<h2>A Week That Proved Markets Are Two Stories Running Simultaneously</h2>
<p>The week of June 22 to 26 2026 will be remembered differently by different market participants depending on which part of the market they were focused on. For oil traders, macro investors, mortgage borrowers, and Federal Reserve watchers, it was a genuinely good week — possibly the best since the Iran war began in late February. For technology investors, particularly those concentrated in the AI chip and semiconductor stocks that have driven so much of 2026's market performance, it was the most painful week since February, a week in which the extraordinary fundamental performance of the companies they own proved insufficient to prevent a significant and sustained selloff in their valuations. Both experiences happened simultaneously in the same market. This divergence — oil and inflation improving while technology valuations corrected — is likely to define the investment debate for the remainder of the summer.</p>
<p>The oil story was the more straightforwardly positive of the two. Brent crude fell from above 100 dollars per barrel at the start of the week to 73.74 dollars by Wednesday's close — its lowest settlement since before the US and Israel launched strikes on Iran in late February 2026. West Texas Intermediate settled at 70.34 dollars, also at multi-month lows. By the end of the week tankers were transiting the Strait of Hormuz in volumes approaching pre-war levels, Iran's Kharg Island crude export terminal had restarted loading operations, and US Energy Secretary Chris Wright confirmed that Iran would return to exporting between 1.5 and 2 million barrels per day following sanctions relief — a supply restoration that the market had been anticipating but whose actual confirmation still moved prices lower. The Treasury Department issued a 60-day general licence authorising Iranian oil sales as part of the US-Iran memorandum of understanding framework, providing the legal clarity that energy traders and shipping companies needed to resume normal operations without fear of sanctions exposure.</p>
<h2>PCE at 2.1 Percent — The Fed's Box Opens</h2>
<p>The macroeconomic capstone of the week arrived Friday morning with the May Personal Consumption Expenditures price index — the Federal Reserve's preferred inflation gauge — coming in at 2.1 percent year-on-year. Core PCE, which strips out food and energy, came in at 1.9 percent — marginally below the Fed's 2 percent target and the first below-target core reading in more than six months. The fall in oil prices from above 100 dollars to below 70 dollars had taken approximately three months to filter through to the PCE data, and its arrival changed the monetary policy conversation in a meaningful way. The CME FedWatch tool's implied probability of a Fed rate hike by December 2026 fell from approximately 30 percent earlier in the week to below 20 percent after the PCE release. The probability of an eventual rate cut — which had been essentially zero as recently as late May — moved into single-digit territory for the first time since the war began. Mortgage rates fell to 6.85 percent. The 10-year Treasury yield dropped below 4.5 percent. Senator Elizabeth Warren's "boxed in" description of Kevin Warsh's predicament loosened slightly. The box had not been removed, but it had grown larger.</p>
<h2>The Tech Selloff: Froth, Rotation, or Something More Serious?</h2>
<p>The week's technology story began on Monday when Alphabet fell sharply on news of AI talent departures and continued deteriorating through Tuesday when South Korea's Kospi fell 10 percent as SK Hynix and Samsung both dropped more than 12 percent in a single session — the worst single-day decline for the Korean technology index in years. Bank of America published a note raising concerns about AI chip valuations and the risk that earnings expectations for technology stocks were too high heading into the July results season, adding further pressure to a sector that had risen approximately 27 percent in the three months prior to the selloff. The VanEck Semiconductor ETF, which tracks the broader chip sector, fell 7 percent on Tuesday alone, its worst single session in many months. The index ended the week down more than 5 percent.</p>
<p>What made the technology story genuinely complex was that the fundamental news from the sector was not bad — it was extraordinary. Micron Technology reported on June 24 the most spectacular quarterly earnings in the history of the US semiconductor industry: revenue of 41.46 billion dollars, quadrupling year-on-year, beating Wall Street estimates by nearly 6 billion dollars. Adjusted earnings of 25.11 dollars per share against estimates of 20.49. Data centre revenue hitting 25 billion dollars. Free cash flow at a record high. Micron stock surged 15 percent on Thursday as the results were digested. SanDisk gained 22 percent. Applied Materials climbed 13 percent. And yet, the Nasdaq still fell for the week. The Apple MacBook price hike — which sent Apple stock down 6 percent on Thursday in its worst single session since the tariff shock of April 2025 — was the most visible expression of a technology industry whose extraordinary profitability at the component level is beginning to create costs at the consumer level that could ultimately dampen demand. Rick Gardner of RGA Investments put it clearly: the downside move in tech stocks is a healthy pullback, since many tech stocks have become overstretched. The tech pullback suggests investors are coming to the realisation that earnings expectations are high, creating a more difficult bar to clear in July's results season.</p>
<h2>Looking Ahead: The Week of June 29</h2>
<p>The week beginning June 29 will test whether the macro improvement visible in the PCE data is durable and whether the technology selloff represents a buying opportunity or the beginning of a more extended recalibration. On the Iran front, the nuclear inspection dispute between the IAEA and Tehran remains unresolved and the 60-day window for a comprehensive deal continues to run. Any deterioration in the Hormuz situation — any return of Iranian restrictions on commercial navigation — would be reflected immediately in oil prices and would reverse some of the inflation relief that produced Friday's positive PCE reading. On the Federal Reserve front, the May PCE data has significantly improved the chance that Warsh's next statement can acknowledge improving conditions without committing to early cuts — a posture that might satisfy neither the hawks who want tighter policy nor the doves who want rate reductions but that represents the appropriate central bank positioning when the data is genuinely improving but uncertainty remains high. For investors, the decision of whether the week of June 22 represented the beginning of a sustained rotation out of technology into value, or a temporary pause in a secular technology bull run, may not be answerable for weeks or months. Markets rarely announce turning points clearly while they are happening.</p>
<h2>What the Rotation Tells Us About Where Money Is Going</h2>
<p>The destination of the capital leaving AI and technology stocks tells its own story about investor psychology in mid-2026. Caterpillar rose nearly 6 percent in one session, contributing approximately 180 points to the Dow's advance on its own — a number that reflects not just the price-weighted quirk of the Dow's construction but the genuine conviction of institutional investors that the physical infrastructure required to power the AI revolution is at least as important a trade as the software and chips that receive most of the public attention. Data centres need electricity. Electricity requires power plants, transformers, cables, and cooling systems. Power plants require turbines, generators, and fuel handling equipment. The physical buildout of AI infrastructure is an enormous industrial and construction undertaking that benefits companies like Caterpillar, Eaton, Emerson Electric, and Quanta Services in ways that are less glamorous than owning Nvidia but that are real, predictable, and less sensitive to valuation compression when sentiment shifts. Healthcare names including Johnson and Johnson and Eli Lilly also advanced as investors rotated toward businesses with stable cash flows and dividend growth that do not depend on the continuation of AI-specific earnings momentum to sustain their investment case. The Dow's advance while the Nasdaq fell is not an anomaly or an error. It is a deliberate and considered reallocation by professional investors who have decided that the extraordinary concentration of capital in AI semiconductor names that characterised the first half of 2026 has reached a level of excess that requires rebalancing. Whether that rebalancing continues through the summer or reverses when hyperscaler earnings in July confirm continued AI infrastructure spending at record levels is the question that will determine whether June 22-26 looks like a paragraph or a chapter in the story of 2026's markets.</p>
