Funds that had left technology shares after the FOMC shock partly returned as the geopolitical situation improved.
Macro indicators also moved with the shift in risk appetite. The VIX fell 11.06% to 16.40, suggesting that the anxiety triggered by the FOMC had largely faded within one day. The 10-year Treasury yield slipped slightly to around 4.445%, while the 2-year yield remained above 4.18%. The article said the market had not withdrawn pricing for a September rate hike; improved risk appetite merely suppressed volatility for the moment. Gold fell to $4,210 per ounce, silver also moved lower, and the dollar index edged down while staying elevated. In crypto, Bitcoin closed around $64,026 according to CoinGecko, while Ether ended near $1,734. The crypto market did not show a clear response to the geopolitical relief, and the pressure from hawkish expectations had not been removed.
PCE, Flash PMI, Micron Earnings and Russell Reconstitution Come Next
The next set of catalysts includes PCE data, Flash PMI, and Micron earnings. The article identified Micron’s guidance as the most direct barometer for AI computing-power demand, noting that one weaker-than-expected guidance update in the previous quarter had dragged the entire semiconductor sector sharply lower in a single day. Russell Reconstitution will take effect at next Friday’s close. Mechanical rebalancing flows are expected in the article to greatly increase trading volume, and small-cap volatility will rise at that time.
In its final view, Chaoxiang Research said Thursday’s rebound stood on two legs: the US-Iran agreement released the geopolitical premium, and chip stocks confirmed with actual gains that the AI theme remained active. The two forces are different in durability. The geopolitical premium was a one-off release once the agreement was signed. If Iran reverses course later, the market reaction would be faster and stronger than the first time. The chip-stock logic was described as more durable, because the joint rise in Intel, SanDisk, and Micron showed sector breadth and fundamental support for AI capex pricing. SpaceX’s two-day decline introduced another 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 a simple valuation adjustment. Next week’s PCE report is the nearest test. If the data again comes in above expectations, a September rate hike would shift from a probability to a consensus; if the data weakens, the market would reprice rate-cut expectations at high speed.
