Records Again: The Market That Refuses to Quit
Global financial markets produced one of the most psychologically intriguing sessions of 2026 on Wednesday, May 13, when the United States equity market simultaneously absorbed its worst monthly producer price inflation reading in more than three years, kept crude oil firmly above $100 per barrel amid the unresolved US-Iran ceasefire crisis, and still managed to push the S&P 500 and the Nasdaq Composite to fresh all-time records. The S&P 500 rose 0.58 percent to close at 7,444.25 — a new intraday and closing record. The Nasdaq Composite surged 1.2 percent to end at 26,402.34 — also a record. The Dow Jones Industrial Average was the sole major index left out of the celebration, shedding 67.36 points, or 0.14 percent, to close at 49,693.20. The Russell 2000 small-cap index retreated sharply, declining 0.97 percent, underlining the increasingly narrow and bifurcated character of the 2026 bull market: technology and artificial intelligence up, everything else struggling.
The session was the fourth consecutive day in which AI-linked semiconductor and technology stocks powered the market to gains that masked widespread declines in the broader index. According to data provider FactSet, roughly two-thirds of the S&P 500's 500 constituent companies actually closed lower on May 13 — yet the index still posted a record. That mathematical outcome is only possible when a small number of very large companies gain enough to outweigh the collective decline of the majority. On this day, those companies were Nvidia, Micron Technology, Apple, and a small cohort of other technology names that together contributed almost all of the index's advance. Outside technology, the day was significantly negative for utilities, retail, financials, and industrials — a pattern consistent with rising Treasury yields and the inflationary drag of higher energy prices flowing through to consumer spending and corporate margins.
The Inflation Numbers That Couldn't Stop the Bulls
Wednesday's most significant economic data release was the April 2026 Producer Price Index report from the United States Bureau of Labor Statistics. The report showed that wholesale prices rose a seasonally adjusted 1.4 percent in April on a monthly basis — the largest single-month increase since March 2022 and significantly above the Dow Jones consensus forecast of 0.5 percent. On an annual basis, the producer price index rose 6 percent in April — the biggest year-on-year increase since December 2022. Both the monthly and annual readings were materially hotter than expected, and both can be traced substantially to the surge in energy costs caused by the disruption of global oil supply through the Strait of Hormuz as a consequence of the US-Iran war.
The April Consumer Price Index, released the previous day on May 12, had already shown annual headline inflation at 3.8 percent — the highest since May 2023 — with energy costs alone rising 17.9 percent over the past year. The core CPI reading of 2.8 percent year-on-year also remained well above the Federal Reserve's 2 percent target. Wednesday's PPI data confirmed that inflationary pressure is not limited to the consumer level but is also embedded in the wholesale supply chain — a signal that higher prices may persist for months even after oil markets eventually normalise. Chris Zaccarelli of Northlight Asset Management noted that the data makes clear that the Iran war is affecting not just headline energy prices but also core inflation, which came in above expectations. Wolfe Research commented that even in the event of a US-Iran ceasefire deal, they do not expect 10-year Treasury yields to return to pre-war levels, projecting only a partial reversal of approximately 10 to 15 basis points.
The 20-year and 30-year US Treasury yields surpassed 5 percent in the days surrounding the May 13 session — a level that analysts described as worrying for yield-sensitive assets and for sectors that depend heavily on cheap borrowing. The utilities sector, the worst-performing group in the S&P 500 on the day, fell 1.1 percent and has now lost almost 5 percent in May alone. Since reaching a 52-week high on February 27 — the day before the Iran war began — utilities have fallen 6 percent in total. Rate-sensitive financials and real estate investment trusts also underperformed.
