TechFlowPost’s June 19 US market review by Chaoxiang Research described a session in which the geopolitical premium faded and the market returned its main focus to AI chips. On Thursday, the temporary US-Iran agreement was formally signed in Geneva, and three Saudi supertankers crossed the Strait of Hormuz that same day. The geopolitical relief offset the hawkish impact from the FOMC. The S&P 500 rose more than 1%, the Nasdaq gained nearly 2%, the Dow posted its third record close of the week, and the Philadelphia Semiconductor Index jumped more than 6% in a single day to another all-time high. Energy stocks, hit by falling crude prices, were the only losing sector of the session.
Small caps and high-beta names led the index rebound
Among the major indexes, 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 the market with a 2.12% gain to 2,979.77. The gain profile moved from small caps to large caps in descending order, while the Dow was almost flat. According to the report, that pattern showed the rebound was mainly driven by high-beta stocks that had fallen hardest during the previous two sessions, while defensive and blue-chip names did not keep pace. The US-Iran news had already been substantially priced before the open, and the indexes moved steadily higher through the session, recovering most of the losses caused by the prior day’s FOMC shock.
Another major driver came from Trump’s early-morning post on Truth Social. He confirmed that Apple and Intel had reached a design and foundry cooperation agreement, under which Intel would initially take on mature-node chips for the iPad and older iPhone models, while flagship products would continue to be supplied by TSMC. The negotiations had been under way for more than a year. For Intel’s foundry business, the deal brought in a major external customer; for Apple, it reduced reliance on TSMC. Neither company had issued an official response, and the market was pricing the directional significance of the arrangement.
Intel, memory stocks and the compute chain moved together
In the same post, Trump also said Nvidia had agreed to produce its first chips at Intel, and that Musk had committed to co-building TerraFab, described in the source as the largest wafer fab in history. The Apple cooperation became 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 higher memory and storage chip costs lifted the broader memory chain: SanDisk rose more than 11%, and Micron gained nearly 9%. Nvidia advanced nearly 3%, while the Philadelphia Semiconductor Index rose more than 6% to a record high. The rally extended from equipment to memory to compute, and the report said the long-term logic of AI capital expenditure remained intact after the hawkish dot plot was released.
SpaceX moved in the opposite direction. The stock closed down 3.56% at $185.00, marking a second straight decline, with a two-day cumulative drop of about 8.3%. Bloomberg reported that the company was preparing to issue at least $20 billion of investment-grade US dollar bonds to repay bridge loans maturing in 2027. Concerns about equity dilution, combined with the hawkish FOMC shock, created a double source of pressure. The stock was still up nearly 15% for the week and 37% above its IPO-day issue price, but the short-term pressure had not yet cleared.
Energy shifted 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 a single day to $74.29 per barrel. ExxonMobil 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 built up earlier. The report noted that the sector’s year-to-date gains of 20% to 40% began to loosen, turning energy from the week’s biggest winner into the session’s biggest loser. By contrast, technology, consumer discretionary and industrial stocks led gains as capital rotated away from defensive and energy names and back into the compute chain.
The speed of that rotation was a central feature of the session. Money that had left technology stocks after the FOMC shock on the previous day returned in part once geopolitical relief arrived. The report characterized the move as evidence that this capital had not truly exited the market; it had been waiting for a reason to re-enter. Within equities, the clearest expression of that return was the full-chain advance across AI-related semiconductors, from Intel and Nvidia to SanDisk and Micron.
Volatility cooled while rate pricing remained in place
Macro assets also reflected the rapid cooling of fear. The VIX fell 11.06% to 16.40, meaning the panic triggered by the FOMC had 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 report said the market had not withdrawn its pricing for a September rate hike; improved risk appetite had only temporarily suppressed volatility. Gold fell to $4,210 per ounce, silver also moved lower, and the US Dollar Index slipped slightly while remaining at an elevated level.
Crypto assets did not react strongly to the geopolitical relief. Bitcoin, based on CoinGecko data, closed near $64,026, while Ethereum finished around $1,734. The report said the pressure from hawkish expectations had not yet been removed for the crypto market. WTI crude settled at $74.29 per barrel, marking a nearly three-month low.
PCE, Flash PMI and Micron earnings come next
The next sequence of events listed in the report includes PCE data, Flash PMI and Micron’s earnings. Micron’s guidance was described as the most direct barometer for AI compute demand. In the previous quarter, one weaker-than-expected guidance update from Micron had dragged down the entire semiconductor sector in a single session. The Russell Reconstitution will take effect after next Friday’s close, and mechanical rebalancing flows are expected in the source to produce a sharp increase in trading volume, with small-cap volatility rising at that time.
In its “Chaoxiang View,” the source summarized Thursday’s rebound as having two legs: the US-Iran agreement released the geopolitical premium, while chip stocks confirmed through actual gains that the AI theme remained in place. The two drivers, however, had different durations. The geopolitical premium was treated as a one-off factor, realized once the agreement was signed. The chip-stock logic was described as more durable, because the joint gains in Intel, SanDisk and Micron gave the rally broader industrial-chain support, while AI capital expenditure still had fundamental backing. The report also highlighted a new variable behind SpaceX’s two-day decline: 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.
