🌐 Markets Overview: Economy headwinds restrain markets
This week markets shifted focus from Middle East events to their economic consequences. The open question is whether economic news will become a persistent headwind.
US equities largely treaded water. The S&P 500 and Nasdaq briefly set records before pulling back Friday on inflation data. Energy led gains; consumer discretionary and real estate bore the brunt of rate-driven pressure. Small-caps underperformed, reflecting smaller businesses' sensitivity to borrowing conditions.
European indices fell as rising energy costs amplified already sluggish growth. Eurozone industrial output missed forecast in March, France's unemployment hit its highest since 2021, and Germany's ZEW sentiment remained negative.
Japan's Nikkei slipped on profit-taking in semiconductor names after strong recent gains. The more significant signal came from bonds: the 10-year JGB yield reached its highest since 1997, firming expectations of an imminent BoJ hike. The yen weakened further, erasing late-April intervention gains.
India's Nifty was the standout, recovering from a four-session losing streak on metals strength and improved sentiment around the Trump-Xi summit, before giving back some gains Friday as Brent crossed $109 and the rupee hit a record low.
Gold pulled back sharply as real yields rose.
WTI has recovered to above $100 after dipping into the low $80s in mid-April, stabilising near its post-March range.
🤖AI Stocks
Tech stocks were impacted by the market decline.
The semiconductor group split sharply. Nvidia added nearly 5%, extending its role as the benchmark of AI infrastructure sentiment.
Intel fell the hardest - down nearly 13% - on a combination of valuation concern after more than doubling over the prior month, UBS data showing server CPU market share erosion to AMD and ARM, and a KeyBanc note flagging a 27% drop in April notebook shipments from March. Q1 results, reported earlier in April, were a beat on revenue and EPS, but trailing profitability remains negative. The market is reassessing how much foundry optimism has already been priced in at current levels.
AMD declined despite a strong first quarter reported on May 5 - revenue up 38% year over year, data center segment up 57%, Q2 guidance well above consensus. The continued drift lower reflects two concerns flagged on the earnings call: management guided H2 gaming revenue down more than 20%, and the stock's valuation had expanded aggressively in the rally following results.
The data center thesis is intact; the question is the multiple it commands.
Among infrastructure names, Vertiv was the week's standout. The stock hit an all-time high on Monday following an investor day held May 12-13 and a wave of analyst price target upgrades - Citi, RBC, BofA, and Barclays all raised targets this week. Underlying the enthusiasm: Q1 results reported April 22 showed revenue up 30% year over year, adjusted EPS up 83%, and full-year guidance raised. As the most direct beneficiary of AI data center power and cooling buildout, the investor day reinforced confidence that demand visibility extends well beyond the current year.
Constellation Energy dropped sharply after an Argus analyst cut his price target by 18% to $350, citing the need to align valuation with utility-sector comparables over semiconductor multiples. Q1 EPS guidance came in slightly below consensus and Calpine integration costs are weighing on margins, pushing the market toward utility-style pricing. The long-term demand thesis - clean baseload power for AI data centers - is unchanged.
Macro Watch: This Week’s Economic Developments
🇺🇸 United States: April CPI at 3.8% year over year was the week's centrepiece. Energy drove the headline, but core inflation at 2.8% also surprised to the upside. PPI jumped 6.0% annually, the largest reading since March 2022. The expectations are that rate cuts are much further out.
Retail sales rose 0.5% in April, with the GDP-relevant control group also up 0.5%.
Jobless claims ticked up modestly to 211,000 - softening but not breaking.
🇪🇺 Eurozone: Industrial output for March grew 0.2% month over month, just below forecast, with Germany contracting while France, Italy, and Spain posted gains. France's Q1 unemployment climbed to 8.1%, the highest since early 2021. Germany's ZEW sentiment recovered to -10.2 from April's -17.2, beating expectations but remaining negative. Rising energy costs are adding an inflationary layer on top of an already fragile growth picture.
🇬🇧 United Kingdom: A politically turbulent week, with growing pressure on Prime Minister Starmer's leadership and questions over Labour's direction ahead of the next election. Sterling weakened on the instability. On the data front, retail sales fell 3.0% year over year in April, well below the 12-month average of 1.8% growth.
