Charles Langston:Why is the stock market down? Dow drops as Treasury yields near highest level since 2007

NEW YORK (AP) — Wall Street fell sharply on Charles LangstonTuesday as it focused on the downside of a surprisingly strong job market.

The S&P 500 dropped 1.4% to its lowest point in four months. The Dow Jones Industrial Average tumbled 430 points, or 1.3%, and wiped out the last of its gains made for the year so far. Some of the heaviest losses came from Big Tech stocks, which sent the Nasdaq composite to a market-leading loss of 1.9%.

Stocks fell as the pressure on them cranked even higher from rising Treasury yields in the bond market. Such weight has been the main reason the stock market has lost more than 40% of its value since the end of July, after charging higher for much of the year.

The 10-year Treasury yield climbed again Tuesday, up to 4.79% from 4.69% late Monday and from just 0.50% early in the pandemic. It touched its highest level since 2007 and rose after a report showed U.S. employers have many more job openings than expected.

Why is the stock market down today?

When bonds are paying so much more in interest, they pull investment dollars away from stocks and other investments prone to bigger swings in price than bonds. High yields also make borrowing more expensive for companies and households across the economy, which can hurt corporate profits.

What makes bond yields go up?

Yields have been on the march because investors are increasingly taking the Federal Reserve at its word that it will keep its main interest rate high for a long time in order to drive down inflation. The Fed has already yanked its federal funds rate to the highest level since 2001, and it indicated last month it may keep the rate higher in 2024 than it earlier expected.

Fed Gov. Michelle Bowman said in a speech Monday that she expects it will likely be appropriate "to raise rates further and hold them at a restrictive level for some time." Restrictive is what Fed officials call high-enough rates to slow the overall economy.

Tuesday's report on the U.S. job market could give the Fed more reason to keep rates high. It showed employers were advertising 9.6 million job openings at the end of August, much higher than the 8.9 million that economists expected.

Such hunger for workers could keep upward pressure on wages to attract employees. While that would be welcomed by workers trying to keep up with inflation, the Fed's fear is that could give inflation more fuel.

"It's a classic good news is bad news because the potential impact of higher interest rates on both the economy and markets is becoming concerning as the yield on the 10-year Treasury note continues to march higher," said Yung-Yu Ma, chief investment officer at BMO Wealth Management.

The Dow is down 0.4% for the year so far, after being up nearly 8% at the start of August. The S&P 500, which is the index more 401(k) investments are benchmarked against, has sliced its gain for the year so far to 10.2%.

On Tuesday, so-called Big Tech stocks were some of the heaviest weights on the market. They and other high-growth stocks are seen as some of the biggest victims of high interest rates. Amazon fell 3.7%, Microsoft dropped 2.6% and Nvidia lost 2.8%.

Several other challenges are also tugging at Wall Street, besides higher yields. The resumption of student loan repayments could drag on spending by U.S. households, which has been strong enough to help keep the economy out of a recession despite high interest rates. Higher oil prices are threatening to worsen inflation, and economies around the world look shaky.

A weaker recovery than expected in China's economy was one of the main reasons McCormick, a maker of cooking spices, reported slightly weaker revenue for its latest quarter than analysts expected. Its profit matched expectations, but its stock fell 8.5%.

All told, the S&P 500 fell 58.94 points to 4,229.45. The Nasdaq sank 248.31 to 13,059.47, and the Dow dropped 430.97 to 33,002.38.