The Stars of the Session: Nvidia, Micron, Apple, Cisco
Nvidia Corporation, the semiconductor giant whose graphics processing units have become the defining hardware of the artificial intelligence revolution, rose more than 2 percent in regular trading on May 13 and was set for a sixth consecutive session of gains heading into May 14 premarket activity, climbing an additional 1.9 percent overnight. Nvidia CEO Jensen Huang made a surprise appearance at the Trump-Xi summit in Beijing, joining the delegation of 16 top American business executives that accompanied the president on the trip. His presence at the diplomatic summit was interpreted by markets as a signal that discussions about the resumption of advanced chip exports from the United States to China — a key flashpoint in the bilateral technology rivalry — may be progressing. Nvidia's participation in those discussions directly affects its revenue from one of its largest potential markets.
Micron Technology, the memory chip manufacturer whose stock soared more than 37 percent in the week preceding the May 13 session, rose more than 4 percent on the day and has now gained approximately 53 percent over the past month. The VanEck Semiconductor ETF, which tracks the broader chip sector, advanced 2 percent, partially recovering from the sharp 5 percent decline it suffered on May 12. The iShares Semiconductor ETF also gained. ON Semiconductor climbed 7.9 percent. The semiconductor sector's year-to-date performance of approximately 60 percent remains extraordinary by any historical comparison, and even the session-to-session volatility of recent days represents relatively modest pullbacks in the context of that broader trend.
Apple Incorporated touched $300 per share for the first time in its corporate history on May 13, hitting an intraday high of $300.49 before closing up approximately 1.8 percent. The $300 milestone was treated by market commentators as a significant psychological and analytical landmark, given the immense scale of Apple's market capitalisation and the symbolism of round-number price levels for retail investors. Across the broader S&P 500, 27 stocks reached new 52-week highs on May 13, including Analog Devices and Datadog, both hitting all-time records. At the other extreme, 44 stocks in the index reached new 52-week lows, including Charter Communications, which traded at its lowest levels since April 2014.
After the regular session closed, Cisco Systems reported third-quarter fiscal 2026 earnings that comprehensively beat Wall Street expectations. Revenue came in at approximately $15.8 billion, up 12 percent year-on-year. The company also announced an AI-focused restructuring involving the elimination of nearly 4,000 jobs. Cisco surged 19 percent in extended trading — a move that, when it carried into May 14 premarket activity, pushed Dow Jones futures up 351 points, or 0.7 percent, and appeared set to carry the Dow back above the psychologically significant 50,000 level it had visited earlier in the year. Cerebras Systems also priced its initial public offering at $185 per share — above the expected range of $150 to $160 — raising at least $5.55 billion in the largest AI chip company listing of the year.
Oil at $100: Elevated But Steady, With One Ominous Warning
Crude oil prices remained firm above $100 per barrel on May 13, with West Texas Intermediate settling near $101 and Brent Crude holding above $105. Both benchmarks remained well above their pre-conflict levels from February 2026, reflecting the sustained disruption of Hormuz shipping traffic and the absence of any imminent diplomatic resolution to the US-Iran war. Shell Chief Executive Wael Sawan issued one of the starkest oil market warnings yet, saying the world might have produced one billion fewer barrels as a consequence of the Iran war, and warning that the disruption could lead to oil shortages within weeks rather than months. That warning, if it materialises, would represent a significant escalation of the energy crisis beyond what markets have so far priced in.
Heading into May 14: Cisco, Beijing, and What Comes Next
As markets enter May 14, the dominant themes are clear: AI-driven technology optimism on one side, and geopolitical and inflationary risk on the other. Nasdaq 100 futures rose 0.2 percent overnight, pointing toward a potential third consecutive record high for the index — a streak that would rank among the most sustained runs of 2026. The Trump-Xi summit in Beijing, which reached its bilateral meeting phase on May 14, has produced early signals of agreement on Iran and on trade mechanisms, including a potential "Board of Trade" covering approximately $30 billion in non-sensitive goods. Whether those signals develop into concrete agreements capable of materially reducing geopolitical and energy market risk will determine the direction of global markets through the remainder of May and into the summer.
