A trend is a fact that keeps showing up on the tape — not a hot tip and not a reason to empty a brokerage account on Monday. The S&P 500 closed above 7,800 for the first time on Tuesday, October 6, then slipped to 7,765.36 on Thursday, October 8. That number is mood. The five stock market trends below are the business underneath it.
1. AI spending is still the engine — and one report shook it
Earlier this year Amazon said it expected about $200 billion of capital spending across its businesses in 2026, citing AI, chips, and robotics. Capital spending means money spent on buildings, chips, and power — not a dividend. Chipmakers have gained more than 80% this year, according to Reuters.
On October 8, the Financial Times reported that OpenAI’s annualized revenue was approaching $50 billion — roughly $20 billion below figures reported a few weeks earlier. The Philadelphia Semiconductor Index fell 3.39% that day, and Nvidia lost 2.9%. A report about one private company is not an earnings print. Price is mood. Value is still the business — customers, cash, and whether the spending pays back.
2. Third-quarter earnings season starts with a high bar
As of October 2, FactSet expected S&P 500 earnings to grow 29.5% from a year ago in the third quarter, on revenue growth of 12.3%. If that holds, it is the third straight quarter of earnings growth above 25%. All eleven sectors are expected to grow. Of the 116 companies that issued guidance, 72 guided up. The big banks start reporting on October 13 — the day-by-day list is in upcoming earnings next week. A high bar is easier to trip over. A beat is not a buy.
3. The Fed is hiking, and bond yields hit 2002 levels
An interest rate is the price of borrowed money. On September 16, the Fed raised its target range by 0.25 point to 3.75% to 4% — its first hike since July 2023 — and said inflation remains elevated. On Monday, October 5, the 10-year Treasury yield passed 5.3%, its highest since 2002. It closed near 5.23% on October 8. Fed Governor Christopher Waller said that day he anticipates additional hikes if the data come in as expected. The next Fed meeting is October 27–28, and September CPI is due October 14. Higher rates make bonds compete with stocks — more in how Fed interest rates affect the stock market. That is the trend. It is not a reason to panic-sell the 401(k).
4. Breadth is narrow — a few giants carry the index
Breadth means how many stocks are participating, not just how far the S&P 500 traveled. Between the August 13 record and October 5, about three quarters of S&P 500 stocks were down, according to FactSet data cited by CNBC. Over that stretch the regular S&P 500 rose about 1%, while the equal-weight version — every stock counted the same — fell nearly 5%. The Magnificent Seven make up more than 34% of the index’s market value. A market that only lifts a few giant names is a mood trade. A broad index fund owns both the giants and the laggards.
5. Oil and the Strait of Hormuz are still the volatility switch
Oil crossed $100 a barrel in March as the Iran conflict disrupted shipping through the Strait of Hormuz, fell below $70, then climbed back above $100 in early September. On October 8, Brent rose 4.07% to $104.28 and U.S. crude settled at $91.49. Energy feeds inflation, which feeds the Fed, which feeds every multiple on the S&P 500. Headlines can swing oil both ways in a single afternoon. Same-week lottery calls are how beginners donate the debit.
