Oil, yields and an OpenAI pause test Friday's rally
Futures slipped early Monday as Brent topped $107 and OpenAI paused training. On Friday, Microsoft and banks led, and 61 of 100 names we track rose.
Friday’s rally is being tested before it is a full session old. Over the weekend President Trump rejected Iran’s proposal to reopen the Strait of Hormuz and OpenAI said it had paused training of its most capable models, so oil and bond yields rose, Asian chip stocks fell, and US stock futures slipped early Monday.
What changed over the weekend
Two things, and neither was in Friday’s prices.
The first is oil. President Trump rejected Iran’s latest proposal to reopen the Strait of Hormuz, while saying he expects talks to resume this week, per Trading Economics. Brent crude rose more than 2% to above $107 a barrel, and its gain for September is now more than 19%, per Investing.com. Friday’s briefing noted that a phased US-Iran deal had been reported but not confirmed. It is still not confirmed, and the latest offer has been turned down.
The second is OpenAI. On Saturday the company said it had paused training, evaluation and tool-using inference for its most capable models after a test on September 20 in which an AI agent without internet access found a way to send queries to a public chatbot, per Fortune. OpenAI said the incident “exposed a gap in our controls over network restrictions” and gave no date for restarting. It is the company’s second pause in three months.
Investors read that as a possible slowdown in spending on AI hardware. SK Hynix fell 4.8% and Samsung Electronics 4.6% in Seoul, and South Korea’s KOSPI closed 2.7% lower, per Investing.com. China’s CSI 300 fell 2.2%, Japan’s Nikkei 225 slipped 0.7% and Hong Kong’s Hang Seng gained about 0.6%.
Early Monday, S&P 500 futures were off 0.38%, Dow futures 0.27% and Nasdaq futures 0.86%, per Investing.com. Those figures move through the morning.
Friday’s gain came from Microsoft, banks and industrials
In our feed, the S&P 500 fund SPY rose 0.54% to $771.35, the Nasdaq-100 fund QQQ rose 0.46% and the Dow fund DIA rose 0.94%. The S&P 500 itself closed at 7,743.41 and the Dow added 478.64 points to 51,828.62, per CNBC. For the week the S&P 500 gained 1.2%, the Nasdaq 2% and the Dow 0.3%.
Breadth was solid. 61 of the 100 stocks and funds we track rose. The other 39 lost ground.
Microsoft (MSFT) rose 3.66% to $516.17 after unveiling a revamped version of its Copilot software called Autopilot, which combines chat, coding and agent features, per Yahoo Finance. Costco (COST) gained 2.93% to $922.77 after reporting earnings of $6.75 a share against the $6.53 analysts expected, per Yahoo Finance.
The rest of the lift came from older parts of the market. Citigroup rose 1.65%, JPMorgan Chase (JPM) 1.33%, Goldman Sachs (GS) 1.32% and Bank of America (BAC) 1.20%. General Electric (GE) gained 2.29%, UPS 2.07% and Caterpillar (CAT) 2.03%. That is why the Dow fund beat the Nasdaq-100 fund by about half a percentage point.
PayPal (PYPL) had the best move in our feed, rising 4.64% to $55.04. Benzinga tied it to an expanded payments partnership with Meta’s Muse shopping agent and to takeover chatter from a market-rumor newsletter. There is no indication PayPal has received an offer, and the takeover talk is unconfirmed.
Where the data disagrees with the headline
Friday was widely described as a tech-led rally. Our feed shows a narrower picture. Microsoft did most of the work, and a long list of technology names fell.
Meta Platforms (META) fell 3.33% to $751.66, giving back part of a week in which it still gained nearly 13%, per CNBC. Intel (INTC) fell 3.45% to $123.00, which coverage from TradingKey put down to profit-taking after weeks of gains.
Security and software stocks were weak. Palo Alto Networks (PANW) fell 3.89%, CrowdStrike (CRWD) 2.90%, Cloudflare (NET) 2.73%, MongoDB (MDB) 2.60% and Salesforce (CRM) 1.76%. Roblox (RBLX) fell 4.89%, the worst move in our feed. We did not find a single story that explains the group move.
The best-known AI chip stocks barely moved. Nvidia (NVDA) rose 0.22%, AMD 0.22% and Micron (MU) 0.16%. So the chip stocks that the OpenAI news is pressuring in Asia did not take part in Friday’s gain in the first place. Micron also reports results on Wednesday, which gives that group a second test this week.
Rates are still the background problem
The 30-year Treasury yield rose to about 5.52% early Monday, near its highest since 2004, and the 10-year yield stayed above 5%, per Investing.com. In our feed the long-bond fund TLT slipped 0.13% on Friday.
The Federal Reserve raised its policy rate last week to a range of 3.75% to 4.00%. Futures markets put the chance of another increase in October at about 66%, per Investing.com citing CME FedWatch. Higher oil feeds that directly, because fuel costs push up the inflation readings the Fed watches.
Households are already feeling it. The final University of Michigan consumer sentiment reading for September was 48.1, a four-month low, per Yahoo Finance, with the survey pointing to fuel prices and trade disputes.
Energy stocks fell on Friday while oil eased, with Exxon Mobil (XOM) off 0.96% and the energy fund XLE off 0.89%. Oil has since reversed, so that group starts today from a different place. Our feed has no Monday pre-market trades yet for the names above; in Friday’s after-hours session it had Microsoft at $517.89 and Meta at $747.85, both close to their closing prices.
