Stocks
US stocks hit a new record high
The S&P 500 reached its first all-time high since August and finished the week up about 1.2%. It's now up around 14% for 2026, with the tech-heavy Nasdaq up about 18%.
Why it matters: A record high doesn't tell you a crash is coming next, or that one isn't. Nobody knows. That's why steady, long-term investing usually beats trying to guess the top.
Interest rates
Borrowing costs hit a 20-year high
The 10-year US Treasury yield climbed to its highest level since 2002. A big government bond sale paid investors 5.3%.
Why it matters: Higher rates make loans more expensive, but savings accounts and bonds pay you more.
The Fed
Another rate hike may be coming
Notes from the Federal Reserve's September meeting confirmed a unanimous quarter-point rate hike. Markets expect one more before December.
Why it matters: Central banks raise rates to slow down rising prices (inflation).
Tech
Worries about AI spending shake tech
Reports that OpenAI's revenue was weaker than expected briefly pulled stocks down, until the company said its forecast hadn't changed.
Why it matters: Companies are spending huge sums on AI, and investors are nervous about whether it will pay off.
Energy
Oil is up nearly 60% this year
A hurricane shut down about 1.3 million barrels a day of production in the Gulf of Mexico, and attacks on ships cut traffic through the Strait of Hormuz.
Why it matters: Oil prices show up in what everyone pays, from plane tickets to groceries.
Chips
Huge growth still disappointed investors
Chipmaker TSMC reported sales up 51%, and Samsung's profit rose nine-fold. Both still fell short of what investors were hoping for.
Why it matters: Stock prices react to results compared with expectations.
