Over three weeks, Brazilian hedge-fund managers went from celebrating some of their biggest gains in years to reporting steep losses and issuing mea culpas to clients, with losses reaching 24% after the Lula shock, according to Bloomberg.

Major technology companies are making trillion-dollar bets on AI infrastructure, relying on continued growth in advertising, enterprise software and e-commerce to fund the investment as they await future returns. According to Sina Finance, the latest earnings reports showed pressure on core businesses and cash flow. Meta reported negative free cash flow of $2.12 billion, Amazon’s net cash outflow widened to $42.4 billion, and Alphabet’s reached $9.07 billion. Microsoft was the only one of the five hyperscale cloud providers to maintain positive free cash flow, though its cash generation fell 27% to $18.63 billion for a second consecutive quarter. Amazon expects capital expenditures of $220 billion this year, while analysts forecast more than $280 billion next year. Meta said its capital expenditures could reach $145 billion this year, and analysts expect them to exceed $210 billion in 2027. Microsoft said it would continue issuing bonds to expand its AI infrastructure investment. Alphabet recorded its largest-ever one-day share decline on Thursday, while Amazon shares fell in after-hours trading following its earnings report.

European natural gas prices have climbed to a nearly four-year high as EU storage levels fell to about 75%, the lowest for this time of year since records began in 2011. According to Sina Finance, the December-delivery Dutch TTF futures contract rose 4.9% on Friday to €102.78 per megawatt-hour ($115), after topping €100 on Wednesday. Trading Economics data show the contract gained about 36% this month and 256% this year. The last comparable price surge came in 2022, after Russia’s invasion of Ukraine triggered an unprecedented European gas crisis. TTF futures reached €139 per megawatt-hour on December 5, 2022, and briefly soared to €339 per megawatt-hour in August that year. Disruptions to shipping through the Strait of Hormuz hampered Europe’s efforts to replenish gas storage over the summer. BlackRock analysts wrote in an October 27 report that already-low inventories could leave European energy prices, which had risen 170% this year, vulnerable to further increases if winter is cold. Natural gas accounts for about one-sixth of the EU’s power generation. Peter Taylor, head of commodities strategy at Macquarie Group, said Europe is effectively betting on a warmer winter, an expectation linked to El Niño. He noted that years with El Niño have often brought severe cold snaps to the UK and continental Europe. Taylor said Europe would need a sufficiently warm winter to get through the season, while severe cold could intensify competition with Asia for gas supplies and put further upward pressure on prices. BlackRock said the impact of energy shocks is uneven, estimating that they have reduced European GDP by about 0.5%, compared with 0.1% in the United States, and that the gap could widen. Europe and much of Asia are more exposed to gas price shocks than the United States, which has domestic shale gas and LNG production.

Elon Musk and Mark Zuckerberg used “superintelligence,” a term promoted by U.S. President Donald Trump, on earnings calls, while executives at Microsoft, Amazon and Alphabet continued to say “AI.” According to Sina Finance, Trump signed a directive on September 29 requiring U.S. executive-branch departments and agencies to use “superintelligence” instead of “artificial intelligence”; this week, he called on Truth Social for “AI” to be barred from all relevant documents and other materials. At last week’s earnings calls, Tesla and SpaceX adopted the term. Musk said at Tesla that some humanoid robots looked impressive but used neither advanced AI nor superintelligence; in early October, he had renamed the rocket company’s AI division SpaceXSI. At Meta’s October 21 earnings call, Zuckerberg emphasized the company’s goal of “providing personal superintelligence to everyone.” Meta had established its Superintelligence Labs the previous year. Amazon CEO Andy Jassy repeatedly used “AI,” Microsoft CEO Satya Nadella described AI as one of the company’s three key priorities, and Alphabet CEO Sundar Pichai said AI investment was driving usage and overall user growth. In other communications, Microsoft’s annual report to shareholders used “superintelligence” eight times. IBM CEO Arvind Krishna used both “SI” and “AI,” while Intel CEO Lip-Bu Tan said superintelligence was behind unprecedented demand amid chip supply constraints. Palo Alto Networks CEO Nikesh Arora called a White House meeting on superintelligence a milestone, and Nvidia CEO Jensen Huang praised the White House Superintelligence Accord.

According to Jin10, the Trump administration has awarded contracts for nearly 41 million barrels of crude oil released from the national emergency petroleum reserve, completing a large-scale oil-swap program intended to curb surging energy prices after the Iran war began. The U.S. Department of Energy said Vitol and Exxon Mobil were among the companies awarded contracts. The awards mark the final tranche of the U.S. Strategic Petroleum Reserve's 172-million-barrel emergency release, the second-largest in U.S. history and part of a broader International Energy Agency plan to put 400 million barrels of oil on the global market. Since the war began, the United States has released 174.1 million barrels, exceeding its previous joint commitment with the International Energy Agency of 172 million barrels.

Aradhana Sarin, AstraZeneca’s chief financial officer, said the drugmaker uses AI in almost every aspect of its work. She discussed earnings, the company’s drug pipeline, dealmaking and its restructuring plan on Bloomberg Surveillance, according to Bloomberg.

Intel shares fell after its revenue forecast missed analysts’ estimates, amid weak demand for PC processors and supply-chain problems with data center components, according to Bloomberg. Reddit shares sank on plans to limit access to its forums to encourage users to register and deepen engagement. Executives are willing to sacrifice some reach for a smaller, more engaged audience, whose insights could be valuable to advertisers. Roblox shares slid after the company reported a year-over-year decline in player engagement following the deployment of stronger child-safety measures.

The plunge in shares of Meta, Alphabet and Intel has worsened losses for investors who bought into the companies’ mega-share sales, according to Bloomberg. The companies are among the biggest names in the artificial intelligence infrastructure boom.