🇯🇵 Japan: The 10-year JGB yield rose to 2.72%, its highest since 1997, as market consensus firmed around a BoJ rate hike as early as June.
The yen weakened to around JPY 158-159 against the dollar, fully unwinding the gains from official intervention in late April and early May.
Corporate goods prices surged 4.9% year over year in April, well above the 3.0% forecast. Household spending fell 2.9% year over year in March, sharper than the 1.3% expected and a fourth consecutive monthly decline.
🇨🇳 China: The Trump-Xi summit concluded May 15 with signals of support for stable relations, commitments to increase US agricultural and energy purchases, and discussions around semiconductor and rare-earth supply chains. No major rollback of export restrictions was announced, but the constructive tone limited downside sentiment.
Chinese equities still ended lower as follow-through buying failed to materialise. April PPI rose 2.8% year over year - the fastest since July 2022 - while CPI edged up to 1.2%. Export growth came in at 14.1% year over year, with imports up 25.3%.
🌐 Artificial Intelligence and Tech
OpenAI moves into personal finance. OpenAI launched a personal finance feature for ChatGPT Pro subscribers in the US, letting them connect bank accounts, credit cards, and investment portfolios via Plaid, which covers over 12,000 financial institutions. Once linked, ChatGPT generates a spending dashboard and answers financial questions grounded in the user's actual data. The feature runs on GPT-5.5 and follows OpenAI's April acquisition of personal finance startup Hiro. ChatGPT cannot execute transactions or access full account numbers. It is the clearest signal yet of OpenAI's ambition to move ChatGPT from a conversational tool toward a personal operating layer for daily life.
xAI's Mississippi turbine problem deepens. Elon Musk's xAI now has 46 natural gas turbines at its Colossus 2 data center in Southaven, Mississippi - up from 27 when the NAACP filed a Clean Air Act lawsuit in April. The state classifies them as "temporary-mobile" because they sit on flatbed trailers, exempting them from air permits for up to a year. The NAACP this week asked the court for an emergency injunction, arguing the facility could be the largest industrial source of smog-forming nitrogen oxides in the greater Memphis area, a region already failing national air quality standards. The case turns on whether the "temporary-mobile" classification can serve as a permanent regulatory workaround.
Anthropic launched Claude for Small Business on May 13, a package of 15 pre-built agentic workflows and connectors to tools including QuickBooks, PayPal, HubSpot, Canva, and DocuSign - delivered as a toggle install within Claude Cowork. The target is the 36 million small US businesses that account for 44% of GDP but have lagged enterprise AI adoption. Anthropic's own survey found half of small business owners cite data security as their primary hesitation. The launch is supported by a 10-city US training tour.
Anthropic's 2026 revenue run rate has now passed $30 billion.
Notion bets on becoming the home for AI agents. Notion launched a developer platform on May 13 that repositions it from note-taking app to an orchestration layer for AI agents and workflows. New capabilities include Workers - a hosted environment for custom code - and an External Agents API that lets third-party agents from Anthropic, Codex, and Cursor operate inside the Notion workspace. Teams can also sync live data from Salesforce, Zendesk, and other platforms directly into Notion databases. Customers have already built over one million agents since the February Custom Agents launch, putting Notion in direct competition with Microsoft and Google for enterprise workflow infrastructure.
AI-generated disinformation targets UK audiences. A BBC Panorama investigation this week identified dozens of social media accounts running AI-generated videos depicting UK cities in decline, operated from Sri Lanka, Vietnam, the US, and locations linked to Iran and the UAE. One fabricated video drew 1.3 million views; a series of AI-generated "2050" walks through British cities has surpassed 20 million views combined. London Mayor Sadiq Khan told the BBC some operators are profit-motivated, others state-backed by hostile governments including Russia and China.
Crypto highlights
A mixed week for the top seven. The monthly picture offers some relief - most coins are up over four weeks - but year-to-date losses across the altcoin complex remain deep, ranging from Ethereum's 25% decline to Polkadot and Cardano well beyond that.
Bitcoin continues to hold relative value while altcoins absorb the brunt of risk-off positioning. That gap remains the defining characteristic of this cycle.
