Chipmakers carry Wall Street to records
Recent developments for chipmakers including Marvell Technology, Advanced Micro Devices and Broadcom showed growth in markets for chips powering AI, and investors responded with optimism.
- •S&P 500: up 0.58% at the close, topping 7,800 for the first time in its history
- •Nasdaq: up 0.45% to a record finish for the tech-heavy index
- •Dow: up 0.49%, sitting slightly below its record high from August
Rate hopes and a yield pullback
Expectations on Wall Street have shifted toward the US Federal Reserve leaving interest rates unchanged at its next board meeting in October. Hiring grew underwhelmingly in September, and multiple Fed officials have signaled the next interest rate increase can probably wait.
The 10-year US treasury bond yield, which had reached 5.349% on Monday - its highest since April 2022 - dipped back down on Tuesday.
Strain behind the optimism
Stock optimism, largely from continuing AI investment, has defied other signs of instability in the US economy and global politics. Turmoil has gripped the US bond market in recent weeks even though it is typically seen as one of the safest investment vehicles, and bond yields - the return an investor receives when a bond matures - have hit recent highs on concerns over high inflation and interest rates.
- •Gas prices, though down over the last week, remain about $1.20 a gallon above where they stood a year ago on average
- •Diesel, the fuel for trucks, buses and trains, has fallen from its record high yet still costs over 40% more than a year ago
Economy in the midterm spotlight
The economy is expected to be a top issue in the upcoming midterm elections, with many voters frustrated over high prices. Donald Trump has been stumping for Republican candidates across the country as he works to give voters a different economic picture. Speaking at a rally in Nebraska on Monday night, he said the nation was doing better than it had ever done. At the same rally, Trump said gas prices would fall below $1.85 a gallon "in no time".
